Define performance requirements, perform mechanism-level analysis, manage suppliers, develop test and qualification plans, and collaborate with optics, controls, and systems teams to deliver flight-qualified hardware.

Design, develop, and validate board-level RF hardware for free-space optical communications up to 50 Gbps. Own RF driver/receiver circuitry, high-speed RF/analog PCB layout, signal integrity analysis, simulation and lab characterization. Collaborate with optics, mechanical, firmware, and systems teams to integrate and flight-qualify RF/optical subsystems and support testing, troubleshooting, and documentation.

Design, develop, integrate, and qualify spacecraft battery systems from concept through flight. Responsibilities include pack/module architecture, BMS development (SOC/SOH, cell balancing, protections), cell chemistry selection, sizing and degradation modeling, thermal and safety strategies, environmental qualification and testing, manufacturing support, and on-orbit performance monitoring and failure investigation.

Design, operate, and secure on-premises and cloud IT systems in an ITAR/EAR environment. Manage identity, device management, networks, and cloud infrastructure; build automation and IaC; integrate telemetry into SIEM; enforce CIS baselines and export-control compliance; lead cross-functional initiatives and act as senior escalation above MSP.

Design, build, and qualify high-power fiber laser and amplifier systems and fiber-optic subsystems for space applications. Characterize lasers (linewidth, phase noise, RIN), model nonlinear effects, perform fiber splicing and assembly, design coherent receivers, and execute optical test plans and documentation for space qualification.

Lead design of high-voltage, high-power DC/DC conversion and distribution systems for terrestrial and orbital GPU compute.
