Job description

Senior Product Engineer – Python / React | £650/day Outside IR35

Up to £650/day | Outside IR35 | 6 Months | Shoreditch, London

I’m working with an exciting early-stage HealthTech business that is building a highly ambitious consumer healthcare product from the ground up.

They have an exceptionally experienced founding team with a strong track record of building, scaling and exiting successful technology businesses, and are now growing the engineering team at a key stage of the company's journey.

They’re looking for an experienced Product Engineer who wants genuine ownership - working closely with the founders and engineering team to take problems from initial idea through to production and customer feedback.

This isn't a ticket-driven engineering role. They need someone who enjoys building, shipping and making product decisions.

Key experience:

• React and comfortable working across the full stack
• SQL / relational databases
• AWS or GCP
• Genuine 0→1 product experience
• Strong track record of personally building and shipping products
• Strong product judgement and ownership
• 5+ years' software engineering experience

Experience within HealthTech, FinTech or another regulated environment would be particularly valuable, alongside experience building consumer-facing products or joining an early-stage engineering team.

Rate:

Up to £650/day

Duration:

Initial 6 months

Location:

Shoreditch, London – 5 days onsite

The onsite environment is very intentional. You’ll be working directly alongside an experienced founding team during a formative stage of the product and business.
