Senior Mechanical Engineer
$150k - $200kAmca Llc
Lead Mechanical Engineer
You will be a senior technical contributor on Amca's mechanical engineering team, owning the design, build, or test of flight hardware within a defined mechanical discipline — such as fluid systems, mechanisms, structural assemblies, cockpit avionics hardware, or power electronics packaging. You will work closely with the Mechanical Engineering Manager and cross-functional teams to take hardware from concept through qualification and into production. This is a deeply hands-on role for an engineer who thrives on hard technical problems, takes full ownership of their work, and is ready to grow into broader leadership over time.
Responsibilities:
- Serve as the technical lead for a defined mechanical discipline, owning design decisions and outcomes end-to-end
- Execute and oversee detailed design work including drawings, GD&T, FEA, component specifications, and risk assessments
- Drive hardware from bench prototype through qualification and production handoff, leveraging Amca's in-house R&D lab and protoshop
- Lead or support qualification campaigns including functional, environmental, pneumatic, hydraulic, and structural testing per MIL-STD and applicable aerospace standards
- Spearhead root cause investigations in development, production, and test; own corrective actions through resolution
- Ensure designs are optimized from day one for reliability, manufacturability, and cost
- Provide technical mentorship and informal guidance to less experienced engineers on the team
- Collaborate closely with mechanical, electrical, software, and build engineering to deliver integrated hardware systems
- Participate in design reviews and contribute to raising the technical bar across the mechanical engineering function
- Support customer-facing engagements and program reviews as a subject matter expert in your discipline
Qualifications:
- Substantial experience in mechanical engineering for aerospace or defense hardware, with a strong track record taking products from concept through flight qualification and into production
- Deep technical expertise in at least one mechanical discipline — such as fluid systems (pneumatic or hydraulic), mechanisms, structural design, cockpit avionics packaging, or power electronics enclosures — with working fluency across adjacent areas
- Hands-on and lab-comfortable; expected to be in the protoshop and on the bench, not just at a CAD station
- Strong command of engineering first principles across thermodynamics, fluid dynamics, and solid mechanics; proven ability to simplify requirements and cut complexity
- Experience with Siemens NX or equivalent CAD package; familiarity with FEA tools and test instrumentation
- Familiarity with MIL-STD-810, DO-160, and other aerospace qualification frameworks
- Independent, direct, and action-oriented; takes full ownership and thrives with minimal oversight
- Nascent leadership instincts — comfortable informally guiding peers and ready to grow into broader responsibility over time
