Software Engineer at Electric Twin — VC-backed AI Decision Infrastructure

Join a small, high-velocity team building AI-powered synthetic populations to transform how governments and enterprises make decisions. You will own features end-to-end, moving between product-focused flows and robust system architecture. This is a rare opportunity to shape a malleable platform alongside founders who led data strategy for the UK Prime Minister.

• Build and ship end-to-end features using React, Next.js, and Python/FastAPI that real users rely on for high-stakes decision-making.
• Architect and orchestrate AI components to ensure synthetic population outputs are reliable, explainable, and trustworthy for enterprise applications.
• Collaborate in a high-bandwidth environment, iterating rapidly on APIs and system boundaries while maintaining a balance between speed and long-term technical health.

• Proven experience building and shipping production-grade applications, with a strong bias for execution and the ability to turn vague problems into working code.
• Proficiency across the stack—ideally with React, Python, or SQL—and a deep interest in the engineering challenges of integrating AI into real-world workflows.
• A mindset that thrives in ambiguity, values technical momentum over perfect specifications, and enjoys working 4 days a week from a London-based office.

• Work directly with founders Ben Warner (former Chief Advisor to the PM) and Alex Cooper (former Director of Mass Testing) on mission-critical decision infrastructure.
• Impact a platform that has already raised £7M and is being used by major institutions to model complex human behavior through science-based synthetic populations.
• Enjoy high autonomy and ownership in a small team where technical judgment is prioritized over ceremony and your architectural decisions will define the product for years.
