Senior Research Engineer

Flow Traders is looking for a Senior Research Engineer to join us in our London office. This is a unique opportunity to join a leading proprietary trading firm with an entrepreneurial and innovative culture at the heart of its business. We value quick‑witted, creative minds and challenge them to make full use of their capacities.

As a Senior Research Engineer, you will be responsible for helping to lead the development of our trading model research framework and using it to conduct research to develop models for trading in production. You'll expand the framework to become the global standard way of training, consuming, combining, and transforming any data source in a data‑driven systematic way. You will then partner with Quantitative Researchers to build the trading models themselves.

What you will do:

• Help to lead the development and global rollout of our research framework for defining and training models through various optimization procedures (supervised learning, backtesting etc.), as well as its integration with our platform for deploying and running those models in production.
• Partner with Quantitative Researchers to conduct research: test hypotheses and tune/develop data‑driven systematic trading strategies and alpha signals.

What you need to succeed:

• Advanced degree (Master's or PhD) in Machine Learning, Statistics, Physics, Computer Science or similar.
• 8+ years of hands‑on experience in MLOps, Research Engineering, or ML Research.
• A strong background in mathematics and statistics.
• Strong proficiency in programming languages such as Python, with experience in libraries like numpy, pytorch, polars, pandas, and ray.
• Demonstrated experience in designing and implementing end‑to‑end machine learning pipelines, including data preprocessing, model training, deployment, and monitoring.
• Understanding of and experience with modern software development practices and tools (e.g., Agile, version control, automated testing, CI/CD, observability).
• Understanding of cloud platforms (e.g., AWS, Azure, GCP) and containerization technologies (e.g., Docker, Kubernetes).

What We Offer:

• Attractive Compensation: Remuneration package comprised of a base salary and a discretionary variable component.
• Continuous Learning and Development: Dedicated academy with endless personal and functional development opportunities.
• Exceptional Events and Social Activities: Annual company trip, holiday parties, family and sports events.

• Global Rotations Opportunities: Opportunities to work in different locations to support personal growth within the company and develop your career.
• Great Global Locations: Vibrant working environments, furnished with lounges, bars, gaming areas and offering lunches and coffee.
• Wellness and Healthy Culture: Active lifestyle promoted by offering sports, healthy food and wellbeing programs.
• Working with Great Minds: Informal working environment, with a focus on direct and open communication, entrepreneurial spirit and a driven atmosphere.
