All Jobs • Sr Application Platform Engineer (MBSE Apps)

Overview

We are looking for a Sr Application Platform Engineer experienced in configuring, deploying, and maintaining TeamWork Cloud and Cameo (and associated tools like Cassandra DB) as Application 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. The 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 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 IT technical services and technical expertise in systems, technical infrastructure, tools, modeling, external interfaces, and other technical areas
• Configure, deploy and maintain applications such as TeamWork Cloud and Cameo (and associated tools like Cassandra DB) as Application as Code (AaC) using CI/CD pipeline 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
• Create and maintain comprehensive test plans
• 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
• Monitor system performance
• Test new features, services and fix bugs
• Configure and deploy applications as code in CI/CD pipeline using DevSecOps tools to include Jenkins, Terraform, Ansible, GitLab, IdAM, Active Directory, LDAP resources
• Prepare technical presentations for government and senior leadership
• Work effectively in a team environment
• Work across infrastructure that contains both Linux (60%) and Windows (40%)
• 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

Qualifications

• Active TS/SCI w/ CI Polygraph required
• 10+ years of relevant experience
• Bachelor’s or master’s degree in a STEM field is required
• At a minimum, meet DoDD 8140 requirements (Security+ CE Certification)
• Experience configuring, deploying and maintaining TeamWork Cloud and Cameo (and associated tools like Cassandra DB) as AaC using CI/CD pipeline in a cloud-based environment
• Expertise configuring, deploying, and maintaining applications as AaC through Continuous Integration/Continuous Deployment (CI/CD)
• Ability to demonstrate solid engineering rigor
• Expert troubleshooting and solutioning skills
• Experience working with relational and/or non-relational databases (e.g. Cassandra, MySQL, MongoDB)
• Excellent written and verbal communication skills; ability to clearly and succinctly describe complex issues
• Experience integrating applications with workflow, case or ticketing, or automation platforms such as ServiceNow or custom-built systems
• Knowledge of IDAM requirements and technologies including Active Directory, SAML, OpenLDAP, OAuth 2.0, and/or OIDC
• Demonstrated experience with building comprehensive test plans for unit and user system testing and validation
• Strong documentation skills
• Developing integration interfaces using Python, PowerShell, and Groovy
