Qilimanjaro is building full-stack superconducting quantum computers, from QPUs and cryogenic infrastructure to control electronics, racks, cabling, instrumentation and deployment software. Our Systems & Engineering division is what turns a quantum processor into a complete, reliable, scalable machine.
We are a small, hands-on team. Every hire shapes what we become.
Why this role exists The electronics layer of a quantum system (signal chains, grounding, shielding, filtering, low-noise analog, power integrity, PCB design) is one of the main determinants of qubit performance and system reliability. As we scale toward 50-qubit systems and beyond, this layer has to be designed from first principles, not grown from lab habit.
Today our junior engineers are learning fast and carrying real work. What we are missing is a seasoned electronics engineer who designs the signal chain right before it reaches the bench, who simulates signal integrity before a board is fabricated, architects grounding instead of guessing it, anticipates the scaling problem we haven't hit yet,



and raises the technical floor of the whole team.
You will become the technical authority for the electronics layer : the person the team turns to for "is this signal chain correct, quiet, and scalable?" and the person who makes sure the answer is documented, not tribal. You will set the standards and review others' designs, and directly mentor one to two junior engineers, with a clear path to lead the department as the team grows.
Signal-chain architecture: Define and document how signals are generated, conditioned, filtered, routed and shielded from the electronics rack to the QPU, both the DC / flux-bias path (DC to a few hundred MHz) and the RF / readout path (a few GHz). Architecture first, validation second.
Grounding and shielding by design : Define the grounding topology, return paths, chassis isolation and rack-level shielding for each system, documented, justified and repeatable, not resolved ad hoc
