At BAE Systems, we promote a strong, collaborative culture and provide our employees with the tools, skills and training they need to succeed. We are all about trust, camaraderie and a shared ambition to lead the world in defense technologies and national security services. We offer flexible work environment to support the balance in your life and keep you performing at your best. Be a part of a company that is part of the community; driven to improve our future and protect our freedom. We are seeking a Senior AWS Cloud Administrator to own and operate the classified and unclassified GovCloud AWS environments supporting the Advanced Technology team's SaaS application development, as well as help to protect and defend our NSS classified SIPRNET environment. As part of this role, you will also coordinate with our on-site cybersecurity team and lead vendor and software license coordination on behalf of Advanced Technology. You will build and maintain hands-on familiarity with our cybersecurity operations — including cyber threat analysis, incident response, and vulnerability assessment across Windows Server 2022 domain infrastructure, Windows 11 Enterprise workstations, Cisco networking infrastructure, Palo Alto firewalls, and enterprise security tools within our classified network environment. This position offers ownership of a growing AWS cloud environment supporting active SaaS development, plus regular working contact with our cybersecurity team. It's built for someone who wants a real cloud administration role grounded in hands-on classified-network cybersecurity experience, not just adjacent to it — with breadth, autonomy, and visibility across both teams. Primary Responsibilities Include: • Serve as cloud administrator for the Advanced Technology team's AWS environment supporting active SaaS application development • Manage AWS accounts, IAM, networking (VPC), storage, and compute resources in a classified/GovCloud context, in coordination with security and compliance requirements • Work directly with software and services vendors, and with internal program management operations, to track license statuses, renewals, and costs, and to plan and execute new software installs and updates • Coordinate with the on-site cybersecurity team on requirements, current activities, and upcoming changes relevant to Advanced Technology's systems and development plans • Proactively surface upcoming cybersecurity policy, tooling, or compliance changes to the Advanced Technology team so development plans can adapt ahead of time • Maintain hands-on fluency in the cybersecurity team's environment and tooling — monitoring, detecting, analyzing, and responding to cyber threats — to communicate effectively on technical requirements and constraints
