Post-Silicon Validation Manager

Department: Cryo-CMOS

Location: Dublin

Employment Type: FullTime

We are seeking an experienced Silicon Validation Manager to join our silicon design team and lead validation activities for our Quantum SoC controller and integrated quantum solutions. This is a hands-on leadership role spanning FPGA-based pre-silicon verification, post-silicon validation and debug, and lab management, including validation at both room temperature and cryogenic temperatures.

In this position, you will play a key role in shaping Equal1’s validation strategy across multiple global sites, while mentoring a multidisciplinary team delivering next-generation quantum hardware.

Main Duties and Responsibilities

• Lead post-silicon validation and debug of QSoCs, including digital systems with embedded ARM cores, precision analog/mixed-signal blocks, and RF circuits for qubit control and measurement. This extends to device characterisation across samples, at room and at cryo temperatures.

• Collaborate with design, verification, architecture, firmware, and quantum engineering teams to rapidly isolate, root-cause, and resolve QSoC-level issues.

• Manage FPGA-based pre-silicon verification, including emulation of digital, analog, and RF paths, firmware test harnesses, and validation software. This includes RFSoC platforms for early system-level testing of complete multi-qubit quantum systems.

• Coordinate coherent multi-site lab operations and validation workflows, including procurement, calibration, and maintenance of cryogenic, RF, analog, and digital test infrastructure.

• Ensure sample board readiness and quality through bring-up, rework, revisions, PCB evaluation, packaging considerations, and controlled distribution.

• Own the automation and scripting frameworks (Python, C, Bash, or similar) to enable repeatable, accelerated, and scalable device debug, data capture, and regression testing.

• Provide technical leadership and mentorship for engineers and the quantum measurement team, and shape quantum validation strategy, methodologies, and best practices across global sites.

• Play a significant role in the architecture and design of next-generation QSoC devices, packaging, and quantum collateral.

Experience and Qualifications

Required

• Strong understanding of semiconductor device physics, including transistor operation, analog/mixed-signal behaviour, noise, parasitics, process variation, and their impact on system-level performance.

• Hands-on expertise with digital, analog, and RF debug techniques, including oscilloscopes, logic analyzers, VNAs, spectrum analyzers, SMUs, and high-speed digitizers.

• Experience validating devices at cryogenic temperatures, including qubit control/readout, RF chains, and coherent measurement methodologies (preferred).

• Strong FPGA-based pre-silicon verification experience, including RFSoC platforms.

• Familiarity with PCB and packaging tools such as Altium or Cadence Allegro, and understanding of board-level signal integrity, routing, and component placement considerations.

• Demonstrated ability in automation and scripting for repeatable, accelerated validation and debug workflows (Python, C, Bash, or similar).

• Proven leadership of engineering teams and multi-site technical programs, excellent mentorship, collaboration, and problem-solving skills.

Desired Experience

• Experience in quantum hardware or qubit control systems is highly desirable.
