Photonic Design & Optimisation Engineer

Tasks

LIGENTECs engineering team is searching for a Photonic Design & Optimization Engineer to drive the innovation of its Photonic Integrated Circuits (PICs). The successful candidate will be passionate about advanced design techniques component optimization and translating performance requirements into novel photonic structures.

Role and Responsibilities:

• Design and Optimization: Drive the design simulation and optimization of cutting-edge passive and active photonic components (e.g. couplers filters modulators photodiodes) for customer projects and strategic internal roadmaps focusing on RF and CW domains.
• Inverse Design: Explore and implement advanced design methodologies including inverse design and computational techniques to push the limits of component performance.
• Component Layout: Contribute to the hands-on layout of photonic components and circuits ensuring that the physical realization adheres to design intent best practices and manufacturing constraints.
• Performance Assessment: Critically assess the performance of designed components and circuits by analyzing complex experimental data feeding insights back into the design cycle.
• Feasibility Studies: Contribute to technical feasibility studies for customer projects defining the necessary component performance and architectural approach.
• Inter-team Collaboration: Interface with the Characterization Process and Yield Engineering teams to gather requirements capabilities and support the definition of test structures and test plans.
• Documentation: Provide concise and clear documentation and reporting on design methodology component performance and optimization results.

Requirements

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 is required to effectively contribute to component layout.
• Strong proficiency in Python programming for simulation optimization and data analysis. Familiarity with code versioning (e.g. Git) for collaborative software development is a plus.
• Expertise in dataset analysis from photonic components and circuits.
• Familiarity with active components heterogeneous integration and advanced design techniques (e.g. 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 and eager to learn and grow.
• Working proficiency in English.

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.
