• Support off-hours deployments as needed (evenings/weekends) to meet mission timelines and operational requirements.
• Participate in team demos and stakeholder presentations to showcase platform capabilities and progress.

What You Need To Have

  • Git-based version control (GitHub/GitLab)
  • PostgreSQL and/or MongoDB
  • Agile development methodology (Scrum/Kanban)
  • Collaboration tools such as Jira and Confluence
• Ability to work effectively in a collaborative, delivery-oriented product team and produce high-quality, maintainable code

What We’d Like You To Have
