ARX Robotics is seeking a Senior Cybersecurity Engineer to lead product security across the full lifecycle of autonomous ground systems. In this role, you will be the driving force behind security architecture and strategy, working side by side with software, systems, and cloud engineering teams to ensure resilient, trustworthy products built to withstand real-world threats.
You will shape how ARX builds products from the ground up, not review them after the fact. Key responsibilities include:
• Developing and maintaining a robust product security program with requirements, standards, and best practices that engineering teams can use
• Creating threat models and security risk assessments using methodologies such as STRIDE and ATT&CK
• Conducting security architecture reviews that identify risks early and feed practical mitigations into product design
• Building a DevSecOps culture by integrating automated security testing into CI/CD pipelines and championing secure-by-default principles
• Establishing secure supply chain practices, including evaluation of third-party components, open-source dependencies, and software bills of materials
• Implementing vulnerability management processes spanning internal triage, remediation tracking, and customer-facing disclosures
• Providing security guidance and training to raise the security bar across engineering teams
• Ensuring compliance with relevant frameworks including IEC 62443, EU Machinery Regulation 2023/1230, prEN 50742, NIST SP 800-82, and the Cyber Resilience Act (CRA) 2024/2847
ARX Robotics is a dual-use technology company specializing in autonomous unmanned systems and sensors for the European defence sector. The company develops unmanned ground systems and sensors that assist NATO Armies and civilian first responders in challenging operational environments. The team is expanding rapidly in a dynamic sector where collaboration and innovative problem-solving are core to the culture.
The company offers a competitive compensation package including bonus opportunity, 27 vacation days (increasing to 30 with tenure), employer-supported pension contribution, learning and development support, flexible benefits via Probonio, hybrid working setup, structured salary bands with levelling framework, referral bonuses, and relocation support where applicable.
REQUIREMENTS:
• 7+ years of experience in product security, application security, or secure software development, ideally within complex or regulated product environments
• Degree in Computer Science, Cybersecurity, Software Engineering, Electrical Engineering, or related field, or equivalent practical experience
• Solid command of secure development principles including authentication, authorization, encryption, secrets management, and secure communications
• Hands-on experience with security architecture reviews, threat modeling, and security testing methods (SAST, DAST, SCA, fuzzing, penetration testing)
• Practical experience with cloud-native applications, APIs, containers, and microservices
• Familiarity with defense, embedded, or operational technology security (secure boot, HSMs, firmware integrity, teleoperation system security)
• Strong communication skills to engage effectively with engineering teams, leadership, customers, and auditors
• Relevant security certifications (CSSLP, CISSP, GWAPT, or cloud security credentials) are a plus but not required
Note: Candidates do not need to meet every requirement to apply; motivated candidates eager to grow into the role are welcome.
