  • Take end-to-end ownership of new features from initial design and technical proof of concept to production rollout.
  • Build resilient, high-throughput back-end microservices using Java 17+ or Kotlin on top of the Spring ecosystem.
  • Craft responsive, reliable, and intuitive user interfaces using modern web standards and React.
  • Implement low-latency REST APIs, WebSocket streaming, and event-driven communication protocols across distributed components.
  • Design efficient relational data models in PostgreSQL, optimize persistence layers, and ensure smooth data pipelines.
  • Troubleshoot intricate issues across distributed environments while safeguarding system reliability, performance, and security.
  • Contribute actively to technical discussions, architectural roadmaps, code reviews, and continuous delivery improvements.

Your profile:

  • Solid track record in full-stack software development spanning enterprise back-end architectures and modern web front ends.
  • Strong programming proficiency in Java 17+ and/or Kotlin, complemented by practical experience with Spring and Hibernate.
  • Hands-on familiarity with modern JavaScript, CSS, HTML, and client-side component libraries, ideally React.
  • Solid understanding of relational database design, SQL optimization (ideally PostgreSQL), and distributed messaging patterns.
  • Rigorous approach to clean code, testing, Git workflows, and agile collaboration in multidisciplinary engineering squads.
  • Strong analytical reasoning, self-reliance in technical problem-solving, and continuous appetite for mastering emerging technologies.
  • Helpful bonus assets include exposure to Protobuf, gRPC, RabbitMQ, WebSockets, Docker, CI/CD pipelines, or high-throughput financial and energy trading environments.
