Senior Full Stack Engineer | TypeScript, React & NestJS | Real-Time Cyber Exposure Platform

The Role
You’ll join a senior, client-facing product team building real-time applications that show organisations exactly how they can be breached.

In this role, you will work across the full stack, shaping both backend services and complex, data-heavy frontend experiences. You’ll partner closely with product and design to turn threat intelligence and attacker telemetry into intuitive, high-impact tooling used by some of the world’s most security-conscious organisations.

This is a hands-on senior role where you’ll influence architecture, raise engineering standards, and help scale a platform operating at real-world attacker speed.

What They’re Looking For (Non-Negotiables)
You’ll bring strong full stack experience and be comfortable owning problems end-to-end. Specifically, you will have:
  • 5 years building production-grade SaaS products across the full stack
  • TypeScript development across backend and frontend systems
  • NestJS backend engineering, including REST APIs and GraphQL services
  • React and Next.js development for complex, data-driven applications
  • Experience building dashboards and analytical UIs used by technical users
  • Relational database experience (MySQL) plus exposure to NoSQL systems
  • Strong debugging, performance optimisation, and scalability instincts
  • Experience working in fast-moving environments where priorities evolve quickly

What You’ll Work With
You’ll be hands-on with a modern, TypeScript-first stack, including:
  • TypeScript backend services with NestJS
  • REST APIs and GraphQL
  • Sequelize ORM
  • React and Next.js frontend applications
  • Chakra UI component systems
  • React Query for data fetching
  • MySQL and NoSQL databases
  • Kafka for event-driven workflows
  • Figma collaboration for translating complex designs into production code

Nice to Haves
It’s a bonus (but not essential) if you’ve worked with:
  • AWS cloud environments
  • Kubernetes-based infrastructure
  • Workflow engines such as XState or Argo Workflows
  • Cybersecurity, threat intelligence, or offensive security products
  • Networking or infrastructure-level systems

You’ll be joining a high-growth, research-driven engineering team building technology designed to operate at attacker pace, not quarterly release cycles.

You’ll work on:
  • Real-time exposure and attack-path visualisation products
  • Client-facing platforms used directly by security teams
  • Highly scalable systems that ingest, process, and present live attacker telemetry
  • A product shaped by original vulnerability research and real-world red-teaming

You’ll have genuine influence over how the platform evolves, how teams build, and how engineering excellence is maintained as the company scales.
