About The Role As a Senior Logic Design Engineer, you'll become a part of a cross-functional development team engineering experiences of tomorrow.

Our client is an innovative technology company developing advanced control and measurement systems for quantum computing. Its hardware and software platforms enable precise, real-time control of complex quantum systems, supporting the evolution of quantum computing from individual qubits to large-scale architectures.

In this role, you will contribute to the development of next-generation FPGA and ASIC-based control platforms. You will design and optimize high-performance digital logic with stringent latency and timing requirements, working closely with system architects, verification engineers, software developers, and hardware specialists in an international engineering environment.

Responsibilities

Design and implement complex, configurable, low-latency RTL modules using SystemVerilog

Develop digital logic for high-performance FPGA and ASIC applications, including signal processing, waveform generation, and real-time control

Participate in the complete RTL development lifecycle, from architecture and microarchitecture definition to implementation and verification

Optimize RTL designs for timing, latency, resource utilization,



and power efficiency

Perform logic synthesis, static timing analysis (STA), and optimization to meet design constraints

Collaborate with verification engineers to ensure functional correctness and comprehensive test coverage

Analyze system-level and software requirements and implement appropriate hardware-software interfaces

Integrate proprietary digital IP into complex FPGA/ASIC architectures

Participate in design reviews, debugging, and continuous improvement of engineering processes

Requirements

Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related technical discipline (or equivalent practical experience)

4+ years of professional experience in FPGA or ASIC digital logic design

Strong practical experience in RTL development using SystemVerilog (mandatory)

Solid understanding of digital logic design, computer architecture, and RTL microarchitecture

Experience with logic synthesis, static timing analysis (STA), and timing optimization

Practical experience with FPGA or ASIC design and implementation workflows

Understanding of clock-domain crossing (CDC), synchronous digital design, and hardware interfaces

Experience with simulation-based RTL verification and debugging

Strong analytical, problem-solving, and communication skills





English proficiency sufficient for effective collaboration within an international engineering team

Desirable

Experience with AMD/Xilinx FPGA platforms, particularly AMD Versal.

Experience with AMD Vivado and related FPGA implementation tools.

Familiarity with Synopsys VCS, Siemens Questa, or equivalent simulation tools.

Experience with digital signal processing (DSP), waveform generation, or high-speed data acquisition.

Experience developing deterministic, ultra-low-latency digital systems.

Familiarity with AXI, PCIe, DDR, or other high-performance hardware interfaces.

Experience with ASIC-oriented RTL development and reusable digital IP.

Knowledge of Python, Tcl, or other languages used for development automation.

Experience with hardware-software co-design and embedded systems.

Experience in quantum computing, telecommunications, measurement equipment, or other performance-critical digital systems.
