About this role

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
