Founding Full stack Engineer

We’re working with a startup that is transforming how companies hire across tech, consulting, finance, and other high-growth industries. Their platform replaces outdated assessments with AI-driven, immersive simulations — including live case interviews, technical challenges, and real-time role play. The goal is to evaluate candidates on what actually matters: problem-solving, analytical thinking, and real-world performance.

As a Full-Stack Engineer, you’ll take ownership of building and scaling a highly interactive, AI-powered platform. You’ll be part of the founding team working across the stack and contributing to key decisions around architecture, product, and technical direction.

What You’ll Be Doing

• Designing and building full-stack features across React, TypeScript, and Python
• Developing scalable backend systems and APIs
• Working with AWS cloud infrastructure (or similar)
• Contributing to AI/LLM-driven workflows and product features
• Collaborating closely with founders on product and technical strategy
• Owning key parts of the system architecture and engineering roadmap

What We’re Looking For

• Strong full-stack development experience across modern web technologies
• Proven ability to deliver high-quality products end-to-end
• Experience in startups 0-1
• Comfortable owning systems and making architectural decisions
• Tech lead experience is a plus

• Based in London (Hybrid)
• No sponsorship available

This is a great opportunity for a product focused engineer who enjoys building from the ground up. If you're interested, apply today!
