Systems Administrator

$78.4k - $129.4k

ASM Research, An Accenture Federal Services Company

The Database/Middleware Engineer, Mid provisions, configures, and administers enterprise middleware platforms that connect distributed applications and databases in a highly regulated government environment. The role owns day-to-day middleware operations, including monitoring, incident troubleshooting, and performance tuning to maintain stable, secure integrations for mission-critical systems. This engineer leads patching, upgrades, migrations, and decommissioning activities for middleware software while aligning all changes with enterprise security, change management, and lifecycle standards.

Key Responsibilities

  • Deploy, configure, and maintain middleware platforms such as enterprise application servers, web servers, and messaging systems, tailoring settings for reliability, scalability, and observability across environments.

  • Monitor middleware performance and availability using logs, metrics, and alerting tools, diagnose complex integration issues, and implement tuning changes to improve throughput and stability.

  • Plan and execute middleware patching, upgrades, and environment migrations, including coordination of maintenance windows, rollback strategies, and post-change validation for mission-critical services.

  • Design and enforce middleware security configurations, including authentication and authorization models, TLS certificates, cipher suites, and secure configuration baselines that align with enterprise and regulatory requirements.

  • Implement and maintain backup and recovery approaches for middleware configurations, scripts, and artifacts, and participate in continuity of operations and disaster recovery exercises.

  • Document and maintain detailed runbooks, architecture and connectivity diagrams, inventories, and lifecycle roadmaps for middleware components to support audit, compliance, and knowledge transfer.

  • Evaluate new middleware products and features, perform proof-of-concept implementations, and provide recommendations on standards, patterns, and best practices for enterprise adoption.

  • Coordinate with application teams to support deployments, troubleshoot application-to-middleware issues, and optimize connection pooling, thread usage, and resource configuration.

Required Qualifications

  • Bachelor’s degree (BA/BS) in Computer Science, Information Technology, or a related field, or equivalent relevant work experience.

  • 4–7 years of hands-on middleware engineering or administration experience supporting production or mission-critical environments.

  • Strong proficiency with middleware technologies and tools, including monitoring, troubleshooting, patching, migrating, and upgrading middleware environments in multi-tier architectures.

  • Demonstrated understanding of security standards, best practices, and lifecycle management for middleware applications, including configuration of secure protocols and access controls.

  • Experience documenting and maintaining comprehensive operational procedures, connectivity diagrams, and lifecycle support plans for middleware platforms.

  • Active SECRET security clearance or ability to obtain and maintain clearance as required by the client.

  • U.S. citizenship and willingness to travel less than 10% of the time.

Preferred Qualifications

  • Experience administering enterprise middleware stacks such as WebLogic, WebSphere, JBoss, Tomcat, or similar platforms in complex, multi-tier architectures.

  • Familiarity with message-oriented middleware, integration platforms, or API gateways supporting event-driven and service-based architectures.

  • Professional certifications or advanced training focused on middleware administration, integration platforms, or related infrastructure technologies.

  • Prior experience operating in highly regulated or federal IT environments with mature change management, security, and compliance frameworks.
