Job Description
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.

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
