A photo and media hosting platform is looking for a strong Software Development Engineer in Test to help evolve and scale quality engineering practices across both web and mobile platforms.

The team is moving toward a more automation-driven and AI-assisted quality engineering model while still requiring hands-on manual QA support where needed. This role requires both strong engineering capabilities and practical QA experience.

The ideal candidate will be capable of designing, developing, and maintaining scalable automated test solutions while also supporting exploratory and regression testing activities for complex web and React Native applications.

This role will work closely with developers and product stakeholders to improve product quality, automation coverage, release confidence, and AI-assisted testing workflows.

  • Develop and expand Maestro-based mobile automation coverage 
  • Create and maintain web automation suites using modern automation tools 
  • Support AI-assisted test authoring workflows, including prompt and agent skill maintenance 
  • Review, validate, and debug AI-generated test output 
  • Perform exploratory, regression, and release testing when necessary 
  • Work with developers to improve application testability and automation coverage 
  • Integrate automated tests into CI/CD pipelines 
  • Investigate, troubleshoot, and debug issues across application and automation layers 
  • Contribute to quality engineering standards, best practices, and process improvements 
  • Collaborate closely with software engineers, product managers, and QA stakeholders
