About The Position

Logos Space is developing a Low Earth Orbit (LEO) satellite system to provide resilient, high-performance satellite-based connectivity services to commercial enterprise and government users worldwide. The system is designed to extend cloud and data center network connectivity globally to fixed, seaborne, and airborne terminals, with speed and reliability as its foundation. The company is led by experienced engineers from the networking and satellite industries. The Product and Data Link Security team at Logos Space Engineering is crucial for ensuring network success by providing unique levels of security and authentication in space communications, supporting isolated flows and end-to-end encryption. This position is a key driver of the security architecture, involving extensive development efforts and collaboration with ground segment and spacecraft systems teams. The company seeks engineers who can thrive in a fast-moving environment and translate vague design ideas into concrete, testable architecture and secure solutions. The Platform Trust & Security Lead will specifically lead the security architecture for satellite onboard systems (bus + payload compute), focusing on designing secure boot chains, attestation mechanisms, and enforcing trust boundaries across all onboard components, requiring close collaboration with hardware, firmware, and system teams to ensure end-to-end platform integrity.

Requirements

• Bachelor's degree in Computer Science, Cybersecurity, or a related field (Master's degree preferred).
• Minimum of 7-10 years of experience in network security engineering, with demonstrable experience in designing and implementing security solutions for complex network environments.
• Strong knowledge of security principles, best practices, and frameworks (e.g. Zero Trust, defense-in-depth).
• Excellent analytical, problem-solving, and low-level debugging skills
• Ability to work independently and as part of a collaborative team in a fast-moving environment.
• Secure boot / chain of trust design
• Embedded systems (C/C++, Rust preferred exposure)
• Hardware Root of Trust (TPM, secure elements, eFuse)
• Firmware signing / attestation
• Low-level debugging & threat modeling

Nice To Haves

• Experience working with or understanding the unique security challenges and considerations of space-based communication systems.
• Knowledge of satellite networking concepts and protocols.
