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 ## How to apply Apply on the job page, https://germanydevjobs.com/jobs/eleqtron-senior-embedded-arm-engineer-quantum-computing-m-w-d-7nn79q8: its Apply button opens the employer's own application page. ## More jobs from eleQtron - [QPU Integration Engineer (Assembly & Characterization focused) (f/m/d)](https://germanydevjobs.com/jobs/eleqtron-qpu-integration-engineer-assembly-characterization-focused-f-0xgo9sw): eleQtron, Hamburg, Germany.
