‍You will design and build test automation frameworks from the ground up, apply developer-level programming to create scalable, reusable test code, and drive comprehensive quality engineering practices (including performance testing and API validation) that go beyond conventional manual QA.

• Design and build test automation frameworks from scratch (not just utilizing existing frameworks)

• Write developer-level test code in Java, applying OOP principles and design patterns to ensure scalability and reusability

• Conduct performance & load testing (scenario design, traffic simulation, and analysis of bottlenecks, response time, and memory leaks)

• Perform strong API testing (REST/SOAP) — including status code, data accuracy, and integration flow validation

• Write SQL queries to validate data integrity

• Integrate automated tests into CI/CD pipelines for continuous testing

• Understand and apply various testing types: unit, integration, functional, regression, and performance testing (white-box vs black-box)

• Study application data flow through technical documentation to design accurate test scenarios

• Calculate user projections, estimate RPS/TPS, and prepare pre-requisites before executing performance tests

• Minimum 3 years of experience as an SDET, Test Automation Engineer, or Software Engineer focused on quality engineering

• Strong developer-level Java programming skills, including solid understanding of OOP and design patterns for building scalable, reusable test code (not just scripting)

• Proven ability to design and build test automation frameworks from the ground up

• Experience with performance & load testing using JMeter — scenario creation, traffic simulation, and result analysis

• Strong API testing skills (REST/SOAP) using tools such as Katalon, REST Assured, Postman, or SoapUI

• Database & SQL proficiency (e.g., MySQL, PostgreSQL, or Oracle) for data integrity validation

• Experience integrating automated tests into CI/CD pipelines (Jenkins, GitLab CI)

• Familiar with version control: Git/Bitbucket/GitLab

• Solid understanding of testing concepts: unit, integration, functional, regression, and performance testing; white-box vs black-box testing

• Able to interpret application data flow from technical documentation (e.g., Confluence)

• Able to calculate user load projections, estimate RPS/TPS, and prepare performance test pre-requisites
