Job Title: Hydraulic Cylinder Build & Test Specialist

Company: DNC Hydraulics LLC

Employment Type: Full-Time w/Overtime

DNC Hydraulics is a fast-growing hydraulic service, repair, and manufacturing company serving heavy industry, steel mills, and demanding customers who expect work done right — not done twice. We specialize in complex hydraulic cylinders where precision, reliability, and pride in craftsmanship matter. This is not a production-line assembly. This is skilled mechanical work from start to finish.

The Hydraulic Cylinder Build & Test Specialist is responsible for assembling, testing, and finalizing hydraulic cylinders to exact specifications. This role requires strong mechanical aptitude, attention to detail, and the finesse to work with tight tolerances, seals, and finishes without damage. If you enjoy building complex mechanical systems, seeing a job through to completion, and knowing your work directly impacts customer uptime – this role is for you.

• Assemble hydraulic cylinders according to drawings, specifications, and work orders.
• Install seals, bearings, pistons, rods, and components with precision and care.
• Perform pressure testing, function testing, and final inspections.
• Identify issues during assembly or testing and communicate clearly with analysts or leadership.
• Maintain clean, organized work areas and proper handling of precision components.
• Follow quality standards, safety procedures, and documented processes.
• Support continuous improvement in build methods, tooling, and workflow.
• Work additional hours when workload and customer demand require it.

• High mechanical aptitude with hands-on experience assembling mechanical or hydraulic components.
• Strong attention to detail and patience — seal damage, shortcuts, and rework are not acceptable.
• Ability to read and follow drawings, specifications, and instructions.
• Comfortable using hand tools, torque tools, measuring equipment, and lifting devices.
• Pride in craftsmanship and completing jobs correctly the first time.
• Willingness to work as part of a team and support overall throughput.
• Reliable attendance and a strong work ethic.

• Previous hydraulic cylinder builds or repair experience.
• Experience with pressure testing hydraulic systems.
• Exposure to heavy industrial or mill-duty equipment.

• Trade school or technical training.
• 3 years’ experience at DNC Hydraulics.

• 40 hours is the minimum expectation.
• This role requires flexibility to work approximately 45-55 hours during busy periods.
• Overtime is workload-driven, not permanent.
• Team members are expected to support each other when demand is high.

• Competitive pay (Salary to be determined by the applicant’s education, experience, knowledge, skills, and abilities, as well as internal equity and alignment with market data.)
• Full-time, consistent hours.
• Opportunity to grow within a well-established company.
• Supportive team environment.
• 401K (After 1 year of service).
