You have strong computer science fundamentalsYou have substantial experience building reliable, observable, high-performance backend systemsYou are comfortable working with distributed systems, databases, and production servicesYou can reason clearly about correctness, concurrency, failure modes, performance, and system designYou understand scalability beyond infrastructure alone, including data modelling, consistency, caching, and concurrency controlYou are comfortable making architectural decisions with long-term consequencesYou take ownership of problems and drive them to reliable outcomesYou want to work in a small team with high standards and direct technical feedbackWhat Will Strengthen Your Application
Strong professional experience with Java and Spring BootStrong experience with Kafka or similar event-streaming/message-driven systemsExperience designing event flows with careful attention to ordering, idempotency, retries, failure handling, and data consistencyStrong understanding of PostgreSQL, relational database design, transactions, indexing, and query performanceStrong experience deploying, operating, or troubleshooting backend services in Kubernetes-based production environmentsExperience designing backend systems for high-throughput, low-latency, business-critical workloadsExperience with distributed systems design, especially around consistency, partitioning, concurrency, and failure handlingExperience with transactional data modelling and correctness guarantees in financial, gaming, trading, payments, or other high-integrity domainsExperience with production observability, including metrics, tracing, structured logging, alerting, and performance analysisSecurity-minded engineering, including authentication, authorisation, secrets handling, secure service communication, and defensive designClear communication and the ability to discuss technical trade-offs thoughtfullyPayments, fintech, gaming, trading, or other real-money transaction domainsMulti-region system design with low-latency routing and strong data integrity guaranteesCaching and data-access strategies under strict correctness constraintsInfrastructure as code and automated delivery pipelinesLoad testing, capacity planning, and performance regression preventionIncident response and production reliability ownershipThis Role Is Likely Not for You If
You prefer clearly scoped implementation tasks over owning technical directionYou are uncomfortable making decisions with architectural or long-term design impactYour experience with backend systems at scale is limited or surface-levelYou tend to treat performance, scalability, reliability, or security as secondary concerns rather than core design constraintsAdditional Information
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.
