InfoHawk | Software Engineer | London, UK or NYC | HYBRID (UK or US), occasional onsite | Full-time | https://www.infohawk.com

Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...

You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.

We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.

Axmed | AI Engineer (Agentic Systems) | REMOTE (preferred CET ±2: Spain, UK, Poland, Romania) | Full-time

Axmed runs a live B2B marketplace connecting healthcare providers in low- and middle-income countries with pharmaceutical suppliers, working to make sure geography and income never stand between someone and the medicine they need. Backed by the Gates Foundation and Founderful. We're past proving it works and into scaling it — this role is what takes us there.

You'll design and ship autonomous agents that run real steps of the marketplace (sourcing, quoting, order matching, supplier follow-up) on real transactions and real money, with a human in the loop only where risk demands it. Not research: you consume LLMs via API and build the judgment, guardrails, and monitoring around them, end to end, and own what you ship.

Stack: Python, LangChain/LangGraph/LlamaIndex/CrewAI (your choice), LLM APIs, cloud infra, CI/CD.

No visa sponsorship/relocation.

Apply: https://axmed.teamtailor.com/jobs/8175859-ai-engineer

Elman (Deep Science Ventures) | Co-founder & CTO | London, UK-based preferred / REMOTE considered | Full-time | Pre-seed

We're building AI to predict clinical trial and drug development outcomes, and quantify how much confidence those predictions deserve. By linking the evidence available at a decision to the judgement made and what happened next, we aim to learn which experimental findings predict outcomes in which therapeutic settings. The platform is already running, with work from an Allen Institute collaboration described in this preprint https://elman.ai/preprint.

We want a hands-on technical co-founder to lead development, build the evaluation programme and hire the first technical team once funded. Benchmark design, applied statistics and production LLM systems. The modelling approach is open. Biology experience useful, not required.

Founder equity.

Role and application: https://elman.ai/hn

Revieve Oy | Senior Product Engineer | REMOTE [Europe / (GMT+2)] | Contract, full-time |

Revieve (Helsinki, with a US office and a team in Asia) builds AI, AR and computer-vision personalization for beauty brands and retailers: skin analysis, virtual try-on and product recommendations. We work with 120+ brands and retailers in 40+ countries, and our product reaches millions of end users.

We're a small team (30+ people, about a dozen engineers) spread across eight time zones, and we've reorganized around the idea that one builder with the right tools can do what a team used to. This role exists because we believe that.

A typical week: a real customer problem lands in front of you with full context, and you decide what to build. Tuesday you sketch it in an AI design tool and prototype in Claude Code. Wednesday it's on staging and you send the founders a Loom. Thursday it's in production. About 1-2 hours of meetings a week, mostly async. No standups, no sprints, no PM or designer in the loop.

What we're looking for:

- Public proof of building: repos, products or side projects we can click around - AI in production, with an opinion about agents, evals, latency and what fails - Fluency with agentic coding (Claude Code, Codex, MCP, custom harnesses) - Design taste: you can take an idea to a working interface without a designer - Generalist instincts: TypeScript/React up front, comfortable with backend integrations and infra - Clear written thinking: READMEs, PRs, post-mortems

Process: intro call, then a paid build session where we work on a real problem together (that's where the hire decision happens, for both sides), a short presentation to the team, then an offer.

Perks: flexible hours, performance-based option plan, equipment budget, five weeks' vacation, paid parental leave.

You’ll own:

* B2B growth and go-to-market * Finding and closing early employer customers * Partnerships and strategic relationships * Building our first repeatable sales engine * Working directly with the CEO and founding team

We’re looking for someone who has actually brought customers to an early-stage company, and knows how to open doors, sell, build relationships, and execute without waiting for instructions.

Compensation: Equity-only at this stage. No salary yet.

This is a true founding opportunity. You won’t be joining an existing growth team, you’ll build it.

Opaxa | Founding Engineer, Forward Deployed (full-stack) | San Francisco Bay Area preferred, REMOTE (US) considered | Full-time | $175K–$225K + 0.5%–1.5% equity | opaxa.com

Every business with many locations already has systems that record what happened yesterday. None of them tell the manager what to do today. Opaxa does. It reads the systems a business already runs, learns how that operation actually works, and puts the right decision in front of the right manager: how busy tomorrow will be, who to schedule, what to order, which invoice overcharged you. Then it tracks what each decision earned.

