If you thrive in a dynamic, collaborative environment and love ensuring the delivery of high-quality software that directly impacts users, we want you to join us.
At Fastwork, we embrace the T-shaped engineer model—experts in specific areas but flexible enough to tackle challenges across the software development lifecycle.

Role Overview
As a QA Engineer, you’ll collaborate with talented teammates across engineering, product, and UX/UI teams in a supportive and open working environment. You’ll be responsible for designing, executing, and automating test strategies across backend, frontend, mobile, and infrastructure systems, ensuring our software is reliable, scalable, and user-centric.
We’re looking for individuals with a scientist mindset—curious, experimental, and unafraid to explore new ideas while learning from both success and failure.

  • Develop and maintain automated testing suites for web, mobile, and API testing using tools like Jest, Playwright, Patrol, and Swagger.
  • Validate user interfaces for usability and accessibility across frameworks like React (Next.js) and Svelte (SvelteKit).
  • Test backend services built with Node.js, Golang, Elixir, or Python for performance and reliability.
  • Contribute to the quality assurance of mobile apps developed using Flutter.
  • Collaborate with DevOps teams to ensure infrastructure stability through automated performance and load testing.
  • Review code and testing strategies, offering and receiving constructive feedback.
  • Advocate for and implement high-quality testing practices, including unit, integration, and end-to-end tests.
  • Monitor and report on key product quality metrics, identifying trends and areas for improvement.
Basic Qualifications

  • Proficiency in scripting or programming languages for test automation (e.g., JavaScript, Dart).
  • Familiarity with CI/CD pipelines and source control tools like GitHub.
  • Knowledge of Docker, Kubernetes, and cloud platforms (GCP, AWS) for performance and integration testing.
  • Strong communication skills and a collaborative mindset to thrive in Agile environments.
  • A scientist mindset—curious, experimental, and open to learning from failure.
  • A focus on making the product successful by identifying and eliminating defects early in the development process.
  • Self-motivation, adaptability, and a team-oriented attitude.

Preferred Qualifications
We’re especially excited if you bring:
  • Proven expertise in automated testing frameworks for web, mobile, and API testing.
  • A strong passion for delivering high-quality software that meets user expectations.
  • A deep understanding of quality metrics and how they drive product success.
