Top Tech Jobs & Startup Jobs in Los Angeles, CA

Lead end-to-end external aerodynamics CFD activities: geometry prep, meshing, solver setup, and post-processing in STAR-CCM+. Build automated simulation workflows (Java, Python), run CFD at scale on AWS, design aerodynamic geometry in CATIA, communicate trade-offs to airframe and GNC, and collaborate with structures and GNC teams.

Own and iterate a subsystem on solar-powered stratospheric aircraft from concept to flight: perform sizing and trade studies, build/test flight hardware and software, support integration/production/flight ops, and collaborate with avionics, GNC, power, RF, structures, and software teams in hands-on field and factory environments.

Drive end-to-end operational projects, improve cross-functional processes, build data capture and reporting, and lead high-priority special projects. Provide structured analysis for strategic decisions, operate deeply in business systems (ERP/HRIS), and project-manage stakeholders across Finance, Recruiting, People Ops, Business Development, and leadership to implement solutions in a fast-paced aerospace startup.

Develop and ship flight‑critical embedded firmware for long-endurance aircraft. Own embedded subsystems end-to-end including architecture, implementation, bring-up, debugging, test, and flight validation. Integrate sensors and peripherals, build drivers and middleware, design telemetry/logging, create HIL/test harnesses, and support production and flight operations.

Design, build, test, and fly lightweight, high-reliability structures and mechanical subsystems for stratospheric aircraft. Own subsystems from concept through flight, perform sizing and trade studies, iterate hardware rapidly, support integration/production/flight operations, and collaborate with avionics, GNC, power, RF, and software teams.

Design, implement, and flight-test end-to-end GNC systems for long-endurance stratospheric aircraft. Own modeling, simulation, state estimation, control law design, tuning, validation, HIL testing, and field integration with avionics, sensors, propulsion, and autonomy. Support production bring-up and desert flight operations.

Deploy, configure, and operate solar-powered aircraft and ground systems at test ranges and remote sites. Provide end-to-end field support, troubleshoot hardware/software/network issues in real time, execute flight tests, train operators, capture flight data and feedback, and update documentation and runbooks while collaborating with mechanical, GNC, RF, and software teams.

Design, build, integrate, and validate RF and communications systems for long-endurance stratospheric aircraft. Own RF subsystems end-to-end including link budgets, antenna selection, RF front ends, EMI/EMC mitigation, and field debugging using RF test equipment. Collaborate with avionics, GNC, electrical, mechanical, and software teams and support integration, production bring-up, and flight operations.

Lead manufacturing and production of flight hardware from prototype to scaled production. Design and improve build processes, tooling, work instructions, and quality checks. Partner with design engineers, drive root-cause analysis, support integration, testing, and flight operations, and help establish production capabilities in El Segundo.

Plan, oversee, and analyze flight test campaigns: design test cards and criteria, define instrumentation and telemetry, execute and monitor tests, adjust parameters in flight, build data pipelines, analyze telemetry for performance and anomalies, write test reports, and improve test processes. Travel to remote test sites and work in challenging field conditions.
