Principal Aerospace Engineer

Enigma Aerospace is seeking a highly experienced Principal Aerospace Engineer to lead the design, development, and integration of our large, next-generation autonomous aircraft system. This is a unique opportunity to join the founding team of a venture-backed aerospace company at the ground level. We’re looking for a hands‑on technical leader with a passion for aviation and a track record of delivering complex aerospace technologies.

In this role, you will have primary responsibility for the aircraft design, systems architecture, significantly contribute to the development and integration efforts, establish and manage vendor relationships, and help grow a high‑performing technical team. Success in this role requires deep experience in system architecture, cross‑functional design and development, systems integration, test, and operational readiness of large autonomous aircraft platforms.

• Lead the aircraft and systems design from initial development through build, test, and delivery to the manufacturing team
• Define and track key system‑level design parameters throughout the design
• Develop and validate simulation models for fixed‑wing aircraft dynamics, integrating aerodynamics, propulsion systems, avionics, and environmental factors
• Architect, model, simulate, and implement structural, avionics, propulsion, and flight controls systems to meet aircraft performance and stability
• Lead detailed structural, thermal, and electromagnetic analysis of critical airframe components to ensure durability, reliability, and compliance
• Forge and manage strong vendor relationships
• Ensure all sub‑systems work harmoniously together by defining, developing, and testing robust interfaces
• Embody a proactive and optimistic approach, bringing a can‑do attitude to the workplace every day, fostering a positive and dynamic work environment
• Travel up to 30% of the time, including domestic and international

• MS or higher degree in a relevant engineering field
• 10+ years of technical experience in the aerospace and/or defense industry, with experience working on large (>500 lbs. MTOW) fixed‑wing unmanned and/or autonomous aircraft systems
• Proven experience leading an aircraft design from requirements through prototyping to manufacturing
• Deep and broad knowledge of UAS sub‑systems from avionics to structures, mission software, and systems integration
• Experience with government programs or development of DoD technology
• Experience in the development and delivery to a schedule of a complex hardware and software system
• Excellent verbal and written communication skills with the ability to articulate problems and solutions to both technical and non‑technical individuals
• Excels at collaborating in a fast‑paced startup environment with changing priorities, technical requirements, and a growing team
• Must be eligible to work in the US

• Experience successfully delivering large, fixed‑wing UAS or autonomous aircraft(s) in a similar function
• Strong ability to quickly perform trade studies along design, components, systems, vendor dimensions and present to leadership
• Experience with lab and flight testing of aircraft and/or major subsystems
• Broad understanding across major aircraft systems (aerodynamics, flight controls, structures, avionics, propulsion including IC engines, mission software, etc.) with meaningful depth in at least one
• Experience with systems engineering, requirements management, CAD, software engineering, and program management tools
• You are an empathetic team‑player, who is an excellent listener and can persuasively communicate their ideas and plans to parties of all backgrounds
• You are an ambitious and self‑motivated individual who eagerly approaches ambiguity and is committed to delivering a high‑quality work product
