Company Overview
LIGENTEC is a young, dynamic, and rapidly growing company headquartered in Lausanne, Switzerland, near EPFL, close to the shores of Lake Geneva. We develop high-performance Photonic Integrated Circuits (PICs) for Quantum Technologies, LiDAR, Space, Biosensors, and more.
Position
Photonic Design & Optimisation Engineer
Responsibilities
Design, simulate, and optimize cutting‑edge passive and active photonic components (e.g., couplers, filters, modulators, photodiodes) for customer projects and strategic internal roadmaps, focusing on RF and CW domains.
Explore and implement advanced design methodologies, including inverse design and computational techniques, to push the limits of component performance.
Contribute to the hands‑on layout of photonic components and circuits, ensuring physical realization adheres to design intent, best practices, and manufacturing constraints.
Critically assess the performance of designed components and circuits by analyzing complex experimental data and iterating the design cycle.
Conduct technical feasibility studies for customer projects, defining required component performance and architectural approach.
Interface with Characterisation, Process, and Yield Engineering teams to gather requirements, capabilities, and support definition of test structures and test plans.
Provide concise and clear documentation and reporting on design methodology, component performance, and optimisation results.
Qualifications & Requirements
MSc or PhD in photonics, electrical engineering, or a related field.
Minimum of 3+ years of hands‑on experience in advanced integrated optics design and optimisation in an industrial or comparable environment.
Proficiency in designing passive photonic components and complex circuits.
Competence with layout tools (e.g., IPKISS) and best practices to effectively contribute to component layout.
Strong proficiency in Python programming for simulation, optimisation, and data analysis; familiarity with code versioning (e.g., Git) is a plus.
Expertise in analysing datasets from photonic components and circuits.
Familiarity with active components, heterogeneous integration, and advanced design techniques (inverse design, topology optimisation) is a strong plus.
Deep understanding of PIC manufacturing and test implications on design (design‑for‑testability and design‑for‑manufacturability).
Collaborative, solution‑oriented mindset and eagerness to learn and grow.
Working proficiency in English.
Benefits
A flexible and dynamic start‑up work environment.
Part of an international, diverse, customer‑focused and highly motivated team.
Personal responsibility in your role and opportunities for growth.
A passion for bringing PICs to everyday life.
