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:
**Senior Design Engineer**
## Tasks
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.
**Key Responsibilities:**
* 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.
## Requirements
**Qualifications and Requirements:**
* 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.
**Expert proficiency in:**
* Designing passive photonic components and circuits.
* Python programming and code versioning.
* Single components and large circuits layout (IPKISS tool knowledge is a plus).
**Familiarity with:**
* 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).
## Benefits
* A flexible and dynamic start-up work environment.
* Be a member 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.
