About Cowchain 
Cowchain is a Web3 development company behind PixelVerse, StepApp, RetroBridge, Hybrid, Tenet, and 150+ other blockchain products with $180M+ combined market cap. We're a team mostly based in Ukraine, with some across Europe, fully remote. We build across DeFi, GameFi, cross-chain bridges, AI agents, NFT platforms, and Telegram mini-apps.

We look for people who take ownership, think deeply, and enjoy figuring things out on their own. No unnecessary hierarchy—you talk directly to the founders when it matters. We value what you bring over how long you've been around.

About the role 

We're looking for a Manual QA Engineer to join our team and help us ship quality products across web, mobile, and Web3 platforms. This is a Junior+ role—we don't chase titles or years of experience. 

We want someone proactive, curious, and ready to grow fast. You'll work on a mix of client projects and internal products, testing everything from dApps and crypto wallets to mobile games and AI-powered tools. 

What you'll do 

- Test web, mobile, and Web3 products across the full QA cycle: functional, regression, smoke, sanity, exploratory 

- Read PRDs and user stories, then design and write test cases on your own

- Write bug reports the dev team can act on without follow-up: steps to reproduce, expected vs actual, severity/priority, environment 

- Test APIs in Postman alongside UI testing - because half the bugs live below the surface 

- Work closely with developers, PMs, and designers

- Use AI tools as part of your daily workflow (test case generation, bug report drafting, edge case brainstorming)

- Own the quality of what you test, flag risks, push back when something isn't ready, advocate for the user

What we're looking for 

- 1+ year of hands-on manual QA experience 

- Solid testing fundamentals: clear difference between functional, regression, smoke, and sanity testing 

- Can take a PRD or user story and turn it into a proper set of test cases independently 

- Writes structured bug reports: steps, expected vs actual, severity/priority, environment

- Comfortable with test case management tools 

- Confident with Postman: sending requests, checking status codes and response bodies, building collections 

- Understands REST basics: HTTP methods, headers, auth (Bearer token and API key) 

- Can read API documentation and test edge cases through Postman, not only through the UI 

- Open to AI tools—you don't have to be an expert, but you should be ready to make them part of your daily work 

Nice to have 

- Web3 basics at user level: wallet, private key, transaction, network, gas

- Hands-on experience with MetaMask or any other Web3 wallet 

- Understanding of testnet vs mainnet 

- Mobile testing experience—understands what makes it different from web (devices, OS versions, network conditions, store guidelines) 

- Basic SQL for data verification 

- Prior experience using AI assistants (ChatGPT, Claude, Gemini) for QA tasks 

What we offer 

- Fully remote work from anywhere

- Paid vacation and sick leave 

- AI tool subscriptions (ChatGPT, Claude, Gemini) for your daily work - we're an AI-first team and we expect everyone to use them 

- Internal knowledge sharing and Personal Development Plans 

- Individual onboarding tailored to your role and project 

- Real product variety across dApps, games, AI agents, and mobile apps
