Job description

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

THE COMPANY

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.

ABOUT THE ROLE

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

WHAT YOU'LL DO

• 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.

WHAT WE'RE LOOKING FOR

Mechanical (your strength)

• 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.

Electrical (working knowledge)

• Able to read a basic electrical schematic and use a multimeter.
• Understands 24 VDC sensors, solenoid valves and motor connections well enough to check and replace them.
• Basic understanding of PLC and HMI operation (reading I/O and alarms), ideally Siemens.

General

• A structured way of troubleshooting and comfort working with remote engineers in a different time zone.
• Good written and spoken English.
• Valid driver's license and willingness to travel frequently, sometimes on short notice.
• Authorized to work in the United States.

A university degree is not required. Practical skills, responsibility and quality of work matter more to us.

You don't need to tick every box; curiosity, rigor and ownership matter most.

WHAT'S A PLUS

• Experience with industrial robots and end-of-arm tooling.
• Experience with CNC machine tools (workholding, tool changes), CMMs or 3D printers.
• CAD and 3D printing skills: modelling and printing simple fixtures, brackets or replacement parts, e.g. SolidWorks, Inventor.
• A network of local vendors and machine shops for fast sourcing of parts.
• Forklift certification, welding or machining skills.
• Experience with a European equipment builder; Bulgarian or another European language.

WHAT WE OFFER

• Competitive salary based on experience, plus overtime pay and/or travel bonuses, as applicable.
• Health, dental and vision insurance; 401(k); paid time off and US holidays.
• A founding role in our US team, with a clear path toward service lead or commissioning engineer.
• Impactful work on custom robotics and automation projects — no two cells are the same.
• Company vehicle or mileage reimbursement, phone, laptop and professional tools.
• All travel expenses covered (flights, hotel, per diem).
• Direct line to the engineers who designed the machine, not a ticket queue.
• Training at our engineering and build facilities in Bulgaria.
• Projects for suppliers of leading aerospace, space and automotive companies.

If you like finding the fault nobody else could and want to see the machines you support run 24/7 in production, we’d like to hear from you.
