Electric Twin
London, UK | Full-time
hn · London, UK
Jose is an exceptionally strong match for either role at Electric Twin. For the Product Engineer position, he has direct mastery of the exact tech stack (React, Next.js, Python, FastAPI, SQL, GCP) and has shipped multiple production AI products end-to-end. For the Research Engineer role, his M.S. in AI with deep learning focus, combined with hands-on LLM agent architecture experience (LangGraph, RAG, model fine-tuning), and scientific rigor demonstrated through his analytics and simulation work, makes him competitive. His founding engineer background shows senior-level ownership and ability to solve ambiguous problems at the intersection of behavior modeling and product.
Hook: Your founding engineer background shipping LLM agents and real-time AI products across multiple platforms directly mirrors Electric Twin's need to build AI behavior simulation infrastructure at scale.
Missing: Domain expertise in synthetic population modeling or behavioral simulation, Prior experience with GCP specifically (though he has AWS/cloud infrastructure depth), Published research in LLM-based agent evaluation or validation methodologies

Electric Twin | London, UK | Full-time | Hybrid (4 days/week in office) Electric Twin builds science-based synthetic populations — LLM-driven AI agents that simulate human behaviour, so companies and governments can test ideas and explore uncertainty before they commit. We've just entered a major growth phase: new funding, a growing customer base, and a platform still taking shape. We're hiring across engineering and science: Research Engineer (Science Team) — Pioneer the application of LLMs to model human behaviour: design cognitive and LLM-based architectures, figure out how to evaluate agent behaviour in ambiguous scenarios, and build experimental methods to validate simulations. MS/PhD or equivalent practical experience; strong Python and ML frameworks; rigorous scientific mindset. Feel free to DM: yoanna.peneva@electrictwin.com Product Engineer (Engineering Team) — Own problems end-to-end where behaviour, prediction, and UX meet. React, Next.js, Python, FastAPI, SQL, GCP. Your choice of Claude, Cursor, or Codex. Multiple roles across all levels. Feel free to DM: harry.smith@electrictwin.com Small, senior team. Benefits include pension matching (4–8%), £1,000 annual L&D budget, Cycle to Work, and the kit you need. Apply: https://jobs.lever.co/electric-twin
