Firmware Engineer
At planqc, we are building scalable quantum computers based on neutral atoms, one of the most promising platforms for achieving real-world quantum advantage. Keeping our quantum processors stable and reliable depends on precise, continuous control and monitoring of the physical conditions they operate in such as temperature and pressure and on rigorous testing of the electronics that make this possible.
As a Firmware Engineer, you will join our Electrical Engineering team to develop the digital control and monitoring systems that are critical components of our quantum computing platform. Your work will focus on designing and implementing MCU-based solutions that enable the precise control and supervision of environmental parameters. In addition, you will contribute to the development of our automatic electronic testing and verification procedures, test report generation, and documentation.
Your contributions will be critical in advancing system performance, stability, scalability, and verification, as well as in bringing planqc’s quantum hardware to market. This role is ideal for engineers who enjoy working at the intersection of hardware, firmware, and cutting-edge physics.
- Design and optimize low-speed control firmware (e.g. microcontrollers, Raspberry Pi) for planqc’s electronics hardware.
- Implement digital interfaces with sensors, low-speed ADCs, DACs, and other peripherals.
- Maintain and continuously improve planqc’s environmental monitoring infrastructure.
- Develop and implement automatic test and verification processes for electronic components.
- Degree in Physics or Electrical Engineering.
- Very good command of C/C++ in the context of microcontroller programming.
- Strong Python background.
- Proficient in programming 32-bit microcontrollers (e.g. STM32 or similar).
- Familiarity with Raspberry Pi, BeagleBone, or similar embedded platforms.
- Experience interfacing hardware components via protocols such as I2C, SPI, and Ethernet.
- Basic understanding of circuit diagrams.
- Ability to debug simple digital circuits.
- confidence using version control (git) tools.
- Experience working in a laboratory environment.
- Familiarity with Grafana or similar visualization and analytics tools.
- Experience with open-source databases (e.g. MySQL, InfluxDB, or similar).
- You enjoy working on problems at the hardware-firmware boundary.
- You are willing to take full ownership of your tasks.
- You are able to drive projects from concept to deployment.
- You are structured and detail-oriented.
- You are quality-conscious in everything you build.
We combine deep-tech research with an engineering mindset, turning scientific breakthroughs into scalable quantum systems.
Joining us means:
- Working on cutting-edge neutral atom quantum hardware
- Taking ownership of quantum systems from day one
- Collaborating with an exceptional, international team across disciplines
- Contributing to a fast-growing quantum startup at a pivotal stage
- Flexible working. Flexible hours and hybrid work where the role allows.
- Company pension. Betriebliche Altersvorsorge with an employer contribution.
- Health and fitness. EGYM Wellpass for gyms, pools and studios, plus regular Health Days.
- Job bike. Lease a bike through planqc.
- Learning and development. Trainings and conference participation, including international conferences. Plus regular internal learning sessions where colleagues share their knowledge.
- Relocation and visa support. Practical support for international hires and their move to Germany or Austria.
- Four locations. Headquarters in Garching, an office in central Munich, plus sites in Ulm and Innsbruck.
- Team culture. Regular team and company events throughout the year, from after work socials to our summer and Christmas parties.
