The Role

We focus on building 7 to 10 high-potential startups at a time. On each of our startups, we have a small and effective team ranging from 5 to 15 people. An essential member of each team is a QA Engineer who is the gatekeeper of quality on the project and the glue between the engineering team and the product requirements.

You’ll be responsible for implementing and maintaining the test strategy, and test plans, and manually testing the product to ensure seamless e2e experiences. Beyond testing stories, you will be responsible for the overall quality of the product and will ensure that the application functions flawlessly from the users' perspective. Collaborating closely with our Tech Lead, you'll streamline workflows and help organize releases. You'll be the ultimate decision-maker, giving the green light for each release. You’ll collaborate with Engineers to clarify product functionalities and provide them with testing data. Most importantly you’ll be a partner to the Product Manager, gaining insights into the business and project scope to determine quality assurance priorities and to set effective testing strategies.

If you're highly proactive, well-organized, and passionate about quality products, this position is perfect for you!

  • Drive the whole QA process and testing lifecycle
  • Measure and report key quality metrics to the team and stakeholders
