ob 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 a Python DevOps Engineer with 8–12 years of professional experience to develop secure, reliable automation frameworks based on Python, supported by PowerShell environments.

This role supports enterprise build automation, Python packaging, SBOM integration, and secure artifact publishing within a regulated environment. The position operates at the intersection of Engineering, DevOps, and Security to ensure compliant, traceable, and reproducible software distribution.

What will you do 

• Design and implement scalable Python components, refactor them strategically. Ensure reliable error handling and propagation across scripting environments. 
• Safeguard Code Quality, builds test strategy; enforces coverage gates               
• Automate Python packaging and build artifact generation using PyPI and Conda standards. Ensure security, traceability, and compliance with distributed Python packages. 
• Builds robust PowerShell scripts, including unittests (using Pester). 
• Improving platform architecture and operational efficiency: rationalizing dependencies, modularizing components, improving observability and reducing technical debt and operational cost.
• Collaborate with Development and CI/CD teams to automate artifact publishing and enforce compliance standards. 
• Maintain documentation and support troubleshooting of packaging and dependency workflows. 
• On Cyber Security, perform security code reviews, threat awareness. Implements automated scanning (SCA, CVE monitoring); manages SBOM. Integrate secrets into CI/CD securely   .
