ALBERT | REMOTE ALMOST ANYWHERE IN THE WORLD| Hiring principal and distinguished engineers to build net new products | up to ~ $750k Hiring: exceptional consumer product engineers at Albert.

We're a consumer fintech with 25M+ users who trust us to budget, save, invest, and bank in one place. Profitable for 4+ years. And as of today, our average employee tenure is 3.6 years, a number you almost never see in startup tech, and one we're quietly proud of. People stay because the work is good, the people are sharp, and we've built something worth staying for.

Now we're building net-new consumer products from zero, and we're looking for people who love to tinker and build stuff to ship them with us.

The kind of person we're looking for: • Top fraction of a percentile in craft, the kind of good that's hard to fake • Builds for fun, not just for work. The kind who ships a working prototype over the weekend and can't help themselves • Comfortable owning 0 to 1 consumer products end-to-end • Allergic to politics, theater, and bureaucracy

What you get: • Remote, anywhere with reasonable timezone overlap (and for someone truly exceptional, we'll make async work) • Real scale from day one (20M+ users, real money, real consequences) • Compensation that beats the market. We pay well and we mean it. Base, discretionary year-end bonus, meaningful 401(k) match, and meaningful equity in a profitable, growing unicorn (the kind that's actually worth something) • Platinum PPO health benefits with Blue Shield, top of the top of the line, covering your entire family • A mission worth your time: make money simple, so people spend less time managing it and keep more of it • Small senior-heavy teams, direct ownership, no layers • Forthcoming with the business metrics that matter, so you always know how the company is actually doing • The startup perks done right: catered lunches, wellness stipend, team offsites, casual dress. The stuff that compounds when you're showing up engaged for years, not months • Profitable for 4+ years, so you build with conviction, not runway anxiety

Stack: python, claude, postgres, react.js /react native

If this is you, email us at recruiting@albert.com

Edit: we are in the process of rebuilding our career site to speak to how we hire (e.g. hunt, dont post, find the best). Just an FYI

Also, we carefully review every application. If we think there may be a fit, we'll reach out within a few business days. Either way, thank you for your interest in what we're building and for taking the time to connect with us.

BOSS-IQ | CTO Partner | REMOTE (worldwide) | Full-time | Istanbul-based company | https://boss-iq.com

BOSS-IQ is an AI strategic-planning product for owner-operators of small and medium businesses. The boss describes an idea that has been stuck for years; a research-and-question session returns an implementation-ready plan. In production since June, hand-onboarding our first paying customers since August, invitation-only.

I am looking for a partner rather than a first hire, and I need two things in one person. An experienced developer who has genuinely run software in production — deployments, incidents, on-call. And a black-belt prompter. I mean that as a level, not a flourish. The tell: if you watch other developers work in AI environments and feel real frustration — everyone prompts, most prompt badly — and you have quietly built your own standing rule files, your own context discipline, your own reusable prompt library, then you already know what I am describing. That is the rarer of the two skills, and the one I weight hardest.

Under the product, 60+ specialist agents run continuous extraction over each customer's documents and sessions into a persistent, per-company memory: every fact dated and traced to its source sentence, contradictions kept rather than overwritten — a discipline we call Total Capture. Patent-pending since July, in context engineering.

Stack: TypeScript throughout. A NestJS API plus a separate NestJS worker on Railway, Next.js 16 / React 19 on Vercel, Postgres with Prisma, Redis and BullMQ, Pinecone, S3-compatible storage. Agents are LangChain.js / LangGraph ReAct agents on Anthropic Claude across three model tiers, with OpenAI embeddings. Every prompt body and model config lives in one versioned master file synced to LangSmith, never hardcoded in TypeScript.

I am the founder, and not an engineer — thirty years a strategy consultant, first terminal at the end of 2022. A contract developer built the first ~20,000 lines between December and February. Since February I have been the only developer, and it is now about 264,000 lines of TypeScript. I wrote the prompts first, 18,500 lines across 79 agent files, and the code came after to serve them.

That was the environment, not me: 45 interconnected instruction files deploying sub-agents, around 300,000 words of standing rules, orchestrated by one always-on kernel that classifies each session, auto-attaches the rules matching the files being touched, and generates sub-agentic plans for the work.

Compensation is the honest startup shape: generous equity, austerity salary. No number here — it is set against what you currently earn, and that is a conversation rather than a billboard.

Full posting: https://boss-iq.com/cto-partner.html

Apply: https://boss-iq.com/apply-cto.html — one question at a time, ending by asking you to write the prompts you would use on day one, not code. I read every one myself.

