Key responsibilities for this Principal Embedded Crypto Software Developer position:

• Specify and implement cryptographic algorithms across platforms, including Post-Quantum Cryptography (PQC).
• Design and specify software countermeasures against Side-Channel Analysis (SCA) and Fault Injection (FI) attacks.
• Provide technical leadership for cryptographic domains, driving architectural decisions and domain evolution.
• Collaborate with security architects, OS/firmware teams, and internal evaluation teams to ensure secure product integration.
• Drive product certification activities and support security evaluations.

Key requirements:

• 10+ years of industry experience in cryptography and embedded security.
• Strong implementation experience with cryptographic primitives — ECC, RSA, AES, SHA-2/SHA-3.
• Solid embedded software development skills in C and Assembly with strong knowledge of ARM Cortex-M and/or RISC-V microcontroller architecture.
• Knowledge of hardware and software countermeasures against SCA and fault-injection attacks.
• Experience in Post-Quantum Cryptography and/or Rust a plus.
• Strong debugging, analysis, and technical leadership skills.
