- Collaborate with development teams to resolve interface dependencies and ensure successful integration across application environments.

Integration Testing and Troubleshooting

- Develop and execute integration tests to validate API functionality, data accuracy, response handling, and system interoperability.

- Use API testing tools such as Postman or comparable tools to validate requests, responses, status codes, and error handling.

- Troubleshoot API connectivity issues, authentication failures, data discrepancies, performance issues, and integration errors.

- Implement appropriate logging, monitoring, retry mechanisms, and exception handling to improve integration reliability.

- Document defects, investigate root causes, and coordinate with technical teams to implement corrective actions.

- Support integration testing, user acceptance testing, and production deployment activities.

Security and Performance

- Implement API authentication and authorization mechanisms, such as OAuth 2.0, API keys, and token-based authentication, as appropriate to the integration.

- Follow established security practices for data transmission, credential management, access controls, and sensitive information handling.

- Apply appropriate input validation, error handling, and secure coding practices to protect integrated systems.

- Monitor integration performance and identify opportunities to improve response times, reliability, and scalability.

- Support compliance with organizational, customer, and applicable regulatory requirements for data privacy and security.

Documentation and Collaboration

- Develop and maintain technical documentation, including API specifications, integration workflows, data mappings, configuration details, and troubleshooting procedures.

- Collaborate with software developers, data engineers, QA personnel, architects, and business stakeholders to define integration requirements.

- Participate in technical design discussions, code reviews, integration planning, and deployment activities.

- Support the maintenance and enhancement of existing integrations as business and technical requirements change.

- Identify opportunities to automate integration processes and improve development, testing, and deployment practices.

- Perform other related duties as assigned.

Minimum Requirements

- Bachelor's degree in Computer Science, Software Engineering, Information Technology, or Associates degree plus two years' experience.

- At least 3 years of professional experience in systems integration, API development, application development, or a related technical field.

- At least 3 years of hands-on experience developing, implementing, or supporting RESTful API integrations.

- Strong understanding of REST principles, HTTP methods, status codes, request and response structures, and API design concepts.

- Experience working with JSON and other structured data formats, including XML where applicable.

- Proficiency in at least one programming or scripting language, such as Python, Java, JavaScript, or C#.

- Experience testing and troubleshooting APIs using Postman, Swagger/OpenAPI tools, or comparable technologies.

- Understanding of API authentication and authorization methods, including OAuth 2.0, API keys, or token-based authentication.

- Experience diagnosing integration failures, validating data exchanges, and resolving technical issues across connected systems.

- Strong analytical, communication, documentation, and problem-solving skills.

- Ability to manage assigned integration tasks independently while collaborating effectively with technical teams.

- Must live in the Continental US.

- Be either a US citizen or Permanent Resident due to the work we do.

- Depending on agency requirements, you may need to possess or obtain a Public Trust designation or security clearance. Regardless of the specific requirement, all positions require the successful completion of a background check, background investigation, and the standard onboarding process.
