• ...And soon we’ll be expanding across the US & Europe

Why this role is exciting

As a Principal/Senior Security Engineer , you will play a critical role in shaping the cybersecurity foundation of Vay’s vehicle and remote driving ecosystem. This is a highly cross-functional role that sits at the intersection of automotive security, embedded systems, safety-critical development, and organizational leadership.

You’ll work closely cross-functionally to ensure our products are designed, developed, and validated with security at the core. Your work will directly influence how we assess risk, define mitigations, validate security requirements, and scale secure engineering practices across the company.

This role is ideal for someone who can operate both strategically and hands-on. You should be comfortable driving high-level security architecture and process discussions while also diving deep into technical details when needed. Strong communication and stakeholder management skills are essential, as you’ll often act as the security voice across the organization.

What you'll be driving

You will lead and evolve the cybersecurity engineering practices that support Vay’s remote driving technology and vehicle platforms. In order to do that, you will:

• Develop, define, and maintain cybersecurity processes aligned with ISO 21434 and other relevant standards and frameworks such as ISO 27001 and UNECE R155/R156
• Perform security risk assessments and maintain the Threat Analysis and Risk Assessment (TARA) work products
• Define cybersecurity requirements and collaborate with cross-functional engineering teams to implement effective mitigations
• Partner with Safety, Systems, Embedded, and Validation teams to ensure secure product development throughout the lifecycle
• Drive security architecture discussions and influence system-level design decisions across multiple domains
• Create and evolve security testing and validation strategies for vehicle and remote driving systems
• Support secure OTA update mechanisms and secure communication architectures
• Represent cybersecurity topics in internal and external technical discussions and reviews
• Help build scalable security processes that support the growth of Vay’s commercial fleet and technology platform

This might be a great fit, if

You are an experienced security engineer working closely with software, firmware, platform, and systems engineering teams to influence secure product design across the development lifecycle:

• Around 8+ years of experience in cybersecurity engineering
• Experience building or securing embedded products within robotics, medical devices, industrial automation, IoT, automotive, aerospace, telecommunications, or other safety-critical industries.
• Strong understanding of embedded product security principles, secure system architecture, embedded networking, secure software updates, and device lifecycle security.
• Experience performing security risk assessments, threat modelling, or equivalent security analyses for embedded products.
• Familiarity with security standards or regulatory frameworks relevant to embedded products (for example ISO 21434, IEC 62443, IEC 62304, Common Criteria, CRA, or similar).
• Strong understanding of embedded systems, embedded Linux, firmware, and secure software development practices.
• Knowledge of cryptographic concepts and secure communication principles
• Ability to assess security vulnerabilities, prioritize risks, and define practical mitigations
• Excellent communication, planning, and stakeholder management skills
• Comfortable operating both strategically and hands-on in fast-moving engineering environments
