Scientists (all genders) - GaN Components, Circuits & Modules

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research units throughout Germany and is a leading applied research organization. Around 32 000 employees work with an annual research budget of 3.4 billion euros. 

SHAPING THE FUTURE — TECHNOLOGICALLY and PROFESSIONALLY.
At the Fraunhofer Institute for Applied Solid State Physics IAF we know our technologies like the back of our hand. Because we are one of the few scientific institutions worldwide to conduct research along the entire semiconductor value chain and on tailor-made synthetic diamonds. Whether high-frequency circuits for communications technology, voltage converter modules for electromobility, laser systems for measurement processes, or innovative hardware and software for quantum computers and quantum sensors: we develop tomorrow’s technology in-house for a sustainable and secure society. When will you join us?

 

What you will do

The Microelectronics (ME) department designs microelectronic components and circuits for high-frequency technology and power electronics. Systems for sensor technology, communication technology, and power electronics are developed based on high-frequency modules. We are also equipped with state-of-the-art measurement technology.

Your tasks will include:

  • With us, you will develop, design, and implement high-performance GaN components, circuits, and modules for high-frequency applications up to 10 GHz.
  • Your expertise will contribute to the realization of groundbreaking high-frequency systems, communication solutions, and radar technologies.
  • You will be actively involved from the concept phase to characterization and will contribute your ideas to exciting projects.

 

What you bring to the table

  • Completed degree (diploma or master's) in electrical engineering, microsystems engineering, or communications engineering, ideally with a PhD
  • Comprehensive knowledge of system design for high-performance RF components, e.g., with signal flow diagrams, calculation of required power, gain, and efficiency
  • Experience in the design of hybrid high-frequency modules up to 10 GHz
  • Confident use of circuit simulation programs and EM simulation tools (ADS, CST, HFSS)
  • Expertise in the metrological characterization of semiconductor components, for example through S-parameters and load pull
  • Experience in research and industrial projects, ideally in a leadership role
  • Business fluent German and English skills as well as team spirit, strong communication skills, and an independent scientific approach to work

 

What you can expect

  • Access to state-of-the-art research infrastructure with the latest technology in high-frequency electronics
  • Committed collaboration with innovative teams and industry on exciting projects
  • Freedom for creativity and the opportunity to shape your own research and actively participate in scientific exchange
  • Comprehensive development opportunities through a wide range of training courses and participation in international conferences
  • A variety of additional benefits, including a company pension plan (VBL), a subsidy for the DeutschlandTicket, and health services
  • Family-friendly workplace with daycare places at the “Junikäfer” daycare center in Freiburg, a child-friendly office, mobile working and extensive counseling services for home and elder care (pme Familienservice)
  • Free parking garage, e-charging stations and Frelo station (bike rental system) and bus stop directly at the institute

 

The weekly working hours are 39 hours. The position is initially limited to three years. 

We value and promote the diversity of our employees' skills and therefore welcome all applications – regardless of age, gender, nationality, ethnic and social background, religion, ideology, disability, sexual orientation, and identity. Severely disabled persons will be given preference if equally qualified. Our tasks are diverse and adaptable – for applicants with disabilities, we work together to find solutions that optimally promote their abilities. The same applies if they do not meet all profile requirements due to a disability.

With its focus on key technologies relevant to the future and the exploitation of results in business and industry, the Fraunhofer Society plays a central role in the innovation process. As a guide and catalyst for innovative development and scientific excellence, it helps shape our society and our future.

Ready for change? Then apply now and make a difference! Once we have received your online application (cover letter, resume, relevant certificates), you will receive an automatic confirmation of receipt. We will then contact you as soon as possible to let you know how to proceed.
