Skydweller Aero Inc. has its general and US headquarters in Oklahoma City, with European operations headquartered in Spain.
Role Summary
We are looking for a Senior Actuation Engineer to be the responsible engineer for our actuation products and for the actuation capabilities of our solar-powered unmanned aircraft.
You will own both from requirements and architecture through trade studies, design, supplier management, customer support, verification and installation, whether the actuator is used on its own or integrated on the aircraft.
You will keep requirements, interfaces and verification evidence aligned across the product and the aircraft.
This role can be based in Oklahoma City, OK (US) or Spain.
Responsibilities
Act as responsible engineer for our actuation products and for the actuation capabilities of our aircraft.
Own the design and design changes of a complete electromechanical actuator (motor, transmission, output stage, sensing, motor control, housing, and the interfaces between them), including the effect on requirements, suppliers and verification.
Perform trade studies of electromechanical actuation approaches for actuators and the control surfaces they drive.
Derive, allocate and maintain the requirements baseline,



including sizing and performance from loads, rates, redundancy, environmental constraints and the concept of operations, with traceability to design and verification.
Define the actuator architecture and its mechanical, electrical and control interfaces with the aircraft.
Perform preliminary design to validate requirements and support make/buy decisions for actuators, motors and motion control devices.
Direct mechanical and electrical designers during detailed design of the actuator and related hardware.
Manage subcontractors from contracting through requirements, testing and delivery.
Work with customers of the actuation products on requirements, interfaces, integration and in-service support.
Define and close verification for the actuator and for each actuation subsystem, including acceptance tests and laboratory and aircraft testing.
Create installation and checkout procedures for the actuator as a product and as installed on the aircraft.
Required Qualifications
Bachelor's degree in Mechanical, Aerospace, Electrical or Mechatronics Engineering, or a related field.
8+ years of experience in aerospace or defense, designing, building and testing motion control or actuation systems.
Proven experience owning the design of electromechanical actuators or similar motion control products, from requirements through verification.




Hands-on testing experience in support of hardware verification for an aerospace system.
Experience integrating software and hardware in flight-critical or safety-critical systems.
Strong understanding of motors, motor controllers, drive mechanisms and gearboxes.
Experience managing suppliers or subcontractors and working directly with customers.
Fluent English (written and spoken).
Preferred Qualifications
Master's degree in Mechanical, Aerospace, Electrical or Mechatronics Engineering.
10+ years of experience in aerospace or defense actuation systems.
Experience applying systems engineering to a hardware system: requirements derivation and traceability, interface definition and verification planning.
Experience with model-based systems engineering on a complex system, including architecture, interfaces and the link from requirements to verification.
Familiarity with ARP** for electromechanical actuation and ARP** for aircraft and system development.
Experience in hardware-in-the-loop (HIL) testing or in a system integration laboratory, in aerospace or another industry such as automotive, robotics or medical.
Experience designing test stations for verification testing, including harnesses, special test equipment, rack design, bills of materials and equipment procurement.
Experience with analog and digital converters, power supply components, analog troubleshooting, signal integrity, layout and grounding.
Applied experience with hard real-time operating systems and embedded systems.
Preferred Tools
Requirements management: Polarion ALM preferred; DOORS or similar tools welcome.
Model-based systems engineering: Cameo Systems Modeler, Capella, SCADE Architect, Enterprise Architect or similar.
