  • Implement API endpoints and UI components following the team's established patterns and conventions.
  • Write clean, tested code, and actively participate in code review, both receiving and giving feedback, as a core part of how you learn the codebase and standards.
  • Contribute to and help maintain the shared component library under guidance, keeping the user experience consistent across applications.
  • Assist with everyday platform operations, deployments, monitoring, and basic troubleshooting, alongside more experienced team members.
  • Document your work clearly and raise questions early; asking for help is an expected and valued part of this role.
  • Work with product and operations stakeholders (with support from your team) to understand requirements and turn them into working software.
