Photonics Design Engineer - PIC & Tape-Out

• Own and drive end-to-end tape-outs: lead circuit coordination, layout integration, DRC sign-off, documentation, and release readiness across multiple concurrent projects
• Act as the primary interface to foundries and external fabrication partners - aligning designs to process constraints, resolving design rule conflicts, and ensuring correct execution
• Contribute to PDK development and validation, and continuously improve the design workflow through automation, layout reuse, and review practice improvements
• Mentor junior engineers on photonic layout, verification, and tape-out best practices; spread a culture of rigour and ownership across the PIC team
• Feed design insights into Q.ANT’s photonic technology roadmap, proposing new components and optimisation strategies, * Make impact at scale: your design and tape-out work directly determines which photonic technologies reach production - high stakes, high impact from day one
• Work on the leading edge: photonic integrated circuit technologies that are shaping the next decade of computing
• Own your work from day one: shape tape-out strategy, PDK direction, and design workflow improvements with direct impact on product success
• Fast-track your growth: work on challenges with few industry precedents - every tape-out you drive becomes new institutional knowledge and potentially industry-defining IP
• World-class team: collaborate alongside a passionate, international, cross-functional team of experts in photonics, electronics, packaging, and fabrication
• 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

We are looking for a hands-on senior engineer who gets energized by owning complex tape-outs end to end, driving design quality and workflow rigour across a world-class PIC team, and directly shaping next-generation photonic technology. Ready to push the boundaries of what photonic integrated circuits can do?

We are looking forward to receiving your application!
