Cybersecurity Engineer – RTOS Firmware
We seek an experienced Cybersecurity Engineer
to implement and integrate security features for our next-generation electric vehicle platforms.
In this role, you'll translate high-level security architecture into hands-on engineering solutions, tackling challenges across the vehicle ecosystem. By integrating security features directly into the ECUs and other critical systems, you'll be essential in bringing our security designs to life. Your skills will be crucial in developing, implementing, and validating security features across the platform.
The ideal candidate is passionate about automotive technology and security, and thrives in fast-paced, collaborative environments. You should have a strong background in embedded software development and excel at turning security requirements into robust, efficient implementations.
What you’ll do...
- Translate high-level security requirements and designs into practical, efficient implementations by developing and maintaining software components and libraries.
- Partner with each ECU team to effectively integrate security-focused software components into their codebases.
- Perform hands-on debugging and troubleshooting of security implementations, using low-level debugging tools to identify and fix issues.
- Conduct code reviews with a focus on identifying and addressing potential vulnerabilities in both newly developed and existing code.
- Collaborate with Verification & Validation teams to develop test plans to ensure robust, secure solutions.
- Provide technical support and troubleshooting for cybersecurity issues that arise during integration and testing.
- Stay current with emerging threats and vulnerabilities in automotive cybersecurity, proposing and implementing innovative solutions to address them.
- Contribute to building a strong security culture within the Advanced EV Development organization.
Required:
- 5+ years of experience in embedded systems development and cybersecurity implementation
- Comprehensive knowledge of embedded systems architecture and cybersecurity with proven experience applying this knowledge in automotive contexts.
- Proven expertise in embedded C programming, with a focus on secure coding practices.
- Python scripting
- Strong debugging skills and experience with embedded systems debugging tools.
- Solid grasp of automotive cybersecurity technologies and mechanisms in areas such as in-vehicle networking (e.g., LIN, CAN, Ethernet, wireless, UDS, XCP, TLS), hardware trust anchors (e.g. HSM, HSE, TEE, secure elements), secure boot, secure diagnostics, key management, and Over-The-Air (OTA) updates.
- Working knowledge of cryptography fundamentals, including symmetric and asymmetric algorithms, hashing, Public Key Infrastructure (PKI), and X.509 digital certificates, with experience applying these in automotive environments.
- Solid understanding of common security vulnerabilities and attack vectors in embedded systems.
- Experience in security testing methodologies and tools.
Desired:
- Broader automotive development expertise, which may include familiarity with AUTOSAR architecture, real-time operating systems (RTOS), functional safety concepts and their implementation (e.g., ISO 26262), and other automotive-specific development frameworks, standards, and methodologies.
- Previously lead the development of solutions for one or more of: secure boot, firmware signature verification, OTA, key management, and secure diagnostics.
- Familiarity with automotive cybersecurity standards and regulations (e.g., ISO/SAE 21434, UNECE WP29 R.155/R.156).
- Proficiency in additional programming languages such as Python or Rust
- Experience applying security principles and best practices in conventional cybersecurity domains including cloud infrastructure, Linux systems, or mobile platforms (e.g., Android).
