Senior Cyber Software Engineer

Job description

Job requirements

• You write production code, and we will evaluate you on it. Real fluency in C/C++, Rust, Golang, or Python — C or Rust strongly preferred for the firmware and cryptographic work — and the ability to read and modify the…
• 5-8 years of engineering experience with deep technical ownership of security-critical systems. Time spent primarily authoring policy, running scan tools, or coordinating artifacts will not substitute.
• Applied cryptography in practice rather than theory: you have implemented or integrated cryptographic libraries, handled keys and entropy correctly, and can explain how a device proves its identity at boot and how that…
• Low-level systems depth: the Linux kernel and userspace boundary, memory, filesystems, device drivers or firmware, and the ability to debug all of it with the tools you would expect — gdb, ftrace, and a logic analyzer…
• Experience assessing and hardening firmware, embedded, or cyber-physical systems, and a demonstrated understanding of how skilled adversaries attack them.
• Secure communications and network protocol work: TLS/PKI internals, tunneling, and what breaks in disconnected or degraded networks.
• Experience building and sustaining CI/CD systems; you treat pipelines and infrastructure as software, with version control, review, and tests.
• Working command of RMF and NIST 800-53 — enough to know exactly what an assessor needs and to automate producing it. You do not need to have been a full-time assessor.
