eleQtron develops full-stack quantum computers based on trapped-ion technology. The company combines laser-cooled trapped ions with microwave control and tailored magnetic fields to build next-generation computing machines capable of solving problems currently out of reach.
You will own the real-time firmware that transforms control electronics into a working quantum computer. Working on the next-generation system where control electronics are being integrated into a single, highly integrated chip, you will sit at the heart of the machine—between the hardware generating pulses and higher-level software describing experiments. Your role is critical: ensuring the right signal reaches the ions at the right nanosecond, reliably, run after run.
Key Responsibilities:
- Own the embedded firmware on the ARM-based control platform, from architecture through implementation to on-hardware debugging
- Develop and maintain the real-time software layer coordinating pulse sequencing, timing, and data flow across the highly integrated control chip
- Write and maintain low-level drivers and board support the hardware relies on
- Guarantee deterministic, low-latency behaviour under hard real-time constraints
- Lead firmware bring-up with electronics and physics teams, debugging at the boundary where software meets signal
- Define firmware architecture and engineering practices—build, test, and release processes—as the system matures
- Contribute to interfaces between the embedded layer and the rest of the stack, ensuring 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, with clear understanding of when each is appropriate
- Comfortable reading schematics and datasheets, debugging real hardware with oscilloscopes, logic analysers, and JTAG
- Strong grasp of real-time concepts: interrupts, DMA, timing, concurrency, and determinism
- Track record of bringing up firmware on new hardware, not only maintaining existing systems
- Ability to collaborate effectively with experimental physicists and engineers, turning imprecise physical requirements into robust firmware
- Strong adaptability and quick learning mindset
- Good proficiency in English (written and spoken)
Bonus Skills:
- 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
