Senior Software Engineer – Backend Platform

What You’ll Work With You will work with a backend stack centred around: Java Spring Boot Kafka PostgreSQL Kubernetes What You’ll Do Build and evolve backend services and platform components using Java and Spring Boot Design APIs, data models, transaction flows, internal tools, and product-facing systems Design and build Kafka-based event-driven services and high-throughput transaction flows Design event flows with careful attention to ordering, idempotency, retries, failure handling, and data consistency Build systems using PostgreSQL where performance, correctness, and data integrity matter Deploy and operate backend services in Kubernetes-based production environments Drive technical decisions around consistency, latency, scalability, reliability, and security Make informed trade-offs between correctness, performance, complexity, and long-term maintainability Identify bottlenecks and continuously improve throughput, latency, observability, and system quality Own critical systems end-to-end, from design and implementation to production behaviour Strengthen engineering quality through code reviews, design discussions, and knowledge sharing Who You Are You have strong computer science fundamentals You have substantial experience building reliable, observable, high-performance backend systems You are comfortable working with distributed systems, databases, and production services You can reason clearly about correctness, concurrency, failure modes, performance, and system design You understand scalability beyond infrastructure alone, including data modelling, consistency, caching, and concurrency control You are comfortable making architectural decisions with long-term consequences You take ownership of problems and drive them to reliable outcomes You want to work in a small team with high standards and direct technical feedback What Will Strengthen Your Application Strong professional experience with Java and Spring Boot Strong experience with Kafka or similar event-streaming/message-driven systems Experience designing event flows with careful attention to ordering, idempotency, retries, failure handling, and data consistency Strong understanding of PostgreSQL, relational database design, transactions, indexing, and query performance Strong experience deploying, operating, or troubleshooting backend services in Kubernetes-based production environments Experience designing backend systems for high-throughput, low-latency, business-critical workloads Experience with distributed systems design, especially around consistency, partitioning, concurrency, and failure handling Experience with transactional data modelling and correctness guarantees in financial, gaming, trading, payments, or other high-integrity domains Experience with production observability, including metrics, tracing, structured logging, alerting, and performance analysis Security-minded engineering, including authentication, authorisation,…
