IonQ’s computers will soon redefine industries like medicine, materials science, finance, artificial intelligence, machine learning, cryptography, and more. IonQ is at the forefront of this technological revolution.

At IDQ, an IonQ company, we change the world, one photon at a time. We harness light to develop and industrialize the most advanced quantum products and technologies and help to build long term trust. We offer quantum key distribution systems and quantum random number generators, and with them we provide the highest level of future-proof security. At IDQ, we have an unwavering commitment to quality and integrity with strong corporate governance based on the following values: transparency, respect, long-term trust, accountability, and courage.

As we continue to grow and advance our technological capabilities, we are seeking a talented and dedicated Field Service Engineer to join our team in US. In this role, you will be responsible for providing technical assistance and support (remote and on site) to our SNSPD (Supra-Nanowire Single Photon Detector) systems’ customers, and ensuring their inquiries and issues are addressed promptly and effectively. As this product embeds a lot of different technologies (cryogeny, deep vacuum, RF electronic, optical, PLC software, high-level software, network, etc.), this position requires a broad technical expertise, in addition to good communication skills and customer-centered approach.

Responsibilities:

Serve as the primary point of contact for customer inquiries and technical support requests, specifically on our cryogenic single photon detectors.
Diagnose and troubleshoot technical issues reported by customers, providing timely and accurate solutions.
Handle product training and installation, as well as guidance to customer, remotely or on customer site.
Collaborate with internal teams including R&D, Test and Manufacturing department, to escalate and resolve complex customer issues.
Document customer interactions, including issues reported and solutions provided.
Continuously improve customer support processes and procedures to enhance the overall customer experience.
Assist in the development of support documentation, FAQs, and knowledge base articles to help customers troubleshoot common issues independently.
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:

A degree in Industrial, Microtechnology, or Systems Engineering (or equivalent experience in a deep-tech environment).
Deep hands-on experience in at least three of the following: Cryogenics, UHV (Ultra-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.

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone.
