This role supports enterprise-scale backend and frontend systems with a focus on resiliency, scalability, and security.

Required Qualifications:

  • Experience with front-end frameworks such as React for creating responsive user interfaces.
  • Strong understanding of CI/CD practices and Agile development within a SAFe framework.
  • Familiarity with Atlassian tools (Bitbucket, Jira) for version control and workflow management.

Responsibilities:

  • Design, develop, and maintain mission-critical enterprise applications across the full SDLC.
  • Architect and deploy cloud-native solutions leveraging AWS infrastructure (EC2, Lambda, RDS, DynamoDB).
  • Develop intuitive and user-friendly front-end interfaces using React and modern web technologies.
  • Manage version control and CI/CD workflows using Bitbucket, Jira, and automated testing tools.
  • Translate stakeholder and business requirements into robust technical solutions.
  • Conduct comprehensive unit and integration testing to ensure application quality and security compliance.
  • Support continuous improvement by implementing system patches, updates, and performance enhancements.
  • Collaborate with cross-functional teams to conduct architecture reviews and align technical solutions with strategic goals.
  • Provide technical documentation and contribute to knowledge-sharing within the team.
  • Participate in Agile ceremonies and prioritize backlog items in alignment with business needs.
  • Offer training and mentorship to other team members as needed.