Our founder runs a restaurant company with more than 40 locations and over 750 employees. Opaxa was built inside it to solve its own problems, and it runs there every night. We're well funded and now expanding to other multi-location operators: restaurant groups, stadiums and campuses, hotels, retail.

You'd be the second engineer, working with our founding engineer, who owns the architecture, and with the sales and product team. You'd take new features from spec to production, spend real time with the managers who use them, and turn what they tell you into shipped changes within days. As we bring on new clients, you'd lead getting them live. TypeScript/React, Python, Postgres, AWS, and AI tools every day.

This is an early, high-intensity role for someone who wants a lot of ownership and to move fast. US work authorization required. No agencies or contract firms.

To apply, email colton@opaxa.com with the subject "Forward Deployed: your name, your city" and include: your resume or LinkedIn; a link to something you built that real people use, and what you personally did on it; two or three sentences on a time a user's feedback changed what you shipped; and where you're based. We read every email.

Footprint | Rust Engineers (Backend, Infrastructure, Security) | New York, San Francisco | ONSITE | VISA (case by case) | $180K-$260K + equity

We build Percy, an agent that runs financial-crimes investigations for banks and fintechs. It clears false positives, escalates real risk, and writes the case narrative and audit record a regulator will read. Under it sits four years of identity infrastructure: verification, an AWS Nitro Enclave-backed vault for PII, and the APIs our customers call directly. The backend is Rust.

We're hiring three Members of Technical Staff:

- Backend: the Rust APIs and services behind verification, vaulting, and the checks Percy runs. Production Rust is ideal; deep systems experience plus a real wish to learn it also works. Crypto or systems-security background counts for a lot.

- Infrastructure: own agent compute, isolation, deploys and observability across Rust services and long-running agents. Rust, Postgres/Aurora, AWS (ECS/Fargate), Pulumi/Terraform, Datadog, OpenTelemetry.

- Security: protect identity data we vault on behalf of regulated banks and fintechs, and prove to auditors every step was done right.

Small, senior team. Backed by QED, Index and BoxGroup. Customers include FDIC- and OCC-regulated banks plus Bilt, Nuvei and MoonPay.

Apply: https://jobs.ashbyhq.com/footprint. I'm the recruiter and will answer questions in this thread.

Pond AI | Head of Engineering (founding-level) | San Francisco | Onsite | Full-time | https://joinpond.ai

Most non-tech businesses know exactly which workflows they want AI agents to handle, but have no one to build, connect and run them. Pond delivers custom AI agents to these businesses through a network of 7k AI builders, with Pond as the platform and security layer over MCP.

We're backed by Tier-1 VCs and a co-inventor of GPT, and we're looking for a hands-on technical leader to own the platform end to end.

You'd be a great fit if you:

- Build full-stack and ship AI agents in production (TypeScript/Python, LLMs, tool use)

- Have worked on payments, agent coordination/MCP, or platform/marketplace products

- Have early-stage startup experience (founder, founding or early engineer) and like to grind

Email dylan@joinpond.ai with something you've built.

Mattermost | Remote (US and Canada) | FT | Multiple roles

Mattermost (https://mattermost.com) is an open-core collaboration and workflow automation platform for air-gapped, on-prem and private clouds. Our customers are in defense, intelligence, security and critical infrastructure, including the USAF and NASA. Y Combinator led our Series B, their largest open-source investment at the time.

Both openings are full stack on the core platform: Go backend, React/TypeScript frontend, PostgreSQL and Redis. The codebase is public (https://github.com/mattermost/mattermost), so most of what you build is too. We would rather hire people who ship and own complex software end to end than chase an exact stack match, so any systems or backend language and any frontend stack counts. What we look for in both roles: REST and WebSocket APIs with real networking fundamentals (HTTP, connection lifecycle), and relational databases including schema design and query optimization.

We use coding agents daily (Claude Code, Cursor, and others) at every stage of the work: planning, building, reviewing, testing, and shipping. We treat that as core craft rather than a shortcut around the fundamentals. If you have a track record of shipping and owning complex software end-to-end, we want to hear from you.

