Senior Loads and Dynamics Engineer - Aeroelastics and Rotordynamics

Job description

About Zipline

Zipline is the world’s largest and most experienced drone delivery service. We are on a mission to serve all humans equally by ensuring access to food, medicine and essential goods anytime, anywhere. We design, build, and operate the world’s largest autonomous logistics system, delivering critical supplies quickly and reliably. Today, Zipline operates on four continents, makes a delivery somewhere in the world every 30 seconds, and has completed millions of deliveries to date, including blood, vaccines, medical supplies, food, and retail products.

Our customers include the world’s largest and most prominent healthcare systems, governments, retailers, restaurants and global businesses who rely on us to save lives, reduce emissions, increase economic opportunity, and provide delivery from point A to point B as fast as possible. The drone is only 15% of what we’ve built to enable seamless, reliable, global operations.

Our system strengthens supply chains, reduces congestion, and gives people time back. With more than 140 million commercial autonomous miles safely flown, Zipline is redefining access to healthcare, consumer products, and food across the globe.

We operate at a global scale and are looking for practical problem solvers who thrive on real-world challenges and rapid growth. Our team is motivated by building systems that have a direct, meaningful impact on people’s lives and by scaling the future of logistics. We are seeking people who sculpt from first principles, enjoy facing adversity, and can do the impossible at record breaking speeds.

About You and The Role

In this role, you will use your rotordynamics expertise to drive hardware and product design decisions. You will be responsible for the development and definition of rotor and propeller load cases, including setting and upholding analysis requirements, processes, and standards. You will conduct rotordynamics analyses and lead tight design-test-analysis loops to keep our delivery aircraft safe, light, and scalable. This role works closely with structures, aerodynamics, GNC, systems, and powertrain engineers to drive rotor system requirements and rotorcraft vehicle configuration decisions to achieve product level outcomes.

How to know if it's you: Pencil and paper calculations are always your first step, you prefer simple and fast over detailed and large, and you’re excited to get hands on with hardware. On any given day you could be driving design trade studies, supporting flight tests to validate analysis, or working across disciplines to tackle complex system level challenges.

Zipline was founded by engineers dedicated to making the world a better place. We are building a new global industry and are looking for a talented engineer who takes a hands-on approach and will use analysis to drive design. The ideal candidate will be someone who excels in a fast paced, dynamic environment and is excited to own and drive simple, elegant solutions to complex problems.

What You'll Do

• Own loads development for the propellers on Zipline’s aircraft

• Perform dynamic analyses of aircraft propellers, including structural modes, forced harmonic vibration, and rotordynamics simulations

• Define rotorcraft loads requirements that support flight performance and vehicle safety

• Build finite element models of propellers and powertrain components for structural and loads analyses

• Work with the aerodynamics and mechanical engineering teams to design high performance propeller and rotor blades

• Collaborate across hardware, software, and vehicle operations to drive rotorcraft configuration and performance decisions

• Evaluate static strength and fatigue life of dynamic system components, including rotor assemblies, propeller blades, and motor shafts.

• Execute propeller and aircraft testing from start-to-finish including pre-test analysis, instrumentation, testing, data analysis, signal processing and model correlation. Success will require a hands-on approach and quality time in wind tunnels, the vibration test lab, and on the flight line

• Level-up the engineering organization by providing mentorship, guidance, best practices, and building standardized in-house tools and processes

What You'll Bring

• Bachelor’s degree in aerospace engineering, mechanical engineering, or related field

• 7+ years of industry experience in design and analysis of rotor and vehicle structures. Preference for experience developing loads for eVTOL vehicles

• Expertise in helicopter/rotorcraft aeromechanics, including aerodynamics, dynamics, loads, stability, and performance

• Deep knowledge of RCAS, CAMRAD II, FlightLab, Dyrobes Rotor, or other comprehensive rotor analysis codes

• Experience with FEMAP/NASTRAN, Siemens Simcenter, or other finite element software

• Analytical/scientific programming experience (Python, MATLAB)

• Must-have traits: clear owner mentality with rapid decision cadence, tolerance for ambiguity and shifting configurat
