About the Role

We are seeking a Senior QA Automation Engineer with a strong background in backend testing, a passion for quality, and hands-on expertise in automation frameworks. You will be responsible for building and maintaining robust test suites for web services and APIs, ensuring the reliability, performance, and correctness of critical systems.

The ideal candidate combines a strong automation mindset with the ability to design and execute effective manual test strategies where needed, especially in complex service-oriented environments.

What You'll Do Here:
  • Design, implement, and maintain automated API and service-level test cases using Karate and Postman.
  • Collaborate with QA and engineering teams to define test strategies for new features and services.
  • Develop and maintain regression and smoke test suites to validate service health and system stability.
  • Perform manual exploratory and validation testing for complex backend workflows or non-automatable areas.
  • Execute and design backend performance validations using tools like JMeter, k6, or equivalent.
  • Validate data integrity and perform root cause analysis using logs, service metrics, and backend databases.
  • Run tests in Dockerized environments or local dev environments; contribute to test environment setup and configuration.
  • Participate in Agile ceremonies, sprint planning, and cross-functional collaboration.
  • Contribute to continuous integration (CI) and continuous testing (CT) pipelines as part of the QA automation lifecycle.

Experience We're Looking For:

Required Experience & Skills
  • 5+ years of experience in software quality assurance, with emphasis on backend systems and APIs.
  • Proven experience writing and maintaining tests in Karate Framework and Postman (including assertions, chaining, and scripting).
  • Strong understanding of RESTful services, including headers, auth flows, status codes, and payload validation.
  • Familiarity with Docker and containerized test setups.
  • Experience reading logs and debugging backend systems.
  • Solid manual QA background and exploratory testing experience for service-level validation.
  • Experience working in Agile/Scrum and using tools like JIRA, GitHub, and CI/CD pipelines.
  • Basic proficiency in reading code (e.g., Java, C#, JavaScript) to assist in triage and test alignment.

Bonus Experience:

  • Familiarity with Point of Sale (POS) Systems.
  • Experience with performance testing tools like JMeter, k6, or Locust.
  • Knowledge of MongoDB or other NoSQL databases.
  • Experience testing distributed or edge-deployed systems (e.g., POS terminals, IoT devices).
  • Familiarity with cloud platforms such as Azure or AWS.
  • Domain expertise in restaurant/POS systems and related workflows.

The Type of Team Player We Need:

  • A technical QA engineer who enjoys getting hands-on with code, APIs, and infrastructure.
  • Passionate about quality and delivering scalable, robust services.
  • Curious and self-driven: eager to experiment and iterate to find effective solutions.
  • Strong communicator who can articulate quality risks and collaborate across teams.
  • Comfortable working in a fast-moving, ambiguous environment with high expectations.
  • A team player who takes pride in raising the QA bar across squads.
