Job Description

You9ll join as an early full stack engineer, shaping both the product and the foundations it9s built on.

The work sits around the models, not inside them. You9ll build the platform, workflows, and interfaces that make AI usable in real-world environments. That means designing systems that are reliable, observable, and genuinely pleasant to work with, both for users and other engineers.

There9s no separation between building and shipping here. You9ll take ideas from whiteboard to production, owning the outcome end to end. The bar is high, but so is the autonomy.

You9ll spend time designing clean API contracts, modelling data properly, and building frontends that don9t fight you six months later. Velocity matters, but not at the expense of quality.

Your focus will include:

• Designing and building backend systems in Python using FastAPI, from API design through to database schema and infrastructure
• Creating high-quality frontend experiences in TypeScript and React, with strong typing and clean component architecture
• Building shared libraries, internal tooling, and component systems that improve how the whole team ships
• Owning problems end to end, from shaping ambiguous requirements through to production deployment
• Developing integrations, connectors, and data pipelines that tie the platform into external systems

You9ll also have real input into how the product evolves, working closely with design and product to understand how customers use what you build.

This is greenfield work. The decisions you make now will compound over time.

They9re looking for engineers who care about how things are built, not just that they work.

• You enjoy writing Python and TypeScript to a high standard, with strong typing and clear structure
• You think carefully about data models and take pride in getting schema design right
• You9ve built libraries, SDKs, or internal tooling that improved developer experience
• You9re comfortable owning problems end to end, even with ambiguity
• You have good product instinct and care about how things feel to use

Experience-wise, around 3+ years is a useful guide, but what matters more is how you think and build.

You9ll join a small, high-calibre team where you can influence tooling, patterns, and technical direction from day one.

Compensation: Up to $250,000 base + equity
Location: New York (in-person)

If building foundational systems properly, with real ownership, sounds like your kind of environment, it9s worth a conversation.
