Top Engineering Jobs in Seattle, WA

Design and release propulsion hardware for a low-bypass turbofan UAV across engine, fuel, oil, and bleed air systems. Create CAD models/drawings (Siemens NX), apply GD&T, support manufacturing, testing, BOM/configuration control, analyses (hand calcs, FEA, GFSSP, REFPROP), and collaborate with production, flight test, and cross-functional teams.

Support avionics design, verification, procurement, manufacturing, and test for X-BAT. Execute test campaigns, perform environmental qualification, debug circuits, design PCBAs and harnesses, set up lab and prototype manufacturing, and document results.

Integrate, characterize, calibrate, and validate multi-modal navigation sensors (IMUs, GNSS, cameras, altimeters). Develop test plans, calibration scripts, and data-processing tools; collaborate across electrical, mechanical, and software teams; support schematics, CAD, drivers, and lab-based sensor testing through production.

Develop and implement real-time sensor processing and multi-sensor state estimation algorithms (IMU, radar, cameras, GPS). Design pipelines, run field tests, integrate with cross-functional teams, and optimize for production on compute-constrained systems.

Design and implement high-quality C/C++ embedded avionics software for X-Bat UAVs. Lead cross-functional teams, own features from design to production, integrate firmware and autonomy systems, and develop HIL/virtualized test environments. Produce architecture and test documentation, build CI/test tools, prototype concepts, and ensure reliability, safety, and compliance for aerospace deployments.

Lead mechanical design and spatial integration of secondary support structures and subsystem installations for aerospace vehicles. Develop CAD models, installation drawings, routing solutions (EWIS, hydraulic, ECS, fuel, pneumatic), perform fitment and tolerance analyses, define installation strategies, support procurement/fabrication and prototype builds, and coordinate across manufacturing, structures, avionics, systems, and test teams through design reviews and BOM management.

Lead and grow the mechanical engineering team for avionics in X-BAT aircraft and ground vehicles. Own architecture, thermal, harnessing, and electro-mechanical design from concept through manufacturing, partnering with electrical, RF, PCB, reliability, supply chain, structures, and manufacturing teams to deliver flight-critical systems.

Lead thermal design, analysis, and integration for UAV avionics and custom power electronics. Develop and validate hand-calculation, CFD, and numerical models. Drive trade studies, test planning, instrumentation, and model correlation. Provide technical leadership, mentor junior engineers, and influence PCB/part selection and enclosure thermal designs to meet aerospace requirements.

Lead development and analysis of aerodynamic and structural load cases for an air vehicle. Perform maneuver, gust, landing, and ground loads (quasi-static and dynamic), aeroelastic stability checks, validate loads with FEA and flight test, coordinate across GNC/aero/structures, produce documentation, and improve loads methodologies and automation.

Lead design, analysis, and integration of avionics thermal management for unmanned aircraft. Develop and validate analytical, numerical, and CFD models, plan and run thermal tests, correlate data, advise PCBA and electrical design, and present technical findings while mentoring peers and driving robust thermal solutions.
