Senior Full-Stack Software Developer

About this role

Overview
DecisionPoint seeks four Senior Full-Stack Software Developers to design, implement, test, secure, and modernize mission-critical software capabilities for the USMEPCOM ENLIST program. These roles develop complex features across front-end and back-end application layers, build and integrate APIs, correct security findings, perform code reviews, and support reliable software releases.
The Senior Full-Stack Software Developers work with architects, mission liaisons, requirements analysts, UI/UX specialists, testers, cybersecurity personnel, DevSecOps engineers, and Government stakeholders. They also mentor other developers and cross-train across critical components to improve delivery continuity and reduce key-person dependencies.
These positions are remote, with Chicago-area candidates preferred.
Note: By applying to this position, you acknowledge and consent to having your resume included in an active competitive government contract bid.

• Implement approved security fixes and coordinate remediation with cybersecurity, testing, and platform teams.

• Apply secure coding practices throughout design, development, testing, integration, and deployment.

• Develop and maintain unit tests, integration tests, regression tests, and other automated quality checks.

• Participate in peer reviews, code reviews, design reviews, and architecture discussions.

• Review source code for correctness, security, performance, testability, maintainability, and compliance with established development standards.

• Diagnose and resolve complex defects, integration failures, performance issues, and production-support concerns.

• Support root-cause analysis and implement durable corrective actions.

• Use approved version-control practices, including branching, merging, pull requests, tagging, and release management.

• Support continuous integration and continuous delivery pipelines, automated builds, testing, and deployment activities.

• Develop and maintain technical documentation, API documentation, build instructions, installation procedures, and release artifacts.

• Support sprint planning, backlog refinement, daily coordination, demonstrations, reviews, retrospectives, and release-readiness activities.

• Provide accurate estimates and identify technical risks, dependencies, assumptions, and implementation constraints.

• Coordinate work with architecture, infrastructure, cloud, database, cybersecurity, testing, training, and operations teams.

• Mentor junior and journeyman developers through technical guidance, code reviews, pairing, and knowledge sharing.

• Cross-train on critical application components and provide coverage during absences, incidents, releases, and priority remediation activities.

• Support Government demonstrations, user acceptance testing, operational validation, and stakeholder feedback.

• Protect sensitive data and comply with applicable federal, DoD, security, privacy, and configuration-management requirements.

• Contribute to continuous improvement of software-engineering, testing, documentation, and delivery practices.
