Mechanical Engineer

Sterlitech Corporation•Auburn, WA
•$90,000 - $120,000

About The Position

The Mechanical Engineer is a hands-on engineer embedded with the Operations team, spending most of their time on the shop floor building and troubleshooting sub-assemblies and systems alongside the assembly team. The role keeps in-house fabrication equipment—including 3D printers, a laser cutter, fixtures, and tooling—running productively, and addresses technical problems that slow production. Rather than owning new product design, which belongs to Product Development, this engineer focuses on helping Operations build products consistently and efficiently. Responsibilities include developing fixtures and jigs, improving processes, maintaining work instructions and equipment uptime, and investigating root causes. The engineer takes ownership of problems from the initial report through a verified fix.

Requirements

  • Bachelor’s degree in mechanical engineering or a related field, or equivalent hands-on experience.
  • At least 2 years of experience in a manufacturing or hands-on engineering environment.
  • Proficiency in 3D CAD, such as SolidWorks or similar, and ability to read drawings, schematics, and BOMs.
  • Strong mechanical aptitude with hand and power tools, assembly, basic wiring, and plumbing.
  • A structured, persistent approach to troubleshooting and root-cause analysis.
  • Clear communication skills and ability to write work instructions that shop-floor staff can follow.

Nice To Haves

  • Experience operating and maintaining 3D printers and laser cutters.
  • Familiarity with fluid or hydraulic systems, filtration, NetSuite, or ISO 9001.

Responsibilities

  • Work with assemblers, the lead tech, and the test engineer to build, inspect, and test sub-assemblies and systems, including wiring, plumbing, and mechanical assembly.
  • Support complex or first-article builds and help clear production bottlenecks as needed.
  • Read and interpret drawings, schematics, P&IDs, and BOMs; report drawing or BOM errors to Product Development.
  • Provide technical problem-solving support to membrane production and the warehouse as needed.
  • Serve as the first technical responder when a build, test, or piece of equipment is not working.
  • Diagnose mechanical, pneumatic, hydraulic, and basic electrical issues on products and shop equipment.
  • Lead root-cause investigations into defects, nonconformances, and repeat failures, and implement corrective actions in line with the ISO 9001 quality system.
  • Own the setup, operation, maintenance, and calibration of in-house fabrication equipment, including 3D printers and the laser cutter.
  • Design and produce fixtures, jigs, gauges, tooling, and replacement or prototype parts using CAD, 3D printing, laser cutting, and basic machining.
  • Maintain equipment maintenance schedules, consumables, and spare parts, and coordinate with outside service vendors when needed.
  • Train operators in safe and correct equipment use, including laser safety requirements.
  • Identify and execute improvements that reduce assembly time, scrap, rework, and errors using Lean and continuous improvement methods such as kaizen, 5S, and mistake-proofing.
  • Create and maintain work instructions, SOPs, assembly aids, and test procedures that assemblers can use at the bench.
  • Keep routings, BOMs, and item data accurate in NetSuite (ERP) for supported products and processes.
  • Track production metrics such as cycle time, first-pass yield, and rework to identify improvement opportunities and assess results.
  • Act as the Operations technical liaison to Product Development on manufacturability, design changes, and new product introduction.
  • Provide Purchasing with technical input on parts, materials, substitutions, and new equipment.
  • Support Quality with inspections, first-article checks, and supplier part issues.
  • Help scope, install, and commission new manufacturing equipment.
  • Perform other duties as assigned.
