Build and operate full-stack applications, APIs, integrations, and event-driven data flows supporting product, manufacturing, and operations data. Model traceable domain records, lead projects from design through delivery, migrate systems, and implement observability and data-quality controls. Collaborate with engineering, supply chain, and manufacturing users, mentor engineers, contribute to technical designs, and participate in production support and incident response.

Design, analyze, build, and test propulsion systems for advanced satellites and missile defense vehicles from concept through flight. Lead propulsion development and ground test campaigns, review models and drawings, collaborate with multidisciplinary engineering teams, optimize system performance and manufacturability, and mentor engineers. The role requires expertise in rocket engines, valves, fluid systems, pressurization, propulsion testing, and vehicle-level checkouts, with occasional vendor and factory travel.

Design, analyze, build, and test propulsion systems for advanced spacecraft from concept through flight. Provide technical leadership and mentorship, review models and drawings, lead multidisciplinary design validation, support propulsion testing and vehicle checkouts, and present technical content to customers. The role requires extensive launch or space vehicle experience, fluid system expertise, and the ability to lead complex propulsion development in a fast-paced environment.

Leads the full lifecycle design and development of liquid rocket combustion devices, including injectors, thrust chambers, regenerative cooling circuits, nozzles, and acoustic stability features. Performs combustion, thermal, structural, and performance analysis; applies additive manufacturing and high-temperature materials; reviews CAD and GD&T drawings; interprets test data; supports build, integration, qualification, and flight delivery; and mentors engineers.

Leads propulsion analysis for liquid rocket engines and thrusters, developing engine cycle, injector, combustion stability, CFD, thermal-fluid, and regenerative cooling models. Partners with hardware designers and suppliers to validate models against hot-fire tests, guides design decisions, builds lightweight analysis tools, establishes analytical standards, and mentors propulsion engineers. The role supports development from concept through qualification and requires deep expertise in propulsion modeling and combustion dynamics.

Lead and support verification and validation testing for aerospace avionics components and subsystems. Responsibilities include board bring-up, hardware debugging, functional and electrical testing, automated test development, acceptance and environmental qualification testing, test data analysis, requirements traceability, documentation, and participation in technical reviews. Collaborate with hardware, software, and design teams to ensure components meet aerospace performance, reliability, and qualification standards.

Lead end-to-end motor control development for spacecraft mechanisms, including control algorithms, embedded firmware, drive electronics, architecture, testing, qualification, and on-orbit validation. The role supports gimbals, solar array drives, deployment mechanisms, and other precision actuation systems. Responsibilities include technical trade studies, component selection, spacecraft integration, troubleshooting, documentation, and mentoring while collaborating with mechanisms, avionics, GNC, and test teams.

Leads the design, electromagnetic modeling, testing, integration, and delivery of space-based antennas and RF front-end hardware. Performs full-wave simulations, antenna and array optimization, RF trade studies, spacecraft electromagnetic compatibility analysis, and measurement correlation. Collaborates cross-functionally on packaging, thermal, structural, manufacturing, and test challenges; leads technical reviews, mentors engineers, develops verification processes, and supports customer engagements. Requires deep antenna/RF expertise, advanced EM simulation skills, and experience taking complex engineering efforts from concept through qualification.

Lead avionics hardware and software integration, verification, validation, and system-level testing across spacecraft production and test platforms. Develop test plans, scripts, automation, and requirements traceability; troubleshoot hardware, software, and embedded systems; analyze results; and document compliance with aerospace standards. Collaborate across engineering teams and participate in design and test readiness reviews to ensure avionics flight readiness.
