Core Responsibilities

Primary Functions

Conduct comprehensive Threat Analysis and Risk Assessments (TARA) on vehicle Electrical/Electronic (E/E) architectures, components, and connected features according to industry standards like ISO/SAE 21434.
Develop and maintain security-focused design requirements and cybersecurity concepts for new and existing vehicle platforms, translating high-level goals into actionable engineering tasks.
Identify, document, and model potential attack vectors, threat agents, and system vulnerabilities in complex automotive systems, including infotainment, telematics, powertrain, and ADAS.
Collaborate closely with hardware and software development teams to architect, design, and implement robust security controls and countermeasures for Electronic Control Units (ECUs).
Lead security-focused design reviews and architecture discussions, providing expert guidance on secure coding practices (e.g., CERT C/C++), cryptographic implementations, and secure boot processes.
Define, specify, and manage the implementation of cryptographic services, including key management, secure storage, and certificate handling for in-vehicle communication and external interfaces.
Design and integrate advanced security solutions such as Intrusion Detection and Prevention Systems (IDPS), hardware security modules (HSM), and secure onboard communication (SecOC) protocols.
Plan, execute, and thoroughly document penetration tests and vulnerability assessments on vehicle components, sub-systems, and the entire vehicle network (CAN, Automotive Ethernet, LIN).
Develop and utilize custom tools and scripts for specialized automotive security testing, fuzzing of proprietary protocols, and reverse engineering of embedded software and firmware.
Analyze findings from internal and external security tests, triage vulnerabilities based on calculated risk, and work directly with development teams to create and validate effective remediation plans.
Perform hardware-level security analysis, including side-channel analysis, fault injection, and board-level reverse engineering (e.g., JTAG/UART probing) to identify physical-layer vulnerabilities.
Act as a key technical resource for the Product Security Incident Response Team (PSIRT), performing deep-dive technical root cause analysis of security incidents and vulnerabilities discovered in the field.
Develop and manage security-related test cases and validation plans for critical lifecycle stages, including end-of-line (EoL) production programming and in-field vehicle software updates.
Continuously monitor the evolving threat landscape for automotive-specific threats and provide regular intelligence briefings and technical reports to engineering and management teams.
Drive the creation and enforcement of secure software development lifecycle (SSDLC) policies and procedures across the engineering organization to embed security from the start.
Serve as the primary cybersecurity interface for external Tier 1 and Tier 2 suppliers, meticulously reviewing their security designs and ensuring their deliverables meet our stringent security requirements.
Create and deliver impactful technical training sessions on secure design principles, automotive security threats, and defensive programming techniques for the broader engineering organization.
Author clear, concise, and detailed technical documentation, including security specifications, test reports, and risk assessment findings, for both technical and non-technical audiences.
Drive the automation of security testing and verification activities within our CI/CD pipelines to ensure security is continuously integrated, validated, and never an afterthought.
Participate actively in industry forums, working groups, and conferences (e.g., escar, Auto-ISAC) to stay current with state-of-the-art standards and best practices in automotive cybersecurity.

Secondary Functions

Support the Product Security Incident Response Team (PSIRT) by performing technical root cause analysis on field incidents.
Contribute to the organization's long-term cybersecurity strategy and technology roadmap.
Collaborate with IT security and cloud engineering teams to ensure end-to-end security from the vehicle to the cloud backend.
Participate in sprint planning, retrospectives, and other agile ceremonies as an integral member of a product development team.

Required Skills & Competencies

Hard Skills (Technical)

Deep understanding of embedded systems, microcontrollers (e.g., ARM, TriCore), and real-time operating systems (RTOS) like QNX, FreeRTOS, or Automotive Grade Linux.
Strong proficiency in programming languages commonly used in automotive and security, such as C/C++, and Python for scripting, tooling, and automation.
Hands-on experience with in-vehicle networking protocols, including CAN/CAN-FD, LIN, Automotive Ethernet, and diagnostic protocols like UDS (ISO 14229).
Practical, applied knowledge of cryptographic principles, including symmetric/asymmetric encryption, PKI, hashing, digital signatures, and hardware security modules (HSMs).
Verifiable experience performing Threat Analysis and Risk Assessment (TARA) and a strong familiarity with standards like ISO/SAE 21434 and regulations like UNECE WP.29 R155.
Demonstrated ability in penetration testing and vulnerability assessment, using tools like Kali Linux, Metasploit, Wireshark, CAN-utils, and various commercial or open-source fuzzing tools.
Familiarity with reverse engineering and binary analysis tools such as Ghidra, IDA Pro, or Radare2 for firmware and software analysis.
