About the position

We are looking for QA engineers who are passionate about quality to join KOMOJU’s growing QA team. The QA team is dedicated to measuring, understanding, and communicating the overall quality of our products. This involves reviewing design specifications, executing tests, reporting technical issues, building innovative automated testing solutions, and closely collaborating with engineering teams, product managers, and other stakeholders. You will be one of the first few members of our QA team, closely collaborating with our Team Lead to help shape quality across KOMOJU. This isn’t just a manual or automation test role - we are looking for individuals, from junior to senior engineers, who want to positively impact all aspects of quality.

Responsibilities

  • Identify opportunities for quality improvement, and advocate for process change in order to strengthen the quality of our products
  • Work closely with engineering teams, product managers, and other stakeholders to understand technical requirements and provide input on design considerations
  • Develop test plans appropriate for the scope and scale of our projects
  • Execute manual and exploratory tests
  • Identify, document, and prioritize defects and issues
  • Build new and innovative test automation solutions
  • Contribute toward building a culture of quality by helping to define quality processes in a team with maturing QA practices
  • Proactively collaborate with engineering and business teams

Requirements

  • You are proficient in at least one programming language (e.g. JavaScript, TypeScript, Ruby - though not limited to these) - a bonus if you have experience that goes beyond writing automated tests
  • In-depth hands on experience with automated testing tools like Playwright, Capybara, and RSpec (though not limited to these)
  • You love to empower other engineers and strive to understand how to help them deliver quality features and products for our customers
  • Collaborative mindset and eagerness to learn and grow
  • Comfortable building processes where they may not yet exist
  • You have excellent debugging skills
  • You can run with ambiguous requirements and have a strong bias to action
  • You have a tester mindset, are curious, and come up with interesting test scenarios
  • Experience with cloud platforms (e.g. AWS)
  • Experience with designing release/regression/smoke-testing strategies
  • Experience with manual and exploratory testing
  • Experience creating and executing test plans

Nice to haves

While not specifically required, tell us if you have any of the following.

  • Experience with performance testing
  • Experience with testing mobile applications
  • Experience with multilingual applications
  • Experience using observability tools (e.g. Datadog)
