About the role
We're looking for a Battery Engineer to own the design, development, integration, and qualification of our spacecraft battery systems. You'll be responsible for developing reliable, high-performance energy storage solutions that power the spacecraft through eclipse periods, peak load events, and critical mission operations.
What they're looking for
- BS, MS, or PhD in Electrical Engineering, Mechanical Engineering, Materials Science, Chemical Engineering, or a related discipline
- 3+ years developing battery systems for aerospace, automotive, defense, or other high-reliability applications
- Experience designing battery packs and energy storage systems, including cell/module/pack architecture and electrical interconnect design
- Knowledge of lithium-ion battery chemistry (NMC, NCA, LFP), degradation mechanisms, and safety considerations
- Experience developing or integrating Battery Management Systems (BMS), including cell balancing, SOC/SOH estimation, and fault protection architectures
- Experience with battery testing, characterization, and validation, including cycle life testing, performance characterization across temperature, and abuse/safety testing

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Current energy and data systems rely on complex logistics and outdated infrastructure.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