Software Engineer (£75k–£105k + Equity) at Electric Twin - VC-backed AI Decision Infrastructure

Company Description: Electric Twin - £7M raised post-seed startup

Job Description:
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.

Why this role is remarkable:

• 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.

What you will do:

• 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.

The ideal candidate:

• 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.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
