Senior Full Stack Engineer

Location: San Francisco, California, United States, Sunnyvale, California, United States

Workplace: on_site

Employment Type: full

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
