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.
What You’ll Work With
You will work with technologies such as:
- Java
- Spring Boot
- Kafka
- PostgreSQL
- Docker
You 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 Boot
- Design and implement APIs, data models, internal tools, and product-facing systems
- Work with Kafka-based event-driven architecture and high-throughput transaction flows
- Build systems using PostgreSQL, where performance, correctness, and observability matter
- Build services designed to run in a modern containerised environment
- Contribute to technical decisions around consistency, latency, scalability, reliability, and security
- Write clear, maintainable, well-tested code with a strong focus on robustness
- Participate in code reviews, system design discussions, and technical trade-off decisions
Who You Are
- You have strong computer science fundamentals
- You are comfortable working with backend systems and databases
- You can reason clearly about correctness, concurrency, performance, and system design
- You are interested in distributed systems, event-driven architecture, and production-grade engineering
- You learn quickly and enjoy working across different parts of the stack
- You are ambitious, self-driven, and motivated to grow in a high-performing engineering environment
- You want to work in a small team with high standards and direct technical feedback
What Will Strengthen Your Application
- Experience with Java and Spring Boot
- Experience with Kafka or other event-streaming/message-driven systems
- Strong understanding of PostgreSQL or relational database design
- Experience with Docker or containerised development workflows
- Experience building systems where performance, correctness, reliability, or security mattered
- Internship experience or a few years of software engineering experience in a technically demanding environment
- Strong academic results from a rigorous technical university or program
- Personal, open-source, academic, or professional projects that show technical depth and ownership
- Competitive programming, hackathons, olympiads, research, or other high-signal technical achievements
- Clear communication and the ability to discuss technical trade-offs thoughtfully
