At planqc, we are building scalable quantum computers based on neutral atoms and developing the software stack that enables their operation.
As a Quantum Software Engineer Intern, you will contribute full time to the operating system that powers our quantum computers. Working within the Control Software team, you will help design, implement, and integrate distributed control, monitoring, and analysis software that runs across multiple quantum systems.
You will work on both pure software challenges and interfaces close to hardware, contributing to robust, scalable, and maintainable systems. Your work will directly impact how our quantum computers are controlled, monitored, and operated.
This role is ideal for students or early-career engineers who want to gain hands-on experience in building complex software systems in a cutting-edge deep-tech environment.

If you’re excited about building software systems that bring quantum computing closer to real-world applications, we’d love to hear from you.
planqc builds neutral-atom quantum computers based on arrays of optically trapped atoms controlled with high-precision laser systems. Our platform combines technologies from optical lattice clocks, quantum gas microscopes and fast Rydberg gates into a scalable computing architecture.
Founded in 2022 as a spin-off from MPQ and LMU Munich, we translate more than a decade of AMO research into deployable quantum systems. Our work spans vacuum and laser hardware, control electronics, firmware, system software and algorithm integration. We focus on turning complex experimental setups into stable, reproducible systems that operate in real computing environments.
Behind this technology is a team that pushes technical boundaries, values open exchange and shared ownership. Physicists, engineers, software developers and business specialists work closely together, often across disciplinary limits. We believe progress comes from combining deep expertise with practical engineering and from giving people the responsibility and trust to shape their domain.
As we grow across our locations in Garching, Ulm and Innsbruck, we continue to build an environment we continue to build a company where people take ownership, learn from each other, and directly shape the systems we bring into operation.
