Quality Engineer

About CloudX

About The Team

What you'll do

• The SDK & Ad Rendering: You’ll design and maintain test suites that validate how our SDK behaves across a fragmented world of devices and OS versions. You’ll build automated ways to verify that ads don’t just "load," but render perfectly, performantly, and without breaking the publisher’s app.
• Infrastructure & CI/CD: You’ll work alongside the backend team to toughen up our pipelines. Whether it’s improving our test coverage or building custom tooling to make our CI faster, your goal is to help us ship daily with zero anxiety.
• Defining the Standard: You’ll be the internal champion for testing best practices. You’ll help other engineers write better tests and ensure that "quality" is a shared mindset, not a separate department.

Who you are

• You’re a builder, not just a tester. You don't just write test plans; you write code. You’re comfortable diving into production environments, reading backend logic, and building automation frameworks from scratch.
• You have Startup Grit. You understand that in an early-stage company, we have to make trade-offs. You know exactly when a 5-minute manual check is enough and when we need a "bulletproof" automated suite to prevent a catastrophe.
• You write for humans and agents. Since we work asynchronously, your writing matters. You can explain a complex race condition in a way that’s easy to grasp, and you write bug reports that engineers actually look forward to reading.
• You are AI forward: you are actively experimenting with or using AI as part of your testing practice. You don’t send vibe-coded slop to your teammates to review, but you use AI appropriately to achieve great results.
• You take it personally. When a bug hits production, it bothers you. You’re proactive about identifying risks and edge cases that others might overlook in the rush to ship a feature.
• Systems Thinker. You can visualize how a change in a backend API might ripple out and break a specific ad format on an old Android device three layers deep.

Things that will make you standout

• Mobile SDK Experience: If you’ve dealt with the pain of mobile fragmentation and SDK integration before, you’ll fit right in.
• AdTech Background: If phrases like "RTB," "Vast tags," or "Auction latency" mean something to you, you’ll have a massive head start.
• Performance Engineering: Experience with load testing or benchmarking high-throughput systems is a huge plus.
