Founding Product Engineer (Full-Stack / Mobile)

Founding Product Engineer (Full-Stack / Mobile) at Aituki[Co-founder Opportunity | Remote UK]

Please note: This is an unpaid, co-founder level role.

About Aituki:

At Aituki, we are creating a new category of proactive wellness called Bio-Signal Intelligence (BSI). We are an early-stage, pre-seed startup building an AI-powered coach to provide users with holistic and personalized health insights. We have a complete Figma prototype and a clear technical strategy, and our foundational backend is already in place.

The Role:

We are seeking a talented and product-focused engineer to join our founding team. You will be responsible for building our application on top of our existing backend foundation, translating our vision and designs into a beautiful, functional, and scalable product. You will work in direct collaboration with our AI Lead and our designer.

This is a hands-on role with ownership over the entire user-facing platform.

What You'll Do:

• Take ownership of building our user-facing application, turning our detailed Figma designs into a seamless mobile or web experience.
• Collaborate with our AI Lead to build upon the existing FastAPI backend foundation, developing new features and ensuring scalability.
• Implement a headless CMS to manage and serve our expert-written wellness content for features like the Learning Page.
• Integrate the front-end with our internal AI service APIs to fetch and display dynamic, personalized insights for users.
• Manage the full product lifecycle, from development and testing to deployment and maintenance on a cloud platform.
• Work closely with the entire founding team to define product priorities and the technical roadmap.

Who You Are:

• An experienced product-focused developer with a portfolio showcasing applications you have built from scratch.
• Proficient in modern front-end frameworks (e.g., React Native, Swift, Next.js) and backend development (ideally with Python experience to collaborate on the FastAPI codebase).
• Strong experience with building and consuming REST APIs, working with databases (PostgreSQL), and deploying applications in a cloud environment.

The Opportunity:

This is a co-founder level role for an engineer who is passionate about building a product from its earliest days and having a foundational impact. The position is unpaid until our seed funding is secured, at which point a competitive, market-rate salary will be implemented.
