• Own architecture decisions, design reviews, and technical standards adherence.
• Drive quality engineering: TDD/BDD, JUnit, Cucumber, secure coding, CI/CD enforcement.
• Collaborate with DevOps/SRE to enhance pipelines, automation, monitoring, and production readiness.
• Provide day‑to‑day technical leadership, mentoring engineers, and coordinating with 10+ dependent teams.
• Ensure compliance with regulatory timelines, non‑functional requirements, and audit‑ready documentation.
Must‑Have Experience
• Experience of hands‑on software engineering in financial services or high‑scale regulated environments.
• Team/technical leadership experience.
• Strong expertise in Java/J2EE, REST, microservices, and distributed systems.
• Payments experience: CHAPS, TARGET2, CBPR+, RTP, or similar.
• Oracle SQL/PL‑SQL and performance tuning for large transactional systems.
• Deep XML/JSON expertise; ISO 20022 transformations.
• Integration tech: Mule ESB, messaging, Kafka.
• Strong SDLC knowledge (Agile/Waterfall) plus CI/CD and DevOps tooling.
• TDD/integration testing frameworks (JUnit, Cucumber).
• Strong communication skills and ability to influence technical direction.
