Assess and interpret customer contracts for appropriate US GAAP accounting (ASC 606), support revenue recognition and milestone billing alignment, maintain technical accounting memoranda, assist month-end close and GL maintenance, reconcile contract-related balances, support audits, and partner cross-functionally to improve processes and ERP/financial system implementations.

Lead technical accounting for revenue recognition (ASC 606) by reviewing customer contracts, assessing billing milestones and accounts receivable timing, preparing technical memos, supporting monthly close and reconciliations, aiding audits, and partnering with Contracts, Program Management, and Billing to improve processes and ERP/financial systems.

Lead physics-based feasibility and mission architecture definition for orbital transfer vehicles. Rapidly iterate CONOPS, trajectories, and system-level trade studies; partner with BD and engineering; engage customers; identify and bound technical risks to ensure executable mission requirements.

Design, build, test, and integrate primary and secondary spacecraft structures and mechanisms from concept through launch. Own hardware development roadmap, perform calculations and FEA, produce drawings, generate test plans, work with manufacturing and cross-functional teams, and manage hardware maturity and documentation.

Develop and maintain high-fidelity physics-based simulations of space vehicle dynamics, sensors, actuators, and propulsion. Integrate simulations with HIL testbeds, validate models against test data, support system-level analysis, verification, and mission planning, and contribute simulation tools.

Lead propulsion component manufacturing from concept through prototype, qualification, and production. Develop assembly/test instructions, design fixtures and tooling, collaborate with design and shop teams, troubleshoot manufacturing/test issues, and expand in-house production and test capabilities to enable scalable, reliable propulsion hardware.

Design and implement end-to-end satellite communication modems from DSP blocks to network protocols, analyze timing and resource needs for RF products, build FPGA-SoC libraries, create test harnesses integrated into CI/CD, and collaborate with RF software engineers to deliver high-throughput FPGA blocks for space and ground systems.
