Senior Software Engineer - Photonic Ecosystem (f/m/d)

Own the photonic enablement of the open-source software ecosystem - drive integration of Q.ANT’s hardware capabilities into base libraries (OpenBLAS, Eigen, numpy) and AI frameworks (PyTorch, JAX, TensorFlow, llama.cpp, vllm)

Get code accepted into upstream repositories and package managers so that default installations support Q.ANT hardware out of the box - and maintain it long-term

Serve as Q.ANT’s focal point for open-source software projects - build trust, demonstrate reliability, and represent Q.ANT professionally in development communities such as the PyTorch community

Guide ecosystem partners of Q.ANT on design, development, upstreaming, and maintenance of their code and packages; deliver technical briefings and training to partners and internal teams

Enhance the common native photonic standard library, ensuring frictionless, vendor-agnostic use across the software ecosystem

Align closely with internal teams - algorithms, compiler, device control, infrastructure, system architecture - and bridge external community requirements back into Q.ANT’s development roadmap

Make impact at scale: Help solve one of computing’s biggest challenges - making growing demand in compute and sustainability go hand in hand

Work on the leading edge: Photonic AI acceleration technologies that will define the next decade of computing - already validated in production HPC environments

Own your work from day one: Shape design and code of software, client solutions, and public collaterals on your own, with direct impact on product success and the future of AI infrastructure

Fast-track your growth: Work on challenges with few industry precedents - every problem you solve becomes new institutional knowledge and potentially industry-defining IP

Be the multiplier: Your work enables entire developer communities and directly helps clients succeed with photonic computing

World-class team: Collaborate alongside a passionate, international, cross-functional team of experts in photonics, processor design, and AI software

Direct access to leadership: Work closely with the company’s founders, including CEO Dr. Michael Förtsch, and the Q.ANT senior leadership team

Collaborative culture: Innovative work environment that values technical excellence, open communication, and pragmatic problem-solving

Be part of history: Join at the inflection point where photonic computing transitions from research to mainstream - your contributions will shape this transformation
