Job description

Application Engineer, Additive Manufacturing

San Diego, CA, USA

USD 100k-130k / year + Equity

Full-time

In office

What You'll Do

• Application development — take customer part requirements and turn them into validated, repeatable manufacturing processes on xCell across additive (MJF, FDM, metal) and CNC, from DFM/DFAM through first article
• Process & materials engineering — develop and qualify process parameters, materials, and the part libraries and work instructions that let operators produce to spec without you in the room
• Field & deployment support — support xCell deployments, train and enable operators, and troubleshoot production issues on fielded systems in both CONUS and OCONUS environments
• Customer engagement — work directly with warfighters and program customers to understand the applications they care about and translate mission needs into what xCell can produce
• Sustaining & quality — own first-article inspection and part qualification, and when a fielded system fails to deliver as advertised, drive the process- and application-level fix
• Cross-functional feedback loop — feed real application and field data back to systems, mechanical, and manufacturing engineering to sharpen the next generation of xCell
• Have a high ownership mentality — you close loops, you don't wait to be told, and you hold yourself and others to a high standard

Required Qualifications

• Bachelor's degree in Engineering (Mechanical, Manufacturing, Materials, or related field)
• U.S. Citizenship required due to ITAR regulations, with the ability to obtain and maintain a DoD security clearance
• 1+ years of hands‑on experience with MJF (Multi‑Jet Fusion)
• 3+ years of experience in a manufacturing environment
• Design for Additive Manufacturing (DfAM) fluency — you know how to make a part printable
• Comfortable troubleshooting hardware and process problems in a dynamic environment, where the answer isn't always clear and speed matters
• Proficiency with CAD (SolidWorks preferred)

Preferred Qualifications

• Defense background — you understand the operational context your hardware will live in
• FDM, SLA, SLS, Metal additive or CNC process development and qualification experience
• Materials qualification, GD&T, and first‑article / PPAP‑style inspection experience
• Experience training or supporting customers on utilizing their fielded manufacturing equipment via remote/hands‑on support.
• Familiarity with PLM and quality/documentation systems

Why This Role, Why Now

xCell only matters if it makes what the warfighter needs, where they need it — and someone has to own the part that turns a capable machine into a reliable one in the field. That's this role. The engineers who join now will define how we qualify, deploy, and scale what xCell can produce, and they'll do it on a team that takes the work seriously and moves with urgency. If you want real responsibility and near‑term impact on a fielded defense platform, let's talk.

We're roughly 150 people, headquartered in San Diego, and we're past concept — xCell systems are in the field in both OCONUS and CONUS today and our development pipeline is aggressive.
