We ARE looking for engineers who: * Are excellent Python/backend engineers who build enterprise grade production systems well, and * Have real, demonstrable server-side Excel + COM add-in automation experience, and * Can wrap a fragile desktop-Office stack in robust, observable, scalable services. Good to Have: * Domain exposure to financial services / asset management / buy-side valuation workflows. * Reading/maintaining VBA macros; VSTO / .NET Office interop. * Direct experience with vendor Office add-ins - Capital IQ, Bloomberg, FactSet, MSCI, or similar. * RPA familiarity (UiPath, Power Automate) as a fallback where UI-level automation is unavoidable. * Observability (OpenTelemetry), IaC (Terraform), containerization, and Azure. * Delivery in regulated / audited environments (access control, evidence, change control). ## Description * Design, build, and operate production-grade backend services in Python - clean, tested, observable, and maintainable. * Own Excel execution engine: open workbooks, resolve add-ins, invoke an approved action, recalculate, and capture structured output with provenance. * Design interactive, session-isolated Windows/Excel workers and Preserve add-in behavior- real desktop sessions, which the COM add-ins require - and keep each run cleanly separated from the others. * Orchestrate the worker pool: distribute runs across many Excel workers with queues, scheduling, retries, and idempotency, so hundreds of workbooks flow through reliably and with built-in failure recovery * Validate outputs: confirm each run produced a complete, well-formed result (expected sheets/values present, no error states, integrity/hash checks) before it is trusted or written back. * Engineer for capacity: size and tune the worker pool to process the full workbook volume within the monthly-close window - concurrency limits, load/soak testing, and throughput/bottleneck analysis. * Contribute across the stack - system integration, debugging, performance optimization in a legacy-and-modern environment. * Collaborate with the Solution Architect on boundaries and with DevOps on VM imaging, scaling, and deployment; document and transfer knowledge. ## Related Videos - [Replacing Excel with SAP APIs & Python validation](https://www.wearedevelopers.com/videos/1944-replacing-excel-with-sap-apis-python-validation) - [How to achieve web automation with UiPath](https://www.wearedevelopers.com/videos/310-how-to-achieve-web-automation-with-uipath) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [RPA crash course for .Net developers – intro into the world of RPA from the perspective of a .Net developer](https://www.wearedevelopers.com/videos/271-rpa-crash-course-for-net-developers-intro-into-the-world-of-rpa-from-the-perspective-of-a-net-developer) - [Agentic employees in world's most downloaded FinTech app](https://www.wearedevelopers.com/videos/100123-agentic-employees-in-world-s-most-downloaded-fintech-app) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
