The Role

As a Full‑Stack Software Engineer on our Strategy Platform Engineering team, you will build and evolve the trading systems and the tooling that enable our strategies to scale. Based in London, you’ll join a specialised group within Securities Engineering with a dual mandate: advancing core systems, such as trading infrastructure and large‑scale data pipelines, as well as delivering the web applications that put those capabilities in the hands of traders, production operations, and researchers.

Your team owns the end‑to‑end delivery of internal web interfaces that power trader monitoring of our strategies and give production operations clear visibility into our machine‑learning pipelines and live trading system health. You will also improve the ergonomics of common developer workflows used to build trading strategies. This is an opportunity to work on mission-critical systems while also shaping how traders, operations, and research teams interact with them day to day. Engineers in this group are expected to work across the stack, contributing to frontend applications, trading infrastructure, and data and research pipelines. The role also offers the chance to evolve frontend and workflow tooling for the entire company, setting the standard for how web applications and internal tools are built at Voleon.

Responsibilities

• Own end‑to‑end delivery of internal web applications that power trader monitoring, production‑ops visibility, and research workflows.
• Contribute to the team’s existing areas of responsibility, including integration with new assets and markets, profiling and optimisation of distributed systems, and improving trading system resilience.
• Collaborate closely with researchers, traders, and operations staff to translate complex requirements into reliable engineering solutions.
• Own the reliability of what you ship, participating in incident reviews and driving preventive improvements across the stack.
• Collaborate closely with Senior Software Engineers and benefit from mentorship and coaching.

Requirements

• Bachelor’s degree in Computer Science or a related technical field (Graduating class of 2026 or equivalent).
• Strong programming fundamentals, with hands-on experience in at least one general-purpose language such as Python, Java, Go, or C/C++.
• Experience developing software in a Linux or Unix-like environment, with an emphasis on correctness, performance, and reliability.
• Familiarity with backend engineering concepts, such as APIs, databases, concurrency, or distributed systems, through coursework, internships, or projects.
• Demonstrated ability to design, implement, and test a backend or service-oriented application given design requirements.
• Strong problem-solving skills and attention to detail.
• Excellent written and verbal communication skills, with the ability to collaborate effectively across teams.

Preferred Qualifications

• Exposure to web technologies, such as JavaScript or TypeScript, and modern frontend frameworks (e.g., React), through projects or internships.
• Experience building or contributing to internal tools, dashboards, or developer-facing systems (e.g., observability, monitoring, analytics).
• Familiarity with asynchronous or concurrent programming models.
• Experience with containerization or deployment tooling, such as Docker or Kubernetes.
• Familiarity with modern build and tooling systems, such as Bazel.
• Experience working in fast-moving environments, including internships, research labs, or student-led engineering teams.
