About Cowboy Space Corp:

Mission
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Current energy and data systems rely on complex logistics and outdated infrastructure.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.

The Role

This role is highly hands-on. You will own validation strategy and work across electrical, firmware, thermal, mechanical, and system software teams to uncover and resolve failure modes during launch and after orbital deployment.

Responsibilities

  • Lead board bring-up and system validation for advanced edge compute platforms.

  • Develop validation methodologies covering signal integrity, power integrity, power sequencing, thermal behavior, and system reliability.

  • Debug complex hardware and firmware interactions across High-speed interconnects (PCIe, Nvidia NVLink, AMD XGMI), memory subsystems, BMC/SMC and HMC architectures.

  • Perform detailed board analysis using oscilloscopes, logic analyzers, protocol analyzers, and power instrumentation.

  • Drive root-cause analysis for system failures discovered during validation and environmental testing.

  • Design and validate interfaces using protocols such as I2C, SPI, and UART.

  • Partner closely with mechanical, thermal, firmware, and software teams to ensure robust system integration.

  • Help define engineering standards and validation processes for flight-ready compute hardware.

Basic Qualifications

  • Bachelors degree in Electrical Engineering or a related discipline.

  • Experience in board design review, system validation, or compute hardware engineering.

  • 5+ years of experience designing and building compute hardware system

  • Strong background in server, accelerated compute, or embedded compute platforms.

  • Deep understanding of motherboard architecture, high-speed signaling, power delivery systems, and system management infrastructure.

  • Extensive hands-on debugging experience at board and system level.

  • Proficiency with lab equipment including oscilloscopes and protocol analyzers.

  • Experience with scripting or automation in Python, C/C++, or similar languages.

  • Strong ownership mentality and ability to independently drive technical problems to resolution.

  • Excellent communication and cross-functional collaboration skills.

Preferred Qualifications

  • 8+ years of experience designing and building compute hardware system

  • Experience with remote management technologies such as Redfish or IPMI.

  • Experience with spacecraft avionics, power systems, and thermal systems

  • Experience with environmental testing (vibe, thermal vacuum, EMI/EMC)

  • Radiation testing for LEO avionics background

  • Track record of ownership and leadership

Why this Role is Different

  • 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

Compensation and Benefits

The salary range for this position is $150,000 – $200,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity.

  • Equity in Cowboy Space Corp.

  • Employees and their eligible dependents may enroll in medical, dental, and vision insurance

  • 401(k) retirement savings plan

  • Paid time off

  • 10 paid holidays per calendar year

  • Paid parental leave

  • Relocation assistance if applicable

  • Daily lunch in the office and a fully stocked kitchen with beverages and snacks

ITAR Requirements

  • Export Control Requirement: To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR), applicants must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Cowboy Space Corporation

Cowboy Space Corporation is building a power grid in outer space for artificial intelligence. Using an integrated system of satellites and rockets, we will send high-performance compute and optical data transmission to Low Earth Orbit. Our constellation of satellites, Stampede, will harness abundant solar power to run on-orbit GPU data centers. With each launch, Stampede grows the power and compute capacity for humanity. Earth's energy grid can't run at the pace of AI. We can. AI is driving the largest infrastructure buildout in recent history, and the power grid on planet Earth can't keep pace. In major US markets, average grid connection lead times for new data centers can run 5-7 years or more. Meanwhile, AI demand is flat-out outgrowing Earth's pastures. Full-Stack Architecture: Traditional architecture treats the rocket as a workhorse and the satellite as freight. In our system, the rocket's upper stage is the satellite itself. It's a 1-megawatt data center with active thermal management and integrated compute, designed as one unified vehicle from the ground up. We trim the fat on redundant structure and avionics, dedicating every possible kilogram of compute to Low Earth Orbit. By owning our manufacturing and dedicated launch sites, we vertically integrate core technologies that enable deploying compute at scale. We’ve raised a $275M Series B at a $2B valuation led by Index Ventures, with participation from new investors IVP, Blossom Capital, and SAIC, alongside existing investors Breakthrough Energy Ventures, Construct Capital, Andreessen Horowitz, NEA, Interlagos and Baiju Bhatt.
