Company

hirify.global is scaling quantum computing technology from scientific proof-of-concept work toward reproducible, automated systems capable of supporting a quantum advantage demonstration.

What you will do

• Own the end-to-end measurement chain and error budget for quantum gates, including cryogenic DC and microwave control and readout chains.
• Manage signal budgets across cryogenic setups, covering noise temperature, insertion loss, crosstalk, dynamic range, photon number, TWPA calibration, and magnetic-field measurements.
• Quantify noise impacts on qubit coherence and fidelities, calibrate pulses, and design and test measurement protocols with quantum physicists.
• Build dashboards for qubit and setup performance, improve figures of merit, ensure homogeneous performance, and provide quantitative feedback to R&D teams.
• Drive setup upgrades and installations from specification through commissioning, acceptance testing, supplier selection, qualification, and validation.
• Document measurement practices, train physicists and engineers, and maintain common standards across setups.

Requirements

• PhD in experimental physics or metrology and at least two additional years of experience as a post-doctoral researcher or in industry.
• Proven experience building, characterizing, and optimizing complex experiments.
• Strong experience with RF experiments, including pulse sequencing, phase noise, and IQ up/down conversion.
• Strong experience with dilution refrigerators, including cryogenic wiring, thermalization, shielding, and fault diagnosis.
• Strong analytical skills and a solid understanding of statistical methods.
• Rigorous and well organized, with high scientific standards and the ability to determine when results are sufficiently reliable for action.
• Fluent Python skills for autonomous experiment control, data processing, and reusable tool development.
• Clear written and verbal English communication across technical and non-technical audiences.
• Relevant backgrounds may include superconducting or semiconductor qubits, quantum sensing or communications, atomic or optical metrology, astronomy, particle physics instrumentation, or similar fields.

Nice to have

• Experience combining hands-on laboratory work with industrial challenges.
• Interest in quantum computing, quantum technologies, and landmark scientific results.

Culture & Benefits

• Collaborative international team of more than 80–90 people spanning resonator fabrication, nanotube engineering, software, theory, nanofabrication, and quantum electronics.
• Stock options for every employee through BSPCE/ESOP.
• Conference travel, meal vouchers, mental health support, and an annual training and learning budget.
• Sabbatical leave after two years with the company.
• Office culture in two Paris locations with team lunches, offsite events, and Friday breakfasts.
• Values include scientific excellence, integrity, curiosity, care, diversity, and commitment to meaningful quantum technology.
