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.

Paradromics | Embedded Software Engineer | Austin, TX or Oakland, CA | Onsite | Full-time

Paradromics is building a high bandwidth brain-machine interface for clinical use. The implant we built is restoring function to patients by streaming out neural data from specific brain regions in real time, which we convert to e.g. speech using machine learning. Check out our recent article in the NYT: https://archive.ph/C6CRb .

We're looking for help in further developing and hardening our embedded Linux components, which work in tandem with FPGAs and our custom ASICs to read out neural data. Some of the ongoing efforts are: HIL testing on real devices, integrating new sensor ASICs, maintaining our Yocto build system, exploratory work on prototypes, improving our clinical UX, and improving the core code that receives and massages data. The code is largely written in Rust with a little Typescript, (and bash, and bitbake recipes, etc).

You'll be expected to have experience constructing reliable and understandable software in Linux, and some level of experience in building and interacting with embedded hardware. Rust experience is ideal but not necessary. We're not looking for a specific number of YoE, but for motivated and hungry engineers who want to push the frontier of brain-machine interfaces.
