# Mechanical Design Engineer [Propulsion]

**Company:** [Odys Aviation](https://hotfix.jobs/companies/odys-aviation)
**Location:** Long Beach, CA
**Role:** Hardware Engineering
**Experience:** 4+ years
**Skills:** Nx, CAD, GD&T, FEA, DFM, Dfa, Tolerance Stackups, Thermal Management, Teamcenter, Plm
**Posted:** 2026-05-05

> Designs, analyzes, and integrates mechanical and thermal systems for high-power hybrid-electric propulsion components like motors, generators, inverters, turbines, and cooling systems. Collaborates with cross-functional teams from concept through prototype testing and production.

## Job Description

## Responsibilities
- Own the mechanical design and integration of propulsion components and subsystems (motors, generators, inverters, turbines, structures and cooling systems)
- Drive resolution of real hardware issues discovered during prototype and early production builds
- Create and maintain 3D CAD models and 2D drawings, including GD&T and tolerance stackups
- Perform DFM/DFA trade studies, balancing weight, cost, thermal performance, reliability, and manufacturability
- Work with suppliers and internal teams to assess manufacturing feasibility, refine designs, and rapidly resolve build issues
- Support hands-on prototype assembly, integration, and test, including debugging and root cause analysis
- Conduct engineering analysis using a mix of hand calculations and FEA to inform design decisions
- Implement and refine thermal management strategies (air and/or liquid cooling, heat sinks, TIMs, enclosures, insulation)
- Translate test data and build feedback into actionable design improvements
- Document designs, analyses, and design changes clearly to support team alignment and future production

## Requirements
- B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, or a related field
- 4+ years of experience in mechanical design of complex systems (or equivalent demonstrated capability)
- Experience owning the design of a critical assembly or subsystem from concept through build, test, and iteration
- Proficiency in 3D CAD (NX preferred) and creating production-quality drawings with GD&T
- Strong understanding of tolerance stack-ups and real-world fit/integration challenges
- Experience designing for a range of manufacturing processes (machining, sheet metal, additive, etc.)
- Hands-on experience building, testing, and troubleshooting hardware
- Comfortable working on electromechanical systems (motors, power electronics, rotating machinery, batteries, cooling systems, etc.)
- Demonstrated ability to debug issues, perform root cause analysis, and drive corrective actions
- Experience working in fast-paced, iterative hardware development environments
- Strong problem-solving skills, attention to detail, and bias toward action
- Clear communicator who collaborates effectively across multidisciplinary teams

## Nice to Have
- Experience with propulsion systems or electromechanical systems
- Familiarity with rotating machinery, vibration, and structural dynamics considerations
- Background in thermal management of high-power systems (liquid cooling, forced air, heat exchangers)
- Experience performing thermal and/or structural analysis (FEA, analytical modeling, or CFD)
- Experience supporting prototype builds and early production environments
- Familiarity with PLM systems (Teamcenter preferred)
- Background in aerospace, automotive (EV/powertrain), robotics, or similar high-performance hardware industries
