• Own delivery end-to-end: implementation, testing, migration cutover support, and production support
• Investigate production issues and drive root-cause analysis, translating findings into durable fixes
• Uphold high standards of execution quality - strong test coverage and performance discipline, especially given increased load from convergence
• Support incident management, post-incident remediation, and UAT for products migrating onto Orion

  We're looking for ambitious, talented, technical Java engineers to help build out Orion, with the US Clearing convergence as a defining near-term priority. This is a hands-on delivery role, and we're looking for engineers who bring genuine quality and excellence to their work: meticulous attention to detail, a motivated and self-driven approach, and a progressive mindset that continually raises the bar rather than settling for "good enough.", Bachelor's or Master's degree in Computer Science or a related technical field
