As a Senior Security Engineer at Capco, you’ll lead the design and implementation of secure systems and processes across cloud and on-premise platforms. You’ll collaborate closely with engineering and client teams to embed security-by-design principles throughout the SDLC, integrate automated security tooling, and ensure resilience against evolving cyber threats. You’ll also use approved AI tools and AI-enabled workflows where appropriate to improve the speed, quality, and effectiveness of security engineering, while maintaining human judgement, responsible AI guardrails, and appropriate review and escalation.

- Collaborate across teams to champion secure development practices and responsible use of AI-enabled security workflows
- Lead vulnerability assessments, code reviews, and security audits across infrastructure and applications, maintaining appropriate human review, audit trails, and escalation pathways
- Develop and evolve security standards, engineering patterns, and data protection strategies
What We’re Looking For
- Strong hands-on experience with Palo Alto, Microsoft, or similar security ecosystems
- Deep understanding of cloud security for AWS, Azure, or GCP platforms
- Proven expertise in secure coding, endpoint protection, SIEM, and IAM
- Familiarity with frameworks and standards such as ISO 27001, NIST, and OWASP, alongside an understanding of responsible AI, security guardrails, and human-in-the-loop controls
- Proficiency in Python, Bash, PowerShell, or Go for security automation and tool development, with experience implementing Zero Trust Architecture solutions
