- Collaborate with Government Product Leads, developers, system administrators, database administrators, and other stakeholders to implement technical solutions and support system enhancements.
- Develop and maintain technical documentation, including system architecture, integration diagrams, configuration guides, operational procedures, and support documentation.
- Participate in Agile ceremonies and contribute to sprint planning, backlog refinement, testing, and release activities.

- Support incident response activities and help resolve production issues while minimizing system downtime.
- Mentor junior engineers and provide technical guidance on application integrations, configurations, and operational best practices.