AiMi | Full Stack AI Engineer | Remote(Everywhere) | Full-time

AiMi builds agentic AI infrastructure for capital markets: autonomous agents that ingest venue and vendor notifications, assess impact across client infrastructure, and drive change management workflows in real time, replacing what used to be manual, static processes for exchanges and their ops teams. live production platform, not a pilot.

you'd work across the full stack: React/TypeScript frontend, Node.js backend, AWS Lambda. concretely: shipping features in the agent pipeline, building MCP-based connectors and skills that extend what our agents can reach, running evals on agent accuracy and reliability, building observability and alerting for agent latency/error rates/failed workflows, and making long-running LLM, agent, and SSE calls actually resilient (timeouts, retries, circuit breakers, fail-fast, recovery). also a fair amount of diagnosing dependency/version conflicts in a Node.js/npm monorepo, which is its own skill.

looking for 2-3+ years hands-on experience, solid Node.js and REST API background, real hands-on work with LLMs or agent frameworks (Mastra, LangChain, LlamaIndex, Claude, OpenAI or similar), comfortable with AWS (Lambda, Bedrock, DynamoDB, S3, Cognito, API Gateway, CloudWatch), MongoDB/DynamoDB, and genuinely tests what you ship (unit, integration, e2e). familiarity with spec-driven development (Claude Code, Cursor, CodeRabbit or similar) is a real plus since that's how we work day to day. bonus points for capital markets/trading infra background, LLM observability tooling like Langfuse, SSE streaming experience, or PostHog.

you'd be working on great things here: real architectural decisions at an early-stage company, visible impact from week one, and room to grow into a senior or lead role as we grow.

Trax | https://www.traxtech.com/ | Onsite Cebu PH, Remote Costa Rica, Remote US are possible | Full-time | Architect

I work best as a team - with someone who can challenge my assumptions and bolster my weaknesses. I'm looking to increase the bandwidth of the architecture function at Trax, as I can't do it alone!

We BOTH need to be strong in: * Communication - we lead by influence, not by authority. Kindness is required! * Ego-free problem solving - good ideas come from anywhere. * Reliable software designs - things that work on dirty data, incomplete testing, and AI-enabled development workflows. * Building the first prototype in an area with zero guidelines - careful choices and evaluation of vendors, setting an example to follow.

You should be strong in: * Angular, Vue, Javascript, and web serving best practices for development organizations for long term health. * Developer enablement and tooling in the Node.js ecosystem - shared component architectures, design systems, etc. * Data-heavy applications and their operation and security needs.

I am strong on the infrastructure, DevOps, k8s, and backend and data stacks. So don't worry about relative weaknesses there, though you will need some understanding.

This would be a good first architecture position for a Staff or Senior Staff level full-stack technical leader who wants to expand their scope. My email is in my profile!

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.

For September 2026: 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.

Duets Network | Founding Engineer | REMOTE (US) | Equity + discretionary cash | ~10–15 hrs/wk

Duets Network is an AI-powered platform connecting startups and investors across the sports and entertainment industries. We are building a dynamic ecosystem that bridges founders, capital, and strategic partners to drive meaningful growth and collaboration at the intersection of technology and culture.

The initial product is built out, and we're now looking for a fractional Founding Engineer to guide the technical side moving forward: architecture, infrastructure, data/recommendation systems, security, and scalability.

Our founding team: CEO, ex-Universal Music Group; CBO, ex-Andreessen Horowitz. You'd work directly with the founders, with no existing engineering org, and would:

- Assess and improve the existing React / Node.js / PostgreSQL / AWS codebase and infrastructure

- Set engineering architecture, standards, and technical priorities

- Design the data + recommendation/scoring layer behind founder/investor/partner matching

- Build out DevOps, CI/CD, monitoring, and deployment processes

- Make pragmatic build-vs-buy decisions and coordinate external engineers/vendors as needed

- Serve as the primary technical team member, with real influence over the technology foundation and future engineering org

We're particularly interested in someone who has owned architecture end-to-end. Ideally with experience in matching, recommendation, ranking, or scoring systems. You should be comfortable explaining technical tradeoffs to non-technical founders and investors.

This is a fractional role (~10–15 hrs/wk), compensated with equity plus discretionary cash. It's a fit if you want the opportunity to be an early technical team member without a traditional full-time commitment. We're early-stage and moving fast, so you don't need to check every box, we're looking for someone curious, adaptable, and excited to build with us.

If interested, email team[at]duetsnetwork[dot]com with "Founding Engineer" in the subject line.
