About the Role

We’re looking for an experienced security engineer who enjoys solving complex problems and turning security priorities into practical improvements. You’ll work across our AWS environment, strengthening cloud security, identity and privileged access, detection and incident response.

You’ll join the Security team, reporting to the Head of Cybersecurity and working closely with Engineering and DevOps. You’ll lead technical security projects, build controls and automation, and mentor junior team members. Success in your first year means a stronger AWS security posture, faster and more consistent incident response, and security findings addressed proactively.

What You’ll Do

• Strengthen security across our AWS accounts, including account baselines, AWS Organizations, SCPs and Control Tower guardrails.
• Design and implement least privilege access, including IAM Identity Center, access based on roles and temporary privileged access to production.
• Build and tune detection and monitoring using CloudTrail, GuardDuty, Security Hub, AWS Config, VPC Flow Logs and our SIEM.
• Lead the technical response to AWS incidents, including investigation, containment, evidence collection, root cause analysis and post incident reviews.
• Improve vulnerability and misconfiguration management, working with Engineering and DevOps to prioritize findings, resolve risks and verify fixes.
• Secure data, secrets and credentials using KMS, Secrets Manager, encryption controls and appropriate key management.
• Build security into infrastructure as code and CI/CD pipelines through automated checks and policy enforcement.
• Develop and maintain technical security standards, runbooks and incident response playbooks.
• Share your knowledge and mentor junior engineers as the team grows.

What We’re Looking For

• At least 5 years of experience in security engineering or a related technical role, including at least 2 years securing production AWS environments.
• Strong practical knowledge of AWS security, including IAM policies, SCPs, network security, KMS and native detection services.
• Practical understanding of container and Kubernetes security, particularly EKS.
• Experience investigating cloud security incidents and making sound decisions under pressure.
• Experience with infrastructure as code, preferably Terraform, and automation using Python or a similar language.
• Experience building SIEM detections and alerting, investigating events and reducing unnecessary noise.
• The judgment to prioritize meaningful risks and work with engineering teams to deliver practical fixes.
• Clear written and spoken English, with the ability to explain technical findings to engineers, leadership and other stakeholders.

Nice to Have

• AWS Certified Security - Specialty or certifications such as GCIH, GCFA or OSCP.
• Experience in fintech, digital assets or another regulated financial services environment.
• Experience with wallet infrastructure, smart contract security or key management using HSMs.
