We’re partnered with a leading investment management firm investing in the build-out of its in-house trading and investment technology platforms. They are now looking for a Trading Systems Developer who can help design, build and evolve platform capability across the full FX and investment technology ecosystem. This is not a generic C# development role. It’s a trading systems build role, focused on developing platform capability from the ground up across the full FX trade lifecycle. They’re looking for someone who understands how an FX platform works end to end - from data ingestion, pricing and execution through to booking, positions, risk, P&L and downstream reporting. You’ll work closely with trading, investment, risk, operations and technology teams to build robust, scalable systems that support real trading and investment workflows. This is a strong opportunity for someone who wants real ownership across a trading platform, rather than being boxed into one small service, screen or isolated workflow.
Key responsibilities include:
- Design, build and enhance C#/.NET applications across FX trading, investment technology, risk, analytics and reporting.
- Help develop trading platform capability from the ground up, including core services, data flows, workflow tooling and business-facing applications.
- Work across the full FX trade lifecycle, from pricing and execution through to booking, position management, risk, P&L and downstream reporting.
- Understand how data moves through the platform — where it comes from, why it is needed, how it is transformed, who consumes it and where it ultimately ends up.
- Integrate market data, trade data, position data, reference data, pricing inputs and risk metrics into scalable, reliable systems.
- Build real-time tools, services and dashboards used by trading, investment and operational teams.
- Improve workflow automation, data quality, execution efficiency, platform resilience and operational transparency.
- Partner directly with traders, portfolio/investment teams, risk and operations stakeholders to turn complex trading and investment requirements into robust technical solutions.
- Contribute to architectural decisions around platform design, data modelling, integration patterns and long-term scalability.
Requirements:
- A Degree in Computer Science, Software Engineering, Mathematics, Financial Engineering, Physics, Engineering or a related quantitative discipline is highly desirable.
- 5+ years’ commercial C#/.NET development experience, ideally within financial markets, investment management, trading technology, FX, derivatives or a similarly data-intensive environment.
- Strong understanding of FX products, trading workflows and investment-data flows.
- Experience building or significantly enhancing trading systems, investment platforms, risk systems, analytics platforms or trade lifecycle applications.
- Ability to understand the full trade lifecycle, not just one isolated area of a platform.
- Strong understanding of how trading and investment data is ingested, enriched, validated, processed, stored, consumed and reported.
- Experience working with market data, trade data, position data, reference data, pricing inputs and/or risk metrics.
- Strong SQL and database experience, including working with complex datasets and performance-sensitive queries.
- Ability to work closely with business users including traders, portfolio/investment teams, risk, operations and technology stakeholders.
- Strong problem-solving skills, attention to detail and ability to build practical solutions in complex environments.
Useful experience:
- Azure or cloud infrastructure; CI/CD and DevOps practices.
- Real-time analytics, data pipelines or trade support systems.
- Pricing, execution, position management, portfolio analytics or risk platforms.
- Exposure to multi-asset environments, FX, fixed income, equities or derivatives.
- Experience contributing to platform architecture, greenfield builds or major system modernisation programmes.
