Senior Machine Learning Engineer - Trading

Senior Machine Learning/Research Engineer

London (Old Street / Moorgate)

Up to £140,000 + bonus

About the Role

We are working with a leading quantitative technology firm that's working at the cross roads of machine learning research and high-performance trading. You'll join a highly skilled Research Engineering team, in a fast-moving, high-volume environment.

This role is all about taking cutting-edge ML research projects and moving them into production - building robust pipelines that allow models to trade with reliability and speed. You'll be hands-on with code (around 80% of your time), collaborating closely with ML scientists, and owning solutions from ingestion to deployment.

Key Responsibilities

  • Collaborate with ML scientists to ingest and process large-scale, high-frequency market data.
  • Build and maintain pipelines for training, backtesting, and deploying ML models into a live trading environment.
  • Ensure production systems are reliable, scalable, and optimised for ultra-low latency trading.
  • Take ownership of end-to-end solutions, from research to execution.

What We're Looking For

  • 5+ years' experience in high-level engineering roles.
  • Proven track record building ML research pipelines in complex technical environments.
  • Experience in Python (and ideally C++) plus Kubernetes, Ray, PyTorch, Terraform, and cloud platforms (AWS, GCP, or Azure).
  • Strong mathematical or statistical background.
  • Background in AI-driven industries such as AI drug discovery, AdTech, ML health-tech, research labs, or high-end finance.
  • Independent, self-driven engineers who can own delivery without hand-holding.

Interview Process

  1. Intro with hiring manager and recruiter.
  2. Take-home technical test.
  3. Technical interview discussing your solution.
  4. Onsite with their Amsterdam team.
