# Mechanical & Thermal Engineer [Propulsion]

**Company:** [Odys Aviation](https://hotfix.jobs/companies/odys-aviation)
**Location:** Long Beach, CA
**Role:** Hardware Engineering
**Experience:** 1+ years
**Skills:** CAD, Nx, FEA, Cfd, GD&T, DFM, Dfa, Thermal Analysis, Plm, Teamcenter
**Posted:** 2026-03-02

> Designs, analyzes, and integrates mechanical and thermal systems for high-power hybrid-electric propulsion components like motors, inverters, and turbines. Performs CAD modeling, FEA thermal analysis, GD&T, and supports prototyping and testing. Requires BS in Mechanical/Aerospace Engineering and 1-5 years experience.

## Job Description

## What You’ll Do
- Own the mechanical design, thermal analysis and integration of propulsion components and subsystems
- Resolve design, fit, thermal and integration issues discovered during prototype and early production builds, driving root cause analysis and corrective design actions
- Create and maintain 3D CAD models and 2D drawings, including GD&T and tolerance stackups
- Perform thermal analysis using hand calculations, **FEA**, and test correlation to guide design decisions
- Define and implement thermal management strategies for motors, inverters, and power electronics (**air and/or liquid cooling**, heat sinks, TIMs, enclosures, insulation)
- Perform **DFM/DFA** trade studies, balancing weight, cost, thermal performance, reliability, and manufacturability
- Work with suppliers and internal manufacturing partners to assess feasibility, fabrication methods, tolerances, and rapidly resolve build issues
- Provide hands on support during prototype and early production assembly, integration, and bench testing of propulsion hardware
- Support test planning, data review, design iteration, translating test results and build feedback into actionable improvements
- Document designs, design changes, analyses, and test results clearly

## What We’re Looking For
- **B.S. Mechanical Engineering, Aerospace Engineering** or a related field
- **1-5 years** of experience in mechanical design, thermal engineering, or closely related roles (internships and project experience count)
- Experience designing mechanical hardware using **CAD** to manage designs (**NX** preferred)
- Strong foundation of thermal analysis methods (**FEA**, analytical modeling or **CFD**)
- Familiarity with **GD&T** and tolerance stack up analysis
- Solid understanding of common manufacturing processes
- Comfortable working on electromechanical systems; exposure to motors, power electronics, or cooling systems is a plus
- Hands on mindset with interest in building, testing and iterating hardware
- Strong problem-solving skills and attention to detail
- Clear communicator who works well on multidisciplinary teams

## Nice to Have
- Experience with propulsion, power electronics packaging, or high-power electromechanical systems
- Exposure to **liquid cooling systems** or forced-air thermal design
- Hands-on experience building or troubleshooting hardware (projects, student teams, **UAVs**, robotics, racing, etc.)
- Comfort working in early, ambiguous designs with fast iteration cycles
- Familiarity with **PLM** tools (**Teamcenter** preferred)
