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:

**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.
