Nice to Have

Skills & Experience:

• Experience supporting embedded firmware platforms, board support package development, secure boot, secure storage, cryptographic services, or firmware update mechanisms.
• Experience in one or more of the following areas: bootloaders, embedded file systems, Linux, CAN Bus, Modbus RTU, Modbus TCP, network security, device identity, or certificate management.
• Experience with Agile development methodologies and integrating security activities into sprint planning, backlog management, release readiness, and defect triage.
• Initiative and ability to work independently and as a member of a multi-disciplinary team while managing multiple security, development, or remediation priorities.
• Strong communication skills, both verbal and written, with the ability to clearly explain technical security risks, remediation plans, and release impacts to technical and non-technical stakeholders.

Job Description:

What You Will Do:

• Partner with stakeholders, product teams, and security teams to define secure system requirements for embedded firmware, IoT edge devices, gateways, and backend-connected components.
• Design, develop, and test secure firmware and IoT software using secure-by-design principles, including authentication, authorization, secure communications, encryption, logging, and secure update mechanisms.
• Implement hardware security controls including secure elements, TPMs, hardware root of trust, and JTAG/SWD lockdown.
• Apply memory safety practices and compiler hardening techniques to mitigate common C/C++ vulnerabilities.
• Develop secure device provisioning workflows including key injection, certificate enrollment, and device identity lifecycle management.
• Integrate secure cloud to device communication patterns such as mutual TLS, token based authentication, certificate rotation, and secure onboarding using cloud to device security.
• Lead vulnerability triage, root-cause analysis, remediation planning, patch development, verification, and release coordination for embedded and IoT software components.
• Perform and support threat modeling, secure code reviews, static and dynamic analysis, dependency scanning, and security testing throughout the software development lifecycle.
• Participate in embedded incident response, coordinated disclosure, and rapid hotfix development for fielded devices.
• Design and implement secure OTA update pipelines including signing, encryption, rollback protection, A/B partitioning, and update integrity validation using secure OTA lifecycle best practices.
• Integrate SAST, DAST, dependency scanning, and firmware specific security checks into CI/CD pipelines using secure CI/CD pipelines principles.
• Collaborate with cross-functional teams, including hardware, software, product management, quality, regulatory, and external partners, to deliver secure connected products.
• Stay current with cybersecurity standards, secure development practices, emerging vulnerabilities, tools, and techniques relevant to embedded systems and industrial IoT environments.
