(Please note: Sponsorship is not available for this role)

A top-performing global hedge fund is seeking an experienced Software Engineer for a 12-month contract to help enhance and scale its mission-critical trading infrastructure. This is a high-impact opportunity to work on systems that power execution, automation, and analytics across global markets.

About the Role

You’ll join a core engineering team focused on building and maintaining high-performance services and tools that sit at the heart of a multi-strategy trading platform. From designing low-latency APIs to deploying cloud-native services, your work will directly influence the efficiency and stability of trading operations.

This is a hands-on role suited for engineers who excel in complex, fast-paced environments where clean design and system resilience are essential.

Key Responsibilities

• Design and implement backend services and RESTful APIs using C# (.NET Core/.NET 6+) and Python.
• Containerize and orchestrate applications using Kubernetes across hybrid cloud/on-prem environments.
• Build highly available, scalable, and observable systems designed for 24/7 operation.
• Integrate services with trading platforms, data pipelines, and control tooling in collaboration with quants and traders.
• Automate CI/CD pipelines and implement rigorous testing to support rapid, reliable deployments.

What We’re Looking For

• Solid engineering experience with C#/.NET and/or Python in production environments.
• Proficiency preferred with Kubernetes and containerization tools (Docker, Helm, Operators, etc.).
• Strong grasp of distributed systems, microservices, and service-oriented architecture.
• Experience building performant, testable systems in mission-critical environments.
• Familiarity with trading platforms or (front office) financial environments is a strong plus.
• Clear, concise communicator who can work independently and take ownership from day one.
• Degree in Computer Science, Engineering, or related field from a top-tier or Russell Group university.

The Opportunity

• 12-month contract with meaningful technical ownership and visibility.
• Up to £900/day, inside IR35.
• Collaborate with world-class engineers and technologists in systematic trading.
• Join a high-trust, high-impact team with autonomy, pace, and a deep engineering culture.
