About Push Security
At Push Security, we’re on a mission to defend organizations where work and attacks actually happen: in the browser. For decades, security tools focused on endpoints and networks, leaving the browser, where everyone now works, as a massive blind spot that attackers are exploiting. We are changing that by defining the future of Browser-based Threat Detection and Response. Built by world-class red and blue team experts, Push gives defenders the real-time visibility and control needed to stop modern threats.
Role Summary
We’re searching for an experienced QA Engineer who will thrive in a modern startup. You’ll join a small, fast-moving team responsible for ensuring our platform and browser extension work flawlessly. The extension protects users from phishing and identity-based attacks and monitors authentication behavior across thousands of web apps. You’ll own the quality process of this product - building tests, improving frameworks, and ensuring our protections remain reliable every day.
Key Responsibilities:
- Build and maintain end-to-end tests using tools like RainforestQA
- Design and own test strategies, frameworks, and coverage plans
