Job summary

PsiQuantum is seeking a digital hardware system architect to join our System-Architecture team in shaping the digital-logic systems that drive our photonic quantum computer. You will work in a multi-technology environment translating abstract requirements into concrete hardware, and implementing low-latency algorithms for the data-plane.

You will collaborate with physicists and digital designers to optimize designs for performance, latency, and footprint, and will write verification and

Qualifications

• Bachelor's or master's degree in Electrical or Computer Engineering or related discipline.
• 5+ years of relevant work in digital design.
• Knowledge of SystemVerilog (or VHDL) for design and simulation.
• Experience working with FPGAs (Xilinx preferred) and associated tooling.
• Strong critical thinking skills to devise creative and analytical approaches to solving novel, loosely-defined complex problems.
• Team player with an ability to work effectively across departments and time-zones.
• Excellent verbal and written communication skills, with the ability to engage a variety of audiences.
• Experienced Python programmer who strives to write clear code in the context of a small team of contributors.
• Pro‑active with the ability to work independently with limited direction, in a fast‑moving start‑up environment nice‑to‑have:
• Distributed system experience: involving event correlation from multiple sources, under real‑time constraints.
• Experience with High Level Synthesis tools (e.g. Xilinx Vitis).
• Experience with Python for verification (Cocotb).
• Knowledge of photonics and linear optics is a plus.

Responsibilities

• Gather and translate high-level abstract requirements into concrete hardware requirements.
• Devise and implement low-latency algorithms and methods to solve various time-critical tasks that take place in the data-plane of an optical quantum computer.
• Work with other digital-design experts to integrate algorithms into FPGAs.
• Collaborate closely with physicists and digital designers to arbitrate design choices and optimize designs to meet algorithmic performance while matching latency, throughput and footprint constraints.
• Write requirements and documentation.
• Implement cycle-accurate Python models to be integrated in discrete-time-event simulations.
• Implement SystemVerilog implementations matching Python models.
• Write behavioral tests for implementations in Python.
