## Description

At Roche you can show up as yourself, embraced for the unique qualities you bring. Our culture encourages personal expression, open dialogue, and genuine connections, where you are valued, accepted and respected for who you are, allowing you to thrive both personally and professionally. This is how we aim to prevent, stop and cure diseases and ensure everyone has access to healthcare today and for generations to come. Join Roche, where every voice matters. The Position Senior Field Engineering Specialist – Mass Spectrometry - Chicago A healthier future. It’s what drives us to innovate. To continuously advance science and ensure everyone has access to the healthcare they need today and for generations to come. Creating a world where we all have more time with the people we love. That’s what makes us Roche. The Opportunity Roche Support Network offers an exciting opportunity for individuals who are passionate about technical excellence and national leadership. As a National Field Engineering Specialist – Mass Spectrometry, you will serve as the country-wide Subject Matter Expert (SME) and top-tier technical authority for Roche’s fully automated mass spectrometry platform, the cobas i601. While strategically located within a designated home region, you will belong to a national expert team responsible for resolving the most challenging technical escalations across the United States. Unlike traditional Core Lab liquid-phase diagnostic systems, automated clinical mass spectrometry introduces complex gas-phase ion physics, ultra-high vacuum (UHV) systems, and extreme-pressure fluidics. In this high-level role, you will lead complex nationwide installations, advanced preventive maintenance, and deep diagnostic troubleshooting. You will also bridge the gap between engineering and applications workflows—training customer operators nationally, guiding application optimization, and serving as a senior technical mentor across the Roche Support Network. As a Senior Field Engineering Specialist, you will: Serve as National Technical SME: Act as the primary national escalation point for the installation, advanced service, calibration, and root-cause repair of cobas i601 mass spectrometry platforms across customer laboratories nationwide. Master Mass Spec & LC Hardware Engineering: Diagnose and repair specialized hardware, including ultra-high vacuum (UHV) pumps, atmospheric pressure ionization (ESI/APCI) sources, electromagnetic ion optics, oscillating RF/DC quadrupoles, and high-pressure/ultra-high pressure LC pumps operating at thousands of PSI. Lead Advanced Maintenance: Perform deep molecular-pathway preventive maintenance, including rebuilding and oiling vacuum pumps, cleaning ion sources and sampling capillaries, replacing LC columns, and optimizing detector/mass resolution settings. Applications & Workflow Integration: Cross-over into application workflow support by analyzing Total Ion Chromatograms (TIC), mass spectra (m/z ratios), isotopic distributions, and mass calibration tuning logs to diagnose root-cause hardware or separation issues. National Application & Technical Training: Deliver master-level technical and application workflow training to clinical lab personnel and internal service teams nationwide, covering platform operation, maintenance, fluidic care, vacuum integrity, and advanced troubleshooting. Contamination & Science-Based Troubleshooting: Resolve complex issues at the intersection of engineering and chemistry, such as chemical matrix suppression, isobaric cross-talk, micro-fluidic solvent leaks, and airborne chemical contamination (e.g., silicones/phthalates) affecting detector response. National Mentorship & Quality Standards: Drive continuous national quality improvements, document activities in Roche’s CRM system, mentor field engineers across all regions, and collaborate directly with global technical support and R&D teams. National Support & Travel: Serve as a dedicated resource for critical service-related
