  • Execute calculations
  • Capture structured outputs
  • Version results back to cloud storage
• Build session-isolated Windows worker processes that preserve desktop Excel behavior required by Office add-ins.
• Design scalable worker orchestration including scheduling, retries, concurrency control, and failure recovery.
• Validate workbook outputs before publishing results.
• Optimize throughput and reliability for large-scale monthly processing workloads.
• Collaborate with architects, DevOps, and infrastructure teams on deployment, VM images, scaling, and operational excellence.
• Troubleshoot performance, reliability, and interoperability issues across modern and legacy Windows environments.

Required Skills

• 6–16 years of professional software engineering experience.
• Strong production experience in C++ backend development.
• Python experience is desirable but not mandatory.
• Strong understanding of:
  • Backend services
  • APIs
  • Concurrency
  • Multithreading
  • Performance optimization
  • Debugging
• Experience building reliable enterprise production systems.
• Strong Windows development experience.
• Experience or willingness to work with:
  • Microsoft Excel automation
  • COM Automation
  • VSTO / Office Interop
  • Windows desktop automation
• Engineers with strong C++/.NET backgrounds who can quickly learn COM/VSTO automation are encouraged to apply.
• Experience with distributed processing, queues, retry mechanisms, and resilient service architecture.

Preferred Candidate Profile

We are looking for engineers who:

• Have strong production-grade C++ backend engineering experience.
