Senior Full-Stack Engineer — US-based

We're staffing engineers for a US consultancy partner delivering an AI development program for a large enterprise client. This isn't a greenfield project - several iterations are already built, and you'd be joining mid-flight, working across a real full stack (React/TypeScript + Python/FastAPI) alongside the client's architects to help shape a product whose requirements are still taking form. If you want ownership over features end-to-end rather than a ticket queue, this is that kind of role.

What we expect from you:

• Strong commercial experience with React + TypeScript (front end)
• Strong commercial experience with Python + FastAPI (back end)
• PostgreSQL
• Genuine full-stack capability - you're comfortable owning a feature end to end
• Located in the United States
• Available to start in October and commit through the end of the year
• Comfortable working in an environment where the spec is evolving

Your responsibilities will include:

• Work across the full stack - both front end and back end, not one or the other
• Pick up and extend an existing codebase
• Work directly with the client's solution and business architects, alongside the partner's development and architecture team
• Contribute to a product where requirements are still being defined - you'll be part of shaping them, not just implementing tickets

Nice to Have:

• Experience on AI/ML-adjacent products
• Background working with or inside large enterprise organisations
• Prior contract or consulting experience

What We Offer:

• Fully remote; no on-site requirement
• Laptop and system access provided by the end client (note: access provisioning takes a few weeks, so timelines are tight)
• This is a short-term contract engagement - paid vacation and sick leave are not included
• Please share your expected hourly rate when applying
