Senior Sales Engineer - Quantum & HPC Infrastructure

Quandela is a leading European quantum technology company pioneering the development and commercialization of photonic quantum computers. Our flagship quantum processing unit (QPU), MosaiQ, delivers scalable, reliable quantum computation for HPC centers, cloud providers, enterprises, and academic research institutions. As we expand our footprint across global markets, we are building a world-class sales team to support our growth. 

As quantum computing moves from experimentation to infrastructure deployment, Quandela is at the forefront of enabling hybrid quantum-classical architectures across Europe’s supercomputing ecosystem. 

To support our rapid growth, we are expanding our commercial team and seeking a Sales Engineer specialized in Quantum & HPC infrastructure. 

You will drive the growth of Quandela’s Offers sales across high-performance computing (HPC) centers, cloud infrastructure providers, enterprise clients, and research institutions. This is a strategic, consultative sales role focused on selling next-generation quantum computing hardware and associated services. 

As you will identify and close opportunities, manage key accounts, and contribute to the overall go-to-market strategy for cutting-edge quantum solutions, this is a hunter role: you open doors, build strategic pipelines from scratch, and close landmark deals. 

Your Mission 

• Win new HPC customers across Europe. 

• Position MosaiQ as a strategic infrastructure component in national and European roadmaps. 

• Capture high-value public and research-driven contracts. 

• Establish Quandela as a key quantum partner for leading supercomputing centers. 

You will operate at the crossroads of quantum computing, HPC, public funding ecosystems, and deep-tech infrastructure. 

What You Will Do 

Strong Market Expansion 

• Identify and penetrate new HPC accounts across Europe (national centers, EuroHPC sites, research supercomputers). 

• Proactively originate opportunities — not just respond to inbound demand. 

• Engage early in infrastructure planning cycles to influence future procurement decisions. 

• Build a qualified pipeline of strategic opportunities with multi-year revenue potential. 

 Complex Deal Leadership 

• Own the full sales cycle from cold approach to contract signature. 

• Lead high-value RFP responses and competitive tenders. 

• Navigate multi-stakeholder governance structures (technical committees, procurement boards, ministries). 

• Close long-cycle, infrastructure-scale deals (9–24 months). 

This is not transactional selling — it is strategic infrastructure selling. 

Hybrid Quantum-HPC Evangelism 

• Evangelize the integration of photonic QPUs within hybrid HPC environments. 

• Drive executive-level conversations around: 

• Quantum acceleration 

• National sovereignty in advanced computing 

• Post-exascale strategies 

• Translate deep technical value into infrastructure-level business impact. 

Strategic Relationship Building 

• Develop trusted relationships with: 

• HPC center directors 

• CTOs and infrastructure leads 

• Scientific computing heads 

• Government stakeholders 

• Represent Quandela at major industry events (ISC, SC, EuroHPC Summit). 

• Build ecosystem leverage with integrators and research consortia. 

What We Are Looking For 

Hunter Mindset 

• You thrive on opening new accounts and breaking into strategic institutions. 

• You are comfortable operating without an existing installed base. 

• You combine patience (long cycles) with relentless pipeline creation. 

• You are competitive, ambitious, and execution-driven. 

Experience 

• 7+ years in B2B deep-tech sales (HPC, advanced infrastructure, AI compute, scientific systems, or quantum technologies). 

• Proven success closing complex, high-value deals in public or research-driven ecosystems. 

• Strong experience with European public procurement and large infrastructure tenders. 

• Existing network within European HPC or advanced computing environments is a major plus. 

Technical Fluency 

You can confidently discuss: 

• HPC architectures (clusters, accelerators, interconnects, cooling, integration) 

• Data center constraints and infrastructure planning 

• Quantum computing fundamentals 

• Hybrid quantum-classical workflows 

You do not need to be a physicist — but you must command technical credibility. 

Soft Skills 

• Executive presence and strategic storytelling ability 

• Excellent negotiation skills 

• Ability to influence without authority 

• High resilience and long-term drive 

Why This Role Is Unique 

• You will sell frontier infrastructure technology — not incremental upgrades. 

• You will influence national supercomputing strategies. 

• You will help define how quantum integrates into Europe’s HPC backbone. 

• You will join a scale-up where your impact is visible and measurable. 

Why Join Quandela 

• Contribute to the deployment of photonic quantum computers within Europe’s leading HPC infrastructures. 

• Shape the integration of quantum acceleration into next-generation supercomputing architectures. 

• Join one of Europe’s fastest-growing quantum companies. 

• Work with a passionate, multidisciplinary team bridging quantum science and infrastructure engineering. 

• Competitive compensation with performance-based incentives.
