We recently emerged from stealth with $50M in funding led by top-tier venture investors and strategic partners. Read more in our Press Release

As a Mechanical Engineering Technician, you will drive OEE gains on defense-critical production lines. You will partner with Manufacturing, Quality, and Controls to lift reliability, raise first-pass yield, and take time out of cycle. You will support Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT), including executing protocols, collecting data, and closing punch-list items. Some travel, including international in the first few months, may be required.

What You’ll Do

• Run and support Kaizen events that improve Availability, First-Pass Yield, and Throughput.

• Work with engineers to identify and remove bottlenecks on the line and document durable countermeasures.

• Design, build, and fit simple fixtures and production aids; use shop tools and basic fabrication as needed.

• Use internal tools to diagnose product and equipment issues, perform root cause analysis, and communicate corrective actions.

• Draft and update Manufacturing Instructions and assist with training operators and other technicians.

• Pull and analyze production data to spot patterns and propose solutions using Excel and, where helpful, Python, SQL, Minitab, or JMP.

• Support FAT/SAT mechanically: instrument stations, run acceptance tests, log results in MES, and help release equipment to production.

• Perform precision metrology and basic preventive maintenance to protect rate and quality.

What You’ll Bring

• Hands-on experience with hand and power tools and mechanical assembly, including fasteners, fits, torque methods, and alignment.

• Working knowledge of pneumatics and hydraulics; basic electro-mechanical skills are a plus (low-voltage sensors, harness repair, DMM use).

• Ability to read prints, GD&T, and schematics; comfortable interpreting 3D CAD. Experience with SolidWorks or similar is preferred.

• Exposure to fabrication or prototyping is helpful (machining basics, 3D printing, laser cutting).

• Proficiency with Microsoft Office and comfort using data tools to support decisions.

• Clear written and verbal communication; willingness to follow and improve SWIs and safety procedures (LOTO, cranes/rigging, forklifts).

• Ability to travel, including internationally during early equipment builds and SAT, as needed.

Required Qualifications

• Experience:

  • Tech I: 1–2+ years mechanical assembly/maintenance/prototyping.

  • Tech II: 3–5+ years owning setups, alignments, PMs, and quality checks.

• Tech III (Lead): 6+ years, cross-trade troubleshooting and mentoring.

• Core skills: Read prints & GD&T; precision assembly to tolerance; shop math; hand/power tools; basic mill/lathe/drill; hydraulics/pneumatics fundamentals; create clear notes/SWIs.

• Tempo: Demonstrated ability to meet rate and quality targets under time pressure while following SWIs and safety rules.

Preferred

• CAD literacy for simple fixture edits (SolidWorks or similar); ability to interpret 3D models.

• Exposure to PLC/VFD basics (status reads, alarm ack), sensors, and I/O checks (controls team will own programming).

• Experience with heat treat/thermal processes, hardness checks, and distortion control (nice to have for our parts).

• CMMS/MES and basic SPC; root-cause tools (5-Why, Ishikawa).

• Certifications: Forklift, overhead crane/rigging, OSHA-10; able to qualify for U.S. export-control programs if required by contract.
