Senior Photonics Packaging Engineer RF (f/m/d)

The future of AI computing is light, not electrons. Q.ANT 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 Senior Photonics Packaging Engineer (f/m/d) , you will lead the specification, development, and verification of high-density photonic packaging solutions that integrate photonic integrated circuits (PICs), light sources, photodetectors, and analog circuitry into production-ready modules. You'll be the technical authority ensuring that supplier-delivered modules meet stringent optical, electrical, thermal, and mechanical requirements through precise definition of technical requirements, contractual agreements, and supplier project management.

What You Will Do:

• Lead cross-functional coordination across R&D, system engineering, manufacturing, and test teams to align packaging solutions with product architecture
• Act as primary interface for suppliers, managing technical goals, schedules, deliverables, contracts, and negotiations
• Define complete packaging requirements including optical coupling techniques, thermal management, RF signal integrity, and hermetic sealing methods
• Plan and oversee multi-party R&D projects , tracking milestones, budgets, and risks
• Ensure supplier quality ratings maintain ≥95% on-time delivery with zero critical defects and packaging costs within ±5% of targets

What You Bring

• 5+ years of experience in hybrid packaging, photonics assembly , or optoelectronic integration
• Hands-on experience with PICs , laser sources , photodetectors , analog electronics , and mixed-signal integration
• Deep expertise in optical coupling techniques , thermal management  for high-power photonic devices, RF module design and signal integrity , as well as packaging materials
• Proven track record managing supplier-led R&D projects from requirements through integration
• Strong leadership, negotiation, and systems thinking skills
• Master's or PhD in Photonics, Optoelectronics, Electrical Engineering, Physics, or a related field
• Fluent in English ; German beneficial

What We Offer

• 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: Broad autonomy and decision authority 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
• World-class team: Collaborate alongside a passionate, international, cross-functional team of experts in photonics, processor design, and AI systems
• Direct access to leadership: Work closely with the company's founders, including CEO Dr. Michael Förtsch, and advisory board members who shaped the semiconductor industry (ARM, Intel, Infineon)
• 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

We're looking for a technical leader who gets energized by developing novel photonic packaging solutions, managing supplier partnerships, and driving innovations that enable production systems to transform AI computing already today.
