Start your adventure with Zip 

We’re looking for a Senior Engineer in Test who sees quality as a core part of building great products, not just something that happens at the end.

In this role, you’ll work closely with engineers, product, and platform teams to build reliable, scalable test systems across our web, mobile, and backend platforms. You’ll take ownership of quality end-to-end, helping ensure we ship quickly without sacrificing confidence.

This is a great fit for someone who enjoys solving complex problems, improving how teams work, and bringing a thoughtful, practical approach to quality in a fast-moving environment.

Interesting problems you’ll get to solve

• Own quality across one or more product areas, from early design through release
• Partner closely with engineers and product teams to catch issues early and improve how we build
• Identify gaps in coverage or process and proactively drive solutions

• Design, build, and maintain test frameworks across:
• Web (TypeScript, Playwright, Appium)
• Mobile (iOS/Android)
• Backend APIs and services (BDD, Cucumber)
• Improve reliability and reduce flakiness in automated tests
• Continuously refine testing approaches to keep up with product and platform changes

• Improve CI/CD pipelines to balance fast feedback with high confidence
• Define and track meaningful quality metrics that reflect real product health
• Help teams make better decisions by providing clear signals, not just more data

• Champion quality as a shared responsibility across teams
• Lead discussions around test strategy and system design
• Mentor engineers and help raise the bar for how we think about quality

• Explore and apply new approaches to testing, including automation and intelligent tooling
• Use data and patterns to prioritize testing efforts and improve efficiency
• Continuously look for ways to reduce manual effort and improve coverage

What you’ll bring to the team 

• 8+ years of experience in quality engineering, test automation, or software engineering
• Strong experience with JavaScript/TypeScript in a testing or development environment
• Hands-on experience with frameworks like Playwright, Cypress, or WebdriverIO
• Experience testing APIs, distributed systems, and modern web applications
• Familiarity with CI/CD pipelines and integrating testing into release workflows

• You take ownership and follow things through to completion
• You’re proactive — you spot problems early and work to solve them
• You’re comfortable working in ambiguity and bringing structure where needed
• You focus on outcomes and impact, not just activity
• You care deeply about building high-quality products and improving how teams work

• Experience with mobile automation and tools like BrowserStack
• Exposure to newer approaches in test automation and intelligent tooling
• Experience working closely with cross-functional teams in fast-paced environments
