About The Position

Planet’s Satellite Security team is the frontline defense for our global constellation. From the SuperDove to our next-gen Pelican and Tanager fleets, we ensure the integrity of the world’s most sophisticated Earth-imaging data. Our mission spans the entire lifecycle of a spacecraft: from hardware security partitioning and cryptographic key management to securing ground-to-space communications. As a member of the Satellite Security team, you will bridge the gap between embedded systems and cybersecurity. You’ll work alongside experts in Flight Software, FPGA, and Mission Operations to build the tools that protect our assets in orbit. This is a unique opportunity for an embedded engineer to pivot into security; we provide the specialized security training—you provide the engineering rigor. This is a full-time, hybrid role which will require you to work from our San Francisco office 3 days per week.

Requirements

Education: Bachelors’ in Computer Science, Computer Engineering, Electrical Engineering, or a related field
Experience: 2+ years of professional experience in Software Engineering, Embedded Systems, or Electrical Engineering.

Programming: Proficiency in C (for the hardware) and Python (for the tooling).
Communication: The ability to translate complex technical risks into actionable insights for satellite operators and project managers.
Version Control: Experience with Git, SVN, or similar workflows.

Nice To Haves

Prior exposure to cryptography/cryptology, network security, or basic penetration testing.
Experience in regulated industries such as Aerospace, Automotive, or Medical Devices.
