Principal Engineer (AWS & Java)

Join our team as a Principal Engineer, where you will be the senior hands-on technical expert for our Risk Screening platform. You will work closely with architecture, service, product, and engineering teams to ensure the highest technical and operational standards are met. Your core focus will be on the system's non-functional characteristics, including end-to-end latency, cloud scalability, resilience, and data handling. You will provide deep technical guidance, tackle complex challenges, and set the standard for quality and performance across all engineering teams.

• Act as the senior-most technical authority for implementation within the Risk Screening platform, ensuring designs are realized accurately and pragmatically.
• Lead the implementation of the most complex and business-critical changes, setting the standard for quality, performance, and maintainability.
• Drive solutions for cloud scaling and capacity management, ensuring the platform performs predictably under variable and peak loads.
• Ability to influence and guide teams through technical credibility rather than formal authority
• Strong understanding of production operations, including incident management, observability, and reliability engineering
• Deep, hands‑on expertise in Java (Java 11+ preferred), including JVM behaviour, concurrency, and performance optimisation
• Extensive experience as a Principal Engineer, or equivalent senior technical role on large‑scale, production systems
• Strong experience working with large databases or data platforms, including performance tuning and operational management
• Strong, practical experience building and running systems on AWS, with a focus on real‑world operational trade‑offs
• Proven ability to implement and operate distributed systems at scale, with particular emphasis on performance and scalability
