Senior Infrastructure Automation and Windows Platform Engineer

Job Title 

Senior Engineer – Infrastructure Automation & Windows Platform Engineering  

Job Description 

When you join us at Thermo Fisher Scientific, you’ll become a member of a hard-working, motivated team that aligns with your enthusiasm for exploration and discovery. With revenues exceeding $40 billion and the largest investment in R&D in the industry, we provide our people with resources and opportunities to make significant contributions to the world. 

How will you make an impact 

Work on backend platform software that powers advanced scientific instruments used in semiconductors, life sciences, and materials research. We are seeking an experienced senior developer (4–6 years) to drive reliable, scalable VM infrastructure automation and CI/CD execution for engineering workflows such as smoke and integration testing, regression, and continuous integration. This role will lead the delivery of automation services and tooling built primarily in Python and C#, with strong emphasis on Windows platform engineering, Jenkins (Groovy/shared libraries) and operational reliability. 

The ideal candidate combines strong hands-on technical depth with the ability to set direction, improve system stability, mentor engineers, and support rapid troubleshooting when CI pipelines or VM automation workflows encounter issues. 

What will you do  

• Development of backend automation services (Python/C#) for process execution, file operations, health checks, and environment management. 

• Establish strong reliability practices (logging/monitoring, retries/backoff, idempotency, concurrency controls, safe cleanup, traceability). 

• Provide Windows platform understanding (Event Logs, Registry, services) to diagnose and resolve complex automation and CI issues. 

• Support incident response and hands-on troubleshooting to reduce downtime and improve resilience. 

• Guide test execution optimization (including incremental testing) to improve CI cycle time and stability. 

• Influence technical design and architecture and maintain clear runbooks and documentation for operational readiness. 

Required Skills 

• Strong hands-on experience with Python and C# in complex, production-grade engineering environments. 

• TypeScript / Node.js exposure for tooling, services, or automation utilities. 

• Strong Windows automation and troubleshooting skills using PowerShell and BATCH scripting, including deep knowledge of Windows internals (Event Log, Registry, services). 

• Experience with both relational and non-relational databases (e.g., MariaDB, MongoDB). 

• Practical troubleshooting mindset and comfort handling ad-hoc firefighting / incident response scenarios. 

• Working knowledge of software design/architecture fundamentals and testing concepts, including incremental testing approaches. 

• Exposure to .NET build/test workflows to support cross-team collaboration. 

Desirable Skills 

• Experience with Go and/or PHP in platform or automation contexts. 

• Familiarity with artifact publishing and release governance practices (e.g., JFrog CLI, promotion patterns). 

• Own Jenkins automation at scale (Groovy pipelines/shared libraries), improving reliability through standards, guardrails, and reusable patterns. 

• Proficiency in OpenStack services like Nova (compute), Neutron (networking), and Cinder (storage). 

Preferred Qualifications 

• BTech degree in Computer Science, Electronics, or a related technical field (or equivalent practical experience). 

• Experience operating in regulated or security-focused environments require auditability and traceability.
