Switzerland

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 Photonic Design Engineer**  
_(ID 2512)_

## Tasks

We are seeking a highly skilled and experienced Senior Design Engineer to join LIGENTEC’s engineering team. The ideal candidate will have a proven track record in designing and developing complex photonic integrated circuits (PICs). This role involves leading design efforts for customer and internal projects, with a focus on single-component optimization, circuit-level simulations, data analysis, and circuit layout.

**Key Responsibilities:**

*   Lead the design and layout of PICs for customer and strategic roadmap projects
*   Develop and maintain LIGENTEC’s design and layout libraries, ensuring adherence to best practices
*   Conduct industry-level circuit simulations and analyze large datasets
*   Contribute to the design of active components based on III-V and LNOI material
*   Develop and implement custom models to enhance design capabilities
*   Collaborate with cross-functional teams on process and testing to ensure successful project execution
*   Perform project feasibility analysis and contribute to project management
*   Provide mentorship to junior engineers and contribute to the overall design team growth
*   Provide concise and clear documentation and reporting

## Requirements

*   MSc or PhD in photonics or related fields.
*   Minimum of 7+ years hands-on experience in integrated optics design and layout in a top environment, preferably industrial
*   Problem-solver with a solutions-oriented mindset and critical thinking abilities
*   Adaptable and thrives in a dynamic environment with shifting priorities.
*   Collaborative team player and independent self-starter, capable of achieving both individual and group objectives
*   Excellent communication and reporting
*   Working proficiency in English

_Proficiency in:_

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

_Familiarity with:_

*   How PIC manufacturing affects design and layout: design-for-testability and design-for-manufacturability
*   Active components design and heterogeneous integration
*   Developing custom analytic and semi-analytic models

## 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 using reference 2512, 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.
