Top Engineering Jobs in Seattle, WA

Design and develop complex hydraulic fluid systems and mechanisms for autonomous UAV launch/recovery. Perform CAD, tolerance and materials selection, structural calculations and FEA, prototype and test hardware, support pre-production and flight testing, and collaborate across disciplines to meet performance, schedule, and reliability goals.

Perform finite element modeling and analyses (static, modal, fatigue, vibration) for UAV structures; validate results with hand calculations; support structural test planning, data analysis, load definition, and cross-functional design optimization to ensure lightweight, safe airframe performance.

Lead design and development of advanced electrical systems for autonomous aircraft, including circuit and subsystem design, part selection, schematic capture, simulation, verification, debugging, and production releases. Integrate embedded systems and sensors for autonomy, coordinate cross-functional teams, mentor engineers, define technical requirements, and develop automated test solutions to improve hardware reliability and production readiness.

Lead and contribute to design, analysis, and integration of launch/recovery mechanical systems from concept through production. Establish engineering standards, perform FMEA and reliability modeling, support testing and field operations, and manage a team of mechanical engineers while coordinating cross-functionally to ensure buildable, testable, and reliable designs.

Design, analyze, and deliver liquid cooling and thermal management systems for a jet-engine VTOL UAV (X-BAT). Own component/system design, supplier engagement, analysis/sizing, and support ground and flight test activities, including test-site travel.

Lead propulsion test development and execution for an afterburning jet-powered vehicle. Oversee design, build, and operation of test stands, instrumentation, and safety systems. Manage propulsion test engineers and technicians, define test objectives, perform thermodynamic and transient analysis, drive root-cause investigations, coordinate schedules and suppliers, and ensure test alignment with vehicle milestones.

Support environmental and stress testing, failure analysis, and reliability assessments for VBAT flight hardware. Collaborate with design, manufacturing, and suppliers to implement design-for-reliability practices, participate in FMEAs and design reviews, analyze test and field data, and develop corrective actions and process improvements. Use data tools (e.g., Python) and occasionally travel to support testing or supplier engagements.

Design, analyze, and validate aircraft power electronics (HV/LV systems, DC-DC converters, inverters, motor controllers, battery/BMS). Own full hardware lifecycle: modeling, schematic capture, PCB layout, prototyping, testing (HALT), verification, and cross-functional collaboration. Lead design reviews and manage program timelines to meet aerospace reliability and manufacturability standards.

Design and release primary and secondary structural components for an autonomous UAV. Execute conceptual through production design, perform hand stress calculations, support testing and validation, collaborate across disciplines, produce drawings and documentation, and work with manufacturing and flight test to resolve issues.

Lead mechanical design of rugged, deployable Ground Support Equipment (GSE) for next-generation UAS. Create CAD models and drawings, perform structural/thermal/fatigue analyses, run trade studies, oversee prototyping and testing, develop technical documentation, collaborate with manufacturing/suppliers, and support flight test campaigns to meet military and aviation standards.
