Full Job Description
We’re building something new within Evolution. This is not an iteration on an existing product or a role focused on maintaining established systems. It is a chance to help define a new platform from first principles, using modern backend technologies to solve hard engineering problems under real production constraints. The system we’re building will operate across regions and process thousands of real-money transactions per second with strict consistency guarantees. Low latency, correctness, performance, and security are not goals we optimise for later. They are design constraints from day one. We are looking for senior engineers who want to work close to the core of the platform: backend services, event-driven systems, databases, production infrastructure, and performance-critical product flows. 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 #
