Top Tech Jobs & Startup Jobs

Develops and executes satellite integration, verification, and validation activities across Flatsat, HWIL, SWIL, and simulator environments. Responsibilities include requirements traceability, test planning, automated TCL scripting for TERMA CCS5, formal test conduction, troubleshooting, data analysis, and test reporting. Supports satellite architecture, CONOPS, interface documentation, and requirements development while coordinating multidisciplinary engineering activities.

Handles routine accounts payable and receivable, billing support, cash application, reconciliations, transaction processing, payroll accounting support, vendor and customer account maintenance, and payment recording. Prepares close, reporting, and tax support schedules; researches discrepancies; maintains accounting documentation; and supports aerospace and real estate accounting workflows across multiple entities.

Own administrative execution across Operations, including inbox management, onboarding and offboarding support, vendor coordination, records, office tasks, SOPs, trackers, and follow-up. The role supports multiple business functions, prioritizes recurring and special assignments, documents processes, escalates issues, and provides dependable administrative support in a primarily onsite, fast-growing environment.

Leads the full lifecycle development of satellite and aerospace software systems, including requirements definition, systems architecture, trade studies, verification, validation, testing, anomaly resolution, integration, deployment, and operations. Supports spacecraft product roadmaps, customization, cost optimization, and heritage-platform reuse. The role also leads multidisciplinary teams and performs specialized systems analyses across safety, reliability, security, certification, and related engineering disciplines.

Lead development of spacecraft Guidance, Navigation, and Control systems through full lifecycle: requirements, design, simulation, algorithms, flight software, and verification. Develop simulation tools, drive reuse of heritage Airbus products, support subsystem requirements and integration, and optimize designs for cost, manufacturability, and testing. Collaborate cross-functionally across spacecraft, payload, and launch integration activities.

Develop and maintain spacecraft flight software across the full lifecycle: requirements, design, implementation, testing, integration with HIL and flight hardware. Build tools and simulations, perform subsystem and platform-level tests, support anomaly resolution, systems modeling, and proposal efforts while collaborating with manufacturing and customers.

Lead development and operations of spacecraft navigation across all mission phases. Design and validate advanced Kalman filters and estimation approaches, own navigation products for reviews, support flight operations and anomaly response, mentor junior engineers, improve procedures and tools, and contribute navigation expertise to proposals and new concept development.

Develop, integrate, and test spacecraft flight software across the full lifecycle. Implement and upgrade cFS-based applications, perform unit-to-platform verification in simulation and HIL/FlatSat environments, support integration with hardware and payloads, and participate in anomaly resolution, mission operations support, and proposal activities.
