Job description

Neon Aero is looking for a Senior Mechanical Engineer to lead the design and integration of complex mechanical and electromechanical systems for next-generation hardware. You'll work across high-performance domains- positioning, propulsion, environmental control, energy management, and related technologies-supporting programs in aerospace, advanced mobility, robotics, and transportation.

This is a hands-on, highly collaborative role for an engineer who loves turning requirements into production-intent hardware that scales. You'll help architect robust systems, drive design into manufacturable solutions, and push hardware from concept prototype industrialization shipment.

Why This Role Matters:

In this role, you'll be a key driver of system-level execution-owning critical subsystems and making early decisions that determine whether hardware ships on time, at cost, and at quality.

You will:

  • Lead mechanical system design and integration across complex, multi-domain programs.
  • Own a subsystem end-to-end, from architecture and concept to production release.
  • Design and develop mechanical/electromechanical assemblies in Siemens NX (required).
  • Drive early DFM, DFA, DFAuto, and DFC decisions to ensure designs scale to production.
  • Apply strong GD&T fundamentals to create production-ready drawings and specs.
  • Partner with suppliers and manufacturing teams to industrialize parts, including first article builds and production ramp.
  • Define inspection approaches and understand manufacturing metrics like IQC, OQC, ORT, CP/CPK, tolerance stack-ups, and validation.
  • Support prototype builds, test campaigns, root-cause investigations, and design iterations.
  • Perform mechanical analysis as needed (FEA, thermal evaluation, structural validation).
  • Participate in design reviews and ensure performance, safety, reliability, cost, and schedule targets are met.
  • Provide hands-on support during assembly, integration, and testing-because the best systems engineers stay close to the hardware.

What you'll Bring:

  • Minimum of 8 years of experience in developing and shipping mechanical products
  • Bachelor's or Master's in Mechanical Engineering or related degree is preferred; relevant professional experience may be accepted in lieu of a degree.
  • Strong proficiency in Siemens NX is required.
  • Deep knowledge of GD&T and production-level drawing release practices.
  • Demonstrated experience bringing parts into production and shipping hardware.
  • Experience with multiple manufacturing processes, such as:
    • Sheet metal fabrication
    • Die casting
    • Gear manufacturing & finishing
    • High-precision machining (HPM/HDPM)
    • Injection molding or other scalable processes
  • Proven ability to work directly with suppliers to resolve tolerance, yield, and quality issues.
  • Solid understanding of quality systems and metrics: IQC, OQC, ORT, CP/CPK, SPC.
  • Strong cross-functional communication skills and a collaborative, systems-level mindset.

Preferred experience:

  • Aerospace or aviation systems experience.
  • Background in fast-iteration, high-performance environments (automotive, consumer hardware, racing, robotics, etc.).
  • Familiarity with DO-160 or similar environmental qualification standards.
  • MATLAB or Python for analysis/automation.
  • Experience with electric or hybrid propulsion systems.

Why Join Us:

  • Work alongside elite engineering talent and innovators from across aerospace and tech.
  • Be part of a team moving faster than the industry standard.
  • Shape solutions that are lower-cost, autonomous, and scalable - the future of aviation.
  • Competitive compensation, including equity participation, growth opportunities, and full heath benefits (health, vision, dental, 401K) designed to support you in and out of work.
