Top Tech Jobs & Startup Jobs in Seattle, WA

Design, simulate, and validate guidance, navigation, and control systems for an orbital-class launch vehicle. Develop 6-DOF dynamics simulations, implement control algorithms in Python/C++, analyze trajectories and dispersions, perform HIL and Monte Carlo testing, and support launch and mission operations.

Lead prediction and management of aerodynamic heating for launch vehicle ascent and re-entry. Run viscous, reacting-flow CFD, define aeroheating environments and boundary conditions, size TPS, manage aeroheating databases, plan and correlate ground/flight tests, and communicate results across multidisciplinary teams.

Own full-cycle recruiting for technical, manufacturing, operational, and business-critical roles. Source passive candidates, build pipelines, manage ATS hygiene, coordinate interviews, drive candidate experience, partner with hiring managers and leadership, and close competitive hires for deep‑tech and aerospace roles.

Lead development and analysis of launch and spacecraft trajectories, orbital propagation and station-keeping, mission design and contingency planning, flight dynamics simulation tooling, and cross-disciplinary systems investigations to validate guidance and control profiles.

Own onsite workplace operations and employee experience, coordinate onboarding and internship programs, support People operations and cross-functional logistics, ensure candidate and visitor hospitality, and improve People processes during rapid startup growth.

Lead design, development, and testing of payload flight software in Rust for attitude/pointing, command handling, telemetry, and data storage. Define architecture and coding conventions, implement FDIR, build automated test infrastructure (simulation/HIL), integrate with GNC/avionics/electrical teams, support integration, launch, and on-orbit ops, investigate anomalies, and mentor other engineers to achieve a near-term on-orbit demonstration.

Design and implement motor controls, embedded firmware, and closed-loop control for spacecraft fluid systems. Develop automated fill/drain/vent sequences, perform modeling and HIL testing, integrate sensors and actuators, create FDIR logic, and support integration, hot-fire testing, and anomaly investigation to deliver flight-ready control solutions.

Build and lead the Launch & Propulsion analysis organization: define analysis philosophy and margin policy; oversee structural, thermal, and CFD analyses; develop toolchain and automated workflows; correlate models with test/flight data; hire and grow the team; set documentation and V&V standards; coordinate with design, test, manufacturing, and assurance; and present substantiation at program milestones.

Lead end-to-end mechanical design and manufacturing for TCA rocket engine components. Drive DFM-focused design, tooling and fixture creation, implement advanced fabrication (additive, CNC, EDM, specialized joining), develop process parameters, and plan/execute hotfire test campaigns with analysis and rapid redesign for flight qualification.

Lead design, analysis, testing, and manufacturing integration for the vehicle primary structures (airframe, tanks, thrust structure, interstages). Optimize for minimum mass, strength, stiffness, fatigue, thermal resilience, and rapid reuse. Drive FEA and hand calculations, execute structural test campaigns, close failure modes through rapid design-test-learn cycles, and support flight operations and refurbishment.
