Build the systems that enable organizations to test major decisions against synthetic populations covering 155 countries. You will own complex features from conception to deployment, working across Python, FastAPI, and React to solve systems-scale problems. This role offers the chance to bridge AI research and robust product engineering in a fast-paced Soho-based startup.
Software Engineer at Electric Twin
Join an elite engineering team in Soho building a behavioral simulation platform that is revolutionizing how global organizations make decisions. Backed by Atomico, LocalGlobe, and Marc Andreessen, this startup uses digital twins of real populations to provide 95% accurate answers 10,000x faster than traditional methods. As an early engineer, you’ll escape the ticket queue to own complex systems end-to-end, working directly with founders to scale a platform already spanning 155 countries. If you are a Mid, Senior, or Principal engineer looking for high ownership and meaningful equity, this is the role for you.

Role overview
About the company
Electric Twin
Electric Twin builds science-based synthetic populations and tools for interacting with them, enabling companies and governments to predict human attitudes and behaviour with high accuracy. Their technology creates simulations of real-world populations for rapid and scalable insights. Electric Twin was founded by the former Chief Advisor to the Prime Minister on Digital and Data and the former Director of Mass Testing, aiming to solve the problems they faced in understanding human behaviour during the pandemic. The team includes experts with backgrounds in data strategy, government, and advanced AI product development.
What you'll do
What you will do
- Design and implement the services, data models, and APIs that make large-scale behavioral simulations reliable and reusable.
- Collaborate directly with data scientists and designers to turn validated research into robust, customer-facing product features.
- Take ownership of the entire development lifecycle, making critical trade-offs between speed and rigour to ship high-impact software.
Who you are
Who this is a fit for
- Proven track record of owning meaningful product areas end-to-end in a startup or high-growth engineering environment.
- Strong proficiency in modern software engineering practices, with experience or a willingness to master Python, FastAPI, and TypeScript.
- Exceptional judgment under uncertainty and a bias for shipping and iterating rather than waiting for perfect specifications.
Why this role
Why this role is remarkable
- Backed by top-tier investors including Atomico, LocalGlobe, and Marc Andreessen, with a founding team led by former UK government and military advisors.
- Rare opportunity to build a product that is 10,000x faster than traditional behavioral research methods with 95% accuracy.
- High-ownership culture with no ticket queues or bureaucratic layers, located in a collaborative Soho office with genuine work-life balance.
