Photonic Design and Optimisation Engineer
Join us at LIGENTEC in Lausanne, Switzerland to apply for the Photonic Design and Optimisation Engineer role. LIGENTEC is a young, dynamic, and rapidly growing company headquartered near EPFL, close to the shore of Lake Geneva, developing Photonic Integrated Circuits (PICs) for Quantum Technologies, LiDAR, Space, Biosensors, and more.
Location: Vufflens‑la‑Ville, Vaud, Switzerland.
To support our growth, we are looking for a skilled engineer who is passionate about advanced design techniques, component optimization, and translating performance requirements into novel photonic structures.
Role and Responsibilities
* Design, simulate, and optimize cutting‑edge passive and active photonic components (e.g., couplers, filters, modulators, photodiodes) for customer projects and internal roadmaps, focusing on RF and CW domains.
* Explore and implement advanced design methodologies, including inverse design and computational techniques, to push component performance limits.
* Contribute to the hands‑on layout of photonic components and circuits, ensuring the 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 feeding insights back into the design cycle.
* Support technical feasibility studies for customer projects, defining necessary component performance and architectural approaches.
* Interface with Characterization, Process, and Yield Engineering teams to gather requirements, assess capabilities, and support test structure and test plan definition.
* Provide concise and clear documentation and reporting on design methodology, component performance, and optimization results.
Qualifications and 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 optimization in a top environment, preferably industrial.
* Proficiency in designing passive photonic components and complex circuits.
* Competence with layout tools (e.g., IPKISS) and best practices.
* Strong proficiency in Python programming for simulation, optimization, and data analysis; familiarity with Git is a plus.
* Expertise in dataset analysis from photonic components and circuits.
* Familiarity with active components, heterogeneous integration, and advanced design techniques (inverse design, topology optimization) 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, eager 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 job and the chance to grow with us.
* Our passion to bring PICs to everyday life.
We look forward to receiving your full application, including 1) your CV, 2) a statement of interest (relating the position to your skills), and 3) grade or work certificates. Incomplete applications may not be considered.
