Senior People Operations Generalist

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

As Senior People Operations Partner, you will serve as the strategic and operational backbone of the People function for our growing Seattle office. Reporting directly to the Head of People, you will be a trusted partner and force multiplier — someone who can build structure where none exists, execute with precision, and keep the human element at the center of everything we do.

This is a rare opportunity to shape the people infrastructure of a company at an inflection point — scaling from 55 to 200+ employees — and to leave a lasting imprint on how Cowboy Space attracts, develops, and retains world-class talent.

This role is ideal for a seasoned HR professional who is equally comfortable building strategy and rolling up their sleeves to get things done.
