# QA Engineer - Quantum Computing (m/w/d)eleQtron GmbHVia arbeitnowSiegen, DEPubliée il y a 4h## Description du poste**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 **Required Skills:*** 3+ years in software quality assurance, with real ownership of test strategy, not only executing predefined test scripts* Ability to design a test concept for an unfamiliar system: choosing the right test levels, techniques, and priorities from first principles* Confident programming ability (Python preferred), enough to build and maintain automation yourself rather than depend on record-and-playback tools* Hands-on experience with open-source testing frameworks (e.g. pytest, Playwright, Selenium) and integrating tests into CI/CD* Solid grounding in testing fundamentals: test design techniques, the test pyramid, API testing, and when to automate versus test manually* A generalist, tool-agnostic mindset, you pick the right approach for the problem, not the one tool you already know* Ability to collaborate effectively with experimental physicists and engineers* Strong adaptability and a quick learning mindset* Good proficiency in English (written and spoken)**Nice to have (Bonus)*** Experience setting up a QA function or test strategy in an early-stage or greenfield environment* Testing distributed systems, APIs, or cloud-native services* Performance, load, or security testing experience* Exposure to hardware-in-the-loop or lab/control-software testing* ISTQB certification, or an equivalent grounding in test theory you actually apply* Prior exposure to quantum computing or other deep-tech domains**What you can expect from eleQtron:*** **Competitive salary:** We value our team members and therefore provide remuneration that reflects this, additionally rewarding achievements* **Flexible working hours**: We offer personal freedom through a variety of flexible work schedules* **Team spirit:** In our international and diverse team, and with our regular team events, having fun at work is simply part ...
