Job description
We're working with an early-stage, mission-led business in the financial wellbeing space, looking to hire a Founding Engineer to play a pivotal role in shaping both the product and the technical direction of the company. This is a high-impact, hands-on role with a clear pathway into Head of Engineering, offering the opportunity to work directly with the founders to build and evolve an AI-native product from the ground up. If you're at a point in your career where you want more ownership, influence, and long-term upside, this is a rare opportunity to step into a true founding-level position. About the Product The platform focuses on improving how people think, act and feel about money, combining:
- Open banking integrations
- Behavioural change principles
- Gamified, Duolingo-style learning experiences
- Financial wellbeing and education
The next phase of growth is centred around embedding AI at the core of the product experience, not as an add-on, but as a fundamental layer driving personalisation, engagement, and insight. The Role You will take ownership of the core product experience, with an immediate focus on the mobile application, while contributing to the broader technical architecture and long-term platform strategy. This is not a traditional "hands-off" leadership role - you will remain deeply hands-on, operating as a builder, architect, and strategic partner to the founders. What You'll Be Doing Product Engineering
- Lead development of the mobile application

- Embed AI meaningfully into the product experience
Explore use cases across:
- Personalisation
- Behavioural insights
- User engagement
- Leverage modern AI tooling to accelerate development and improve output
Technical Strategy
- Help define and evolve system architecture
Make key decisions across:
- Mobile stack
- Backend integrations
- Data and AI infrastructure
- Balance speed vs scalability in an early-stage environment
Commercial & Product Input
- Contribute to product direction and prioritisation
Work closely with founders on:
- Product-market fit
- Feature roadmap
- Partner integrations (e.g. HR platforms, B2B2C distribution)
Future Leadership
- Progress into Head of Engineering (9-18 months)
- Build and scale the engineering function
- Define engineering culture, standards, and processes
- Mentor and develop future hires
