Join a team that powers the business enterprise behind the mission, supporting the sustainment, modernization, and transformation of more than 100 enterprise business systems that enable tens of thousands of government personnel, industry partners, and prospective employees worldwide. These mission-enabling applications support workforce management, finance, acquisitions, security processing, training, recruitment, logistics, program management, executive decision-making, and other critical business functions across multiple secure environments.

We are seeking a Senior Systems Integrator supporting the Government's Corporate Management Services (CMS) organization.

• Perform minor system administration activities, including environment management, user administration, configuration management, and operational support.
• Work with relational databases to troubleshoot issues, execute queries, validate data, and support application functionality.
• Analyze system logs, monitor application health, identify root causes of issues, and coordinate resolution across technical teams.
• Develop scripts and implement minor code enhancements to improve automation, system functionality, and operational efficiency.
• Collaborate with Government Product Leads, developers, system administrators, database administrators, and other stakeholders to implement technical solutions and support system enhancements.
• Develop and maintain technical documentation, including system architecture, integration diagrams, configuration guides, operational procedures, and support documentation.
• Participate in Agile ceremonies and contribute to sprint planning, backlog refinement, testing, and release activities.
• Identify opportunities to improve system performance, reliability, maintainability, and operational processes.
• Support incident response activities and help resolve production issues while minimizing system downtime.
• Mentor junior engineers and provide technical guidance on application integrations, configurations, and operational best practices.

Qualifications:

• Active TS/SCI with Full Scope Polygraph
• A bachelor's degree and twelve (12) years of experience in software development/engineering. Sixteen (16) years of software development experience may be substituted in lieu of a degree.
• Willingness to embrace challenges and seek to become an expert in the products.
• Experience with COTS integration.
• Experience developing and updating technical documentation.
• Skilled in problem solving and troubleshooting computer systems and software.
• Experience with Bash, PowerShell, or Python.
• Experience with agile development methodologies.
• Experience closely collaborating with the Government customer.
• Knowledge of SQL Server Database.

Desired Skills:

• Experience managing systems hosted in virtual environments such as AWS
• Experience with the Atlassian Tool Suite including Confluence & Jira
• Experience with Nessus and Tenable Security Center
• Experience with .NET
• Experience with programming languages Java, PHP, and C#
