Top Tech Jobs & Startup Jobs

Support full-cycle intern recruitment, onboarding, HR administration, ATS maintenance, recruitment reporting, and employer branding. Partner with hiring managers on staffing needs and recruitment best practices. Develop university relationships, organize campus events, and build internship talent pipelines. The role requires French and English communication, HR or recruitment experience, and enrollment in a qualifying master’s program with an internship agreement.

Support the CTO and CSO by coordinating technical and scientific strategy across research, product, and engineering. Track major initiatives, milestones, dependencies, and risks; prepare strategic briefings and leadership reviews; improve organizational processes and communication; facilitate cross-team execution; and lead strategic projects that help scale the technical organization.

Characterize fabricated photonic integrated circuits through optical and electrical die-level measurements. Operate and maintain laboratory setups, ensure calibration and traceability, analyze device performance, troubleshoot experiments, and develop Python automation and data-analysis scripts. Improve qualification workflows, documentation, reproducibility, and statistical monitoring across fabrication batches. Collaborate with simulation, design, packaging, and cryogenic teams to support device selection and scalable quantum hardware integration.

Design and simulate photonic integrated circuit components, including waveguides, interferometers, beam splitters, phase shifters, and reconfigurable elements. Translate simulations into manufacturable GDS layouts, prepare foundry tape-outs, analyze characterization data, and refine designs based on fabrication feedback. The role also contributes to design-for-manufacturing methodologies, high-speed photonic integrations, and scalable quantum processor architectures.

Lead foundational IT systems across Quandela’s headquarters and international subsidiaries. Responsibilities include user and device support, identity and network administration, cloud and application management, subsidiary onboarding, vendor coordination, IT governance, security hardening, monitoring, sovereign-cloud migrations, and responsible AI adoption. The role combines technical leadership, hands-on contribution, cybersecurity improvement, business-process partnership, and consistent international IT service delivery.

Develop and evaluate classical, quantum, and hybrid machine-learning methods for quantum computing. Responsibilities include designing models, improving quantum-system calibration and control, benchmarking methods, contributing to the MerLin framework, publishing research, presenting findings, collaborating with academic and multidisciplinary teams, and mentoring junior researchers.

Perform hands-on optical characterization of single-photon sources in cavities, optimize excitation and pulse shaping, measure KPIs (lifetime, indistinguishability, brightness, purity, spin), automate instrumentation and data processing with Python, work with cryogenics/vacuum and collaborate with fabrication and production teams to improve procedures and reproducibility.
