Job Summary

Your mission
The future of AI computing builds on light. is building photonic processing systems that compute with light - delivering a scalable energy-efficient alternative to transistor-based architectures for next-generation AI and HPC applications.

As Lead Software Engineer - Photonic Applications (f/m/d) youll bridge cutting-edge photonic hardware and real-world applications. Your work creates the evidence that photonic computing works: compelling demos developer enablement and direct partner collaboration that turn hardware capabilities into tangible success stories.

Youll 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 Open Source initiatives and developer ecosystem
Your profile
  • 5 years in software engineering across the stack with strong proficiency in Python and C/C or Rust for performance-critical components
  • 5 years working in the context of external partners clients or developer communities
  • Deep expertise in AI algorithms and scientific computing (PyTorch JAX TensorFlow) with understanding of hardware acceleration architectures and performance optimization
  • Experience developing demos/PoCs for novel hardware platforms and creating technical enablement content for developers is a plus
  • Familiarity with Open Source development workflows and tooling (GitHub CI/CD pipelines test frameworks Jupyter notebooks package distribution)
  • Bachelors or Masters degree in Computer Science Computer Engineering Physics Mathematics or related technical field
  • Fluent in English; German is a plus
Why us
  • Make impact at scale: Help solve one of computings 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 companys founders including CEO Dr. Michael Förtsch and the 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

Were looking for a technical problem-solver who gets energized by turning cutting-edge research into production-ready applications working directly with partners to solve real challenges and enabling developers to unlock the full potential of photonic computing.


Ready to show the world that photonic computing works We are looking forward to receiving your application!
