HPC & Quantum Solutions Architect (Presales) in Massy

Quandela is Europe's leader in photonic quantum computing.

We design and deliver high-performance quantum processors—available on-premise or via cloud access—to enable organizations to explore quantum advantage in optimization, simulation, and machine learning.

As adoption accelerates, we are expanding our technical organization with a senior HPC & Quantum Solutions Architect who will guide customers in designing next-generation hybrid HPC-quantum infrastructures.

As an HPC & Quantum Solutions Architect at Quandela, you will define and design end-to-end hybrid architectures that seamlessly integrate quantum computing into complex HPC environments.

You will partner with enterprise, HPC centers, and research institutions to shape technical strategy, architect hybrid workflows, and provide deep technical leadership across presales, solution design, deployment, and early adoption.

Key Responsibilities

• 1. Customer Architecture Leadership
• Lead in-depth technical discovery with HPC centers, industry R&D teams, national labs, and enterprise architecture groups.
• Assess existing HPC infrastructures, workloads, data flows, interconnects, and operational constraints.
• Identify hybrid HPC-quantum opportunities and propose strategic architectures aligned with customer objectives.
• 2. Hybrid HPC-Quantum Architecture Design
• Architect end-to-end solutions integrating Quandela's photonic quantum processors, control electronics, networks, simulators, cloud services, and on-prem orchestration.
• Define system sizing, performance models, workload placement strategies, and hybrid workflow pipelines.
• Produce high-quality architecture documents, diagrams, and design specifications for decision-makers and technical stakeholders.
• 3. Technical Strategy & Advisory
• Serve as a trusted advisor to CTOs, HPC leaders, and scientific teams on hybrid computing strategy, roadmaps, and operational models.
• Recommend integration patterns (Slurm, Kubernetes, PBS), networking designs (Infini Band, Ethernet), and accelerator strategies.
• Guide customers through infrastructure readiness, security considerations, and operationalization.
• 4. Advanced Prototyping, Benchmarks & POCs
• Design and oversee proof-of-concepts, benchmarks, and technical evaluations demonstrating hybrid performance gains.
• Work with HPC and application engineers to build custom workflows and domain-specific demos.
• Support pilot deployments—including on-premise quantum installations and hybrid cloud integrations.
• 5. Enablement & Best Practices
• Train HPC teams and scientific users on Quandela's SDK, simulators, cloud platform, and hybrid programming models.
• Produce architecture guides, playbooks, and technical reference materials for customers and partners.
• Contribute to building technical blueprints and reusable architectures for repeatable deployments.
• 6. Cross-Functional Collaboration
• Work closely with Product and Engineering teams to feed customer needs into the roadmap.
• Partner with Sales to support technical qualification, RFP responses, and executive discussions.
• Contribute to standards, reference architectures, and interoperability initiatives with ecosystem partners.
