  • Troubleshoot and debug API issues, identify root causes, and implement solutions to ensure high availability, fault tolerance, and disaster recovery.
  • Mentor junior developers, provide technical guidance, code reviews, and feedback to foster their professional growth and development.
  • Collaborate with stakeholders to gather feedback, analyze usage metrics, and iterate on API designs and features to meet business objectives and user needs.

  • Excellent problem-solving skills, analytical thinking, and attention to detail.
  • Effective communication skills, teamwork, and collaboration in an Agile/Scrum environment.
