Quantum Engineer (Spin) - Member of Technical Staff

Conductor Quantum is building quantum superintelligence.

Quantum superintelligence is an AI that uses quantum computers to surpass the capabilities of humanity's greatest minds. We are closer to that inflection point than most people realise. Frontier models are approaching general intelligence, and AI can already generate quantum circuits faster than humans can write them. The question is no longer whether quantum and AI converge; it is who builds the infrastructure to make that convergence reliable, scalable, and useful.

That infrastructure starts with the hardware. The biggest bottleneck in quantum computing today is not qubit count; it is the manual configuration that keeps those qubits from being usable. Our software automates calibration and operations for spin and superconducting-qubit systems, turning raw cryogenic hardware into a stable, ready-to-run platform accessible through a simple chat interface. By solving that bottleneck, we are enabling thousands, and eventually billions, of qubits to operate reliably at scale.

The result is a quantum computer as easy to use as ChatGPT. The first billion users are coming. The majority, we believe, will be AI agents.

Why Now

Today, AI generates production code faster and more reliably than most of the world's software engineers. Code is math; math is an instruction set; an instruction set is a quantum circuit. AI is already generating quantum circuits. It just needs reliable hardware to run them on, well-calibrated qubits to utilise, and a feedback loop tight enough to discover new algorithms autonomously.

The world's most capable AI models are being pointed at B2B SaaS. We are pointing ours at the frontier of science.

Role Overview

You will work across the full quantum stack: from taking a chip fresh out of the foundry all the way to hosting it online as a platform that human researchers and AI agents can build on. This is a high-impact, high-ownership role. You will define best practices, influence product strategy, and help lay the foundation for Conductor Quantum's culture and growth.

Key Responsibilities

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. Design printed circuit boards for signal routing and filtering. Spec out and procure the hardware the lab needs next.

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.

This is your opportunity to do the best work of your life as part of that founding team.

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.
