• Stay up to date on product features, updates, and industry trends to better assist customers and provide proactive support.

You’d be a good fit with:

• Undergraduate or graduate degree in Physics, Engineering Physics, Electrical Engineering or similar
• A demonstrated interest and experience in deploying precise and cutting-edge physics/optical instruments will be a plus
• Deep hands-on experience in at least three of the following: Cryogenics, (High Vacuum), Optical Metrology, RF Electronics, PLC Programming, or Network Architecture.
• A proven track record of troubleshooting complex, multi-disciplinary systems where hardware and software intersect.
• Ability to translate complex technical "hows" into clear "whys" for diverse stakeholders.
• Valid driver’s license and a willingness to travel for global on-site installations and high-level support.
• A self-starting mindset with the patience to navigate high-pressure technical roadblocks and the agility to thrive in a collaborative, fast-paced team.

You’d be a great fit with: 

• You don't just know three of the domains listed above; you understand how they influence each other (e.g., how RF noise affects optical measurements in cryogenic environments).
• Experience managing end-to-end installations or complex site surveys independently in international or sensitive environments.
• You have a "Product Ownership" mindset—you don’t just fix the bug; you identify the root cause and suggest design improvements to the R&D team.
• Proficiency in specific industry tools (e.g., LabVIEW, Python for automation, or advanced CAD viewers) that speed up the diagnostic process.
• Fluency in a second or third language, reflecting our global customer base.
• A history of coaching junior engineers or creating technical documentation that elevates the whole team’s knowledge base.

Location: This role will be based on-site at our Boston, MA office. We are open to hybrid and remote options for the right candidate.
Travel: 70% including international travel as required
