You will enjoy the flexibility to telecommute* from anywhere within the U.S. as you take on some tough challenges.

Primary Responsibilities:

• Provide limited, short-term operational support for the legacy HashiCorp Vault environment, focusing on stability, incident response, and "keep-the-lights-on" maintenance during its decommissioning phase
• Lead the migration of secrets and encryption workflows from HashiCorp Vault to AWS Secrets Manager and AWS Key Management Service (KMS), ensuring secure, efficient, and disruption-free transitions for application and infrastructure teams
• Design, build, and maintain secure CI/CD pipelines that integrate automated testing, security scanning, and policy enforcement for application and infrastructure changes
• Define and manage AWS infrastructure as code using Terraform, applying reusable modules and safe deployment practices for networking, compute, storage, and security resources
• Partner with the enterprise Compliance and Security teams to implement security initiatives across approximately 81 applications within the UHC Consumer Engineering organization, ensuring best practices are applied to improve security posture and compliance scores
• Execute security visibility objectives to raise MBO scores toward ≥90% targets, track progress and drive adoption of security controls across the portfolio
• Advance enterprise CI/CD security adoption by implementing required pipeline controls, enabling automated blocking of critical vulnerabilities, and achieving ≥95% adoption goals
• Automate security posture and vulnerability reporting to provide actionable insights for engineering teams and support internal governance requirements
• Collaborate with application, infrastructure, and security teams to design secure, observable AWS architectures for containerized and serverless workloads (ECS, Fargate, Lambda)
• Participate in the on-call rotation for DevSecOps tooling, responding to incidents and implementing improvements to strengthen security and reliability
• Contribute to enterprise AI initiatives by developing secure, compliant AI capabilities, helping shift the organization toward building AI solutions rather than solely consuming them

You'll be rewarded and recognized for your performance in an environment that will challenge you and give you clear directions on what it takes to succeed in your role as well as provide development for other roles you may be interested in.

• 2+ years of experience working with observability tools and methods for distributed systems, including structured logging, metrics, alerting, and troubleshooting, along with knowledge of identity and access control principles such as least privilege and role-based access
