About Us

QuantWare is the world's leading manufacturer of superconducting quantum hardware. As a high growth start-up with a global customer base, our mission is to accelerate the advent of the quantum computer. We push the boundaries of what's possible in our field. We work on making the world's largest quantum processors, as fast as possible.

At QuantWare, we're not just producing quantum hardware for the hyperscalers of tomorrow; we're working on technology that will change the world. To make that ambition a reality, we need exceptional people who drive real impact. That's where you come in.

As a Customer Success Engineer , you will support our customers to be successful with QuantWare's products; helping customers understand, evaluate, and integrate QuantWare's products into their systems. You will get to work with both technical and commercial experts and play a key role in driving the broad adoption of QuantWare's quantum hardware.

What you'll be doing:

In this role, you'll combine deep technical understanding with strong communication skills to enable the success of our customers. You will:

• Serve as the primary technical liaison between customers and the internal engineering, and product teams.

• Support customers throughout the full lifecycle - from onboarding and system setup to calibration, operation, and performance optimization of quantum processors.

• Translate customer requirements into actionable feedback for product and engineering teams to improve hardware, documentation and training materials.

• Develop and maintain technical training materials, best-practices guides to enable customers to effectively use the company's quantum technology.

• Troubleshoot hardware, and integration issues, coordinating with R&D to ensure rapid resolution and continuous improvement.

• Gather and communicate customer insights to influence roadmap and product development priorities.

• Represent the company at conferences, customer meetings, and partner collaborations.

Your profile

We're looking for someone who combines quantum know-how with a practical, customer-focused mindset, eager to deepen understanding of quantum technology and stay on top of developments in the field that combines:

• At minimum a MSc in Physics, Electrical Engineering, with a focus on experimentalquantum computing or cQED (strong preference for superconducting quantum computing).

• Solid understanding of quantum hardware (e.g., superconducting qubits, cryogenics, microwave engineering) with an experimental quantum background, very preferably superconducting.

• Excellent communication skills, able to explain complex concepts clearly to both technical and non-technical audiences.

• Experience in a customer-facing or technical support role is a plus.

• Comfortable working in a fast-paced, multidisciplinary environment.

• Eager to deepen technical understanding of quantum hardware.
