The Team

Who We Are Looking For

Perks

• Quantum Device Fabrication and Bring-Up

  • Take quantum dot devices from the lab bench to operational readiness.
    • Perform wire bonding, device packaging, and chip mounting for cryogenic testing.
    • Design and fabricate custom PCBs for signal routing, filtering, and integration with control electronics.

• Experimental Setup and Measurement Infrastructure

  • Build and maintain cryogenic measurement setups including dilution refrigerators, fridge wiring, and line testing.
    • Specify, install, and test hardware components such as low-noise amplifiers, DC lines, filters, bias tees, and microwave components.
    • Develop robust procedures for cooldowns, thermal cycling, and system diagnostics.

• Device Tuning and Characterisation

  • Run transport, rf-reflectometry, and charge sensing measurements to identify quantum dot and spin qubit formation, tune gate voltages, and extract stability diagrams.
    • Optimise device configurations through iterative tuning.
    • Collaborate with software and ML teams to close the loop on automated calibration routines.

• Lab Development and Instrument Control

  • Lead setup and scaling of the experimental lab environment.
    • Define lab requirements, spec out measurement equipment, and manage lab logistics.
    • Write or adapt control software to interface with waveform generators, DACs, and lock-in amplifiers.

• Collaboration and System Integration

  • Work closely with physicists, ML engineers, and backend developers to integrate hardware, software, and data pipelines into a unified quantum control stack.
    • Provide feedback on usability, stability, and performance from a hardware and systems perspective.

First 30 / 60 / 90 Days

• 30 Days: Wire bond a device, load it into the dilution fridge and perform a full cooldown.
  • Sit with customers to see where the platform breaks down for them. Identify one friction point and propose a fix.
• 60 Days: Run and automate standard qubit calibration routines and two-qubit gate routines.
  • Write and adapt control software for arbitrary waveform generators, digital to analogue converters, and lock-in amplifiers.
• 90 Days: Be the team lead for spin qubit quantum hardware. Shape what we build next: which qubit architectures we prioritize, what measurement capabilities the lab needs, how we close the gap between manual characterization and fully automated calibration at scale.

The Team

• We are a small, passionate founding team of quantum physicists, hardware engineers, and machine learning experts.
  • Our founders, Brandon and Joel, met each other at Oxford during their PhDs working on AI for quantum computing, where they saw first-hand that calibration and control is a core bottleneck to scaling quantum computers.

Who We Are Looking For

• High intelligence, high energy, and high integrity.
  • Obsessive about noise floors.
  • Relish the challenge and physical chaos of a scaling hardware lab.
  • People who are hungry to change the world and do not need to be told what to do next.

Perks

• Free healthcare, dental, and vision
  • Work on the most important technical problem of our generation.
