Machine Learning Engineer

This is a remote position.

We’re seeking a highly skilled Machine Learning Engineer to join a dynamic team at a leading quantitative trading firm known for leveraging technology to drive global trading strategies. This role offers a unique opportunity to work at the intersection of cutting-edge machine learning research and high-performance trading systems.

As part of the ML team, you’ll be responsible for developing, deploying, and optimizing machine learning models that enhance decision-making across multiple asset classes. You will collaborate closely with researchers, data scientists, and software engineers to build robust, scalable ML infrastructure that supports rapid experimentation and production-level performance.

The ideal candidate combines a strong theoretical understanding of machine learning with hands-on experience in building end-to-end systems. You’ll apply your expertise in various ML techniques—ranging from deep learning and gradient-boosted trees to ensemble methods—to solve complex problems in a fast-paced, data-rich environment.

You will also focus on refining research workflows, improving model reproducibility, and ensuring that models integrate smoothly with trading infrastructure.


  • Design, build, and maintain scalable training and inference pipelines for ML models used in trading decisions

  • Collaborate across teams to translate research innovations into production-ready systems

  • Optimize algorithms and model architectures to maximize predictive accuracy and latency requirements

  • Contribute to the continuous improvement of tools and processes that accelerate ML research cycles

  • Analyze large, complex datasets to extract insights and support data-driven decision-making



Requirements

  • A strong background in machine learning, statistics, or a related quantitative field is essential.
  • Experience with ML frameworks such a PyTorch or Tensorflow
  • Proficiency in Python and/or C++ for high-performance computing is required.
  • Candidates should have a solid foundation in mathematics, including linear algebra, optimization, and probability theory.
  • Familiarity with building reproducible research pipelines and managing codebases collaboratively is important.
  • Comfort working in Linux environments and cloud or distributed computing platforms is expected.

10 AI Recruitment Agencies in the UK You Should Know (2025 Job‑Seeker Guide)

Generative‑AI hype has translated into real hiring: Lightcast recorded +57 % year‑on‑year growth in UK adverts mentioning “machine learning”, “LLM” or “gen‑AI” during Q1 2025. Yet supply still lags. Roughly 18,000 core AI professionals work in the UK, but monthly live vacancies hover around 1,400–1,600. That mismatch makes specialist recruiters invaluable—opening stealth vacancies, advising on salary bands and fast‑tracking interview loops. But many tech agencies sprinkle “AI” on their website without an active desk. To save you time, we vetted 50 + consultancies and kept only those with: A registered UK head office (verified via Companies House). A named AI/Machine‑Learning or Data practice.

AI Jobs Skills Radar 2026: Emerging Frameworks, Languages & Tools to Learn Now

As the UK’s AI sector accelerates towards a £1 trillion tech economy, the job landscape is rapidly evolving. Whether you’re an aspiring AI engineer, a machine learning specialist, or a data-driven software developer, staying ahead of the curve means more than just brushing up on Python. You’ll need to master a new generation of frameworks, languages, and tools shaping the future of artificial intelligence. Welcome to the AI Jobs Skills Radar 2026—your definitive guide to the emerging AI tech stack that employers will be looking for in the next 12–24 months. Updated annually for accuracy and relevance, this guide breaks down the top tools, frameworks, platforms, and programming languages powering the UK’s most in-demand AI careers.

How to Find Hidden AI Jobs in the UK Using Professional Bodies like BCS, IET & the Turing Society

Stop Scrolling Job Boards and Start Tapping the Real AI Market Every week a new headline announces millions of pounds flowing into artificial-intelligence research, defence initiatives, or health-tech pilots. Read the news and you could be forgiven for thinking that AI vacancies must be everywhere—just grab your laptop, open LinkedIn, and pick a role. Yet anyone who has hunted seriously for an AI job in the United Kingdom knows the truth is messier. A large percentage of worthwhile AI positions—especially specialist or senior posts—never appear on public boards. They emerge inside university–industry consortia, defence labs, NHS data-science teams, climate-tech start-ups, and venture studios. Most are filled through referral or conversation long before a recruiter drafts a formal advert. If you wait for a vacancy link, you are already at the back of the queue. The surest way to beat that dynamic is to embed yourself in the professional bodies and grassroots communities where the work is conceived. The UK has a dense network of such organisations: the Chartered Institute for IT (BCS); the Institution of Engineering and Technology (IET) with its Artificial Intelligence Technical Network; the Alan Turing Institute and its student-driven Turing Society; the Royal Statistical Society (RSS); the Institution of Mechanical Engineers (IMechE) and its Mechatronics, Informatics & Control Group; public-funding engines like UK Research and Innovation (UKRI); and an ecosystem of Slack channels and Meetup groups that trade genuine, timely intel. This article is a practical, step-by-step guide to using those networks. You will learn: Why professional bodies matter more than algorithmic job boards Exactly which special-interest groups (SIGs) and technical networks to join How to turn CPD events into informal interviews How to monitor grant databases so you hear about posts months before they exist Concrete scripts, portfolio tactics, and outreach rhythms that convert visibility into offers Follow the playbook and you move from passive applicant to insider—the colleague who hears about a role before it is written down.
