You will build critical decision infrastructure that uses AI-powered synthetic audiences to simulate human behavior. Working directly with hands-on founders, you'll evolve a platform that replaces guesswork with evidence-based modeling. This role requires an execution-focused engineer who can navigate ambiguity and bridge the gap between complex AI orchestration and intuitive product design.

Product / Software Engineer at Electric Twin
Most organizations make massive decisions based on gut feel. Join a London-based team backed by over £10M in funding to build the software that changes that. Led by founders with deep experience at the highest levels of government data and mass testing, this startup uses AI-powered synthetic audiences to simulate human responses in real-time. If you are a product-minded engineer who loves Python, React, and shipping features that solve complex orchestration problems without the hype, this is a rare chance to shape a platform while it's still malleable.
