<p>In this role, you will be an integral part of the development process for IDQ's SNSPD platform, with applications across quantum computing, networking, and sensing. You will be at the intersection of quantum photonics, cryogenic systems engineering and embedded systems to create scalable, maintainable architectures for autonomous 24/7 detector operations.</p>
<p>You will take ownership of the end-to-end system architecture of the SNSPD platform, ensuring alignment with a shared long-term product vision while translating product requirements into clear system-level designs and specifications. This includes defining system structure, interfaces, and key architectural decisions, as well as driving critical trade-offs across performance, cost, scalability, and integration. You will also align engineering execution with the architectural vision, guiding system integration and resolving complex cross-domain design challenges.</p>
<p>In addition, you will play a key role in shaping the technology roadmap and driving the evolution of the platform, continuously evaluating and introducing new technologies where relevant to maintain innovation and competitiveness.</p>
<ul>
<li>Lead system architecture, design decisions, and cross-functional alignment to ensure a scalable and high-performing SNSPD platform</li>
<li>Drive technology roadmap, integration, and innovation by evaluating and implementing new technologies</li>
