We're looking for a Senior Trading Platform Engineer (Full Stack) to join an established trading platform development programme for a large enterprise client. The platform has been live in production for over 7 years, with most of the core team having worked on it for close to 5 years on average — a reflection of the stability, quality, and long-term nature of this engagement.

The system is production-critical and actively evolving, with a strong focus on performance, reliability, and maintainability. While Applied Blockchain is well known for distributed ledger and cryptography work, this role is focused on a non-blockchain trading system built using modern TypeScript-based technologies. The role is full stack in nature, though with a slightly stronger emphasis on the frontend (React/TypeScript).

You'll be joining a highly experienced team of senior engineers and QA developers, where autonomy, technical ownership, and thoughtful decision-making are expected.

What You'll Be Doing

  • Designing, building, and maintaining features across the full stack of an internal trading platform
  • Working primarily with:
    • TypeScript (Node.js & React)
    • Monorepo tooling, GitHub, GitHub Actions
    • Jest, Playwright
    • Redis, MS SQL, WebSockets
    • Docker, Kubernetes
    • Observability tooling (Grafana, Prometheus, SonarQube)
  • Taking end-to-end ownership of features from design through to production
  • Collaborating closely with platform / DevOps engineers on build pipelines, observability, and operational concerns
  • Communicating directly with the client to clarify requirements and propose solutions
  • Contributing to and improving automated testing practices
  • Participating in peer code reviews and helping maintain high engineering standards across the team
  • Using LLM/AI enabled development tools and techniques (with access to the latest OpenAI/Anthropic/etc. models) as part of day-to-day development

Requirements

  • 8+ years of professional software development experience
  • 3+ years of hands-on experience with TypeScript, including Node.js and React
  • Strong experience building and maintaining production systems
  • Comfortable working in a senior, autonomous engineering team
  • Strong communication skills and fluency in English
  • Hybrid work arrangement (Waterloo, London)

Nice to have

  • Experience with functional programming concepts or languages (e.g. OCaml, Haskell)
  • Prior experience in trading, finance, or other real-time systems
  • Solid understanding of DevOps and operational concerns (logging, metrics, automation)
  • London-based
  • Willingness to travel to company/client events

Benefits

  • 5 days/per year for training
  • £1,000 annual allowance for training (up to 50% of this value can be used for you to buy workstation equipment to work from home)
  • In-person fun team events/team buildings every 3 months
  • Company equipment and onboarding kit
  • Annual bonus (dependent on company and personal performance)
  • Stock option plan
  • Birthday off
  • Generous employee referral programme
