  • Collaborate across a distributed team of engineers, product managers, and project managers.

What You’ll Bring

  • Strong Java (17+) fluency with experience in performance tuning.
  • Track record of designing and building systems for high throughput and low latency.
  • Hands‑on experience with agentic AI development: LLM integration, prompt engineering, and SDLC automation.
  • Solid understanding of middleware and messaging technologies such as Chronicle Queue, RabbitMQ, Aeron, and Kafka.
  • Working knowledge of Spring or Micronaut, Docker, and Kubernetes.
  • Deep knowledge of testing methodologies, SDLC practices, and CI/CD pipelines.
  • Ownership of the components the Exchange depends on.
