  • Partner closely with domain experts, platform engineers, and infrastructure teams to deliver scalable, maintainable solutions

What We're Looking For

  • 5+ years of professional software engineering experience
  • Strong hands-on Java development experience
  • Background building backend services, distributed systems, or data-processing platforms
  • Solid understanding of data structures, algorithms, concurrency, and system design
  • Experience working with multithreaded, asynchronous, or performance-sensitive applications
  • Familiarity with streaming, event-driven, time-series, or large-scale data systems
  • Exposure to cloud environments, monitoring/observability tools, CI/CD, and automated testing
  • Comfortable with Linux/Unix environments, SQL, Python, and scripting tools

Nice to Have

  • Experience within financial markets, trading technology, exchanges, or other high-volume data environments
  • Familiarity with technologies such as Kafka, Protobuf, gRPC, Parquet, REST APIs, and related tooling
