Seed-stage intelligence platform for external risk management.

As the first technical hire, you will build a complex risk-monitoring platform from the ground up. You will architect an intelligence engine that synthesizes signals from open-source feeds and licensed data into a real-time client interface. Working directly with the founders, you will define the technical roadmap and drive the core product vision.

Location: London, UK

Why this role is remarkable:

  • Join as the first full-time engineer and shape the entire technical foundation of a high-stakes intelligence platform.
  • Solve complex data engineering challenges involving real-time signal processing, AI synthesis layers, and sophisticated entity mapping.
  • Work directly with founders in a fast-paced seed-stage environment with significant equity ownership and influence over product strategy.

What You Will Do:

  • Architect and build the core Risk Monitor platform using Node.js, Python, and React, transitioning from prototype to production.
  • Develop an AI synthesis layer that processes massive volumes of incoming data signals to generate actionable client briefs.
  • Design and implement the database architecture using Supabase to manage complex entity relationships and alert thresholds.

The Ideal Candidate:

  • Proven experience building data-intensive or intelligence-adjacent products from scratch, ideally within early-stage startups.
  • Full-stack proficiency with the ability to own both a React frontend and a backend infrastructure powered by Node.js and Python.
  • A product-minded engineer who thrives on ambiguity and is excited to tackle the challenges of a pre-revenue, high-growth environment.
