Quantum Engineer (Superconducting) - Member of Technical Staff

Role Overview

The Conductor Quantum team is building quantum superintelligence, focusing on automating the calibration and operations of superconducting-qubit systems. We aim to enable reliable, scalable, and useful quantum computing infrastructure. The role involves leading superconducting efforts while maintaining expertise across different modalities.

Key Responsibilities

• Device Packaging and Bring-Up

• Take superconducting-qubit devices from post-fab packaging to operational readiness.
• Own chip mounting and cryogenic assembly including wirebonding, shielding, and thermalization.
• Design or adapt microwave-compatible PCBs and enclosures for clean signal routing, filtering, and integration with control electronics.

• Experimental Setup and Measurement Infrastructure

• Build and maintain dilution refrigerator measurement setups including fridge wiring, line commissioning, and system verification.
• Specify, install, and test microwave and cryogenic hardware such as attenuators, filters, isolators, circulators, switches, and low-noise amplifiers.
• Develop robust procedures for cooldowns, thermal cycling, and system diagnostics to maximise uptime and repeatability.

• Qubit Calibration and Characterisation

• Run core calibrations including resonator and qubit spectroscopy, Rabi/Ramsey/echo, T1/T2, readout optimisation, and two-qubit gate calibration.
• Track key metrics like coherence, readout performance, and calibration time, and drive them upward over time.
• Debug and mitigate issues such as spurs, crosstalk, leakage, TLS effects, thermal population, and wiring or component failures.

• Lab Development and Instrument Control

• Lead setup and scaling of the experimental lab environment from equipment selection to day-to-day reliability.
• Write or adapt control software to interface with AWGs, microwave sources, DC sources, digitizers, and FPGA-based controllers.
• Build experiment orchestration and data practices so calibrations are reproducible and automatable.

• Collaboration and System Integration

• Work closely with physicists, ML engineers, and backend developers to integrate hardware, software, and data into a unified quantum control stack.
• Provide fast, practical feedback on usability, stability, and performance.
• Help translate lab realities into product requirements and roadmaps.

First 30 / 60 / 90 Days

• 30 Days

• Get fluent in the calibration software stack and understand how it maps to the hardware.
• Engage with customers and partners to understand how they use the platform today.
• Lead your first cooldown and characterisation run from resonator spectroscopy to single qubit randomized benchmarking.

• 60 Days

• Own a qubit bring-up cycle independently, from packaging to spectroscopy.
• Ship your first contribution to the automated calibration routine.
• Have a concrete proposal for the highest leverage things the team can do in superconducting qubit quantum computing.

• 90 Days

• Lead superconducting operations at Conductor.
• Have at least one calibration improvement in production that has measurably moved a key metric.
• Drive the superconducting qubit control and calibration roadmap at the Conductor.

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.
