  • Participate in architectural discussions, tool evaluations, and roadmap planning
  • Mentor junior engineers and contribute to engineering best practices
Required Skills & Experience
  • SDET – Back-end focus
  • ETL testing
  • Strong SQL (expert-level): writing queries/stored procedures on demand, validating large datasets, and troubleshooting end?to?end data flows
  • Java automation: triaging/fixing Java code on the fly and building/extending automation frameworks
  • API testing & integration testing
  • CI/CD, DevOps, and code quality practices
  • Experience in cloud environments (AWS preferred)
  • Experience in large enterprise-class systems
  • System design, development, and debugging

  • Expertise with CI/CD tools and pipelines
  • Knowledge of TDD, BDD, and automated acceptance testing
  • Strong understanding of code quality and promotion practices
Qualifications & Preferred Skills
Qualifications
  • Bachelor’s degree in Computer Science, IT, or related field (or 4 additional years of relevant experience)
