Mechanical Engineer – Unmanned Aircraft Systems (UAS)

Responsible for the design, development, and optimization of mechanical systems for unmanned aerial vehicles (UAVs) and other aerospace applications. The engineer will work with cross‑functional teams to advance UAS technologies in sectors such as defense, commercial aviation, and space exploration.

• Design mechanical components and systems for UAVs and other aerospace vehicles, including airframes, propulsion systems, control surfaces, landing gears, and payload integration.
• Build and test UAV prototypes to ensure mechanical reliability and performance, including ground and flight tests.
• Conduct stress, strain, and fatigue analysis on UAV structures and systems to ensure they can withstand operational conditions such as high speeds, altitudes, and varying temperatures.
• Design and analyze thermal systems to manage heat dissipation for high‑performance UAVs.
• Collaborate with electrical, avionics, and software engineers to integrate mechanical systems with sensors, communication, and control systems.
• Evaluate and select lightweight, high‑performance materials for UAVs, optimizing for fuel efficiency, durability, and strength.
• Perform root cause analysis on mechanical system failures and develop solutions to enhance safety and performance.
• Develop guidelines for inspection, maintenance, and repair of UAV mechanical systems to ensure long‑term operational efficiency.
• Ensure all designs meet relevant UAS regulations and industry standards.
• Engage in R&D for cutting‑edge UAS technologies, including autonomous systems, additive manufacturing, and advanced composite materials.
• Create detailed reports, design specifications, maintenance manuals, and testing documentation for UAS mechanical systems.

• Bachelor’s degree in Mechanical or Aerospace Engineering (or equivalent experience).
• 3–7+ years of engineering experience.

• Proficiency in CAD and mechanical design software (e.g., Solid Works).
• Knowledge of geometric dimensioning and tolerancing (GD&T) and drafting.
• Experience with design for manufacturability (DFMA) and tooling design.
• Experience with finite element analysis (FEA) and other simulation tools.
• Knowledge of fluid dynamics, thermodynamics, structural mechanics, and aerodynamics.
• Strong analytical and problem‑solving skills.
• Experience in project management.

• Proficiency in CAD for aerospace and UAS applications.
• Experience with detailed design, GD&T, and drafting.
• Understanding of UAV manufacturing processes, including 3D printing and advanced composite materials.
• Familiarity with UAV‑specific regulations and broader aerospace certification processes (e.g., DO‑160, AS9100).

Pay range for this role: $106,000 – $160,000 USD.

• Comprehensive medical, dental, vision, and life insurance options.
• 401(k) with company match.
• 4 weeks of paid time off each year.
• 12 annual company holidays.

• Innovative environment focused on cutting‑edge technology.
• Collaborative culture with passionate professionals.
• Opportunities for professional development and career advancement.
