Jobs at CesiumAstro

Lead design, analysis, and testing of liquid rocket engine hardware and propulsion subsystems. Perform CAD design, CFD/FEA analyses, requirements definition, system integration, test program development, and technical documentation. Collaborate with mechanical, aerospace, and controls teams to deliver flight-ready hardware from concept through qualification.

Design, build, test, and troubleshoot flight engine electronics, circuit boards, avionics integration, sensors, and instrumentation. Lead wiring harnesses and avionics mounting, create schematics and drawings, execute test programs, analyze data, and collaborate with mechanical, aerospace, and controls teams to deliver flight-ready hardware.

Provide comprehensive legal and administrative support to the General Counsel, including drafting and redlining contracts and NDAs, managing contract records and e-signature workflows, supporting legal intake and knowledge management, conducting legal research, improving legal processes, partnering cross-functionally, and managing special projects.

Lead design and analysis of launch vehicle structures, interfaces, and payload accommodations. Perform structural and thermal FEA and transient analysis, develop and execute test programs, generate CAD models and technical documentation, collaborate with multidisciplinary teams, mentor engineers, and support mission operations and anomaly investigations.

Develop, port, and package embedded Linux applications and device drivers; customize kernels and bootloaders (U-Boot); maintain Yocto-based build system and CI/CD; perform board bring-up, system integration, testing, and customer-facing documentation; collaborate with hardware, firmware, systems, and FPGA engineers through product lifecycle to production and in-orbit support.

Design mechanical aspects of phased-array antennas and payloads from concept through flight: requirements, architecture trades, CAD/FEA, electronics packaging, thermal, mechanisms, manufacturing, testing, qualification, reviews, proposals, and in-orbit support.

Lead architecture and development of high-speed digital, DSP, and RF products for space and airborne platforms. Provide technical leadership for proposals, feasibility studies, SOW/requirements definition, make-vs-buy decisions, and technology transfers from R&D to production. Mentor cross-functional teams and support customer engagements throughout concept to deployment.

Lead end-to-end design of board-level power converters and power management for space/airborne systems: architecture, schematic and PCB design, modeling, simulation, testing, qualification, production transition, and mentoring junior engineers.

Lead end-to-end architecture of space and airborne ISR RF payloads (radar and RF sensing). Define antenna, RF front-end, digitization, beamforming, and system trade-offs. Drive concept development, support proposals, mentor engineers, and integrate architectures into mission requirements and product roadmaps.

Design and develop spacecraft power electronics across the full lifecycle: architecture, DC-DC converter design, simulation, PCB layout, verification, integration testing, and manufacturing support.

Lead structural and thermal design, analysis, and testing of launch vehicle components and systems from concept through flight. Perform static/transient FEA and thermal simulations, prepare CAD for analysis/manufacturing, develop and execute test programs, produce technical documentation for reviews, mentor engineers, and support mission operations and anomaly investigations.

Create and maintain MS Project schedules, support program scheduling and earned-value integration, develop reporting and scheduling protocols, support proposals and schedule margin management, and provide regular status reports to Program Management and Engineering leadership.

Lead design and development of power electronics for space/aerospace platforms across concept-to-production: DC-DC and point-of-load converters, magnetics, power systems, PCB layout, simulation, test, qualification, manufacturing support, and technical mentorship.

Customer-facing senior applications engineer supporting space communication products. Provide technical guidance, troubleshoot hardware/software anomalies, author application notes/manuals, transfer customer feedback to product teams, and support integration from marketing through in-orbit operations. Requires deep RF, FPGA, DSP, embedded software, and high-speed digital expertise.

Lead systems engineering for space-based communication payloads, developing architecture, requirements, CONOPS, risk mitigations, and subsystem designs. Serve as technical point of contact with customers and vendors, coordinate multidisciplinary teams, track milestones, resolve program issues, and drive continuous improvement across programs.

Lead and develop the Systems Engineering team for space communications products. Define and decompose requirements, CONOPS, V&V planning, risk assessment, customer interface, process development, resource deployment, mentoring, and technical leadership across programs.

Lead program performance and day-to-day execution for space subsystems or payloads. Serve as customer single point of contact, manage cost, schedule, technical performance, risk-based decisions, and program baselines. Create integrated master plans/schedules, WBS, and EVMS inputs; monitor progress and EACs. Collaborate with cross-functional teams, support process improvements, mentor staff, and manage multiple government/military customer programs.

Lead design and development of space-grade power electronics across the full lifecycle: architecture, detailed circuit design, simulation, PCB layout, verification, integration, production transition, testing, and mentoring. Drive trade studies, reliability analyses, verification plans, and lead a small engineering team to deliver high-reliability converters, inverters, and power systems for spacecraft.

Lead design, development, analysis, and testing of liquid rocket engine hardware and propulsion subsystems. Design parts (gimbals, bellows, pipelines), own requirements and system integration, perform CFD/FEA, develop and run test programs, generate technical documentation, and collaborate with mechanical, aerospace, and controls teams to deliver flight-ready hardware.

Design and develop various pneumo-hydraulic and electrohydraulic valves; own requirements, system-level integration, and architecture trades; perform CFD and FEA analyses; develop and execute test programs; generate technical documentation and participate in PDR/CDR; collaborate across mechanical, aerospace, and controls teams to deliver flight-ready hardware.
