Job description

Overview: We are looking for a Senior Infrastructure Systems Engineer experienced in configuring, deploying, and maintaining infrastructure tools and COTS applications as Infrastructure as Code (IaC) and Applications as Code (AaC) to join our visible technical program driving the Model Based Systems Engineering (MBSE) cloud platform that supports collection, management and analysis of digital engineering information in an architecture that provides seamless digital thread and enables tool interoperability, including data structures suitable for AI applications. This program delivers engineering services for Linux and Windows cloud-based infrastructure as well as sophisticated enterprise computing infrastructure including end-point devices, Cloud services, virtualized applications, and storage systems. Enterprise Computing Engineering services include modern application technology including containerized solutions with orchestrated workflows. Our platform uses a mix of Open Source, Government-off-the-Shelf (GOTS) and Commercial off-the-Shelf (COTS) software and targets cloud-native constructs. The environment offers a secure-by-default configuration, implementing an Infrastructure-as-Code approach, and governance policies. We follow a mostly Agile workflow and adhere to DevSecOps principles. We value fast iteration and a customer-oriented approach while being mindful about security. This is a fast paced, challenging, and career rewarding experience to recruit and develop top talent and solutions on one of the most complex and high-profile programs within the government customer community.
Responsibilities:

• Provide platform and infrastructure technical services and technical expertise in systems, technical infrastructure, tools, modeling, external interfaces, and other technical areas
• Complete complex design, configuration and deployment of platform infrastructure and applications in a cloud-based environment ensuring performant environments
• Maintain COTS applications in a cloud-based environment
• Work with internal engineering resources as well as customer end-users to design and enhance the user interfaces for supported applications, maintaining responsive designs that accommodate challenging technical and functional requirements
• Support operations functions, including root cause identification, remediation and documentation (e.g., user guides, 'how to' guides, infrastructure diagrams)
• Work closely with clients and cross-functional departments on technical issues including software system troubleshooting and maintenance and to communicate project statuses
• Prepare comprehensive test plans, test new features, services, and fix bugs
• Configure IdAM, Active Directory, LDAP resources with platform and applications
• Prepare technical presentations for government and senior leadership
• Work effectively in a team environment
• Work across infrastructure that contains both Linux and Windows
• Communicate effectively with technical and non-technical, management and customer both written and verbally
• Instill and apply solid engineering rigor, to include configuration management, testing
• Develop/engineer as part of an Agile scrum team
