AMS is the world’s leading provider of Talent Acquisition and Management Services. Our Contingent Workforce Solutions (CWS) service partner with Deutsche Bank to support contingent recruitment processes.

On behalf of Deutsche Bank, we are looking for a Senior Java Engineer for a 6 month contract based in the bank’s office location office on a hybrid working model of 3 days per week in the office and 2 from home.

We are looking for a senior hands‑on Java engineer to support CPT’s migration from legacy trade data source platform to a strategic data flow. The role will focus on designing, building and hardening services that extract, parse, validate, enrich and distribute Deal, PV/Risk, static data into CPT platforms and downstream consumers and related reporting and control processes.

• Design, implement and maintain cloud-hosted Java services for bulk trade / PV / Risk extraction, JSON parsing to CPT dictionary, integration with upstream systems, downstream distribution and end-to-end data flow controls.
• Translate complex business logic into maintainable Java components with clear test coverage and operational controls.
• Engineer high-volume processing patterns including batching, parallel execution, queue-based decoupling, retry handling, idempotency and horizontal scalability.
• Develop validation and data‑quality controls that distinguish critical trade‑level errors from non‑critical attribute‑level gaps, with clear logging, traceability and error propagation.
• Contribute to automated regression testing and comparison frameworks for new output versus legacy baselines.
• Support UAT, production release preparation, issue triage, performance testing, monitoring, runbooks and L2/L3 handover.
• Partner with technical, business analysis, end user and production‑support teams.

• Proven hands‑on experience in Java engineering, ideally with Java 17 and/or Java 21.
• Experience developing applications using Spring Boot and the wider Spring ecosystem, including REST APIs, reactive programming (Flux), configuration management, dependency injection, and scalable, production‑ready service design.
• Experience building reliable integration services using REST APIs, messaging platforms, or queue‑based processing patterns.
• Ability to work with JSON data in Java, including large and complex payloads, evolving schemas, optional fields, malformed data scenarios, and performance optimization considerations.
• Good understanding of SQL and Oracle databases, with the ability to analyse, review, and support the migration of logic from PL/SQL packages and stored procedures.
• Experience working with concurrent and multi‑threaded applications, including batching, pagination, retry mechanisms, and high‑volume data ingestion.
• Experience using build and delivery tools such as Gradle or Maven, Git-based development workflows, peer code reviews, CI/CD pipelines, and structured release management processes.
