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 an FPGA Engineer (m/f/d) to join our team in Hamburg. In this role, you will design, develop, and optimize FPGA-based systems that form the foundation of our quantum control stack, enabling high-performance signal generation and real-time control of our trapped-ion quantum computers.
Responsibilities:
You will join our Quantum Firmware Team as an FPGA engineer, owning the design and delivery of FPGA-based systems at the core of our quantum control stack. Working closely with hardware engineers and experimental physicists, you will develop high-performance microwave signal generation pipelines and real-time feedback control, directly shaping how our quantum computers operate at the lowest level. This role sits within a software engineering culture: we care about clean, well-tested, production-grade code, version-controlled workflows, and agile ways of working.
Design, implement, validate, and optimize FPGA systems in SystemVerilog, Verilog, or VHDL
Develop and maintain test benches and automation frameworks using Python (e.g. cocotb); validate FPGA integration on target hardware
Write production-grade, well-tested code and contribute to a culture of quality across the firmware stack
Conduct formal verification, including timing analysis, code coverage, and compliance with coding standards
Define verification strategies and test plans in close collaboration with the team
Develop and program test hardware to support automated execution of hardware test cases
Participate actively in agile ceremonies — sprint planning, reviews, and retrospectives
Required Skills:
3+ years of hands-on FPGA development experience
Bachelor's or master's degree in Electronics Engineering or a related field
Solid RTL coding skills in SystemVerilog, Verilog, or VHDL, including functional verification
Experience writing and maintaining automated tests for production code
Comfort working across disciplines alongside physicists, hardware engineers, and software teams
Strong learning agility and the ability to navigate an evolving technical environment
Professional proficiency in English (written and spoken)
We value:
Experience with RF signal generation and processing
Familiarity with CI/CD pipelines and automated build/test infrastructure
Experience controlling high-bandwidth (>1 GSPS) ADCs/DACs
Familiarity with Xilinx SoC devices and related toolchains (Vivado, Vitis/SDK)
Proficiency with Git and version-controlled development workflows
Experience working in agile teams (Scrum or Kanban)
Exposure to quantum computing systems or research environments
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
