## Description

You'll work across the full stack - from performance-optimized algorithms to developer-facing documentation - helping partners, clients, and investors understand why computing with light is the future.
What You Will Do

 * Figure out how algorithms make a difference with photonics
 * Optimize algorithms and develop performance-critical code (Python, C/C++, Rust) to demonstrate the full potential of photonic hardware through compelling performance benchmarks
 * Collaborate with algorithms and software ecosystem teams to refine architectural designs and provide structured feedback from real-world applications
 * Work with external partners and clients on use cases and proof-of-concepts that demonstrate the value of photonic computing for AI and scientific workloads
 * Build developer-facing assets: tutorials, reference implementations, demos, benchmarks, Jupyter notebooks, and documentation that enable developers to write optimized code for photonic hardware
 * Deliver public presentations, workshops, and technical briefings on photonic computing applications
 * Manage stakeholder expectations and project timelines across client engagements and partner collaborations
 * Contribute to Q.ANT's Open Source initiatives and developer ecosystem
