Back to Careers
We are seeking a Quantum Engineering Intern to help prototype our quantum wiring product. The role involves contributing to the first versions of our simulation and measurement software, assisting in the installation and configuration of a cryogenic quantum measurement setup, and carrying out the initial thermal and quantum characterisations of our superconducting wiring prototypes. This internship is hands-on and experimental: you will work directly with hardware, instrumentation, and data to help us validate and iterate on core technology blocks.
About Isentroniq
At Isentroniq, we are building the future of computing, not in theory, but in hardware. We enable quantum computing at scale by developing superconducting circuits solutions to increase the qubit count by more than a 100x at fixed cost and size of infrastructure.
We share knowledge openly, challenge ideas constructively, and stay focused on what matters. Our values - gritty ambition with humility, radical candor, methodical audacity and sense of belonging - are at the core of how we work and grow.
If you’re passionate about transformative innovation, and ready to build what quantum needs to go further, join us and let’s shape the future together.
Key Responsibilities
Build a quantum wiring simulation software demonstrator. Python programming of a set of classes to represent cryogenic quantum wiring networks and evaluate their systems performance.
Assist in building a quantum measurement setup. Install and test a dilution refrigerator (10mK cryostat machine) and equip it with the necessary components and instruments to perform first cryogenic thermal characterizations and quantum measurements.
Set up quantum measurement frameworks. Run and program the first set of quantum characterization measurements of Isentroniq in the newly installed cryostat.
Who you are
We’re looking for a talented and passionate student, eager to learn and do hands-on experimental work and programming for quantum systems. You have an engineering mindset and love seeing ideas turn into working demos and products rapidly.
Key Qualifications
A Masters in quantum physics, with knowledge in quantum computing.
Python coding skills to build a new wiring simulation class.
Strong background in linear algebra. It is the heart of Quantum physics and microwave engineering. Two essential bits to build a quantum wiring simulator.
Communication proficiency in English. Your supervisor will be a world class quantum engineer but won’t speak French.
Personal Attributes
You are autonomous, ambitious, organized, and enjoy driving a project.
You are a builder. You are hands-on, enjoy discomfort and are not afraid to do make things from scratch: complete setups, scripts, purchases, processes, etc.
You value transparency and open communication, fostering trust and collaboration. You enjoy having your ideas and suggestions be boldly challenged and you feel free to speak about achievements and mistakes.
You are eager to learn and grow. You recognize the strength of teamwork. You feel challenged by competing alternative approaches, instead of looking down on them.
You thrive in an environment of high expectations, pushing boundaries to achieve breakthroughs.
What We Offer
A unique opportunity to participate to the origin of a cutting-edge start-up.
Work with and learn from world-class talents
A collaborative, mission-driven culture with a focus on personal and professional growth.
