  • Familiarity with search technologies such as OpenSearch/Elasticsearch
  • Proficiency with Git-based workflows
  • Familiarity with automated testing practices and CI/CD pipelines
  • Ability to review and interpret client requests with product owners and analysts
  • Comfortable working independently with limited supervision
  • Strong organizational skills with the ability to manage multiple priorities
  • Familiarity with other front-end frameworks like React, Vue, or similar
  • AWS certifications (Developer Associate, Solutions Architect, or equivalent)
  • Candidates must be legally authorized to work in the U.S. without sponsorship now and in the future

SALARY & BENEFITS:
