Field Service Engineer – Mechanical | Orange County, CA

Install, align and repair the robotic cells we build — at customer sites across the US

We’re DHR Engineering – an industrial automation company building thenext generation of production systems for some of the most ambitious innovators across the US and Europe. Our clients range from leading hardware startups to suppliers of major aerospace and automotive companies.

We don't do off-the-shelf and we don't do easy. We design, build and deploy custom robotic cells for CNC and CMM machine tending, automated 3D printer farms and AGV systems.

No unnecessary corporate layers and no pointless meetings: just real problems, smart solutions and machines you'll be proud to keep running.

Our machines are engineered and built in Europe, then shipped, built and commissioned on our customers' sites. About 90% of our customers are in the United States, and when things get critical, we are at their facility in under 12 hours.

We are currently expanding our US presence with a field service team in Huntington Beach, California.

We are looking for a Field Service Engineer with a strong mechanical background
. You will service our cells on customer sites, keep them running to the highest standards of both DHR and our customers, and fix whatever breaks — without compromise on safety and quality. You don't need to be an electrician: you need to understand the basics well enough to check a sensor, follow a schematic and work step by step with our electrical and controls engineers.

You will work alongside our electrical-focused service engineer and back each other up.

Location: Huntington Beach, CA

Travel: up to 50–70% to customer sites across the US

Type: Full-time

• Respond to service calls at customer sites and get machines back to work fast.
• Represent DHR Engineering in front of our customers: professional, reliable and the face of our company on their factory floor.
• Diagnose mechanical failures and decide on the fix — repair on site, replace the part, or send a diagnostic report to our engineers: grippers, vises, fixtures, tool-changing hardware, linear axes, ball screws, bearings, belts and gearboxes.
• Troubleshoot and repair pneumatic and hydraulic systems: valves, cylinders, regulators, leaks.
• Work together with engineers from our headquarters and take part in installations of new cells to build a deep understanding of our systems.
• Set up and adjust robot positions, fixtures and alignment tooling to specification, and recover robots from blocked or collision states safely back to their initial configuration.
• Check and replace sensors, cables and motors, and read I/O and alarms on the HMI under guidance from our engineers.
• Work with our engineers over video to find the root cause of faults that cross mechanical and electrical.
• Carry out preventive maintenance.
• Write clear service reports with photos and measurements: what failed, what was done, what is still open.
• Manage spare parts, source parts from local vendors when needed, assemble and install repair kits, and bring field lessons back to our design team.

As your experience grows, you will lead installations and become the reference for our US customers.

• 3+ years in field service, installation or maintenance of industrial machinery or automation equipment.
• Strong ability to read mechanical and assembly drawings and pneumatic/hydraulic schematics.
• Hands-on skill with precision measuring tools (calipers, micrometers, dial indicators) and machine alignment.
• Experience with power transmission and linear motion: bearings, belts, gearboxes, ball screws, linear guides.
• Safe work practices, including lockout/tagout and rigging/lifting.

• Able to read a basic electrical…
