  • Testing & Validation
  • Manufacturing / Machining
Key Responsibilities (by department):
1. Design Engineering
  • Support design and development of rotary engine components and subsystems using CAD tools (e.g., SolidWorks).
  • Perform tolerance analyses, DFMA reviews, and assist in prototype fabrication.
  • Collaborate with cross-functional teams on packaging, manufacturability, and integration challenges.
2. Aerospace Systems
  • Contribute to propulsion system integration for UAVs and other aerospace platforms.
  • Perform thermal and structural analyses under aerospace operating conditions.
  • Assist in compliance documentation and system-level testing.
3. Modeling & Simulation
  • Develop and run simulations for thermodynamic cycles and combustion analysis.
  • Use MATLAB, Simulink, GT-Power, ANSYS, or other modeling tools to support performance prediction and optimization.
  • Validate simulation results against experimental data.
4. Testing & Validation
  • Support test setup, data acquisition, and instrumentation for engine and component testing.
  • Analyze test data to identify trends, issues, and performance metrics.
  • Assist with writing test plans, procedures, and reports.
5. Manufacturing Engineering / Machinist
  • Operate and support CNC machining, manual lathe, and mill equipment for prototype and low-volume production.
  • Assist in fixture design, tool selection, and machining process planning.
  • Work closely with design engineers to evaluate manufacturability and implement design changes.
  • Maintain precision, quality control, and safety standards during part fabrication.
  • Gain hands-on experience with GD&T, CAM programming (e.g., Fusion 360 or Mastercam), and material selection.
Qualifications:
  • Currently pursuing a Bachelor’s or Associate’s degree in Mechanical Engineering, Aerospace Engineering, Manufacturing Engineering, or a related technical field. Technical trade school students will also be considered for machinist roles.
  • Strong analytical and problem-solving skills.
  • Experience with relevant tools depending on the department (e.g., SolidWorks, MATLAB, Python, LabVIEW, CNC equipment, CAM software).
  • Excellent communication and teamwork abilities.
  • Passion for innovation and technology development.
Preferred Skills (not required, but a plus):
  • Prior experience with internal combustion engines, power systems, or mechanical prototyping.
  • Knowledge of thermodynamics, fluid dynamics, or heat transfer.
  • Familiarity with electric drive systems, UAVs, or hybrid propulsion.
  • Hands-on experience in a shop environment or with machining equipment.
What You'll Gain:
  • Hands-on experience working with cutting-edge engine technologies.
  • Mentorship from experienced engineers and exposure to startup culture.
  • Opportunity to work on high-impact projects in aerospace and defense.
  • Practical manufacturing and prototyping skills in a real-world R&D environment.
  • Potential pathway to full-time employment.
Compensation:
  • Approximately $3000-3850/month depending on the year in school.
