Job Title: AI Engineer
Company Description: Electric Twin - Atomico-backed AI startup creating synthetic audiences
Job Description:
You will join the Science team to bridge the gap between AI research and production engineering. By designing cognitive architectures and memory systems for LLM-driven agents, you will help build a platform that predicts human behavior with 95% accuracy, enabling global brands to conduct deep market research in seconds rather than weeks.
Location: London, UK
Why this role is remarkable:
Work at the frontier of behavioral simulation with a platform that delivers insights 10,000x faster than traditional research, validated by research from the London School of Economics.
Join a high-caliber team founded by the former Chief Adviser on Digital to the UK Prime Minister and backed by $14M from top-tier investors including Atomico, LocalGlobe, and Marc Andreessen.
Direct impact on a product used by giants like News UK and Lebara, moving beyond static data to create dynamic, reasoning digital populations.
What you will do:
Design and implement cognitive systems that provide AI agents with consistent personalities, reasoning capabilities, and advanced memory using RAG and chain-of-thought prompting.
Conduct systematic experiments to validate synthetic agent behavior against real-world data, iterating on model architectures based on empirical performance.
Build the scalable backend infrastructure and sophisticated prompting strategies required to deploy multi-agent simulations in enterprise production environments.
The ideal candidate:
Possesses over 7 years of technical experience with at least 1 year of hands-on expertise building complex applications with Large Language Models and agentic workflows.
Demonstrates strong proficiency in Python and backend frameworks like FastAPI or Django, with a solid understanding of distributed systems and scalable architectures.
Holds a degree in a quantitative field (CS, Math, Physics, or AI) and thrives in fast-paced environments where research-driven development meets pragmatic engineering.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
