Onsite Development Engineer Simulation & Design – III/V Laser Diodes
Posted 4 hours ago
About the role
- Development Engineer for III/V laser diodes at Lumics GmbH, involved in simulation and design of structures for high-performance semiconductors. Join our team to innovate in laser technology within industrial applications.
Responsibilities
- Simulation and design of epitaxial structures (heterostructures) for III/V semiconductor laser diodes in the mid-infrared (MIR) range (GaAs-, InP- or GaSb-based systems)
- Development and optimization of quantum wells/films, barriers, waveguides and doping profiles with particular focus on brightness, efficiency and reliability
- Use and further development of simulation and design software (e.g. HAROLD, LUMERICAL, APSYS, MATLAB or comparable tools), including the development of in-house models where applicable
- Design, simulation and further development of chip and heterostructure designs for III/V semiconductor laser diodes based on physical models (band structure, carrier dynamics, recombination mechanisms, thermal management)
- Analysis of the physical relationships between epitaxial structure and the optoelectronic properties of the devices
- Validation of simulation results through close collaboration with process development and production
- Independent planning, execution and development of experiments for analysis (LIV measurements – cw/pulsed, near- and far-field measurements, etc.), and use of characterization methods such as PL, XRD, TEM, SIMS or TLM
- Collaboration with process development and production to transfer new chip and epitaxy concepts into series production
- Opportunity to contribute to and publish scientific results in internal and external specialist forums
Requirements
- University degree (Diploma, Master's or PhD) in Physics, Electrical Engineering, Materials Science or a related field with a focus on semiconductor devices
- Solid knowledge in the simulation and development of heterostructures for III/V semiconductors (band structures, transport mechanisms, quantum wells/wires, non-radiative mechanisms)
- Proven experience in the design of III/V laser diodes, ideally in the wavelength regions relevant to us
- Confident use of device simulation tools or willingness to develop own physical models/tools
- Basic understanding of epitaxial processes and their influence on device design is helpful but not a primary requirement for the role
- Enjoy analytical work, problem solving and interdisciplinary collaboration
- Very good written and spoken German and English
Benefits
- 30 days of vacation per year to maintain your work–life balance
- A highly varied and challenging role with plenty of scope for shaping your work at a modern site
- Flat hierarchies and short decision-making paths with lots of responsibility
- Flexible working hours
- Regular cross-team knowledge transfer
- Numerous additional benefits such as employee and shopping discounts, on-site canteen, sports facilities (e.g. volleyball court, on-site gym), bike leasing and regular company events
