Responsibilities

Analyzing System-on-a-Chip (SoC) security architectures to validate secure boot chains, root-of-trust enforcement, anti-rollback protections, and cryptographic controls at the silicon level

Validating hardware security requirements through hands-on testing of physical devices, evaluation boards, and chip samples across development and production lifecycles

Executing hardware security testing techniques, including fault injection attempts, debug interface probing (JTAG/BDM), and resistance validation against physical attacks

Reviewing schematics, board layouts, and hardware designs to ensure correct implementation of secure key storage, tamper mitigations, and debug access restrictions

Verifying manufacturing security processes by assessing secure provisioning flows, key injection procedures, and production lifecycle state transitions

Inspecting manufactured hardware samples to detect unauthorized component substitution, malicious modification, or deviations from approved security designs

Assessing cryptographic implementations (RSA, AES, HMAC, PQC) embedded in hardware and firmware to confirm secure key handling and isolation

Collaborating with silicon vendors, OEMs, and manufacturing partners to remediate security findings and validate corrective actions at the device and chip level

Identifying systemic hardware security risks by correlating lab results, manufacturing data, and field observations across large-scale device deployments

Documenting security assessments, validation outcomes, and risk mitigation plans in technical reports and communicating findings to engineering and leadership stakeholders
