Software Developer III

About the Opportunity

The Software Developer III will serve as a senior member of a small, high-trust team, assisting in building and operating the cloud platform behind a safety-of-life weather-warning system in a remote work environment. The platform runs on AWS with Kubernetes (EKS), a fully GitOps deployment model, and infrastructure defined entirely as code. The environment is FISMA-Moderate and is actively maturing toward a multi-account federal landing zone, placing this role at the intersection of platform engineering, security, and compliance. The team moves infrastructure through code and pipelines rather than tickets and manual console changes, and holds one another to that standard.

Success in this role looks like owning the whole path from a Terraform plan to a running, verified, signed workload.

What You Will Do in This Role

The Software Developer III will manage, operate, and secure the infrastructure, delivery pipelines, and compliance posture of a production AWS and EKS platform.

Responsibilities include:

• Manage Terraform for a multi-environment, multi-account AWS estate, including modules, state, and the safe reconciliation of live infrastructure into code.
• Operate Amazon EKS clusters, including networking, autoscaling, add-ons, workload identity, and cluster lifecycle.
• Run and extend the GitOps delivery model (ArgoCD), where a merge is a deployment, so the review gate and the verification loop matter.
• Build and harden CI/CD pipelines in GitLab, including security scanning, secrets detection, policy-as-code, container image scanning and signing, and the supporting evidence trail.
• Advance the platform's security and compliance posture against NIST 800-53, including least-privilege IAM, network isolation, continuous monitoring, and the artifacts that support an Authority to Operate.
• Help design the migration to a federal multi-account landing zone, including identity, cross-account networking, and promotion between environments.
• Perform other duties and responsibilities as assigned.

What You Will Bring

Required Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or a related field

• Experience with real-time data streaming in web applications
• Deep, hands-on Terraform experience, including writing reusable modules, managing remote state, and resolving drift between code and live infrastructure without disruption
• Experience operating Kubernetes/EKS at production scale, including workload identity (Pod Identity/IRSA), Helm, autoscaling, ingress, and load balancing
• Hands-on DevSecOps experience: security scanning (SAST, container, IaC, secrets), policy-as-code (OPA/conftest), and enforcing pipeline gates
• Working knowledge of a federal compliance framework (FISMA, NIST 800-53, RMF) and what it takes to support an ATO
