Fullstack Developer

We are looking for a Fullstack Engineer who can deeply understand and reconstruct complex product experiences from UI structure and user workflows, to backend APIs, data modelling, and system behaviour. In this role, you’ll replicate production‑grade SaaS platforms and wire them up to our backend systems and AI agents. You’ll work in a tight team of three to build interfaces and workflows that feel indistinguishable from the real product, but operate on synthetic or proxy data models. This is a high impact, high‑ownership role with fast iteration cycles.

Background

As a Fullstack Engineer, you’ll be working on developing advanced computer‑use environments used in developing AI models. Here we work with frontier AI labs to train their models to engage in the most valuable tasks of tomorrow. You will work on the edge of the AI data industry and learn valuable skills to push the development of advanced AI. Note: This role does not require any AI / Computer‑Use model training experience.

What You’ll Do

• Develop end‑to‑end products and workflows (such as tables, expenses, reimbursements, billing flows, and organizational management)
• Implement React frontends with clean, maintainable TSX component systems
• Build and integrate backend services including REST APIs, session management and auth flows, database schema design and implementation, and service wiring and state handling
• Work with data to demonstrate functional workflows without requiring live integrations
• Own feature development end‑to‑end, from architecture → implementation → testing → polish
• Conduct code reviews and uphold a strong engineering quality bar within the team

Example Scope

You may be tasked with replicating core workflows from the Ramp platform: Expenses & Reimbursements lifecycle.

• Virtual card creation + request flows
• Employee / org management dashboards
• Billing & accounting pages with filtering/sorting/state flows
• Navigation + interaction patterns matching real UX

Reference design surface: https://try.ramp.com/home

The goal is a real and functional product experience used to train advanced AI models, for example OpenAI ChatGPT and Anthropic Claude, to navigate these environments to complete valuable tasks.

What We’re Looking For

Professional software engineering experience in production systems.

• TypeScript
• React or similar frontend framework
• FastAPI or similar backend framework
• SQL/PostgreSQL or similar database framework
• Ability to design and implement: HTTP/REST APIs; DB schemas + migrations (PostgreSQL strongly preferred); server routing and session management/auth
• Strong product intuition: eye for workflow correctness, UX clarity, and UI polish
• Ability to reverse engineer workflows from observation and documentation
• Self‑directed execution with clear communication and structured reasoning
