Job Description

At Qblox, we are orchestrating the "brain" of the quantum computer. Our distributed control stacks allow for parallel qubit readout and nanosecond-level synchronization across massive architectures. Imagine the complexity of all-to-all connectivity for 1000 qubits, interacting with physical hardware via high-frequency analogue signals—that is the scale of the challenge our verification team faces. As we expand our R&D capabilities, we are looking for a Digital Verification Engineer to ensure our hardware is as reliable as the physics it controls. The Role You will be a key driver in our RTL verification strategy, developing robust, metric-driven testbenches at both the module and system levels. This is not a siloed role; you will act as a technical sparring partner for our Digital Design and Embedded Software teams, influencing architecture and processes by proposing improvements based on industry best practices. At Qblox, we foster a culture of ownership. You will have the opportunity to influence technical decisions at a high level and gain a deep understanding of the entire quantum control stack, learning from our in-house physics experts along the way. What You Will Do Own the Verification: Autonomously develop robust, metric-driven testbenches for complex FPGA/RTL modules and full systems. Bridge the Disciplines: Collaborate closely with Digital Design and Embedded Software engineers to analyze requirements and verify technical solutions. Interpret Complexity: Work with internal design specs and vendor documentation for FPGAs, third-party ASICs, and software. Drive Methodology: Proactively suggest and implement new tools, methodologies (like Cocotb), and advancements in the verification domain. Analyze & Evaluate: Understand and interpret VHDL code to ensure effective verification coverage while maintaining a collaborative loop with designers. Why Qblox? We offer a dynamic environment where engineering meets cutting-edge physics research. You’ll be part of a highly international team that values inclusive knowledge exchange, technical ownership, and a healthy work-life balance. Enough about us, what about you? To thrive in this environment, you likely possess a "first-principles" approach to problem-solving and a drive to see complex R&D projects through to completion. The Background: 4+ years of experience in RTL verification within an R&D environment. The Technical Core: Expertise in verification planning and implementing self-checking testbenches. You are fluent in SystemVerilog/UVM and have a strong grasp of Python (OOP). The Tools: Hands-on experience with high-end simulators (Cadence Xcelium, Synopsys VCS) and a solid understanding of VHDL. The Architectural Sense: Familiarity with processor and bus-system architectures (e.g., AMBA AXI, Avalon). The Essentials: Proficiency with Git for version control and a results-driven mindset with a high degree of accountability. The "Nice to Haves": Knowledge of Cocotb and PyUVM is a significant plus. Experience with CI/CD (GitLab), container technologies (Docker/Podman), C/C++, or lab-based product validation will help you hit the ground running.

Core Responsibilities

You will develop robust, metric-driven testbenches for complex FPGA/RTL modules and full systems while collaborating with design and software teams. Additionally, you will drive verification methodology improvements and ensure hardware reliability through effective coverage analysis.

Requirements

The role requires 4+ years of experience in RTL verification within an R&D environment. Candidates must be fluent in SystemVerilog/UVM, have a strong grasp of Python, and possess familiarity with processor and bus-system architectures.
