Original job description

Do you have a passion for operating enterprise infrastructure that enables thousands of builders to accomplish their mission in secure, air-gapped environments? Would you like to be the engineer that keeps critical communication and authentication services running across Amazon Dedicated Cloud regions?

Region Services Corporate Infrastructure (RSCI) Collaborative Services is looking for an experienced Windows System Engineer II with deep knowledge of enterprise messaging, network authentication, virtualization, and certificate services. You will operate and improve services that builders depend on daily - Exchange, Skype for Business, Certificate Authority, Network Policy Service (802.1x/RADIUS), HyperV, Data Protection Manager (DPM), SFTP/Diode staging infrastructure, HyperV hardware lifecycle management, and lab environments across multiple isolated Remote Management and Administration (RM&A) regions.

This position requires that the candidate selected must currently possess and maintain an active TS/SCI security clearance with polygraph. The position further requires the candidate to opt into a commensurate clearance for each government agency for which they perform AWS work.

Key job responsibilities

Manage/Operate and maintain enterprise services: Exchange, Skype for Business, Certificate Authority, NPS (802.1x), HyperV, and Data Protection Manager (DPM)
Troubleshoot complex Windows systems issues enterprise-wide across Active Directory, Group Policy, certificate enrollment, and network authentication
Security compliance including hardening OS, managing patching (Windows Server Update Services (WSUS)/Endpoint Configuration Manager (ECM)), and maintaining vulnerability SLAs
Manage metrics, monitoring, alarming, and dashboards for service health visibility
Create and update system documentation, runbooks for engineering, operations, and support teams
Respond to and resolve high-severity operational events; perform root cause analysis
Build PowerShell automation to reduce manual operational burden
Train and mentor junior engineers on Windows systems and ADC operations
Provide on-call support

A day in the life Our mission is to deliver robust, highly available, and easy to use enterprise services to our internal customers in support of the Amazon Dedicated Cloud for U.S. Government customers. We are looking for a motivated engineer to deliver results for our customers.

This is a hands-on position where your daily role will maintain and enhance existing services including Exchange mailflow, 802.1x network authentication, certificate enrollment, HyperV cluster operations, and backup/recovery. You will respond to operational events, drive automation of repetitive tasks, and ensure security compliance across all managed environments. This role works closely with Network Engineers, Data Center Operations, Security, Builder Experience, and partner teams to deliver integrated solutions.

You will have a strong and diverse technical background that allows you to approach problems with confidence and ingenuity. You must be a "lifelong learner", embracing rapid innovations in technology and understanding how to leverage them to continue to improve our services. A successful ADC Engineer will drive operational improvements, find ways to automate existing services, and provide escalation and mentoring for junior team members.
