• Apply Infrastructure as Code (IaC) practices using Terraform, including multi-stack environments, private module registries, and PR-gated plan/apply workflows.
• Instrument and monitor test and infrastructure environments using OpenTelemetry and Datadog.
• Identify and address performance regressions and infrastructure failures early.
• Build new automated coverage and end-to-end testing layers where they do not yet exist.
• Contribute as a full member of a Delinea sprint team, participating in architecture, design, and development.
• Promote secure development and testing practices using OWASP principles.
• Contribute to and improve shared testing frameworks, tools, and techniques across Platform teams.
