Job Title

Founding Engineer

Company Description

Aspire Project is a pre-seed London startup building an AI-enabled financial planning and career coaching platform for young people, backed by an advisory network of leaders from Barclays, HSBC, and Y Combinator.

Job Description

As Founding Engineer at Aspire Project, you will lead the technical development of a mobile-first AI platform helping young people navigate financial planning. Transitioning from part-time to full-time, you will own the entire stack—React Native, Python, and Supabase—while working directly with the founder to scale a product already endorsed by industry leaders.

Location

London, UK

Why this role is remarkable

True founding-level ownership with meaningful equity, starting part-time and scaling into a full-time leadership position as the company grows.

Join a mission-driven startup with high-level industry backing, including endorsements from the former Group CEO of HSBC and recognition from The Times.

Complete technical autonomy over a live, mobile-first product built on a modern stack including React Native, TypeScript, Python, and Supabase.

What You Will Do

Architect and build end-to-end features across the mobile application and backend infrastructure, ensuring a seamless user experience for the next generation.

Collaborate directly with the founder to define the technical roadmap and make critical architectural decisions that shape the future of the platform.

Manage the deployment and scaling of the product using Railway and Supabase while maintaining high-quality code and rapid shipping cycles.

The ideal candidate

Previous experience as a Founding Engineer or Senior Software Engineer at a VC-backed or accelerator-backed startup (e.g., YC, EF, Antler, or Techstars).

Full-stack proficiency with React Native for mobile development and Python for backend logic, plus experience managing cloud infrastructure and databases.

A mission-driven builder who thrives in high-autonomy environments and is comfortable transitioning from a part-time founding role to a full-time lead.
