Senior Sales Engineer - Quantum & HPC Infrastructure

Quandelais 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,Quandelais at the forefront of enablinghybrid quantum-classical architecturesacross Europe’s supercomputing ecosystem.

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

You willdrive the growth ofQuandela’sOffers 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 willidentifyand close opportunities, manage key accounts, and contribute to the overall go-to-market strategy forcutting-edgequantum solutions, this is ahunter role:you open doors, build strategic pipelines from scratch, and close landmark deals.

Your Mission Win new HPC customers across Europe.

PositionMosaiQas a strategic infrastructurecomponentin national and European roadmaps.

Capture high-value public and research-driven contracts.

EstablishQuandelaas a key quantum partner for leading supercomputing centers.

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

What You Will Do StrongMarket Expansion Identifyand penetrate new HPC accounts across Europe (national centers,EuroHPCsites, 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 fromcoldapproach tocontractsignature.

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

RepresentQuandelaat major industry events (ISC, SC,EuroHPCSummit).

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, andexecution-driven.

Experience 7+ years in B2B deep-tech sales (HPC, advanced infrastructure, AIcompute, 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.

Existingnetworkwithin 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
