eleQtron develops and operates full-stack quantum computers based on trapped-ion technology. Quantum computing is a new computing paradigm rapidly approaching commercial viability. Our unique approach combines laser-cooled trapped ions with microwave control and tailored magnetic fields. Our next-generation computing machines under development will be able to find solutions to problems that are out of reach today, thus enabling new innovative products and services for a brighter future.
We are looking for a Senior Embedded (ARM) Engineer (m/f/d) to join us in Hamburg or Siegen and own the real-time firmware that turns our control electronics into a working quantum computer. You will work on our next-generation system, where the control electronics are being integrated into a single, highly integrated chip. You sit at the heart of the machine, between the hardware that generates the pulses and the higher-level software that describes the experiments. Timing is not a detail here; it is the product. You are the person who makes sure the right signal reaches the ions at the right nanosecond, reliably, run after run.
Responsibilities:
Own the embedded firmware on our ARM-based control platform, from architecture through implementation to on-hardware debugging
Develop and maintain the real-time software layer that coordinates pulse sequencing, timing, and data flow across our highly integrated control chip
Write and maintain the low-level drivers and board support the hardware relies on
Guarantee deterministic, low-latency behaviour under hard real-time constraints
Lead firmware bring-up together with our electronics and physics teams, and debug at the boundary where software meets signal
Define the firmware architecture and engineering practices — build, test, and release processes for the embedded layer as the system matures
Contribute to the interfaces between the embedded layer and the rest of the stack, so experiments defined in software run correctly on the machine
Required Skills:
5+ years of professional embedded software development for real-time or timing-critical systems
Deep command of C (and ideally C++) on ARM platforms, working close to the hardware
Experience with bare-metal and/or RTOS environments, and a clear understanding of when each is appropriate
Comfortable reading schematics and datasheets, and debugging real hardware with oscilloscopes, logic analysers, and JTAG
Strong grasp of real-time concepts: interrupts, DMA, timing, concurrency, and determinism
A track record of bringing up firmware on new hardware, not only maintaining existing systems
Ability to collaborate effectively with experimental physicists and engineers, and to turn imprecise physical requirements into robust firmware
Strong adaptability and a quick learning mindset
Good proficiency in English (written and spoken)
Nice to have (Bonus)
Experience on highly integrated SoCs, particularly ARM+FPGA platforms such as Xilinx Zynq / RFSoC
Working alongside FPGA/digital-electronics engineers at the software–gateware boundary
Rust for embedded systems
Embedded Linux on ARM (Cortex-A), including driver and kernel-module work
Signal processing or control-loop implementation on embedded targets
Experience with high-speed data acquisition or precision timing systems
Familiarity with laboratory, scientific, or measurement instrumentation
Prior experience with quantum computing or other deep-tech domains
What you can expect from eleQtron:
Competitive salary: We value our team members and therefore provide remunerations that reflect this, additionally rewarding achievements
Flexible working hours: We offer personal freedom through a variety of flexible work schedules
Team spirit: In our international and diverse team, and with our regular team events, having fun at work is simply part of the culture
Further development: We want to grow together and so we offer our team members needs-based, individualized further training as well as plenty of room for personal development
Wellness Package: We offer health-promoting benefits such as fitness programs like UrbanSportsClub to support your well-being
Bike Leasing: Stay Mobile and Sustainable with Our Company Bike Leasing Program
Moving Benefits: A warm welcome! We are happy to support employees who move for us with a bonus
At the forefront: Work at the forefront of technology, where academic research meets commercial applications
Modern workplace: We have a high-quality infrastructure with laboratory space, offices and meeting rooms
