# Senior Full Stack Engineer

> Supplied Talent · San Francisco, United States · Full-time · Posted 2026-07-01

**Workplace:** on_site

## Description

We're investing heavily in a new product area: browser automation and document intelligence. You'll own this platform end-to-end — from architecture through shipping. This is not a maintenance role. It's 80% net-new build, with the chance to put your fingerprints on a product line that's already live with customers and growing fast.

You'll report directly to the CEO (we're flat), work closely with product and forward-deployed engineering, and selectively join customer calls when you're the subject-matter expert on something you've built.

**WHAT YOU'LL BUILD**

•      Own the browser automation and document intelligence platform from the ground up

•      Build and ship AI agents that handle complex insurance workflows across voice, chat, email, and SMS

•      Write production-grade TypeScript/React/Node.js — first PR to production in week one

•      Work cross-functionally with product and forward-deployed engineering teams

•      Join customer calls to demo features you've built and advise on technical implementation

•      Shape architecture and tooling decisions as one of the earliest engineers at a company scaling fast

•      Help define engineering best practices as we grow toward 30 people by end of year

**WHAT WE'RE LOOKING FOR**

**Experience**

•      4–8 years of full-stack engineering experience, with clear ownership and progression

•      The profile that fits best: someone already performing at a senior level, ready to make the jump to full end-to-end ownership and responsibility

•      Strong foundation from a reputable tech company or well-known startup — we value quality of experience over years

•      Proven ability to ship AI or LLM-based products in production — this is non-negotiable

**Technical Skills**

•      Proficient in a modern language; willingness to work in TypeScript/React/Node.js/Express (our stack)

•      Hands-on experience building or integrating LLM-based systems, agents, or AI workflows

•      PostgreSQL or similar relational database experience

•      AWS or cloud infrastructure experience is a plus, not a requirement

**Academic Background**

•      GPA 3.7+ preferred for candidates earlier in career — we may request a transcript

•      School prestige matters less than how you performed there; what we want to see is that you've pushed yourself

**Who You Are**

•      You want ownership — not a ticket queue, not a committee. You want to build and see it land with real customers

•      You're comfortable being customer-facing and can speak credibly to technical decisions you've made

•      You thrive in a high-intensity environment and want to be part of building something from early innings

**TECH STACK**

**TypeScript**

**React**

**Node.js / Express**

**PostgreSQL**

**AWS**

We prioritize expertise in your language of choice and the appetite to work in our stack — we won't disqualify you for coming from a different language background.
