【About The Role】 As an SDET (Software Development Engineer in Test) at PicCollage, you’ll play a key role in shaping how we build, test, and deliver high-quality creative products used by hundreds of millions of people worldwide. You’ll help drive the reliability, scalability, and speed of our entire engineering process—through automation, infrastructure, and quality practices.

You’ll work across multiple platforms and languages—spanning iOS, Android, Backend, and CI/CD systems—to design smarter workflows and deliver seamless collaboration between development, testing, and release. Beyond traditional automation, you’ll also explore new frontiers where AI and engineering meet—applying machine learning to improve test coverage, enhance developer efficiency, and ensure the quality of our AI-powered user experiences.

【What You’ll Do】

  • Develop and optimize multi-platform test automation frameworks for iOS, Android, Backend, and potential Web Frontend, ensuring reliable, scalable, and maintainable systems.
  • Build and maintain hybrid (cloud + self-hosted) distributed job systems to orchestrate large-scale build, test, deployment, and CI/CD workflows.
  • Develop cloud services that support and extend our automation, testing, and infrastructure capabilities.
  • Design and implement SDKs and shared packages to streamline automation and testing across teams.
  • Leverage AI to enhance testing, development, verification, and other areas that improve engineering productivity and coverage.
  • Collaborate with Developers, PMs, and Testers to solve product needs through automation and tooling, driving continuous improvement and a culture of quality and innovation.

【What We’re Looking For】

  • Experienced in Kotlin and Swift, with the ability to build and debug apps, tools, or automation.
  • Passionate about continuously improving and dedicated to designing, implementing, and maintaining automated test frameworks, CI/CD pipelines, and internal developer tools.
  • Enjoy solving complex quality and infrastructure challenges through automation and scalable system design.
  • Collaborative and communicative, working effectively with developers, PMs, and other stakeholders.
  • Have practical experience using AI in engineering or problem-solving, and enjoy continuously learning and experimenting with new technologies.
  • Passionate about delivering high-quality products that users love and trust.

【Nice-To-Haves】

  • Hands-on experience with iOS or Android UI test automation in CI/CD environments.
  • Built and maintained Ruby programs, gems, or cloud services.
  • Experience optimizing self-hosted CI infrastructure.
  • Hands-on experience applying AI in test automation, for example, in validation, image comparison, or generating test data and cases.

【Interview process 面試流程】 There are three main stages in our interview process:

  • Screen calls (1-2 calls)
  • Take-home quiz & review
  • Onsite interview (3-4 hours visiting)

If we see a fit with the company, we will reach out to start getting to know each other. You can expect traditional discussions as well as participating situational exercises. The goal of the interview process will be for us to see your skills and let you get to know the team and work culture to see if we are a match.
