(Senior) Quantum Software Engineer - Control System

At planqc, we are building scalable quantum computers based on neutral atoms. Operating these systems requires sophisticated software that connects experimental hardware, distributed control infrastructure, and higher-level quantum computing applications.

As a(Senior) Quantum Software Engineer – Control Systems, you will contribute to developing the software that operates and orchestrates planqc’s quantum computing systems. Your mission is to design and build robust control, monitoring, and analysis software that enables reliable operation of complex experimental hardware.

Working at the intersection ofsoftware engineering and quantum hardware, you will help shape the architecture of our control platform, integrating distributed services, APIs, and system components into a cohesive framework. Your work will directly support the operation and scalability of our quantum computing systems, ensuring that our hardware can be controlled, monitored, and deployed reliably across multiple systems.

This role is ideal for engineers who enjoy working ondistributed systems, control software, and complex technical environments, and who are motivated by contributing to the software infrastructure behind next-generation quantum technologies.

• Experience designing and maintainingRESTful or gRPC APIs.
• Familiarity withautomated testing frameworks (e.g., pytest).
• Experience working withGit and CI/CD pipelines.
• Ability to produceclear technical documentation and user guides.
• Master’s or PhD inComputer Science, Engineering, Physics, or a related technical field.
• Strong collaboration skills and the ability to work closely withexperimental physicists and engineers.
• Fluent inEnglish.

• Experience working inoptics or quantum physics laboratories, including software control of experimental setups (e.g., lasers, vacuum systems, atom or ion experiments).
• Experience withmessage brokers or asynchronous communication systems such as ZeroMQ, RabbitMQ, or Kafka.
• Familiarity withobservability and monitoring tools such as Prometheus, Grafana, or Jaeger.
• Experience withcontainer orchestration tools such as Docker Compose or Kubernetes.
• Experience withhardware-in-the-loop testing and integration with laboratory or industrial hardware.
• Contributions toopen-source projects or personal technical software projects.
• Experience working inagile or Scrum-based development environments.

• You are acollaborative engineer who enjoys working closely with interdisciplinary teams.
• You takeownership of complex technical challenges and approach them with curiosity and persistence.
• You are comfortable working at theinterface between software and experimental hardware.
• You are motivated to learn aboutquantum technologies and advanced experimental systems.
• You approach problems withpragmatism and strong engineering discipline, even in fast-moving R&D environments.
• You communicate clearly and valueknowledge sharing and constructive feedback within a team.

At planqc, we are building scalable quantum computers based on neutral atoms, one of the most promising approaches to realizing practical quantum advantage. Achieving this requires a team that combines deep expertise inquantum physics, engineering, software development, and business operations, working closely together to solve some of the most challenging problems in modern computing.

Joining planqc means becoming part of ahighly collaborative and interdisciplinary team where researchers and engineers work side by side to turn cutting-edge ideas into real technology. You will have the opportunity to takereal ownership of your work, contribute to critical systems, and see your solutions directly impact the development of next-generation quantum computers.

We aim to create an environment where people cangrow, stay curious, and do their best work. This includes supporting professional development throughtrainings, conferences, and learning opportunities, offeringhealth and wellbeing benefits, and providing the flexibility needed to balance focused work with personal life. As a growing deep-tech company, we also offer the chance totake on responsibility early and help shape both our technology and our culture.

We believe that building breakthrough technology requirescuriosity, openness, and strong collaboration and we are looking for people who are excited to grow with us while shaping the future of computing.

If you’re excited about buildingsoftware systems that operate cutting-edge quantum hardware, we’d love to hear from you.
