Job Description: 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.
Location: London, UK.
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.
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.
The Ideal Candidate:
- 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.
