Senior Full Stack Engineer

Job description

Join an elite engineering team building a high‑performance trading platform.

Are you a seasoned Full‑Stack Engineer who thrives in highly technical, autonomous environments?

Do you love designing reliable, long‑lived systems and solving complex performance challenges?

A leading engineering organisation is hiring a Senior Full‑Stack Engineer to join an established trading platform development programme for a major enterprise client.

Although the wider business is recognised for distributed ledger and advanced cryptography work, this role focuses on a non‑blockchain, production‑critical trading platform built with modern TypeScript technologies.

• Designing, building, and maintaining features for an internal trading platform
• Working with:
• TypeScript, Node.js, React, Redis, MS SQL, WebSockets
• Docker, Kubernetes, GitHub Actions, Jest, Playwright
• Grafana, Prometheus, SonarQube
• Taking end‑to‑end responsibility from design → production
• Collaborating closely with platform/DevOps engineers
• Enhancing observability, automation, and operational excellence
• Communicating directly with the client to clarify requirements
• Using LLM/AI development tools day‑to‑day
• Participating in code reviews and elevating engineering standards

Requirements

You're a great fit if you bring:

• 8+ years of professional software development experience
• 3+ years hands‑on with TypeScript (Node.js & React)
• Strong experience maintaining production systems
• Comfortable operating autonomously in a senior engineering environment
• Excellent communication skills & fluent English
• Based in London (hybrid, Waterloo)
• Experience with functional programming (OCaml, Haskell)
• Background in trading, finance, or other real‑time systems
• Strong DevOps understanding (logging, metrics, automation)
• Willingness to travel for team/client events

Want to join a senior engineering team solving real‑world, high‑performance challenges?
