Top Tech Jobs & Startup Jobs

Owns US HR, payroll, benefits, onboarding, offboarding, employee records, employment documentation, financial administration, vendor coordination, and compliance. Supports immigration processes, team events, and continuous improvement of HR, finance, and administrative operations for a growing US subsidiary while collaborating with France-based teams.

Own full-cycle recruitment for tech and business roles while optimizing ATS, recruiting tools, data and processes. Partner with hiring managers, build sourcing strategies, track recruiting KPIs, create dashboards, improve candidate experience, and contribute to employer branding and talent attraction.

Build and manage high-impact industrial partnerships across semiconductors, electronics, manufacturing, defense, cryogenics and quantum sectors. Lead executive-level negotiations, structure long-term collaborations, accelerate industrialization and supply-chain resilience, represent the company at industry events, and work cross-functionally with Engineering, Product, Legal, Finance and Procurement to maximize partnership value and commercialization opportunities.

Designs, builds, and validates RF control electronics and characterization systems for superconducting quantum processors. Responsibilities include developing custom RF hardware and PCB front-ends, creating measurement plans and automated Python-based validation, upgrading RF/DC systems, troubleshooting instrumentation and electronics, and performing root-cause analysis. The role collaborates with physicists, software engineers, and quantum hardware infrastructure teams while documenting designs and test results.

Designs and integrates electronics systems for superconducting quantum computers, including custom PCBs, racks, cryostats, cabling, and instrumentation. The role includes validation testing, troubleshooting across electronic and mechanical systems, supplier evaluation, hardware architecture collaboration, and technical documentation. Candidates need strong hands-on electronics, PCB design, lab instrumentation, Python automation, sourcing, and communication skills, with French proficiency preferred.

Build semiconductor physical-design infrastructure for scalable superconducting quantum chips. Responsibilities include developing PDKs, layout generators, hierarchical methodologies, DRC/LVS/PEX verification, parasitic extraction, mask generation, tape-out data preparation, and EDA toolchain automation. The role requires replacing manual layout with programmatic, tile-based flows capable of supporting millions of design elements and wafer-scale or multi-chip architectures.

Manage end-to-end procurement for technical infrastructure projects spanning nanofabrication and cryogenics. Partner with engineering and experiments teams to define requirements, identify solutions, negotiate with suppliers, manage budgets and timelines, develop supplier relationships, expand the supplier network, improve procurement processes, and monitor technical markets. The role requires 5+ years of industrial or technology purchasing experience, strong sourcing and negotiation skills, organizational ability, autonomy, and fluency in French and English.

Lead the Monitoring and Recalibration team responsible for keeping quantum processing units operational. Own measurement workflows, dashboard data quality, validation criteria, product metrics, production service reliability, and system efficiency. Set technical direction, establish software engineering standards, grow the interdisciplinary team, and collaborate with experimental and software leaders to deliver internal and customer-facing monitoring products.

Develop and qualify 3D integration technologies for superconducting quantum processors, including flip-chip bonding, TSVs, airbridges, multilayer wiring, and wafer-level assembly. Coordinate integration testing, establish scalable procedures, investigate technical anomalies, assess interconnect reliability, and collaborate with fabrication, packaging, foundry, and equipment partners. The role requires hands-on cleanroom experience and end-to-end process development, from test-vehicle design through experimental validation and go/no-go decisions.

Develop low-level software, drivers, and hardware abstraction layers for quantum-control electronics, including signal generators, AWGs, digitizers, and FPGA instruments. Define reliable hardware/software interfaces, synchronization mechanisms, and low-latency communication systems. Collaborate with physicists and researchers, guide architecture and technical strategy, lead reviews, and mentor engineers while supporting production-grade quantum experimentation platforms.
