This role focuses on designing, building, and operating secure, repeatable AWS environments within a FedRAMP and ATO-governed context. The engineer will work in an environment where all deployments are infrastructure-as-code, peer-reviewed, and fully auditable. The successful candidate will combine hands-on AWS engineering depth with a strong sense of operational discipline, automation, and compliance awareness. This is not just EKS/Terraform build work; it is operational ownership across commercial and GovCloud AWS accounts for connectivity, routing, DNS, F5/load balancing, EKS, Terraform, security remediation, migrations, and stakeholder coordination. We are seeking dynamic, energetic, and engaging team members who love challenges! The ideal candidate will be able to align to the following duties: * Troubleshoot and support enterprise load-balancing and ingress patterns, including F5 or equivalent technologies, DNS, TLS/certificate paths, routing, and endpoint reachability. * Coordinate directly with application teams, Security, stakeholders, network owners, and program leadership to resolve connectivity, access, migraiton, and production readiness * Design, build, and maintain Infrastructure-as-Code using Terraform (modules, S3/DynamoDB remote state, OPA/tfsec policy integration). * Provision, upgrade, and manage EKS clusters, including namespaces, Helm-based add-ons (cert-manager, ESO, Confluent Operator), and IAM roles for service accounts. * Design, configure, and troubleshoot AWS VPC networking, including routing, TGWs, DNS, DHCP, endpoints, NACLs, and security groups. * Implement and secure microservices on EKS with proper connectivity to AWS services (S3, ECR, Secrets Manager, IAM). * Automate infrastructure deployments using GitHub Actions (or self-hosted runners), cross-account IAM role assumptions, and CI/CD policy gates. * Collaborate with security and applications teams to enforce least-privilege IAM, automate compliance evidence collection, and support RMF/ATO documentation. * Diagnose and resolve complex issues spanning containers, Kubernetes networking, and AWS layers (VPC - Zscaler - C-TIPS - SaaS endpoints). * Support observability, logging, and monitoring through integration with Elastic, ScienceLogic, or AppDynamics to meet SLA and audit requirements. * Mentor and guide junior engineers through knowledge sharing, paired engineering, and process standardization. * Evaluate and improve infrastructure design for policy compliance, resiliency, and performance tuning. * Develop and maintain SOPs and playbooks that align with program governance. * Support legacy-to-CAWS migration activities, including RabbitMQ/app-server connectivity, environment cutover support, dependency discovery, and validation of network paths across lower and production environments. * Quickly build working knowledge of inherited environments, document tribal knowledge, create diagrams/runbooks, and transfer operational context to primary and backup owners. * Operate within a formal change-control, evidence, and audit expectations, including CR support, implementation evidence, rollback planning, and post-change validation * Other duties, as assigned. ## Related Videos - [30 powerful AWS hacks in just 30 minutes: Boost your developer productivity](https://www.wearedevelopers.com/videos/1624-30-powerful-aws-hacks-in-just-30-minutes-boost-your-developer-productivity) - [An Applied Introduction to eBPF with Go](https://www.wearedevelopers.com/videos/1075-an-applied-introduction-to-ebpf-with-go) - [Tips and Tricks for Working with JSON](https://www.wearedevelopers.com/videos/1229-tips-and-tricks-for-working-with-json) - [CI/CD with Github Actions](https://www.wearedevelopers.com/videos/856-ci-cd-with-github-actions) - [Turning Container security up to 11 with Capabilities](https://www.wearedevelopers.com/videos/718-turning-container-security-up-to-11-with-capabilities) - [Introducing JSON Structure](https://www.wearedevelopers.com/videos/100219-introducing-json-structure) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence) - [What Makes WeAreDevelopers World Congress Different From Every Other Tech Event?](https://www.wearedevelopers.com/magazine/701-what-makes-wearedevelopers-world-congress-different-from-every-other-tech-event) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
