Job Description

The Full-Stack Developer will serve as a cross-functional application developer and technical support resource across the NIMS/CMIS environment. This position is designed for a versatile developer who can work across application code, databases, APIs, cloud environments, testing, deployment, troubleshooting, and production support. The developer will work closely with the Senior ColdFusion/AWS Developer and Senior Oracle/SQL/Data Integration Developer, providing both development capacity and technical redundancy.

The position will assist with application enhancements, defect resolution, SQL/database development, system integrations, testing, deployments, documentation, helpdesk escalation, and future NISC V development. This position is particularly important to the team's continuity model: the developer will gain working knowledge across multiple NIMS/CMIS technical domains so that the team maintains secondary coverage for critical application and database functions.

Key Responsibilities

  • Develop, test, troubleshoot, and maintain enterprise web applications.
  • Support ColdFusion application development and maintenance.
  • Develop and troubleshoot SQL queries and database-driven functionality.
  • Support Oracle database and data-integration activities.
  • Develop and maintain APIs and system interfaces.
  • Assist with AWS-hosted application environments.
  • Troubleshoot application, database, integration, and production issues.
  • Perform bug fixes and implement application enhancements.
  • Conduct unit, integration, regression, and system testing.
  • Assist with user-acceptance testing and defect resolution.
  • Support source control, builds, deployments, releases, and CI/CD activities.
  • Support DevSecOps and vulnerability-remediation activities.
  • Provide Tier 1/Tier 2 technical support and resolve escalated helpdesk issues.
  • Support user account and application-access issues.
  • Assist with financial-data validation and troubleshooting.
  • Develop technical documentation, operating procedures, test documentation, and knowledge articles.
  • Participate in code reviews and peer testing.
  • Cross-train on both application and database functions to provide backup coverage.
  • Participate in Transition-In knowledge transfer and operational-readiness activities.
  • Support future NISC V design, development, testing, integration, and deployment activities. 
The FAA specifically requires first- and second-level helpdesk support covering user activation/deactivation, production issues and financial-data validation, in addition to application O&M responsibilities. Requirements Required Qualifications
  • Bachelor's degree in Computer Science, Software Engineering, Information Technology, or related discipline, or equivalent relevant professional experience.
  • 3+ years of professional software-development experience.
  • Experience developing enterprise web applications.
  • Experience with server-side/backend application development.
  • Working knowledge of ColdFusion or demonstrated experience with comparable application-development technologies and ability to learn ColdFusion.
  • Strong SQL skills.
  • Experience with Oracle or another enterprise relational database.
  • Experience developing or consuming APIs.
  • Experience with AWS or comparable cloud environments.
  • Experience with Git or comparable source-control systems.
  • Understanding of CI/CD and modern deployment practices.
  • Experience with software testing and defect resolution.
  • Experience troubleshooting production applications.
  • Ability to work across multiple technologies rather than within a single narrow technical specialty.
  • Strong analytical, troubleshooting, documentation, and communication skills.

Preferred Qualifications

  • Adobe ColdFusion experience.
  • Oracle 19c experience.
  • AWS experience or certification.
  • Federal Government application-development experience.
  • Experience with financial or contract-management systems.
  • Experience supporting DevSecOps, cybersecurity remediation, or ATO activities.
  • Experience supporting production helpdesk/service-desk escalations.
