Support Engineer

**About Quandela**: Quandela is a French deeptech company building Europe’s first general-purpose photonic quantum computers. Our machines are already available through the cloud, and now also delivered on-premise. Beyond hardware, we develop the full software stack: - **Perceval**, our open-source simulation library, - **Merlin**, our platform to program and run quantum algorithms, - **Cloud and on-site deployment** for academic and industrial clients. In 2024, as part of the **EuroQCS-France consortium (GENCI & CEA)**, Quandela is giving the European research community early remote access to a 6-qubit photonic quantum computer. This precedes the 2025 on-site deployment of **_Lucy,_** our 12-qubit system at CEA’s TGCC, marking a milestone that combines HPC and quantum in one hybrid infrastructure.

That’s why we are building a dedicated support cell. Your role will focus on the algorithms side - making sure codes and workflows actually run, feedback loops into R&D/Product - soon accompanied by a QPU-focused counterpart to cover the full stack. **Why this role matters ?** This isn’t “classic support.” You’ll be the single point of contact for GENCI/CEA researchers, ensuring that Europe’s first photonic quantum computer is usable, reliable, and impactful from day one. You will: - Help researchers run and debug algorithms on real hardware (photonic QPU) - Be the visible link between researchers, hosting teams, and Quandela’s R&D - Guarantee healthy collaboration and user satisfaction - Contribute to community building around Perceval and Merlin **Requirements**: **What you’ll do**: - Manage tickets on code execution, compilation, scripts, and performance. - Provide user training (1-to-1, workshops), maintain technical documentation. - Engage in weekly technical reviews and quarterly site meetings with hosting-site (HS/HLST) teams. - Ensure service continuity: when you are away, you coordinate handover. - Work closely with Algo, Software, Product, and Sales teams inside Quandela. - Collaborate with the upcoming Support QPU Engineer, creating a coherent “support cell.” - Channel structured feedback from users to R&D/Product, influencing our roadmap. **On-site presence** - 2 days a week at **CEA’s Très Grand Centre de Calcul (TGCC)** in **Bruyères-le-Châtel (Essonne)** - home of the Joliot-Curie supercomputer. Being close to the machine and the teams is what makes this support strategic and impactful. - The rest of the time : hybrid from Massy/Paris-Saclay / **How you’ll grow**: - **0-3 months**: onboarded on ticketing and HS workflows; handle simple tickets; draft first documentation; run initial training. - **3-6 months**: established as trusted SPOC; deliver clear docs; identify recurring pain points; propose fixes. - **6-12 months**: move from reactive support to proactive enablement: organize workshops, animate user community, propose KPIs and best practices for the support cell. Longer term (_for those who want it_) : potential evolution toward technical evangelism (external events, workshops) and/or leadership within a growing support team. **How success will be measured ?** - SLA on ticket response/resolution. - User satisfaction feedback (GENCI/CEA). - Contribution to 4 algorithms developed with CEA users in 12 months. - Adoption and active use of Merlin/Perceval. - Positive feedback from R&D/Product on quality of insights shared. / **Profile We Value**: **> Must-have** - Advanced Python (backbone of Merlin/Perceval and the scripts you’ll debug daily). - Familiarity with at least one quantum framework (Qiskit, Perceval, Cirq, etc.). - Strong debugging and documentation rigor. - Ability to explain technical issues clearly to researchers. - Professional English + conversational French (daily work with CEA and Quandela teams). **> Important (can grow, but appetite needed)** - Basics in HPC or applied maths/QML to follow user problems. - Experience in research contexts: e.g. helping a nuclear fusion researcher debug an algorithm that won’t run. - First exposure to training or documentation — or appetite for it. **> Bonus Points** - Experience in EuroHPC, CNRS, CERN, or other infrastructures. - Public-facing workshops or community events. Prior exposure to our quantum software ecosystems (Merlin/Perceval is a plus, but learnable). **> Backgrounds that could fit ?** - Researchers (applied maths, CS, physics) moving into client-facing roles, - Engineers from research infrastructures (e.g. EuroHPC). **Benefits** **Why Join ?** - Be part of Quandela’s first national quantum computer delivery (GENCI / CEA). - Work on a real QPU, support real algorithms, interact with top researchers. - Grow from support into community building, technical evangeli
