  • Write and maintain unit and integration tests; participate in the design of CI/CD workflows
  • Analyze code and communicate detailed, actionable reviews to development teams
  • Apply cloud-native patterns to ongoing platform innovation
  • Develop applications that run in serverless (AWS Lambda) or managed Kubernetes environments (AWS EKS, Fargate)
  • Participate in occasional client-facing meetings
  • Lead projects, feature requests from requirements through delivery
  • Mentor junior developers through code reviews, pair programming, and technical guidance
  • Support deployment and maintenance activities, off-hours, as needed
  • Occasional travel for internal meetings (<10%)

QUALIFICATIONS:

  • 5+ years of development experience working within a modern full-stack web application environment
  • Bachelor's degree in computer science or information technology, or commensurate experience
  • Strong experience with Angular
  • Experience with Spring or Spring Boot
  • Experience with relational databases (MySQL preferred), including schema design, query optimization, and data modeling
  • 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:
Compensation for this role varies depending on several factors including work location, level of experience, and skill set. As required by applicable law, the hiring range for this position is $115,000 - $125,000.
