About this role

The AWS Cloud Security Engineer will be responsible for building and maintaining a multi-account security foundation in AWS, implementing security standards, and managing AWS identity and access. The role involves designing secure connectivity between cloud and physical sites, threat detection and monitoring, and vulnerability management, all delivered as infrastructure as code. The engineer will work closely with IT and other teams to ensure security measures are effectively integrated and maintained.

Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of ON.energy as an employer.

What you need

  • 5+ years in cloud security, security-focused infrastructure, or cloud operations, with deep hands-on AWS
  • Production experience in multi-account AWS environments
  • Demonstrable command of attacker techniques and the detections and mitigations that counter them
  • Hybrid and site-to-cloud network security: segmentation, VPN, private connectivity, firewalls, routing, DNS, CIDR and subnetting
  • Strong AWS identity: roles, policies, permission sets, MFA, least privilege, access reviews; IAM Identity Center federated with an external IdP, ideally Microsoft Entra ID
  • AWS-native security services: GuardDuty, Detective, Security Hub, Inspector, Config, CloudTrail, KMS, WAF

Nice to have

  • Security experience in OT- or ICS-adjacent environments
  • Detection engineering and SIEM work; threat modelling; incident response you have personally run
  • Regulated or compliance-driven environments where access control, monitoring, and audit evidence are held to an external standard
  • Turning scanner output and audit findings into prioritized, actionable work for engineers who do not report to you
  • Troubleshooting security, identity, networking, and infrastructure issues across cloud and hybrid environments

What you get

  • Professional development and growth opportunities
  • Opportunity to grow with a mission-driven team shaping the future of clean energy

Worth weighing

  • No salary listed
  • Role involves significant hands-on work initially, which may not appeal to all candidates
  • Focus on infrastructure as code may require a strong coding background
  • Experience in OT or ICS environments is preferred but not mandatory
