Benefits

Indicative salary range:
- €53-58K gross-Intermediate profile (recent or near-completion PhD, or 2-3 years of PIC design experience with solid simulation autonomy and layout experience)
-€58-65Kgross-experienced profile (3-5+ years of PIC design experience, able to own larger design blocks and contribute to methodology and architectural decisions)

Perks: annualprofit-sharing- company savings plan - 100% health coverage (Alan) - transport reimbursement or mobility bonus -Swilemeal vouchers -Gymlibaccess.

What will you do?

Design and simulate photonic components
-Perform electromagnetic and thermal simulations (Lumericalrequired; Tidy3D or similar is a plus)
- Analyze trade-offs between loss, footprint, fabrication tolerance, and performance
- Design and optimize waveguides, interferometers, beam splitters, phase shifters, and reconfigurable elements
- Contribute to next-generation components, including high-speed and new-material integrations

Translate simulations into manufacturable layouts
- Generate mask layouts using GDS-based tools
- Prepare designs for tape-out with external foundries
- Ensure designsremaincompatible with real fabrication constraints

Collaborate with characterization
- Analyze measured data against simulations and identify performance gaps
- Refine models and layouts based on fabrication and experimental feedback
- Contribute to continuous performance improvements

Howyou'llgrow?

0/3 months Understand our simulation environment and reproduce existingcomponentdesigns.

3-6 months Lead a full simulation-to-layout cycle on a definedcomponent.

6-12 months Contribute to design improvements and take part in next-generationcomponentdevelopment,supporting the transition toward higher-speed reconfiguration regimes and tighter performance constraints.

Longer term Take ownership of architectural blocks or contribute to defining structured design methodologies as our PIC platform evolves toward larger and fault-tolerant systems.

Whatwe'relooking for:

Must-have:

- Master's or PhD in Photonics, Physics,ElectronicEngineering or related field
- Hands-on experience in PIC simulation (Lumericalstrongly preferred)
- Experience translating simulations into manufacturable layouts using GDS-based tools (GDSFactory, IPKISS, KLayout, or similar)
- Understanding of integrated photonics fundamentals (waveguide physics, interferometers, beam splitters and phase control mechanisms)
-Ability to reason at circuit level, beyond individual components
- Professional English

Important (can grow here):

- Experience closing the loop between simulation and experimental results
- Familiarity with fabrication constraints and design-for-manufacturing logic
- Python for automation,scriptingor data analysis
-Interest in scalable or quantum hardware architectures(quantum knowledge is a plus, not a prerequisite)

Bonus:

- Experience in industrial PIC platforms or foundry-driven environment
- Exposure to high-speed photonic components or cryogenic constraints
- Familiarity with inverse design and particleswarm optimization

We welcome strong PhD profiles as well as engineers with a few years of experience.
What matters most is simulation autonomy, strong physical intuition, and the ability to turn models into robust devices while thinking at system scale.
