Lead Java Engineer; Risk

ROLE PROFILE:

CDSClear is responsible for clearing Credit Default Swap (CDS) indices, single names and options across European, US and Asian markets.

Risk is a core capability of the service, supporting intraday and overnight batch margin calculations, member‑facing what‑if simulations, and pricing analytics.

This contract role sits within CDSClear Risk Technology, focused on the Java‑based risk platform and risk engine that delivers quantitative margin models at scale in a highly regulated environment.

ROLE

SUMMARY:

The role is suited to experienced engineers who have worked on risk, pricing or analytics platforms in an investment bank, CCP or similar financial services environment. You will work on systems that sit at the core of the clearing service, where correctness, performance, resilience and operational control are essential

You will help build and implement the platform components and execution patterns that allow quantitative risk models to run reliably in production, contributing directly to both system behaviour and overall platform direction.

This is a Lead Individual Contributor (IC) role: highly hands‑on, with significant influence over design and technical direction, and an expectation of strong ownership across the end‑to‑end lifecycle of the systems you work on.

Key Responsibilities Act as a Lead Java Engineer within the CDSClear Risk Development team, contributing across all stages of the SDLCDesign, implement and evolve core risk-engine components supporting intraday and overnight batch margin calculations

Contribute to the implementation of quantitative risk models by translating analytic requirements into production‑grade system behaviour

Provide technical leadership across Risk calculation orchestration

Integration of market data, trade data, reference data and model parameters

Performance, scalability, determinism and failure handling

Own delivery of business requirements through development, testing and controlled production release

Drive evolution of the risk platform, combining incremental improvements with more substantial architectural step‑changes, while maintaining a strong focus on delivery, quality and maintainability

Collaborate with infrastructure, security and Dev Ops teams to deliver end-to-end solutions

Participate in third-line system support, including out-of-hours rota where required

Candidate Profile / Key Skills Essential Strong  server‑side Java engineering experience (Java 11+; Java 17+ preferred) using Spring / Spring Boot Ability to understand quantitative models and make informed implementation trade‑offs when integrating them into production systems

Practical experience contributing to or shaping a risk‑engine architecture capable of executing computationally intensive models at scale

Strong understanding of enterprise platform concerns, including:

Performance and scalability

Resilience and recovery

Auditability, controls and operational readiness

Comfortable working in a regulated / controlled environment with disciplined SDLC and production change processes

Clear communicator with the ability to influence technical decisions through expertise and collaboration

Ownership mindset, with a drive to improve quality, robustness and long‑term maintainability of the platform

An interest in modern engineering productivity approaches, including the efficient use of AI‑assisted tooling (e.g. Copilot‑style tools) to aid codebase comprehension, documentation & delivery — applied appropriately within a controlled environment

Technical Environment (Indicative)
Java, Spring Boot, Maven, IntelliJMessaging: JMS, ActiveMQ / IBM MQ, Kafka Linux-based server environments CI/CD:
Git Lab, JUnit, Mockito, Cucumber Git-based source control

Preferred / Nice to Have Experience working…
