Hydraulic Assembly Technician

About the role

The Maritime Manufacturing Technology team is responsible for rapidly developing and implementing manufacturing technologies and processes for cutting-edge defense hardware, including deployable static and moving surface, undersea and sea to air vehicles and scaling these products in our new manufacturing facilities. As a Hydraulic Assembly Technician, you'll build up the hydraulic assemblies that open or actuate doors, operate valves, and drive launch mechanisms, systems that run at 3,000+ PSI with zero tolerance for leakage or contamination. Your work spans precision assembly of cylinders, actuators, valve manifolds, hydraulic power units (HPUs), and accumulator banks. Every assembly you build will be proof-tested and inspected to naval or program standards before it leaves your bench.

Responsibilities

• Assemble hydraulic cylinders, actuators, servo valves, manifold blocks, HPUs, and accumulator banks per engineering drawings and work instructions.
• Install seals, O-rings, backup rings, and dynamic sealing elements using proper lubrication, orientation, and stretch/compression specs.
• Fit, lap, hone, and scrape mating surfaces to achieve required surface finishes and seal-face flatness.
• Torque fasteners to spec using calibrated hand tools and hydraulic torque equipment.
• Assemble and plumb hydraulic tubing, fittings, and flex hoses within self-contained subassemblies.
• Perform hydrostatic proof-pressure and leak testing on completed assemblies.
• Conduct pneumatic (air) testing where required by procedure.
• Perform functional testing: stroke cylinders, cycle valves, verify actuator response and speed.
• Document test results, pressures, leak rates, and cycle counts per quality requirements.
• Identify and troubleshoot failures: disassemble, diagnose root cause, replace components, and re-test.
• Complete hardcopy and electronic documentation: assembly travelers, inspection records, material traceability, torque logs.
• Maintain compliance with SUBSAFE, SOC, and Level I requirements as applicable to submarine hydraulic systems.
• Support customer and government inspections of completed assemblies.
• Identify non-conformances and process through proper disposition channels.
• REQUIRED QUALIFICATIONS
• High school diploma or GED.
• 5+ years of hydraulic assembly, hydraulic maintenance, or precision mechanical assembly experience.
• Ability to read and interpret mechanical assembly drawings, hydraulic schematics, and detail drawings.
• Experience with precision measuring tools (micrometers, calipers, bore gauges, dial indicators).
• Proficiency installing hydraulic seals, O-rings, and dynamic sealing elements.
• Experience with torque-controlled fastener installation.
• Familiarity with hydrostatic and pneumatic test procedures.
• Willing to work any shift and overtime as production requires.
• Must be a U.S. Person due to required access to U.S. export controlled information or facilities.
• Eligible to obtain and maintain an active U.S. Secret security clearance.

Requirements

• Experience with SUBSAFE, SOC, or Level I controlled hydraulic assemblies.
• Military shipbuilding, submarine, or naval shipyard experience.
• Experience with cleanliness-controlled assembly (NAS 1638, ISO 4406, or equivalent).
• Background in aerospace, defense, or AS9100 / ISO 9001 environments.
• Familiarity with hydraulic power units, accumulators, and servo valve assemblies.
• Fluid power certification (IFPS or equivalent).
• Experience with hydraulic cylinder rebuild and actuator overhaul.
• Completion of apprenticeship, vocational program, or military MOS in hydraulic/mechanical systems (e.g., Navy HT, GSM, or equivalent).
• US Hourly Range
• $99,000 - $130,000 USD
