Full Stack Engineer
London, UK
Are you a Full-Stack Engineer who thrives on building things from scratch and wants to shape a new platform for agentic AI economics? Want to be engineer #3?
About the Mission
Build the go-to intelligence platform for tracking AI agent costs, margins, and predicting future burn. You'll architect, own, and deliver real-time data streaming, analytics, and powerful APIs for dashboards and integration — turning millions of metrics into actionable insights for the world's fastest-moving AI companies.
What You’ll Build
High-throughput, low-latency event pipelines using modern streaming frameworks.
Scalable databases and attribution engines (Postgres, ClickHouse) for cost/revenue mapping.
APIs and dashboard integrations in TypeScript and Python.
Machine learning infrastructure for prediction and anomaly detection.
End-to-end reliability, observability, and cloud scalability (AWS, GCP, Docker, Kubernetes).
The Opportunity
Full technical ownership — drive architecture, standards, and build at company-defining scale.
Work in a collaborative London HQ office (4 days/week) with two experienced founders and front-end leaning full-stack hire #1.
Salary £100k + generous equity, private health care & pension.
Your Background
3+ years building distributed, high-throughput backend and full stack systems.
Expert in data streaming, event-driven design, and modern databases.
Fluent in Python, TypeScript or Go; advanced API development (REST/GraphQL).
Strong knowledge of security and cloud infra; frontend experience (React) major plus.
Startup energy: curious, proactive, communicative.
