Company mission
To improve our understanding of the world.
Role
Who you are
- You’ve built and shipped production software that real users rely on
- You’re comfortable working with ambiguous problems and incomplete requirements
- You take ownership of features or systems end-to-end, from idea to iteration
- You can explain technical decisions and trade-offs clearly
- You care about quality, but you bias toward shipping and learning
- You’re happy working in a small, fast-moving team with high accountability
Desirable
- Experience working across both frontend and backend
- Experience designing or evolving backend services or APIs
- Interest in system design, performance, or reliability as products scale
- Experience working in an early-stage or fast-growing company
- Comfort working on products that involve data, modelling, or AI-adjacent systems
What the job involves
- Building and shipping features that real users rely on
- Turning vague or uncomfortable problems into working software
- Owning parts of the product and system end-to-end, from idea through to iteration
- Working across frontend and backend, leaning into your strengths
- Improving code quality, performance, and structure as part of everyday delivery — not as a separate “cleanup” phase
- Making pragmatic trade-offs between speed, clarity, and long-term system health
- Collaborating closely with product, design, and founders to decide what to build, not just how
Application process
- Stage 1: Intro & engineering conversation (60 mins, video call): An introduction to Electric Twin and the role, followed by a discussion of your background and a real engineering problem you’ve worked on. We’re interested in how you think, make decisions, and reflect on real work
- Stage 2: Code review & design session (90 mins, in person): A collaborative session reviewing a small codebase and working through a system design problem together. We’re interested in your thinking, trade-offs, and approach — not getting to a “perfect” answer
- Stage 3: Team & founder conversations (in person): Time with the wider team and founders to go deeper on ways of working, mutual fit, and any remaining questions on both sides

Our take
Electric Twin is a company utilising large language models to simulate human behaviour. Through its LLM models, users can create synthetic populations that represent their target markets or research demographics in order to investigate outcomes in near real-time and make more informed decisions.
The company supplies a range of investigative tools; from qualitative polling and quantitative analysis, to simulated focus groups or even one-on-one discussions. It also enables ideas to be continuously refined through strong feedback, ensuring that strategy can always be backed by the latest data.
With such a unique proposition, Electric Twin stands out as one to watch in the rapidly developing generative AI sector. It is currently working to build out its team and, if its models are able to deliver the value suggested, there will surely be no shortage of success in its future.
