Requirements
- Bachelor's Degree (4 years) - Mechanical Engineering, Mechatronics, or equivalent required (Master’s Degree preferred).
- 8+ year(s) in mechanical design and integration within automotive, aerospace, robotics, heavy machinery, or a high-innovation R&D environment.
- Advanced proficiency with 3D CAD platforms (SolidWorks or Onshape preferred) and 2D drafting/geometric dimensioning and tolerancing (GD&T) per ASME Y14.5.
- Structural Material Expertise: Deep knowledge of designing with aluminum, steel, and advanced materials, with an emphasis on sheet metal fabrication, welded structures, extrusions, castings, and machined components.
- Demonstrated mastery of linear and 2D tolerance stack-up analyses, joint design (bolted, welded, bonded), and component selection (fasteners, seals, materials, coatings).
- Strong hands-on experience running structural and modal analyses (ANSYS, Nastran, FEMAP, or equivalent) to validate design integrity under vibration and fatigue conditions.
- Proven experience designing IP-sealed enclosures, mounting solutions, and packaging for electromechanical systems in harsh environments.
- Direct experience working within a structured product lifecycle management (PLM) environment, including running configuration management, ECO processes, and generating complex BOMs.
- Experience managing external fabrication vendors and contract manufacturers from initial Request for Quote (RFQ) through final part delivery.
- Comfortable and skilled in a shop or lab environment, using hand tools, basic machining equipment, and diagnostics to support prototype assembly and fit-checks.
- Ability to read, write, speak, and understand English.
Nice To Haves
- Experience in leveraging AI tools to accelerate Mechanical Engineering workflow
- Experience in thermal design, CFD, heat exchangers, or heat sink optimization.
- Basic scripting skills in Python, MATLAB, or Go for design automation or data analysis.
Responsibilities
- Lead the mechanical engineering efforts for structural design, integration of hardware, and subsystem packaging from initial ideation through to final drawing release.
- Own the evolution of early-stage R&D concepts and custom retrofits into scalable, high-reliability, production-ready systems, ensuring designs meet structural, environmental, and safety standards.
- Execute finite element analyses (FEA) and first-order hand calculations to validate designs against static, dynamic, modal/vibration, and thermal use cases.
- Lead, mentor, and grow the mechanical engineering discipline by establishing best practices, standardizing workflows, conducting deep-dive design reviews, and guiding junior engineers.
- Optimize designs for manufacturing, assembly, and serviceability (DFM/DFA/DFS), collaborating closely with manufacturing, procurement, and external vendors.
- Pack and physically integrate sensors (cameras, LiDAR, radar, IMUs), compute units, and ancillary equipment, establishing clean routing paths for wire harnesses and cabling within tight mechanical envelopes.
- Design sealed, protective enclosures (IP-rated) and thermal solutions (cooling jackets, heat sinks) to safeguard sensitive electronic systems from vibration, dust, and thermal loads.
- Participate hands-on in physical bring-up, vehicle integration, and environmental testing campaigns (vibration, shock, thermal-vacuum, etc.), collaborating with validation teams to execute test plans.
- Maintain precise Bills of Materials (BOM), assembly documentation, tolerance budgets, and engineering change orders (ECO/DCO) within PDM/PLM systems.
- Serve as a key mechanical interface for non-mechanical engineering partners, translating physical constraints and structural trade-offs into clear systems-level decisions.
Benefits
- Multiple medical plans including a high deductible, low cost health plan
- Company-sponsored (paid) Short-Term Disability, Long-Term Disability, and Life Insurance
- Comprehensive optional benefits such as Dental, Vision, Supplemental Life/AD&D, Legal/ID Protection, and Accident and Critical Illness Insurance
- Generous paid time off options, including uncapped vacation days, the greater of 3 paid sick days or in accordance with the applicable state or local paid sick leave law, 6 paid company holidays, 2 floating holidays, parental leave, bereavement leave, jury duty leave, voting leave, and other forms of paid leave as required by applicable law or regulation
- Employee Stock Purchase Program with additional opportunities to earn stock in the Company
