Senior QA Engineer (Back End)

We are searching for talented people who are smart, bright, and like to improve the quality of software and software development processes.  

Who we are?  
At Wirex, we believe everyone should have access to the benefits of digital currency. We were the first to launch a crypto-enabled debit card, and we’re still ahead of the game — offering intuitive,  secure ways to buy, exchange, and spend crypto.   
We must be doing something right, because more than 7 million people across 130 countries are helping to 

change the world by using Wirex.     
Help us shape the future of digital finance!   

 
Type of Cooperation: B2B Contract.    
Location: Full remote (EU preferred, no sanctioned countries). 

Your job responsibilities will be: 
— Planning, preparation, and maintenance of test cases and test documentation.  
— Drive manual and automated API testing using Postman, Swagger, and related tooling.  

— Active involvement in the release process at all stages. 
— Collaboration with the development team: gathering information, reporting detected issues, and tracking their resolution.  
— Collaboration with analysts and developers in the feature requirements analysis process. 
—  Proactive work on optimizing the length of the test cycle. 
 

We are interested in: 
— 3+ years of hands-on Back-End / API testing experience—deep, day-to-day work at the service layer, not incidental API coverage alongside a UI testing role. 
— Solid experience in API testing tools (Postman, Swagger) and testing methodologies.  

— Hands-on experience in automated testing (C#/JavaScript/Go). 

— Proven track record in defect detection, documentation, and tracking on the Back-End side (but not limited to it.). 
— Experience with the Atlassian stack (Jira, Confluence) and version control platforms (Bitbucket or GitHub).  

— Knowledge of software development methodologies and the SDLC. 
— Ability to prioritize tasks, manage workload effectively, and identify risks to quality or timelines. 
— Excellent analytical and investigative problem-solving skills, capable of working independently.  
— Good English for documentation, Ukrainian/Russian for internal communication. 

Nice to Have 

— Experience in working with Web3, non-custodial wallets. 
— Knowledge of smart contracts and blockchain basics. 

 
Being a member of the Wirex team means:
