Job description

This is a job that we are recruiting for on behalf of one of our customers.

To apply, speak to Jack. He's an AI agent that sends you unmissable jobs and then helps you ace the interview. He'll make sure you are considered for this role and help you find others if you ask.

We are hiring for a company that is seeking a visionary Founding Engineer to be the first technical hire at a rapidly growing, venture-backed AI content platform.

This is a unique opportunity to own the entire technical landscape, from critical architecture decisions to shipping deadlines, and establish the scalable foundations for our next phase of growth. You'll work closely with non-technical co-founders, guiding strategic product and technology direction, with an option to step into a Co-Founder role based on experience and mutual fit.

What We're Looking For:

• 5+ years of full-stack engineering experience, with a strong backend emphasis, proven in building scalable, robust systems from the ground up.
• Demonstrated ability to transform an early-stage MVP into a production-ready, client-onboarding platform, addressing critical infrastructure needs (security, compliance).
• Genuine 0-to-1 founding mindset: high agency, comfort with ambiguity, and the strategic leadership to guide non-technical founders on all technical decisions.
• Proficiency with modern web technologies (e.g., React, TypeScript, cloud infrastructure) and a strong architectural judgment to define and implement a flexible, future-proof stack.
• London-based with existing legal right to work in the UK, without requiring visa sponsorship.
