Serbia Constructor TECH Full time

The Software Developer Engineer in Test (Playwright / TypeScript) at Constructor Tech will play a critical role in designing, implementing, and evolving our automation strategy and frameworks with a focus on Playwright and TypeScript. This role combines deep technical expertise with a passion for efficiency, reliability, and innovation in testing — including the adoption of AI-driven testing and Modular Composable Platforms (MCPs).

You will collaborate closely with development, DevOps, and QA teams to ensure automation excellence across all layers of the delivery process.

Key Responsibilities

  • Design, build, and maintain scalable automation frameworks using Playwright and TypeScript for web and API testing.
  • Define and evolve test automation strategy, processes, and best practices to ensure consistent quality across projects.
  • Develop and maintain robust, reusable test suites and utilities for regression, smoke, and integration testing.
  • Integrate automation into CI/CD pipelines (e.g., Jenkins, GitLab CI) to enable continuous testing and fast feedback loops.
  • Collaborate with developers and DevOps engineers to ensure test environments and data are stable and reliable.
  • Apply white-box and gray-box testing techniques to ensure thorough coverage of both frontend and backend components.
  • Contribute to the adoption of AI-assisted testing tools and automation intelligence for test creation, maintenance, and analytics.
  • Participate in exploration and implementation of MCP-based automation components and reusable service connectors.
  • Provide technical guidance through mentoring and peer reviews, helping less experienced QAs enhance their automation expertise and code quality.
  • Continuously improve test performance, reliability, and reporting visibility through innovation and tool evaluation.

Requirements

  • Bachelor's degree in Computer Science, Information Technology, or equivalent experience.
  • 4 years of experience in QA and automation, including 2 years with Playwright and TypeScript.
  • Proven experience in building test automation frameworks from scratch.
  • Solid understanding of SDLC, QA methodologies, and automation design principles.
  • Strong knowledge of TypeScript and/or Python for test development.
  • Experience with REST API testing, SQL, and relational databases.
  • Familiarity with Jenkins, GitLab CI, and Git for continuous integration and source control.
  • Strong analytical and troubleshooting skills with a proactive, ownership-driven mindset.
  • Fluent in English, both written and verbal.

Nice to Have

  • Experience with AI-powered testing tools or model-based testing.
  • Familiarity with Linux, Docker, and Kubernetes (K8s).
  • Knowledge of mobile automation frameworks such as Appium or similar tools.
  • Understanding of MCP architecture and how it can enhance modular automation.
  • Knowledge of performance or security testing concepts.
  • Experience working in Agile or Kanban environments.
