Senior Platform Firmware Engineer

This role sits at the boundary between hardware and software. You will work across platform firmware, FPGA logic, board bring-up, system management, and autonomous recovery systems to ensure reliable operation from first power-on through orbital deployment., * Develop and maintain platform firmware and board management infrastructure for advanced compute systems.

• Own system bring-up and low-level boot sequencing for custom hardware platforms.
• Design and implement FPGA/CPLD logic for power sequencing, reset orchestration, watchdog functionality, and telemetry.
• Develop and customize BMC firmware and management stacks using OpenBMC and related technologies.
• Implement and maintain platform management interfaces including Redfish and/or IPMI.
• Debug complex hardware/firmware interactions across CPUs, GPUs, PCIe fabrics, and networking devices.
• Collaborate closely with hardware, validation, thermal, and systems teams during bring-up and deployment.
• Develop fault recovery and autonomous reboot for remote orbital systems.
• Support secure boot, firmware update, and system attestation architectures., * Own critical hardware systems, not just a small component
• Fast iteration cycles with direct path from design to hardware testing
• Work closely across disciplines in a tightly integrated team
• High autonomy and ownership with real impact on the spacecraft
• Opportunity to help define hardware systems for a new class of space infrastructure

• Hands-on experience in Embedded systems, platform firmware, BMC development, or hardware bring-up engineering.
• Strong proficiency in C/C+ and Python.
• Deep understanding of platform initialization and boot architectures.
• Strong familiarity with hardware communication interfaces including I2C, SPI, UART, GPIO, and JTAG.
• Experience debugging hardware/software interactions at board and system level.
• Familiarity with FPGA or CPLD development workflows using Xilinx or Altera platforms.
• Strong systems-level debugging and problem-solving skills.

Preferred Qualifications

• Experience with server platforms, AI infrastructure, or high-performance compute systems.
• Familiarity with PCIe initialization and accelerator bring-up.
• Experience with remote management and fleet-scale telemetry systems.
• Knowledge of secure boot, attestation, and firmware security architectures.
• Familiarity with radiation-tolerant or fault-resilient system design.

The salary range for this position is $170,000 - $235,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity.

Cowboy Space Corporation is solving the global energy crisis by building the infrastructure for abundant, resilient space-based solar energy. We are tackling one of humanity’s most complex engineering challenges with a world-class team dedicated to delivering a revolutionary power platform. Cowboy Space Corporation is transforming how civilization powers, computes and connects - from orbit to Earth.

Background Cowboy Space Corporation is building the infrastructure to power and connect the orbital economy. Our modular, scalable satellites collect sunlight in Low Earth Orbit to enable multiple integrated applications: transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit high-performance computing clusters (GPU/TPU), and providing secure, high bandwidth optical data transport.

Current energy and data systems rely on complex logistics and outdated infrastructure. Cowboy Space Corporation overcomes these challenges by enabling direct, on-demand, secure, and scalable energy distribution and data processing from space. This will revolutionize how we operate in orbit and on Earth, supporting the rapidly expanding space industrial base, ISAM (In-Space Servicing, Assembly, and Manufacturing) operations, remote regions, and military bases.

Baiju Bhatt founded Cowboy Space Corporation in 2024. Inspired by his father’s work with NASA Langley Research Center, Baiju earned his B.S. in Physics and M.S. in Mathematics at Stanford before co-founding Robinhood, now a public company that has helped over 20 million Americans access the financial system. Cowboy Space Corporation has raised ~$365 million from Index Ventures, Interlagos, Construct Ventures, Breakthrough Energy Ventures, Andreessen Horowitz, NEA, and others.

This is an ambitious mission that demands extraordinary talent. Cowboy Space Corporation’s team has worked at places like SpaceX, Blue Origin, Stoke Space, Astranis and NASA, and is based in San Carlos, CA. If you’re ready to solve complex technical challenges and help build the most important energy company in the world, we want to hear from you.
