What you'll bring

  • 5+ years of backend software engineering experience building production systems that handle real-time data, concurrency, and high availability
  • Strong, hands-on Scala expertise, including idiomatic Scala, functional patterns, testing with ScalaTest or similar tools, and comfort working in a large, existing Scala codebase
  • Experience with actor-based concurrency models, such as Akka, Pekko, or equivalent technologies, including an understanding of supervision, message passing, and backpressure
  • Solid relational database skills with PostgreSQL, including schema design, indexing, query optimization, and sound judgment about when to use JSONB versus a normalized structure
  • Comfort with event-driven architectures, message buses such as Kafka or Pub/Sub, and asynchronous workflows
  • Excellent troubleshooting skills, with the ability to read logs, trace requests across distributed systems, and isolate root causes under pressure
  • Demonstrated ability to write clear technical specifications, scope work realistically, and identify risks early
  • High standards for code, tests, documentation, and pull requests, along with a willingness to uphold those standards during code reviews
  • Ability to think on your feet and adapt quickly when priorities shift or unexpected issues arise
  • Outstanding written and verbal communication skills, with the ability to explain backend tradeoffs to technical and non-technical audiences
  • Self-starter who thrives in ambiguity and can manage multiple complex backend initiatives simultaneously
  • Experience with trading platforms, fintech, or capital markets technology
