About This Role

This role works across the company's AWS environment, strengthening cloud security, identity and privileged access management, detection, and incident response. You'll join the Security team, reporting to the Head of Cybersecurity and working closely with Engineering and DevOps, leading technical security projects, building controls and automation, and mentoring junior team members. Success in the first year means a stronger AWS security posture, faster and more consistent incident response, and security findings addressed proactively.
What You'll Be Doing
Strengthening security across AWS accounts, including account baselines, AWS Organizations, SCPs, and Control Tower guardrails.
Designing and implementing least privilege access, including IAM Identity Center, role-based access, and temporary privileged access to production.
Building and tuning detection and monitoring using CloudTrail, GuardDuty, Security Hub, AWS Config, VPC Flow Logs, and the company's SIEM.
Leading the technical response to AWS incidents, including investigation, containment, evidence collection, root cause analysis, and post-incident reviews.
Improving vulnerability and misconfiguration management, working with Engineering and DevOps to prioritize findings, resolve risks, and verify fixes.
Securing data, secrets, and credentials using KMS, Secrets Manager, encryption controls, and appropriate key management.
Building security into infrastructure as code and CI/CD pipelines through automated checks and policy enforcement.
Developing and maintaining technical security standards, runbooks, and incident response playbooks.
Sharing knowledge and mentoring 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.
Good 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.
Bonus Points
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.
