About Performance Tester roles
Performance Tester is a mid-level title within software quality assurance analysts and tester work in the software engineering space. Day to day, the role draws on Cypress, Selenium WebDriver, Postman, and SQL. Hiring teams evaluate candidates on system design trade-offs, code quality, debugging under pressure, and how you ship changes reliably. Because this title specializes in performance, examples drawn from performance work will carry more weight than general software quality assurance analysts and tester stories.
Prepare both halves of the process here: tighten your resume around the systems you shipped, their scale (users, requests, latency), and the engineering decisions behind them, then rehearse interview answers that walk through a situation, the decision you made, and a measurable outcome. A representative interview question for this field: “How do you decide what to automate versus keep as manual testing?” Many candidates bring a background such as B.S. Computer Science.
