Job description

SDET (Software Development Engineer in Test)

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.

Role Summary

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.

Key Responsibilities

• 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

Requirements

• 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
• Willing to work onsite (WFO) in West Jakarta

Work Arrangement

• Employment type: Contract
• Contract duration: 12 months (extendable)
• Location: West Jakarta
• Work type: On-site/Work from Office (WFO)
• Expected join date: August 2026 (immediate joiners are preferred)
