Principal Platform Reliability & Security Engineer

• Own the AWS estate end to end, including ECS, RDS, networking, and infrastructure provisioned through

Terraform.

• Build and maintain GitHub Actions pipelines to build, test, and promote code from UAT to production, with

deployment gates and reliable rollback strategies.

• Define and run versioning, release testing, and rollout processes across shared, dedicated, on-premise, and air-

gapped customer environments.

• Monitor production, respond to incidents and after-hours alerts, and resolve L2 escalations that L1 support

cannot address. Improve reliability to prevent repeat failures.

• Run vulnerability scanning across dependencies, containers, and code; assess CVE relevance and prioritize

remediation. Own secrets, access controls, container hardening, and key rotation.

• Lead technical responses to customer security due diligence, explaining implemented controls and documenting

incident response procedures.

• Own backups and disaster recovery for every customer environment, including recovery approaches for on-

premise and air-gapped deployments without cloud access.

• Track and optimize cloud spend through right-sizing, cost visibility, and early detection of unexpected usage;

explain infrastructure costs and their drivers.

rollback strategies.

• Working application security knowledge covering dependency scanning, secret management, container

hardening, and practical CVE assessment.
