Join Roche, where every voice matters.

Roche Support Network offers an exciting opportunity for individuals who are passionate about problem-solving and technical service excellence. As a Field Engineering Specialist – Mass Spectrometry, you will provide primary field engineering support, routine maintenance, and system installation for Roche’s fully automated mass spectrometry platform, the cobas i601, across customer laboratories within your assigned territory. Unlike traditional Core Lab liquid-phase diagnostic systems, automated clinical mass spectrometry introduces complex gas-phase ion physics, ultra-high vacuum (UHV) environments, and extreme-pressure fluidics.

In this role, you will perform hands‑on technical repair, system maintenance, and basic applications workflow support—partnering closely with National Field Engineering Specialists on complex escalations and multi‑system accounts. As a Field Engineering Specialist
- Mass Spectrometry, you will:

Showcase your technical expertise in servicing, repairing, calibrating, and installing cobas i601 mass spectrometry systems and associated automation in customer laboratories throughout your assigned territory.

Maintain specialized mass spec hardware, including ultra‑high vacuum (UHV) pumps, atmospheric pressure ionization (ESI/APCI) sources, electromagnetic ion optics, oscillating RF/DC quadrupoles, and high‑pressure LC fluidic pumps operating at thousands of PSI.

Perform deep molecular‑pathway preventive maintenance, including rebuilding and oiling vacuum pumps, cleaning ion sources and sampling capillaries, replacing LC components, and optimizing MS performance.

Diagnose and resolve mechanical, electronic, software, and gas/fluidic failures. Utilize data output—such as Total Ion Chromatograms (TIC), mass spectra (m/z ratios), and tuning logs—to troubleshoot hardware performance issues.

Collaborate with customer operators and FAS teams to support routine applications workflows. Provide guidance on basic operational practices, fluidic maintenance, vacuum integrity, and minimizing chemical interference/contamination.

Work closely with Advanced Engineering Specialists on high‑complexity accounts, major account rollouts, and advanced technical escalations.

Serve as a primary technical contact for service‑related issues, perform scheduled PMs, and maintain accurate service documentation using Roche's CRM system. Participate in on‑call rotations, providing after‑hours or weekend support as required.

High school diploma and 2 years of technical school or equivalent military training or equivalent work experience. 5 years of progressive experience repairing or servicing mechanical/system hardware and software, or networking/wireless networking OR a Bachelor's degree in Biomedical Engineering, Mechanical Engineering, Electrical Engineering, Chemistry or related field plus 1-2 years of progressive experience repairing or servicing complex mechanical/system hardware and software, or…
