🚀 We're Hiring: Senior Test Engineer | Warsaw, Poland

Are you passionate about breaking things to make them better? Do you dream in JUnit, get excited about AI in testing, and understand how blockchain ticks? If you're a seasoned test engineer ready to make an impact — we want to meet you.

🌍 Location: Warsaw, Poland

📅 Experience: 5+ years

💼 Type: Contract, Full-time | Hybrid

🔧 What You’ll Be Doing:

Lead end-to-end test strategy and execution across multiple systems and platforms

Own both black box and white box testing — from user workflows to the inner workings of APIs and code

Write clean, maintainable unit and integration tests in Java (JUnit, Mockito, etc.)

Dive deep into system design discussions to influence architecture with quality in mind

Use the latest AI tools to automate, accelerate, and elevate testing

Work closely with developers, designers, and blockchain engineers to deliver bulletproof software

Ensure our blockchain-based solutions are rock-solid and secure

🧠 What We’re Looking For:

5+ years of hands-on experience in software testing / QA

Strong command of Java and test frameworks like JUnit / Mockito

A solid grasp of system architecture and how things connect under the hood

Understanding of blockchain concepts (distributed systems, smart contracts, consensus mechanisms)

Curiosity and drive to explore AI-based testing tools

Attention to detail, a love for quality, and a bias for action

Based in Warsaw or open to working from our Warsaw office

💡 Why Join Us?

Be part of a future-facing team working with AI and blockchain

A culture that encourages experimentation, ownership, and continuous learning

Work on projects with real impact in a collaborative environment