Senior Full Stack Engineer $142,723 - $172,723 USD Architect and ship full stack features end to end, own the testing strategy for what you ship, and build internal tooling and testing infrastructure that makes the rest of the team faster. You will work without close supervision and hold the security and compliance bar our customers require. Nice to have: distributed systems and high availability architecture, regulated-environment security, open-source contributions, experience on remote-first teams.

Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5379251008

Staff Full Stack Engineer $172,724 - $227,135 USD Set technical direction for the platform rather than for a feature area: architecture and roadmap across the stack, the standards for how the org uses coding agents, and the strategy for internal tooling and testing. You will influence direction across teams, partner with security and compliance on it, and mentor senior engineers. Nice to have: staff, principal or tech lead experience elsewhere, open-source maintainership, FedRAMP or ITAR familiarity, defense or critical infrastructure background.

Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5405811008

Both roles have Canadian postings: https://job-boards.greenhouse.io/mattermost

Prophet Town LLC | Various Software Engineering Roles | US – Remote and Hybrid | English fluency required | Full-time | $140K-$264K annual total comp (multiple)

We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds: we’re still coding. Notable recent projects include a gigantic ERP migration for Anduril, and working with Surge Labs to help develop some of the frontier LLM models from the big guys themselves (yes, seriously). This is a remote-first agency, but some projects involve onsite work.

I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership.

We continue the hiring push we were running last month too: our current work would especially benefit from from ai-forward senior engineering expertise that can design RL benchmarks, red-team model outputs, and create rubrics to evaluate and enhance the agentic coding capabilities of various frontier models. We received 216 applications in our August posting, and issued offers to approximately 10 (still following up with a few).

Applicants must meet a high bar - I intend to have a personal relationship with every hire. In return you’ll get:

  * Flexibility and a low-bureaucracy environment

  * Clients that won’t treat the vendor like “the B Team”

  * The chance to act as a code architect, not just implement tickets

  * Exposure to a wide variety of industries and modern     challenges

  * Me as your personal champion and advocate

Feel free to submit, even if you already did in the past.

Current roles available:

Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)

Tier 3 roles are typically 5-10 years experience with $140-$180K total comp. Tier 4 roles are 11-20 years experience, $210-$264K total comp. Higher tiers exist, and we always welcome exceptional applications.

Role: UX/UI Designer (BAY AREA, CA - HYBRID) 1099 CONTRACT APPLY: https://vuetech.sh/careers

Ongoing contract across several B2B products on one design system. First pass is a fixed-price flows-and-kit package, then hourly as each product grows. Not a full-time seat.

Engagement: Ongoing 1099 contract. Milestone prices are set against a frozen spec. This is not a full-time seat.

First package: A fixed-price flows-and-kit package, about three weeks. After that, $50–75/hr as each product grows.

Location: SF Bay Area, hybrid, with in-person working sessions for kickoff and reviews.

Start: Immediately after selection.

Level: Mid-level welcome. You work directly with the founding CTO. Early sessions are for breaking the product down together. After that, scope is deliverable by deliverable.

ABOUT THE STUDIO: We are a small Bay Area product studio. Several products, one stack, one visual language. You own the UX with us: who the user is, what they are trying to finish, what belongs on each screen, and what happens when it fails. Later products reuse the same tokens, components, and patterns so customers and our engineers are not learning a new UI every time.

The products are B2B web apps: dashboards, media and content libraries, status views, and auth and access-gate states. The first product in the queue is a digital signage CMS. Store owners upload content, build playlists, pair outdoor Android screens from a phone, and see what is playing. The app is a mobile-first PWA. The screen on the sidewalk has its own states: setup QR, downloading, no content, and error.

You take a real part in that breakdown. Bring a point of view on structure, priority, and what to cut. Sit with us and map the flows before the high-fidelity screens exist. When a familiar admin layout is the wrong job for the task, say so and show the alternative.

The screens still have to ship. We start from a Tailwind UI / shadcn component kit. Buttons, inputs, tables, cards, and dialogs stay that anatomy, restyled with our brand: color, type, radius, and density. Page structure, hierarchy, and flow are yours. Every screen is composed from those components, with tokens that map to our Tailwind theme, so the frontend team builds from the system.
