Job Summary
The Senior Development Engineer will drive the design and optimization of epitaxial stacks for VCSEL and related photonic device structures. The role focuses on translating devicelevel requirements into robust epitaxial designs using advanced semiconductor physics and numerical simulations to guide development and optimize performance yield and reliability. This position is ideal for someone with a strong academic and/or R&D background in semiconductor physics and photonic devices who wants to work at the interface of epitaxy device design and product development.
Key Responsibilities
- Design and simulate epitaxial layer stacks for VCSEL and other photonic device structures to meet optical electrical and thermal device requirements.
- Develop and refine device and epitaxy simulation models (e.g. optical cavity / mode simulations carrier transport thermal behavior) to support architecture decisions.
- Translate system and device requirements into epitaxial specifications (materials layer sequences thicknesses doping profiles).
- Work closely with epitaxy process and device characterization teams to:
Define experiments and DOEs. Interpret measurement and reliability data. Iterate designs based on feedback from wafer- and devicelevel results.
- Contribute to device architecture and development strategies including roadmaps for performance reliability and manufacturability improvements.
- Analyze and correlate simulation epitaxial and device performance data to identify root causes and optimization paths.
- Prepare and present technical reports design reviews and development status updates for internal stakeholders.
- Collaborate in a multidisciplinary international R&D environment coordinating with colleagues across different locations and time zones (with substantial overlap to EU working hours).
- Mentor junior engineers and students in topics such as semiconductor device physics simulation methodology and data analysis.
Qualifications :
- PhD in Materials Science Physics Electrical Engineering or a closely related field.
- Extensive professional experience with a strong record of sustained impact and increasing responsibility in R&D or applied academic research ideally including collaboration with industry partners or participation in translational initiatives.
- Solid track record in semiconductor devices preferably in photonic devices such as lasers LEDs or VCSELs.
- Deep understanding of semiconductor physics including:
Heterostructures and quantum wells. Optical cavities and resonant structures. Carrier transport recombination mechanisms and thermal effects.
- Experience with device or epitaxial stack simulations for example:
Optical mode / cavity simulations. Electronic band structure and carrier confinement. Thermal / electrothermal simulations.
- Strong ability to interpret experimental data (e.g. IV LI spectral farfield lifetime/reliability data) and connect results to physical mechanisms and design choices.
- Fluent English (spoken and written) with the ability to write clear technical documentation and present complex topics to a mixed audience.
- Ability and willingness to work at least partially in EU time zones to ensure effective collaboration with European teams.
