Overview

DecisionPoint seeks a Journeyman 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 troubleshoot incidents across database, application, middleware, server, network, cloud, and security components.

The engineer will coordinate response activities with Task 4 enterprise IT operations personnel and work with Task 7 software teams when resolution requires application-code analysis or correction. This position focuses on production support, infrastructure integration, recovery, testing, and operational 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.

Review operational alerts, service failures, database errors, application errors, performance degradation, and user-reported issues.

Diagnose database availability issues, failed services, connection failures, authentication problems, resource constraints, and performance issues.

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 problems.

Review database, application, middleware, operating-system, web-server, API, and network logs to isolate faults.

Use monitoring data, alerts, logs, metrics, and traces to identify the source and scope of service disruptions.

Diagnose certificate expiration, trust-chain, hostname, binding, private-key, protocol, and encryption-related failures.

Support certificate installation, renewal, replacement, validation, and troubleshooting for applications, databases, APIs, and supporting services.

Diagnose REST, SOAP, API gateway, endpoint, authentication, authorization, payload, timeout, and connectivity issues.

Validate dependencies among APIs, backend services, databases, certificates, identity providers, and network controls.

Support approved relational database platforms and associated management, monitoring, backup, and recovery tools.

Support application servers, web servers, middleware, schedulers, integration services, background services, and runtime components.

Participate in Outage Response Team activities involving database or application degradation and service outages.

Perform technical triage, gather diagnostic information, and support implementation of approved mitigation and recovery actions.

Support development and validation of temporary workarounds when complete restoration cannot be achieved immediately.

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

Escalate complex database, application, API, certificate, infrastructure, or code-related issues to senior engineers and responsible technical teams.

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

Coordinate with Task 7 software 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 software teams.

Support testing and validation of application-code corrections in applicable nonproduction and production environments.
