Quantum Optics Scientist - Spin-Based Quantum Systems

Location: On-site at the IPVF campus in Palaiseau, Île-de-France, France, within the Paris-Saclay research ecosystem.

Company

hirify.global is a European deeptech scale-up developing modular, scalable and energy-efficient photonic and spin-optical quantum computers accessible through the cloud and on-premises, with hardware and software spanning semiconductor quantum emitters, photonic processors, quantum control systems and algorithms.

What you will do

• Design, develop and optimize optical experiments involving spin-photon sources.
• Implement optical control schemes for spin initialization, readout and manipulation.
• Characterize spin coherence, operation fidelity and entanglement quality.
• Independently drive experimental investigations, structure scientific activities, prioritize milestones and troubleshoot complex systems.
• Develop and validate photon-mediated spin-spin entanglement protocols.
• Collaborate with theory, electronics and semiconductor technology teams to improve robustness, reproducibility and system performance and translate results into demonstrators and technological building blocks.

Requirements

• PhD in Spin Physics, Quantum Optics or a related field.
• 4+ years of postdoctoral or equivalent R&D experience; researchers completing a substantial postdoc may also be considered if they demonstrate scientific maturity, technical ownership and readiness for broader responsibilities.
• Hands-on experience with spin-based quantum systems, including control, readout or coherence measurements.
• Proven autonomy in designing, optimizing and troubleshooting complex quantum experiments.
• Strong understanding of quantum optics, spin coherence and experimental measurement techniques.
• Ability to lead scientific activities and make independent technical decisions.
• Comfort collaborating across experimental, theory and engineering teams.
• People management experience is not required; the role requires scientific ownership, technical problem-solving and knowledge sharing.

Nice to have

• Photon-mediated entanglement protocols and multi-spin architectures.
• Semiconductor quantum emitters, quantum dots and spin-photon interfaces.
• Advanced optical control, cryogenic platforms and fast electronics.
• Experimental qualification, system integration and technology transfer.
• Experience bridging academic research and industrial R&D.
• Experience coordinating scientific projects or mentoring researchers.

Culture & Benefits

• Work on evolving spin-based platforms, open scientific challenges and future fault-tolerant quantum computing architectures.
• Profit-sharing and a company savings plan.
• 50% coverage of public transport subscription and an annual sustainable mobility bonus.
• Fully covered Alan health insurance.
• Childcare support through nursery access or contribution to childcare expenses.
• Gym and sports subsidy, meal subsidies and referral bonuses of €1,000 for junior and €2,000 for experienced candidates.

Hiring process

• Talent Acquisition Interview, followed by a Hiring Manager Interview.
• Technical discussion and presentation of previous research work, followed by a team meeting and scientific discussion.
• Reference checks and offer.
