Own and build Catalyx’s marketing and communications function, including campaign strategy, content creation, channel management, team leadership, agency coordination, positioning, technical storytelling, KPI tracking, reporting, and marketing systems. Partner with founders, the COO, engineering, customers, investors, and commercial teams to support go-to-market, fundraising, and business growth. Translate complex space-tech, defense, and aerospace concepts into clear, compelling narratives.

Designs and qualifies spacecraft avionics hardware, including schematics, PCB layouts, component selection, simulations, testing, and documentation. The role covers OBC, power, communications, ADCS, and payload interfaces; FMECA and reliability analysis; space-grade component procurement; environmental and EMI/EMC testing; design reviews; and hardware-software integration. Collaboration with mechanical, thermal, and software teams is required to deliver reliable, standards-compliant mission hardware.

Designs, integrates, tests, and maintains satellite ground station infrastructure, including antenna rotators, RF hardware, control software, embedded systems, and cloud data pipelines. The role supports telemetry transfer, frequency coordination, regulatory licensing, FMECA, component procurement, documentation, and remote ground station operations.

Lead propulsion architecture and hardware development from concept through qualification and flight-system integration. Responsibilities include valve development, COPV design and validation, tank and plumbing requirements, propulsion testing, sensor selection, material trade-offs, and directing the propulsion team. The role requires aerospace or mechanical engineering expertise, fluid systems experience, SolidWorks proficiency, CFD knowledge, and hardware project leadership.

Design, simulate, implement, and validate attitude determination and control systems for nanosatellites and CubeSats. Responsibilities include developing estimation filters and control algorithms, integrating sensors and actuators, implementing onboard firmware, conducting HIL/SIL testing, performing FMECA, analyzing telemetry, tuning post-launch parameters, coordinating with mission teams, sourcing components, and maintaining technical documentation.

Design, develop, and validate embedded software for satellite flight computers and subsystem controllers. Responsibilities include low-level driver development, real-time scheduling, fault detection, redundancy, hardware bring-up, avionics integration, satellite communications, and SITL/HIL testing. The role requires C/C++ expertise, bare-metal and RTOS programming, FPGA integration, embedded debugging, automated testing, and knowledge of reliable aerospace systems.

Designs high-speed digital and RF printed circuit boards for satellite and communications systems. Responsibilities include FPGA breakout, BGA fanout, RF layout, controlled-impedance routing, power distribution, decoupling, schematic design, simulation, documentation, and board revision management. Collaborates with system architects, RF engineers, embedded teams, and test personnel while supporting mission-critical aerospace and defense-grade electronics.

Lead the design and development of spacecraft electrical power systems across the full lifecycle. Responsibilities include power budgeting, EPS architecture, schematics, PCB layouts, component selection, power analysis, MPPT and battery algorithms, reliability assessments, procurement, subsystem integration, environmental testing, documentation, and in-orbit operations support.
