We are searching for a Quantum Systems Scientist to join our Systems team. This is a key role responsible for ensuring our quantum systems are continuously operational, scalable and robust, enabling cutting‑edge experiments and development across the business. You'll play a central role in building tools and systems that monitor and improve uptime, troubleshoot downtime and drive technical changes to enhance system reliability. Working with complex optomechanical systems, this role will combine diagnosis of faults with systems‑level thinking and collaborative problem solving across hardware and software teams.
Responsibilities
* System diagnostics and monitoring - Expand and refine hardware and software diagnostics; log and visualise key parameters; implement sensors and build dashboards to enable rapid fault‑finding.
* Downtime analysis and resolution - Analyse performance data to identify system bottlenecks or weak points; lead cross‑functional efforts to design and implement robust engineering fixes.
* Preventative and reactive maintenance - Own and schedule maintenance plans; support and mentor technicians; debug complex system issues as they arise.
* Process and tooling improvement - Improve documentation, procedures and training for system maintenance and upgrades, including trap changes and routine operations.
* Build tools and dashboards to surface key performance indicators and shape the procedures and infrastructure that support our growing number of quantum systems.
Qualifications
* High‑performing systems scientist with hands‑on experience in the design, build and operation of complex cold‑atom experiments.
* Proven track record designing, building and operating complex cold‑atom systems (e.g., ion traps, ultra‑cold atoms, optical clocks).
* Background in hardware‑focused experimental physics, with expertise in free‑space optics.
* PhD in a relevant discipline, ideally with post‑doctoral experience in an active research group.
* Strong communicator, able to collaborate across technical disciplines and coordinate with engineering and technician teams.
Desirable
* Programming experience in Python or ARTIQ.
* Experience automating and monitoring lab systems.
* Potential to grow into a leadership role as the team scales.
