Software Tester / QA Engineer (Web & API Testing)

We are seeking a detail-oriented and technically skilled Software Tester / QA Engineer to support testing of modern web-based applications and API-driven systems. This role is ideal for someone who enjoys digging into systems, validating functionality end-to-end, and building automated test coverage in a fast-paced environment.

Responsibilities

  • Test web-based applications for functionality, performance, and usability
  • Validate API endpoints exposed through API gateways and backend services
  • Design, execute, and maintain manual and automated test cases
  • Use tools such as Postman and Swagger to test, document, and validate APIs
  • Develop and maintain automated test scripts using frameworks such as Cypress or similar tools
  • Analyze test results, identify defects, and clearly document issues for engineering teams
  • Collaborate with developers, product owners, and other stakeholders to ensure quality across releases
  • Participate in sprint planning, backlog grooming, and Agile ceremonies
  • Perform regression, integration, and system-level testing across environments

Required Qualifications

  • 3+ years of experience in software testing or quality assurance
  • Strong experience testing web applications and RESTful APIs
  • Hands-on experience with API testing tools (e.g., Postman, Swagger)
  • Experience with test automation frameworks (e.g., Cypress or equivalent)
  • Understanding of programming/scripting languages (JavaScript preferred; Python, Java, or similar also acceptable)
  • Familiarity with HTTP protocols, JSON, and API authentication methods
  • Ability to read and interpret API specifications and documentation
  • Strong analytical skills and attention to detail
  • Experience working in Agile/Scrum environments

Preferred Qualifications

  • Experience testing systems that operate through API gateways or distributed architectures
  • Familiarity with CI/CD pipelines and integrating automated tests into build processes
  • Experience with version control systems (e.g., Git)
  • Knowledge of performance or load testing tools
  • Exposure to cloud environments (AWS, Azure, or similar)

What We’re Looking For

  • Someone who takes ownership of quality and doesn’t just “check the box”
  • A tester who can think like both a user and a developer
  • Strong communicator who can clearly explain issues and risks
  • Self-starter comfortable working in a small, high-performing team
