Machine Learning Platform Engineer (Research-Focused) | Technology-Driven Quantitative Trading Firm

Role Overview

We’re partnering with a top-tier, technology-led trading firm where machine learning plays a central role in decision-making and execution. This hire will sit within a highly specialised ML group, contributing to the design and evolution of the firm’s research and production ML ecosystem. This is a hands-on engineering role operating close to research. You’ll help build the systems, tooling, and infrastructure that enable rapid experimentation and efficient deployment of models - while also contributing to how machine learning is applied across a fast-moving, data-rich environment...

Key Responsibilities

• Design and develop infrastructure supporting model training, evaluation, and production deployment
• Improve research workflows to accelerate iteration speed and feedback loops for ML experimentation
• Build clean, scalable tooling and APIs that make ML systems intuitive and efficient to use
• Collaborate with researchers to translate theoretical models into robust, production-ready solutions
• Evaluate and apply a broad range of modelling techniques depending on the problem space
• Maintain high-quality, reproducible research codebases with strong usability and structure
• Contribute to architectural decisions shaping the firm’s ML platform and tooling ecosystem
• Stay close to emerging ML techniques, frameworks, and hardware developments, integrating where valuable

What You’ll Bring…

• 3-8 years’ experience in machine learning engineering, applied ML, or similar technical roles
• Strong academic or practical grounding in mathematics (e.g. optimisation, linear algebra, probability)
• Experience building ML systems end-to-end, from experimentation through to production deployment
• Hands-on experience with modern ML frameworks (e.g. PyTorch, JAX, TensorFlow or similar)
• Proven ability to structure and maintain clean, reliable, and reproducible research code
• Solid software engineering fundamentals, including system design and API development
• Genuine interest in state-of-the-art ML research and willingness to explore new techniques
• Ability to critically assess modelling approaches and choose appropriate methods for different problems
• Strong communication skills and ability to collaborate closely with researchers and engineers
