Job summary

QuantWare in Delft seeks an R&D Software Engineer to elevate production-grade software for measurement and data practices in VIO-related R&D. You will standardize experimental workflows, link data across devices, and collaborate across R&D, Product, and Operations to scale software and data capabilities.

You will develop robust Python code, manage measurement data, and drive improvements from prototype to production, enabling faster analysis and root-cause investigations in a multidisciplinary

Qualifications

• MSc in Computer Science, Electrical/Computer Engineering, or similar.
• 3+ years of industry experience (must).
• Experience building software that interacts with hardware (manufacturing, test & measurement, lab or factory automation, or control systems).
• Hands-on experience in control of test and measurement equipment is a plus; quantum device foundry/test facility is a strong plus.
• Strong Python with a track record of improving and maintaining code for data acquisition, automation, or scientific pipelines.
• Experience with databases and cloud computing suites like GCP and AWS for technical/experimental data.
• Good practices: OO design, Git, code review, testing frameworks.
• Strong drive to eliminate manual measurement and analysis overhead.
• Comfortable in a multidisciplinary scale-up, aligning with Ops and Product teams.

Responsibilities

• Data management: store and link R&D measurement data and metadata for cross-device comparisons.
• Turn measurement prototypes into robust, tested, maintainable code for VIO devices and PCM test vehicles.
• Refactor and maintain modular Python code with automated tests, CI/CD, and documentation.
• Collaborate with experimental physicists, RF test engineers, and electrical engineers to improve measurement code.
• Own R&D software functionality through validation, review, and integration.

Job description

R&D - Software Engineer

Quantware · Delft

Abroad Delft Full Time

About Us QuantWare is building the world’s most powerful quantum processors to solve humanity's greatest challenges. We do this with our unique VIO™ technology, the only QPU architecture that breaks the hardware barriers that have held quantum computing back, unlocking the path to MegaQubit quantum processors. With VIO, we are paving the way for the hyper‑scale quantum computers that will change the world. And delivering on that vision demands people who don't shy away from tackling the hardest challenges of our time. That's where you come in!

We are looking for an R&D Software Engineer to bring production‑grade software and data practices into our R&D measurement work. As we scale up VIO, our measurement data, metadata, and codebase are growing fast. You will take our existing measurement software and data practices to the next level, making them robust and maintainable, and building on how we organize data so it supports analysis, yield, and root cause investigations at scale. As channel counts grow, PCMs and test vehicles multiply, and test setups become more varied, you will standardize our experimental workflows so measurement throughput never becomes the bottleneck. You will also be the link between R&D, the software team in Product, and the data team in Operations, so our efforts stay aligned.

What you’ll be doing

• Data management: Develop and maintain how R&D measurement data and metadata are stored, linking each device to its related tests, components, and setup history, so cross‑device comparisons and yield questions become a quick query.
• Measurement software: Turn measurement prototypes from experimental physicists and RF test engineers into robust, tested, maintainable code, and maintain the R&D measurement codebase for VIO devices, their components, and PCM test vehicles.
• Code architecture & quality: Review, refactor, and maintain modular Python code following modern software practices (automated testing with PyTest, CI/CD, documentation, version control).
• Collaboration: Work day‑to‑day with experimental physicists, RF test engineers and electrical engineers to improve their measurement code, and connect R&D with the software team in Product to bring in best practices.
• Ownership: Own R&D software functionality through validation, review, and integration.

Your Profile

• MSc in Computer Science, Electrical/Computer Engineering, or similar, plus 3+ years of industry experience (must).
• Experience building software that interacts with hardware, such as in the context of manufacturing companies, test and measurement systems, lab or factory automation, or control systems (must).
• Hands‑on experience in control of test and measurement equipment is a plus, and experience in a quantum device foundry or test facility is a strong plus.
• Strong Python, with a track record of improving and maintaining code for data acquisition, automation, or scientific pipelines.
• Experience working with databases and cloud computing suites like GCP and AWS for technical or experimental data.
• Working knowledge of best practices, including object‑oriented design, Git, code review, and testing frameworks.
• Strong drive to eliminate manual measurement and analysis overhead.
• Comfortable in a multidisciplinary scale‑up, translating between experimental hardware teams and production software, and aligning with other teams working on data and software (Ops, Product).

Don't tick every box? Research shows women often self‑select out if they don't meet every requirement. Here's our take: nobody ticks every box. This is a description of our ideal candidate, not a filter. If most resonates and you're keen to learn the gaps, apply. We hire for trajectory, not perfection.

What We Offer

• Competitive salary - A salary that reflects the impact and importance of the role (and of course 8% holiday allowance)
• Pension that's built to last - A generous and future‑proof pension plan that includes partner and dependent coverage.
• Flexibility built on trust - We focus on outcomes. Work flexibly, in a hybrid setup, with an open vacation policy that lets you manage your time.
• Personal growth - We invest in your L&D, with a budget available to each team member, dependent on their individual ambitions, development needs, and performance.
• A connected team - We make space to celebrate wins together, with team events, offsites, and spontaneous moments that bring us closer.

Diversity & Inclusion at QuantWare We're an ambitious company, not only for our goals but also to become an even more diverse and inclusive team. We know great candidates don't always follow a straight path, and we value diverse experience, perspectives, and ways of thinking. We know this helps us make better decisions, drives more innovation, and strengthens ou
