We are seeking a Mid-Level Software Engineer / Application Developer to support the stability, maintenance, security, and continuous improvement of an AI-enabled software platform operating within a federal/DoD technology environment.

The primary responsibility of this role is to investigate and resolve application defects, system issues, and technical problems identified through autonomous testing, human validation, monitoring, or user feedback.

The engineer will also perform quarterly AI model tuning and optimization, analyzing system performance and AI behavior and implementing controlled improvements to prompts, configurations, model interactions, workflows, and related application components.

• Investigate, troubleshoot, and resolve application bugs and system issues.
• Address confirmed defects identified through autonomous testing and human Test Engineer validation.
• Perform root-cause analysis for recurring and complex technical issues.
• Develop, test, document, and deploy reliable application fixes.
• Analyze application logs, APIs, databases, integrations, and infrastructure when diagnosing issues.
• Collaborate with Test Engineers to reproduce defects and validate implemented fixes.
• Address production issues and provide technical support for application incidents.
• Support application maintenance, upgrades, dependency updates, and security-related remediation.
• Participate in code reviews and follow established secure coding and development practices.
• Maintain technical documentation for application fixes, system behavior, configurations, and integrations.
• Support controlled application releases and deployments.
• Follow applicable government configuration-management and change-control processes.

• Follow applicable access-control, cybersecurity, data-handling, and acceptable-use requirements.

• Conduct scheduled quarterly reviews and tuning of AI/model performance.
• Analyze AI behavior using autonomous testing results, human validation findings, production observations, and user feedback.
• Identify patterns of inaccurate, inconsistent, incomplete, or undesirable AI behavior.
• Adjust approved prompts, configurations, model parameters, workflows, guardrails, and integrations as appropriate.
• Establish baseline measurements before significant tuning activities.
• Validate proposed model/configuration changes in approved non-production environments before release.
• Collaborate with Test Engineers to independently validate AI behavior following tuning.
• Document significant model, prompt, configuration, and behavioral changes.
• Maintain appropriate traceability and version history for AI-related changes.
• Evaluate tuning results against defined quality and performance criteria.
• Monitor for regressions and unintended behavior following updates.
• Ensure model tuning activities comply with applicable government security, privacy, data-handling, and AI governance requirements.

• 3–5 years of professional software engineering or application development experience.
• Strong experience developing and maintaining production web applications.
• Demonstrated experience troubleshooting and resolving application defects.
