• Collaborate with development teams to identify vulnerabilities, mitigate risks, and integrate security best practices throughout the software lifecycle.
• Lead the implementation of cloud security best practices — including authentication, security groups, PKI, and AWS security controls.
• Act as the primary security advisor, guiding engineering teams to design and deploy resilient, scalable, and secure cloud architectures.
• Champion a security-first mindset, upskilling teams and embedding security considerations at every stage of development.

• Strong experience in threat modelling, including identifying and addressing vulnerabilities in complex, cloud-based ecosystems.
• Excellent communication and collaboration skills to work cross-functionally with development and security teams.
• A passion for cybersecurity and innovation, ideal for someone eager to shape the future of connected vehicle security.
