🚀 QA Engineer — Break Things Beautifully


Are you passionate about catching bugs before anyone else sees them? Do you enjoy breaking things so the team can build them better? We’re looking for a Mid to Senior QA Engineer to join our growing team who’s as obsessed with quality as we are.


At our B2B web platform, you’ll be the guardian of smooth, secure, and scalable software—working closely with devs, POs, and stakeholders to ensure our product is robust, scalable and secure. The backend is built with GoLang, the frontend in TypeScript, and we’re pushing forward with both manual and automated testing.


Why Join Us?

🔍 Quality with Impact – Own meaningful testing work that keeps the product stable, secure and delightful to use.

🛠 Shape the Process – Contribute directly to automation frameworks and influence how we test across the pipeline.

🤝 Fast, Focused, Supportive – Startup pace, B2B impact, team-first mindset.

🌎 Flexibility – Remote-friendly, async-friendly and built around trust.

💰 Compensation – We invest in top talent — and we mean it.

🏖 Extra Time Off – Burnout isn’t part of the job description.

🩺 Private Health Plan – We’ve got your back (and the rest of you too).

✈️ Travel Budget – Sometimes you’ve got to zoom out and explore the world.

📚 Continuous Learning – Conferences, tools, and courses — curiosity encouraged.

🎉 Epic Team Culture – We take our work seriously, not ourselves.


🛠 What You’ll Be Doing

  • Own and execute testing for new features and enhancements
  • Design and maintain manual and automated test cases for the frontend and backend
  • Collaborate with developers to define acceptance criteria and testing strategies
  • Perform API testing, integration testing, regression testing and UI validation
  • Identify, document and help triage bugs
  • Contribute to the automation framework and CI/CD pipelines
  • Advocate for best QA practices across the development lifecycle
  • Collaborate in an Agile/Scrum environment with short release cycles


🧠 What You Bring

  • 3+ years of experience in software QA, including web application testing
  • Strong knowledge of testing methodologies, tools, and processes
  • Experience testing REST APIs and microservices
  • Familiarity with GoLang-based systems — no need to write Go, just know how to test it
  • Comfortable working with frontend apps using TypeScript or JavaScript
  • Automation experience with tools like Cypress, Playwright or Selenium
  • A knack for writing clean bug reports and solid documentation
  • Confidence using tools like Postman, Swagger, Jira and TestRail


🔍 Bonus Points If You Have

  • Background in fintech or payments
  • Understanding of compliance and data security (e.g., PCI, GDPR)
  • Experience building or maintaining test automation frameworks


👉 Ready to join a team where quality matters as much as features? Send us your CV — and let’s ship things that don’t break.
