About the Opportunity:
ZipStaff is seeking a Senior SDET for a workflow-driven microservices platform supporting enterprise workforce management at a major passenger-rail and transportation organization.

  • Build resiliency tests: retries, failure handling, idempotency.
  • Embed automation in Jenkins, GitHub, or Bitbucket pipelines.
  • Use CloudWatch, Dynatrace, AppDynamics, or ELK under load.
  • Set quality gates with developers, POs, and architects.
  • Mentor engineers; cover modern plus mainframe/batch integrations.

Required Qualifications:
  • Bachelor’s or 7+ years equivalent.
  • 5+ years manual and automated testing of complex enterprise systems.
  • Java and TypeScript for automation.
  • Strong UI, API, and microservices testing.
  • Strong SQL (relational and NoSQL validation).
  • Agile / DevOps delivery.
  • Able to travel for quarterly PI planning (client covers travel, lodging, and select meals).
  • Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:
  • Transportation, logistics, rail, or financial platforms.
  • Kafka / event-driven testing.
  • JMeter; AWS.
  • Mainframe / 3270 / batch-to-modern integration testing.

To apply, submit your resume highlighting Java/TypeScript automation, API + UI frameworks, Kafka or messaging tests, and CI/CD quality gates.
