About the Job
We are seeking a Robotics Platform Security Engineer to serve as the lead architect for our security. This role is not about theoretical research; it is a high stakes, applied position centered on building a robust Root of Trust from the silicon up. You will be responsible for the "Base Layer" of our autonomous systems—architecting Secure Boot flows, managing hardware-backed cryptographic keys, and engineering hardened UNIX/Linux environments that can withstand both remote network attacks and direct physical tampering. Your mission is to ensure the robotic platform is a "Fortress OS" before a single line of mission-specific code is ever executed.
What You’ll Get To Do
Hardware Root of Trust & Secure Boot: Design and implement the end-to-end boot chain (from UEFI/Secure Boot to Measured Boot) to ensure the hardware validates every stage of the bootloader and kernel via TPM or Secure Elements.
Applied OS Hardening: Construct UNIX/Linux golden build images. This includes deep sysctl tuning, authoring custom AppArmor profiles, and stripping the kernel of non-essential drivers to eliminate lateral movement vectors.
Hardened Network Architecture: Engineer the robot’s security, utilizing mTLS for inter-process communication and configuring strictly scoped iptables/UFW policies to isolate sensitive control telemetry from external interfaces.
Security Orchestration (Python): Build a suite of Python tools to automate continuous security posture checks, including CIS Benchmark audits, automated certificate rotation, and real-time integrity monitoring via auditd.
Applied Vulnerability Research: Proactively identify and patch CVEs in the Linux ecosystem, using Python for automated fuzz testing of networking protocols and system interfaces.
What You Have
Applied System Mastery: Expert-level experience in Linux/UNIX administration and security hardening. You have a proven history of creating production-ready "Golden Images" compliant with STIG or CIS Benchmarks.
Hardware Security Expertise: Hands-on experience with TPM 2.0, Secure Elements (SE), and hardware-backed key storage. You understand the physical trust boundary of an embedded system and autonomous fleet.
Dual-Stack Programming: High proficiency in C/C++ for low-level system interactions and Python for building complex security automation and audit frameworks.
Network Defense: Deep knowledge of defensive networking, including VPN overlays, SSH hardening, and encrypted transport protocols (TLS/mTLS) for real-time systems.
Problem-Solving: The ability to conduct comprehensive threat modeling for robotic platforms, specifically identifying risks in the boot process and network-exposed interfaces.
The Extras That Set You Apart
Experience designing or implementing a complete secure boot and measured boot chain
Hands-on work with TPM backed disk encryption and remote attestation
Experience securing over-the-air (OTA) update systems
Deep familiarity with Linux boot internals (UEFI, GRUB, shim, UKI)
Experience hardening systems that operation in physically adversarial or untrusted environments
Strong understanding of network isolation and encryption
