Role SummaryWe're looking for a Mechanical Engineer with high drive, low ego, and a genuine desire to own hard problems across our trailer platform. This role sits at the center of our hardware development process - you'll be hands-on with CAE, executing FEA models and validating designs through simulation, while also contributing directly to the physical design and integration of trailer subsystems.
The level is open. Whether you're early in your career and ready to build real skills fast, or an experienced engineer looking to take on significant technical ownership with minimal hand-holding, we want to talk. What matters is strong fundamentals, a bias toward execution, and genuine curiosity about how things work.
You'll partner closely with systems, electrical, and manufacturing teams to ensure designs are robust, manufacturable, and ready for the road.
Key Responsibilities- Develop and execute structural FEA models using CATIA & Ansys to validate trailer subsystems - chassis, suspension, enclosures, and structural interfaces
- Build and maintain load cases, boundary conditions, and simulation workflows that support design decisions across the mechanical team
- Perform durability, fatigue, and thermal analyses to ensure designs meet real-world operating requirements
- Lead or contribute to mechanical design efforts - component design, tolerance analysis, and drawing release - commensurate with experience level
- Collaborate with hardware, systems, and manufacturing teams to integrate analysis into the design cycle and drive design-for-manufacturability
- Correlate simulation results with physical test data; own root-cause analysis when designs don't perform as expected
- Document analysis methods, assumptions, and results to support design reviews and build institutional knowledge
What Success Looks Like (first 6-12 months)- Own FEA validation for major subsystems - from load case development through design sign-off
- Build repeatable simulation workflows that improve speed and consistency across the mechanical team
- Become a trusted resource for analysis-driven design feedback across hardware and systems teams
- Ship a meaningful contribution to the organization's physical design efforts - not just analysis support
Required Qualifications- Bachelor's or Master's in Mechanical Engineering, Automotive Engineering, or related field
- 2+ years of experience in mechanical design and/or structural analysis (internship and project team experience considered for strong candidates)
- Hands-on proficiency with FEA tools, preferably Ansys (Mechanical, Workbench)
- Experience with CAD tools (CATIA, NX, or SolidWorks)
- Solid understanding of structural mechanics, fatigue, and material behavior
- Ability to work independently, manage multiple tasks in parallel, and communicate findings clearly
Preferred / Nice-to-Haves- Experience in heavy vehicles, commercial trucks, trailers, or off-highway equipment
- Exposure to durability and fatigue analysis methods (stress-life, strain-life, damage accumulation)
- Familiarity with thermal analysis or CFD
- Experience correlating simulation results with physical test data
- Knowledge of ISO, SAE, or FMVSS standards for commercial vehicles
- Background in mentoring peers or leading technical efforts on a team
