Senior Design Engineer (ID: 2605)

LIGENTEC is a young, dynamic and strongly growing company, headquartered in Lausanne, Switzerland, near EPFL, close to the shore of Lake Geneva. We are developing Photonic Integrated Circuits (PICs) to world-leading performance with our customers for applications in Quantum Technologies, LiDAR, Space, Biosensors and more.

To support our growth, we are looking for a:

LIGENTEC is seeking a Senior Design Engineer to serve as a key technical expert within our engineering team. This role is central to the design and development of complex Photonic Integrated Circuits (PICs) for both customer projects and internal strategic growth.

• →Design & Layout Execution: Drive the design and layout of PICs, focusing on single-component optimization, circuit-level simulation, and achieving project objectives.
• →Modeling & Analysis: Conduct circuit simulations for PICs going into products, analyze large datasets, and develop and implement custom models to close the gap towards first-time right design.
• →Design Infrastructure: Develop and maintain LIGENTEC’s layout library to ensure adherence to best layout practices and design-for-manufacturability (DFM).
• →Design Flow Optimization and Efficiency: Proactively audit, analyze, and optimize the entire Design and Layout flow to identify critical bottlenecks, implementing strategic changes and automation to significantly reduce the design/layout cycle time across all team projects and ensure maximum engineering efficiency
• →Technical Planning: Responsible for project feasibility analysis and preparing clear, concise technical documentation and reporting.
• →Work closely within cross-functional teams (Process, Testing) to ensure successful PIC development
• →Provide technical guidance to junior engineers.

• MSc or PhD in Photonics or a related field.
• Minimum of 7+ years of hands-on, industrial experience in integrated optics design and layout.
• A solutions-oriented mindset, critical thinking abilities, and the capacity to thrive in a dynamic, shifting environment.

• Designing passive photonic components and circuits.
• Python programming and code versioning.
• Single components and large circuits layout (IPKISS tool knowledge is a plus).

• How PIC manufacturing affects design and layout (DFT/DFM).
• Active components design and heterogeneous integration.
• Developing custom analytic and semi-analytic models.
• Expertise with PIC packaging is a plus.
• Collaborative team player, independent self-starter, and excellent communicator (English proficiency required).
