Sr. Propulsion Engineer

Job Description

We are seeking a Sr. Propulsion Engineer to oversee the integration, validation, and lifecycle management of propulsion systems for our UAV platforms. This role requires a multi‑disciplinary leader who can bridge mechanical, aerospace, and systems engineering to ensure engines (including heavy fuel and gas‑powered systems) meet performance, weight, endurance, and environmental requirements for Group 3 UAVs. The ideal candidate will have a strong background in propulsion system integration, vendor collaboration, and UAV development.

• Propulsion System Leadership
  • Act as the technical authority for propulsion systems.
  • Define system requirements, responsible for engine integration and verification methods.
  • Collaborate with vendors to troubleshoot performance issues and drive design improvements.
• Cross‑Functional Integration
  • Work with aerodynamics, structural, and avionics teams to optimize engine placement, cooling, and vibration mitigation.
  • Ensure propulsion systems align with UAV mission profiles (e.g., endurance, payload capacity, altitude, temperature, and other environmental factors).
• Testing & Validation
  • Lead ground and flight testing campaigns to validate engine performance under operational conditions.
  • Analyze data to refine system parameters and ensure compliance with military standards.
• Vendor & Customer Management
  • Serve as the primary technical liaison between internal teams and propulsion system vendors.
  • Review vendor designs, conduct risk assessments, and ensure deliverables meet project timelines.
  • Support customer engagements to resolve requirements ambiguity and confusion.
• Lifecycle Support
  • Develop maintenance protocols and failure‑mode analyses for propulsion systems.
  • Support field operations teams in diagnosing and resolving engine‑related issues.
  • Develop and maintain strategic alignment of Maintenance, Repair and Overhaul (MRO) operations.

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or related field (Master’s preferred).
• 8+ years of systems engineering development experience.
• 5+ years in propulsion system design, integration, and test, preferably with gas or heavy fuel engines.
• Knowledge of power and propulsion system and subsystem components such as fuel systems, emissions control, propulsion‑airframe integration, and ground equipment.
• Proven experience managing vendor partnerships and cross‑functional engineering teams.
• Strong project management abilities (Agile, SCRUM, or similar frameworks).
• Ability to thrive in a fast‑paced, dynamic environment, managing multiple priorities and deadlines.
• Excellent communication skills for technical and non‑technical stakeholders.

• Background in UAV development, particularly Group 2/3 UAVs or similar mid‑sized platforms.
• Experience with heavy fuel engines and maritime operations.
• Knowledge of DO‑160, MIL‑STD‑461, or other aerospace environmental testing standards.
• Prior technical lead roles in UAV or defense/aerospace projects.

• Ability to work in an office (constant).
• Required to sit and stand for long periods; talk, hear, and use hands and fingers to operate a computer and telephone keyboard (frequent).
