QA Engineer - Quantum Computing (m/w/d)

eleQtron develops and operates full-stack quantum computers based on trapped-ion technology. Quantum computing is a new computing paradigm rapidly approaching commercial viability. Our unique approach combines laser-cooled trapped ions with microwave control and tailored magnetic fields. Our next-generation computing machines under development will be able to find solutions to problems that are out of reach today, thus enabling new innovative products and services for a brighter future.

**We are looking for a QA Engineer (m/f/d) to join us in Hamburg or Siegen.

You will take ownership of quality across our software platform, from compilation services and the public API to the interfaces used by our operators and customers.

This is a _build-from-scratch role_ : there is no ready-made test suite waiting for you, and no expensive tool that does the thinking for you. You define _what_ good testing looks like here, and then you _build_ it.

You are as comfortable writing a test strategy on a blank page as you are writing the automation that implements it in code.

Responsibilities:

• Own the testing approach for our platform end-to-end: define what to test, at which level, and why
• Write test concepts from scratch — risk-based, covering unit, integration, system, and end-to-end levels, and turn them into running, maintained automation
• Build and own our test automation frameworks in code, integrated directly into our CI/CD pipelines, using your defined tooling
• Do the exploratory and manual testing that automation can't cover, and know where that line sits
• Establish quality gates, coverage expectations, and clear bug-reporting practices the whole team can work with
• Work closely with backend, platform, and hardware teams to test at the boundaries where software meets the machine
• Raise the testing literacy of the engineering team, so quality is a shared habit rather than a gate at the end
