About the role

Ubiquiti Prague is looking for a QA Engineer who wants to build products that millions of people rely on every day. This role is much more than executing test cases. You’ll evaluate new features from a user’s perspective, challenge product decisions, identify hidden risks, and help ensure that every release meets the quality our customers expect. Sometimes that means finding a critical bug. Sometimes it means recognizing that a workflow is confusing, a feature leads to a dead end, or a release simply isn’t ready. You’ll work closely with product managers, designers, and software engineers throughout development - not just at the end. Your feedback will directly influence product decisions and help prevent issues before they reach customers.

We’re looking for someone who enjoys understanding how things work, naturally questions assumptions, and isn’t afraid to ask, “Does this really make sense for the user?” Basic networking knowledge is important, but curiosity, critical thinking, and attention to detail matter even more. We value people who take ownership of quality, think independently, and care about building products they would be proud to use themselves.

Candidates should be prepared to work from our Prague office at least two times per week.

Responsibilities:

Test UniFi desktop and mobile applications on iOS, Android, Windows, Linux, and macOS

Evaluate new features from the user’s perspective and identify usability, functionality, and quality issues

Discover, reproduce, document, and verify software defects

Analyze customer feedback and community reports to reproduce and investigate reported issues

Collaborate with developers and product managers to improve product quality and release readiness

Identify opportunities to improve workflows, user experience, and overall product quality

Continuously learn about networking, our products, and new technologies

Must have:

2+ years of experience testing modern web, desktop, or mobile applications

Solid understanding of computer networking (TCP/IP, common protocols, and network services)

Strong analytical thinking and problem-solving skills

Excellent attention to detail with a strong sense of ownership and responsibility

Experience working with Jira and Confluence

Basic knowledge of Linux/Unix, including SSH and common shell commands

Good written English for daily communication and documentation, and fluency in Czech

Nice to have:

Experience with Git and version control workflows

Experience with performance or stress testing

Programming or scripting experience (e.g., Bash , Python, or similar)

Experience using AI tools to improve testing efficiency, such as issue investigation, log analysis, or exploratory testing

Curiosity about new technologies and a willingness to continuously improve testing processes

Benefits:

Competitive salary and 5 weeks of vacation per year

Discretionary bonuses based on individual performance

Flexible working hours, home office

Access to all the latest Ubiquiti products and prototypes for home use and tests
