Database and Application Support Engineer (Senior)

About this role

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.

• Provide technical diagnosis, mitigation options, workarounds, recovery actions, restoration support, and service validation.

• Maintain detailed incident timelines covering symptoms, technical findings, actions, decisions, dependencies, communications, and restoration results.

• Escalate complex issues to database administrators, application owners, senior engineers, vendors, cloud providers, or development teams.

• Coordinate with Task 4 enterprise operations teams on infrastructure, server, network, cloud, storage, certificate, identity, and platform issues.

• Coordinate with Task 7 software-development teams when incidents require application-code review, defect correction, build changes, or software releases.

• Provide logs, traces, error details, reproduction steps, configuration information, and impact assessments to development teams.

• Validate that application-code corrections resolve the operational issue without introducing new availability or integration problems.

• Support development of temporary workarounds or contingency measures when complete restoration cannot be achieved immediately.

• Support root-cause analysis and document technical causes, contributing factors, dependencies, corrective actions, and preventive recommendations.

• Track post-incident corrective and preventive actions through completion.

• Support database, application, middleware, server, and appliance component upgrades and refreshes.

• Develop or execute implementation plans, upgrade procedures, test steps, validation criteria, rollback procedures, and outage contingencies.

• Coordinate approved maintenance, patching, configuration changes, migrations, and component replacements.

• Perform pre-implementation and post-implementation validation of database and application availability, connectivity, functionality, and performance.

• Support backup, restoration, replication, failover, failback, high availability, and disaster-recovery capabilities.

• Validate database and application recovery following outages, maintenance, migrations, restorations, or continuity events.

• Test service dependencies and end-to-end transaction paths after recovery.

• Support capacity, performance, availability, and resource-utilization analysis.

• Identify recurring failures, dependency risks, obsolete components, certificate risks, and potential points of failure.

• Apply or coordinate approved operating-system, database, middleware, application, vendor, firmware, and security updates.

• Support remediation of vulnerabilities, IAVAs, CND Directives, POA&M items, and security-control deficiencies.

• Follow approved incident, problem, change, configuration, release, availability, and service-continuity processes.
