YOUR IMPACT

As the Senior/Principal Lead Delivery Engineer for Aerospace, you own customer outcomes for Luminary's aerospace engagements — spanning established OEMs and the next generation building the future of flight and space. You are a dual hat — project manager and product manager — leading a matrixed value delivery team that translates the hardest problems in aircraft design, propulsion, aeroelasticity, and certification-relevant analysis and more into Physics AI solutions. You partner with the GTM team on account engagement and growth.

WHAT YOU'LL DO

• Own end-to-end customer outcomes across new and existing aerospace accounts — from discovery and use case scoping through model development, deployment, and embedding into customer engineering workflows.
• Author Statements of Work (SOWs), educate customers on the engagement plan, and own delivery accountability against them.
• Lead a value delivery team in a matrix structure: Applications Engineers, Applied AI/ML Scientists, Data and Platform Engineers, and selected product engineers. Set technical direction, sequence the work, remove blockers.
• Operate as a dual hat — project manager and product manager — running sprints, milestones, and risk while also choosing the right use cases and shaping the product intuition for what to build next.
• Stay hands-on-keyboard where it matters. Debug a model, restructure a data pipeline, prototype a workflow integration. Lead from the front, not from slides.
• Embrace co-engineering: work side-by-side with customers on use case development, sharing knowledge and building trust through visible, collaborative work.
• Partner with GTM team on new account engagement, GTM-to-delivery handoff, and account growth.
• Bring market and customer signal back to Product and Research, directly shaping Luminary's roadmap for aerospace use cases.

WHAT YOU BRING

• 5–10 years of experience in a technical role in aerospace — aerospace OEMs, eVTOL/UAM, space, propulsion, or aerospace-adjacent engineering software. Principal-level candidates have an extensive track record in aerospace. 
• Multi-physics fluency across aerospace disciplines: aerodynamics, structural mechanics, aeroelasticity, propulsion, thermal-structural coupling, composites, or multi-physics simulation. Generalist depth across several disciplines is more valuable than world-class depth in one.
• U.S. Person required.
• Strong hands-on engineering chops — Python, scripting, simulation tools, and AI/ML workflows.
• Working knowledge of AI/ML applied to engineering — surrogate modeling, neural operators, physics-informed ML, or digital twins.
• Demonstrated ability to lead cross-functional technical teams without direct authority.
• Product instinct, customer-facing presence, exceptional communication.
• Self-starter, persistent through iteration, willing to travel 10–25% to customer sites.

PREFERRED QUALIFICATIONS

• Advanced degree (MS or PhD) in Aerospace, Mechanical, or related field.
• Prior experience at commercial aerospace OEMs (Boeing, Airbus, Bombardier, Embraer, Textron), eVTOL/UAM (Joby, Archer, Wisk, Beta, Lilium), space (SpaceX, Blue Origin, Rocket Lab, Relativity, Stoke), or propulsion (Rolls-Royce, GE Aerospace, Pratt & Whitney, Safran).
• Hands-on experience with CFD, FEA, aeroelasticity, MDO, or certification-relevant analysis.
• Understanding of how AI-driven simulation integrates into aerospace development and certification workflows.
• Active or obtainable U.S. security clearance for engagements with cleared aerospace customers.
