At the heart of Defining Possible is our commitment to missions. In rapidly changing global security environments, Northrop Grumman brings informed insights and secure technological solutions to enable strategic objectives. We’re looking for innovators who can help us keep building on our wide portfolio of secure, affordable, integrated, and multi-domain systems and technologies that fuel those missions. By joining in our shared mission, we will support yours by expanding your personal network and developing skills, whether you are new to the field or an industry thought leader. At Northrop Grumman, you will have the resources, support, and team to do some of the best work of your career.

Northrop Grumman’s Corporate Sector's Chief Information & Digital Office (CIDO) is seeking a Sr. Principal Computer Systems Analyst - Cloud Platform / Landing Zone Engineer (AWS) tosupport its IT Infrastructure & Operations organization's Classified Solutions team.The selected candidate will serve as the leading technical authority for our proprietary, air-gapped AWS Secret Cloud for Industry (ASCI) IL6 multi-account environment. This technical leader will guide the successful design, security standards, and architectural integrity of classified multi-account workloads.

This role is responsible for the transition from legacy “on-prem” operational habits to automated, highly resilient cloud-native infrastructures, ensuring that developers receive modern, high velocity capabilities without compromising our Authorization to Operate (ATO). You will apply extensive technical expertise to solve complex, non-recurring deployment challenges and serving as a key mentor for junior platform personnel and tier-1 triage teams.

The selected candidate will be required to work on-site, full-time at our Redondo Beach, CA, or Rolling Meadows, IL, or Melbourne, FL location.

The responsibilities of this role include, but are not limited to, the following:

General Responsibilities:

• Perform as a lead Sr. Principal Computer Systems Analyst - Cloud Platform / Landing Zone Engineer (AWS) in support of classified government contracts.
• Communicate effectively with all organizational levels, internal/external customers, vendors, and senior leadership, both verbally and in writing.

• Oversee operations and administration of multi-user computer systems and multiple networks, coordinating with IT teams, project managers, and end users.
• Analyze requirements, recommend, and implement hardware/software solutions; interact with vendors to evaluate and troubleshoot products and services.
• Define, implement, and maintain enterprise-wide system enhancements, including installation, upgrades/patches, monitoring, configuration management, and problem resolution.
• Lead testing, validation, and change management for major product releases across platforms.
• Develop, publish, and continuously improve technical standards and SOPs.
• Ensure compliance with Information Systems security guidelines; prepare and maintain security documentation, audit logs, and Assessment & Authorization (A&A) submissions; serve as senior liaison to the ISSM.
• Report on strategic initiatives and project status to executive stakeholders; act as a key technical advisor impacting enterprise-wide, mission-critical systems.

• Acts as a key technical advisor to senior leadership; impacts multiple programs and mission‑critical systems across the enterprise.
• Provide senior-level technical expertise by mentoring junior and experienced team members, fostering their professional growth and enhancing team capabilities.
• Lifts and moves equipment up to 50 pounds. 
• Work after hours, and weekends, as needed.

Environment Automation & IaC:

• Declarative Infrastructure: Develop and maintain declarative Infrastructure as Code (IaC) templates using declarative tools such as AWS CloudFormation, AWS SAM, Terraform, OpenTofu to standardize and automate Secret‑level cloud environments.
• Account Provisioning: Design and manage automated Account Vending Machines (AVMs) and account factories to rapidly provision standardized, compliant VPCs and AWS accounts for mission application teams, preventing multi-tenant data comingling.
• Offline Pipeline Architecture: Build and maintain offline, air-gapped CI/CD pipelines tailored to execute in code-isolated environments without public internet connectivity or external SaaS dependencies.
  

Governance, Security, & Guardrails:

• Access Control Enforcement: Author and enforce strict Service Control Policies (SCPs) and IAM permission boundaries to prevent unauthorized lateral movement between multi-tenant program partitions.
• Centralized Security Logging: Configure centralized audit logging by routing AWS CloudTrail events directly to a secure, immutable, centralized S3 logging bucket for seamless ingestion into our on‑premises Splunk environment, including designing compliant alternatives when native services (e.g., GuardDuty or SQS‑based pipelines) are unavailable or not accredited in the air‑gapped region.
• Manual AMI Hardening: Lead the manual STIG hardening and security configuration of Red Hat Enterprise Linux (RHEL) and Windows Amazon Machine Images (AMIs) using localized Ansible and PowerShell scripts, managing the interim pipeline while AWS Image Builder remains unapproved on the high side.
• ATO Compliance Mapping: Map all cloud infrastructure configurations directly to DISA STIGs and NIST SP 800-53 controls to achieve first time pass rates during DCSA continuous monitoring audits.
  

Network & Hybrid Data Flow:

• Secure Hybrid Connectivity & Patch Ingestion: Design and maintain zero‑trust network connectivity between Secret‑level AWS environments and Secret‑level on‑prem systems using AWS Transit Gateway, Direct Connect, and software‑defined firewalls. Work with security and cross‑domain solution teams to define compliant, controlled processes for importing patches and updates from lower‑classification environments into the air‑gapped Secret environment.
• On-Premise DNS Reach Back: Design and manage conditional DNS forwarding architectures using Route 53 Resolver Endpoints pointing directly back to our on-premises Active Directory and DNS servers, explicitly avoiding the deployment of active domain controllers inside the cloud boundary.

Note: Due to the classified nature of the work being performed, this position does not offer any virtual or telecommute working options. Applicants are encouraged to apply, only if they are willing to work on-site.
