Senior Site Reliability Engineer – Quantum Computing (f/m/d)
Job Description
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 Senior Site Reliability Engineer to drive the reliability, scalability, and operability of the software systems powering our trapped-ion quantum computers.
Responsibilities:
As a Senior Site Reliability Engineer – Quantum Computing (f/m/d), you will take end-to-end responsibility for the reliability, stability, and operability of our software that operates our quantum computers. You will act as a technical authority for system reliability, shaping how our quantum computers are operated, monitored, and evolved in production-like lab environments. This is an on-site position in Siegen or Hamburg, working closely with software engineers, firmware developers, physicists, and hardware engineers in an interdisciplinary environment.
