The Opportunity

Strategic Business Systems (SBS) is expanding our AWS Professional Services team to support a high-priority, mission-critical national security program. We are actively building out secure cloud environments in AWS classified regions and are looking for engineers to help design and stand up the foundational infrastructure.

This role is focused on building and scaling AWS Landing Zones in highly secure environments. You'll be working directly with AWS teams and mission stakeholders to establish the core cloud architecture that future applications and capabilities will depend on.

* Build out core cloud infrastructure including account structure, networking, IAM, and guardrails

* Establish secure, scalable multi-account architectures aligned to mission requirements

* Implement infrastructure as code using Terraform and/or AWS-native tools

* Configure and manage VPCs, subnets, routing, DNS, and connectivity patterns

* Deploy and enforce security controls, logging, and monitoring frameworks

* Support integration with enterprise identity, access control, and compliance requirements

* Partner with AWS and customer teams to ensure alignment with best practices

What We're Looking For

AWS Infrastructure & Architecture

* Hands-on experience building AWS environments from the ground up

* Strong understanding of Landing Zone concepts (Control Tower or custom implementations)

* Experience designing multi-account AWS architectures

Networking

* Deep understanding of AWS networking (VPCs, routing, NAT, Transit Gateway, Private Link, etc.)

* Experience designing secure connectivity patterns in restricted environments

Automation / IaC

* Experience with Terraform, Cloud Formation, or similar IaC tools

* Ability to automate infrastructure deployment and configuration

Security & Compliance

* Experience implementing secure cloud environments (IAM, ABAC, logging, guardrails)

* Familiarity with operating in classified or highly regulated environments

Nice to Have

* Experience working in AWS Gov Cloud or classified regions

* Familiarity with DISA STIGs, NIST, or DoD cloud requirements

* Experience supporting ATO or compliance-driven environments
