ABOUT THE JOB
We’re removing one of the last great barriers to progress in the physical world.
While software moves fast, industries like aerospace, healthcare, and energy are still slowed by outdated, manual systems.
We are rapidly growing in stealth with 6-figure revenue, backed by a 14× oversubscribed $4.5m seed round from Tier-1 VCs such as Coinbase, Reddit, Klarna, and Spotify. Our world-class team includes former unicorn founding engineers and talent from X, Google, Amazon, and Yandex. We value people who want to win and thrive in high-ownership environments.
We’re building the system that lets complex, real-world work move at software speed.
WHO WE ARE LOOKING FOR
We’re looking for a Fullstack Engineer who thinks in user workflows, not tickets or isolated features.
This is a role for someone who wants to decide what should exist, build it end-to-end, and put it in users’ hands.
You will fit right in if you have experience with:
Product Engineering — Design and build end-to-end user workflows, from UI to backend logic and data
User Experience — Translate complex real-world processes into clear, intuitive interfaces
Frontend — Build production-grade UI using modern frontend frameworks (React, TypeScript)
Backend — Implement APIs, business logic, and data models that support complex workflows
AI Integration — Design and integrate AI-powered features (LLMs, agents, model-backed APIs) into user workflows
Product Judgment — Be opinionated about what to build, what not to build, and when to ship
Ownership — Build fast and ship production-grade systems with high ownership
WHAT YOU WILL DO
Ship from Day 1 — Deploy to production immediately and own real product surface area
Own it end-to-end — Create specs, figure things out, and build features end-to-end
Solve real problems — From UX polish to backend logic to jumping on customer calls
WHAT WE ARE LOOKING FOR TECHNICALLY
Strong experience with TypeScript and modern frontend frameworks (React or equivalent)
Comfortable building backend services in Python
Experience integrating AI systems (LLMs, agents, model-backed APIs) into production products
Ability to reason about complex workflows, not just CRUD
Strong plus if you have:
Founder or ex-founder experience
Early-stage or stealth startup background
Founder fellowships or similar environments (EF, YC, Antler, etc.)
Experience building AI-powered products in production
Experience working where requirements were unclear and evolving
YOUR FIRST MONTH
Ship to production from day one
Own problems end-to-end, from definition to deployment
Do what needs doing, including UX polish, debugging, and customer interaction
WE OFFER
Pace and purpose — In-person in London (visa sponsorship available)
No friction — Relocation, visas, meals, and tools fully covered
