Software Engineer, HSM Infrastructure Security, Consumer Devices

In This Role, You Will

• Design and implement security-critical software and firmware for HSMs, secure elements, trusted execution environments, and hardware roots of trust.
• Build and harden the policy-to-HSM boundary responsible for authorizing certificate issuance and cryptographic signing operations.
• Develop HSM trusted applications, firmware components, host interfaces, device drivers, SDKs, or cryptographic service integrations.
• Implement or extend cryptographic interfaces such as PKCS#11, OpenSSL providers or engines, platform key-storage APIs, or comparable hardware-security interfaces.
• Build firmware and software that cryptographically enforces key generation, provisioning, usage, rotation, recovery, and destruction policies.
• Design and implement HSM-backed certificate authority, code-signing, key-management, and device-identity systems.
• Develop end-to-end cryptographic protocols spanning devices, secure hardware, policy services, and backend infrastructure.
• Build security capabilities supporting device attestation, secure boot, factory provisioning and restoration, user registration, and authentication.
• Design controls that make trusted software and policy changes verifiable, auditable, and subject to appropriate multi-party authorization.
• Write, review, test, and audit secure embedded software for resource-constrained environments.
• Develop test harnesses, emulators, fuzzers, and fault-injection tooling to validate security properties and failure behavior.
• Threat-model hardware and software trust boundaries and translate findings into concrete engineering improvements.
• Partner with hardware, firmware, infrastructure, application, and security teams to integrate secure-by-default capabilities into production systems.
• Help establish engineering standards for HSM development, applied cryptography, secure key management, and certificate infrastructure.
