Job description
Diraq is redefining scalable quantum computing by enabling billions of qubits on a single chip—far beyond the hundreds available today—to unlock practical, commercial quantum applications. We are building a full-stack quantum computing company, delivering quantum hardware and software as a cloud-accessible service.
Our proprietary technology, backed by over 20 years of research and more than $150 million in funding across 11 patent families, leverages existing silicon CMOS manufacturing and foundries to accelerate development and reduce costs—paving a faster, more efficient path to market.
We are a team of world-leading scientists, engineers, and business professionals. With a strong IP portfolio and partnerships with global technical and commercial leaders, we are shaping the quantum ecosystem of the future and driving meaningful impact across the entire industry.
As part of our global growth, Diraq is expanding into the United States, with initial operations in Silicon Valley and plans for additional strategic locations. This expansion enhances our access to top-tier talent and deepens collaboration with leading research institutions, government agencies, and commercial partners.
We are looking for a talented and highly motivated Electromagnetics/Microwave Simulation Engineer to join our growing team. You will be instrumental in supporting the delivery of our company’s ambitious technical roadmap. You will model and optimize electromagnetic performance for quantum processors operating at cryogenic temperatures, ensuring high-fidelity qubit control and scalability. The ideal candidate will have a strong background in physics, electrical engineering, or a related field, with experience in modelling, simulation, designing, and optimising electromagnetic performance of microelectronic devices. Your work will directly contribute to improving the quality and scalability of the qubit operations in our quantum processors.
Job requirements
Bachelor’s degree in electrical engineering, Physics, or a related field.
Minimum 3 years of experience in electromagnetics/microwave simulations.
Advanced understanding of electromagnetism and microwave engineering.
Familiarity with chip-package-board co-design and RF component integration.
Expertise in finite-element electromagnetics simulation tools such as HFSS or CST.
Proven ability to work in a team, collaborate across disciplines and build effective relationships.
Strong interpersonal skills with demonstrated ability to communicate with a diverse range of stakeholders, including students.
Proactive and keen learner.
Bonus if you have:
Comprehensive knowledge of semiconductors and CMOS technology.
Experience with COMSOL, ADS, or custom simulation scripting.
Experience with PCB design.
Experience with low-temperature and cryogenic models.
Strong understanding of micro/nano-magnets and ferromagnetism.
Understanding of, or experience working on, the Meissner effect and superconductivity.
Knowledge of quantum mechanics, quantum computing and/or gate-defined quantum dots
Job responsibilities
Design and develop realistic models of the entire quantum processors to carry out electromagnetics/microwave simulations.
Understand the quantum device requirements and convert them into measurable metrics for the simulations
Investigate the limitations of a given quantum processor system design from the electromagnetics perspective, upgrade the existing designs or devise new ones based on quantum device requirements.
Contribute to devising experiments to validate the simulated metrics.
Collaborate with cross-functional teams to make sure a design not only meets electromagnetic requirements, but also any thermal, microelectronic or manufacturability related requirements.
Develop simulation workflows that integrate with thermal and mechanical models for cryogenic environments.
Troubleshoot and resolve technical issues related to electromagnetic simulation software when needed.
Document concise and complete reports of key findings.
Contribute to a positive team culture and foster a collaborative working environment.
