About this role
What You’ll Work With
You will work with technologies such as:
JavaSpring BootKafkaPostgreSQLDockerYou do not need to be an expert in every technology from day one, but you should have strong backend engineering fundamentals and a serious interest in building reliable distributed systems using this type of stack.
What You’ll Do
Build backend services and platform components using Java and Spring BootDesign and implement APIs, data models, internal tools, and product-facing systemsWork with Kafka-based event-driven architecture and high-throughput transaction flowsBuild systems using PostgreSQL, where performance, correctness, and observability matterBuild services designed to run in a modern containerised environmentContribute to technical decisions around consistency, latency, scalability, reliability, and securityWrite clear, maintainable, well-tested code with a strong focus on robustnessParticipate in code reviews, system design discussions, and technical trade-off decisions Who You Are
You have strong computer science fundamentalsYou are comfortable working with backend systems and databasesYou can reason clearly about correctness, concurrency, performance, and system designYou are interested in distributed systems, event-driven architecture, and production-grade engineeringYou learn quickly and enjoy working across different parts of the stackYou are ambitious, self-driven, and motivated to grow in a high-performing engineering environmentYou want to work in a small team with high standards and direct technical feedbackWhat Will Strengthen Your Application
Experience with Java and Spring BootExperience with Kafka or other event-streaming/message-driven systemsStrong understanding of PostgreSQL or relational database designExperience with Docker or containerised development workflowsExperience building systems where performance, correctness, reliability, or security matteredInternship experience or a few years of software engineering experience in a technically demanding environmentStrong academic results from a rigorous technical university or programPersonal, open-source, academic, or professional projects that show technical depth and ownershipCompetitive programming, hackathons, olympiads, research, or other high-signal technical achievementsClear communication and the ability to discuss technical trade-offs thoughtfully We’re building something new within Evolution
.
This is not a role focused on maintaining mature systems or working inside a fixed technical setup. It is an opportunity to help build 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 things we optimise for later. They are design constraints from day one.
We are looking for software engineers who want to work close to the core of the platform: backend services, event-driven systems, databases, and performance-critical product flows.
