Product Engineer at Architect

Join a high-performance team of five building the future of the web. As a generalist Product Engineer, you will ship features across the full stack to transform static websites into intelligent, real-time AI agents. You will work directly with the co-founders to create personalized, high-conversion experiences for every visitor.

• Ship end-to-end features across a modern stack including React, TypeScript, Node.js, and Temporal.io on GCP.
• Design and implement AI agent evaluations and integrations to ensure every generated website is unique and optimized for conversion.
• Take full ownership of outcomes, from architecting authentication systems to building complex frontend page experiences and reinforcement learning models.

• Proven track record as a product-focused generalist with deep expertise in TypeScript and service-oriented backend architectures.
• Obsessive about craft and the "beautiful piece of wood on the back," writing maintainable, high-quality code at a rapid startup pace.
• Strong independent thinker with an interest in AI agents, LLMs, or workflow orchestration tools like Temporal.io.

• Join as a founding-level engineer at a company defining a new category of living, breathing web experiences that adapt in real-time.
• Backed by £3.5M from top-tier investors including Project A, Concept Ventures, and Insiders Ventures to rebuild the fundamental architecture of the internet.
• Massive technical ownership and impact while working in an intense, high-craft, in-person environment in the heart of London.
