Founding CTO | Stealth AI Start-Up | London
Founding CTO required to join a stealth mode AI start-up building a next-generation platform for one of the world's largest and most operationally complex industries.
Led by experienced founders, the business is at an early stage with a clear vision, significant ambition, and the opportunity to build a genuine category-defining product from the ground up. The platform combines AI, automation, knowledge management, and compliance workflows to solve problems that have historically been difficult to address with traditional software.
This is a rare opportunity for an experienced technical leader who still enjoys building. You'll own technology strategy, architecture, AI systems, product development, and engineering execution from day one, helping shape both the platform and the company itself.
You are:
- An experienced software engineer with approximately 10 years of experience building and delivering complex software products
- A hands-on technical leader capable of owning architecture, product delivery, and engineering execution end-to-end
- Experienced building AI-powered applications and production-grade AI systems
- Strong in Retrieval-Augmented Generation (RAG), knowledge retrieval systems, vector databases, and LLM application development
- Comfortable operating in highly ambiguous, fast-moving start-up environments where priorities evolve quickly
- Motivated by ownership, autonomy, and the challenge of building something from first principles
Bonus points:
- Experience building compliance-focused RAG systems or AI products operating within regulated environments
- Experience within construction, construction technology, property technology, or adjacent industries
Why join:
- Become the founding technical leader of a stealth mode AI venture from the earliest stage
- Significant influence over technology, product, hiring, and long-term company strategy
- Meaningful equity participation alongside a highly committed founding team
- Build a modern AI-native platform from scratch without legacy technology constraints
- Work on challenging problems spanning AI, automation, compliance, workflow orchestration, and knowledge systems
- Recruit and build a world-class engineering function as the company scales
If you're a hands-on engineering leader who enjoys combining deep technical execution with company-building, and want to play a defining role in creating a venture from the ground up, I'd be interested in speaking with you.
