This is a hands-on engineering role focused on building and improving security capabilities across cloud infrastructure, DevOps environments, and detection systems.

• Improve security across cloud infrastructure and DevOps environments
• Work with engineering teams to strengthen DevSecOps and CI/CD pipeline security
• Improve software supply chain security (dependency scanning, container security)

• Partner with engineering teams to embed security practices into development and operational workflows
• Contribute to the evolution of security capabilities as the organisation grows

What You’ll Bring

• Several years of hands-on experience in security engineering
• Experience working across infrastructure, cloud, DevOps, or platform environments
• Experience in at least some of the following areas:
  • detection engineering (SIEM, EDR, building detections, alert tuning)
  • threat hunting and incident investigation
  • Cloud security (AWS or similar environments)
  • DevSecOps and CI/CD pipeline security
  • software supply chain security
• Ability to operate across multiple areas of security rather than focusing on a single niche
• Experience collaborating with engineering teams in product or platform environments
• Strong communication and cross-functional collaboration skills

Nice to have

• Experience working in crypto, Web3, or fintech environments
• Understanding of security threats specific to crypto or digital asset platforms
• Experience leading technical initiatives, projects, or small teams
• Experience working in startup or high-growth environments
• Background evolving from systems administration, infrastructure, or DevOps into security
