FPGA Engineer – Quantum Computing (f/m/d)

Über diese Stelle

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

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
