Senior Expert, Embedded Software Security & Security Architectures

YOUR ROLE

We are seeking a Senior Expert in Embedded Software Security and Security Architectures to define, oversee, and strengthen all software security development activities for the RFOC subgroup products across automotive and non-automotive markets.

This role is responsible for leading security‑by‑design practices throughout the software lifecycle, from requirements definition through design, implementation, integration, validation, and release support.

The ideal candidate combines deep expertise in embedded software development, cybersecurity standards, secure coding, and security architecture, with the ability to guide engineering teams and collaborate effectively with quality, project management, and product stakeholders.

The position requires a strong background in automotive quality processes such as ASPICE, knowledge of ISO/SAE 21434 and cybersecurity requirements for automotive products as well as Common Criteria and SESIP for IT and Io T applications.

It has to support internal and external audits related to security, quality, and process compliance.

Prepare and provide evidence, documentation, and technical justification during reviews and audits.

It is key the ability to operate effectively in complex, fast‑paced, and demanding development environments.

• Security Leadership and Architecture
• Define and supervise the software security strategy for RFOC subgroup products.
• Lead the design of secure embedded software architectures for automotive and non-automotive applications.
• Establish security requirements, security controls, and architectural principles aligned with product and market needs.
• Review and approve security‑related design decisions, ensuring compliance with internal standards and external regulations.
• Support threat analysis, risk assessment, and security concept activities for embedded systems.
• End-to-End Security Development Oversight
• Drive software security activities across the full development lifecycle: requirements management, architecture, detailed design, implementation, integration, verification and testing.
• Ensure security features are implemented consistently and robustly across software components.
• Guide engineering teams in adopting secure development practices and maintaining traceability from security requirements to validation evidence.
• Secure Coding and Secure Development Practices
• Promote and enforce secure coding practices across embedded software teams.
• Perform or lead secure code reviews, vulnerability assessments, and remediation planning.
• Define security development guidelines, coding rules, and defensive programming practices.
• Contribute to the analysis and mitigation of software vulnerabilities and security weaknesses.
• Team Guidance and Cross-Functional Collaboration
• Work closely with software engineering teams to drive execution and quality across security‑related activities.
• Provide technical leadership and coaching to engineers involved in security requirements, design, implementation, integration, and testing.
• Collaborate with project management, quality assurance, product management, system engineering, and other stakeholders.
• Help teams make practical, risk‑based decisions when ideal solutions are constrained by technical, timing, cost, or program realities.
• Program Execution in Complex Environments
• Adapt to changing priorities, evolving planning, and shifting technical constraints.
• Sustain performance during workload peaks and operate effectively under pressure in large and challenging projects.
• Manage trade‑offs and compromises while preserving security integrity as much as possible.
• Support issue resolution and escalation management for security‑related risks and execution blockers.
• Innovation and Continuous Improvement
• Stay current with emerging trends in embedded security, automotive cybersecurity, and secure development methodologies.
• Champion innovation in development workflows, including the use of AI‑driven tools and methodologies to improve productivity, quality, and efficiency.
• Identify opportunities to simplify processes, automate repetitive tasks, and improve the effectiveness of security engineering practices.
• Contribute to continuous improvement of tools, methods, templates, and best practices.
• YOUR SKILLS & EXPERIENCES

Experience
