Overview
DecisionPoint seeks a Senior Database and Application Support Engineer to support database availability, application operations, service restoration, component upgrades, and recovery validation for the USMEPCOM ENLIST program.
The Database and Application Support Engineer will diagnose database outages, application dependencies, connection failures, unavailable services, certificate problems, and API-related issues. This role will support troubleshooting and restoration across database, application, middleware, server, network, cloud, and security components.
The engineer will coordinate operational response with Task 4 enterprise IT teams and work with Task 7 software-development teams when resolution requires application-code analysis or correction. The role will focus on production support, infrastructure integration, recovery, and technical coordination rather than serving as the primary application developer.
This position is remote, with a preference for candidates located in the Chicago area. After- hours work may be required during outages, deployments, maintenance windows, upgrades, and recovery activities.
Note: By applying to this position, you acknowledge and consent to having your resume included in an active competitive government contract bid.
Duties & Responsibilities
The Database and Application Support Engineer will:
- Monitor and support the availability, performance, health, and recoverability of enterprise databases and applications.
- Diagnose database availability issues, failed services, connection failures, authentication problems, resource constraints, and performance degradation.
- Analyze application dependencies across databases, servers, services, middleware, APIs, certificates, networks, cloud platforms, storage, and external interfaces.
- Troubleshoot database listeners, connection strings, connection pools, ports, drivers, service accounts, permissions, and network paths.
- Investigate failed database connections, application timeouts, unavailable services, transaction errors, and data-access issues.
- Review database, application, middleware, operating-system, web-server, API, and network logs to isolate faults.
- Use monitoring data, metrics, traces, alerts, logs, and event records to identify the source and scope of service disruptions.
- Diagnose certificate expiration, trust-chain, hostname, binding, private-key, protocol, and encryption-related failures.
- Support installation, renewal, replacement, validation, and troubleshooting of certificates used by applications, databases, APIs, and supporting services.
- Diagnose REST, SOAP, API gateway, endpoint, authentication, authorization, payload, timeout, and connectivity failures.
- Validate dependencies among APIs, backend services, databases, certificates, identity providers, and network controls.
- Support administration and troubleshooting of relational database platforms used within the enterprise environment.
- Support application servers, web servers, middleware, schedulers, integration services, background services, and supporting runtime components.
- Participate in Outage Response Team activities involving database or application degradation and service outages.
