The Woven Planet Vehicle Security Team is responsible for the cyber security of the vehicle products that include a highly programmable vehicle software development ecosystem.

Modern cars are an IoT device running complex, safety-critical software. Yet, their architecture has remained fundamentally unchanged for decades. What if we have an opportunity to redesign it with a software-first approach for all future Toyota cars and build an open software ecosystem with an abstraction layer so developers across the world can build software and services for autonomy, mobility, user experience and the connectivity of vehicles and physical infrastructure, with modern software tooling?

The Woven Planet Vehicle Security team is looking for exceptional product security engineers who will work on the new vehicle architecture and the software ecosystem. 

You will analyze vehicle software platform system architecture: operating systems, networks and applications, and the underlying components (SoC, ECU) from a security perspective. You will be expected to be skilled at discovering gaps in our programs, discovering security issues, and driving solutions with cross-functional partners.

You will lead and influence security architecture, risk analysis, vulnerability testing, and security reviews for vehicle products across Woven Planet cross functional teams.

・Assist development teams in architecting and securing the new software and hardware ecosystem 
・Evaluate the security of operating systems, libraries, and protocols for embedded systems
・Lead threat modeling towards components of the hardware abstraction layer, service layer, runtime environment and application layer
・Audit embedded and application code to identify and patch security vulnerabilities
・Identify security issues and risks, and develop mitigation plans
・Provide tools to implement the reference architecture
・Evaluate and recommend new and emerging security products and technologies

・Bachelor’s degree in Computer Science, Computer Engineering or related field, or 10+ years relevant work experience
・7+ years of experience in software development
・3+ years of experience in software security as an architect or a developer of security solutions
・Advanced knowledge of the following domains: security engineering, system and network security, authentication and security protocols, cryptography, operating system and application security
・Security expertise in one or more of:
   ・Implementation of multilayered independent levels of security (MILS) architecture for high-assurance embedded systems
   ・Virtual machine and hypervisor (VMM) security
   ・Operating system (OS) security
   ・Security of real time operating systems (RTOS)
   ・Implementation and configuration of security modules (LSM) in Linux
   ・Security of components of compile time and runtime environment (RTE)
・Practical experience of development of libraries (C/C++) for software security 
・Knowledge of DevSecOps methodology and components of a secure SDLC
・Experience with secure operating systems architecture, security design, and threat modeling
・Familiarity with maturity models such as BSIMM or OpenSAMM
・Strong communication skills in English (both written and spoken)




  • Experience in development of software components for automotive systems or robots
  • Experience in development of hardware abstraction layer (HAL) components
  • Experience in development of real-time operating systems (RTOS)
  • In-depth knowledge of Unix-like operating systems and their security components, preferable – used in automotive industry (e.g. Automotive Grade Linux)
  • Professional experience in kernel and hypervisor security 
  • Understanding of standards such as ISO 21434 and ISO 26262 
  • Ability to communicate in Japanese is a plus
