Research Scientist Electrical Engineering, Physics, Computer Science, Engineering Sciences (26-112-4B)

The art of measurement — made in Germany. Striving to perfect it is the mission of the 2,100 employees of PTB, the Physikalisch-Technische Bundesanstalt. As Germany’s national metrology institute and a leading center of research, we operate in an international environment to develop world-class measurement standards. We at PTB work to ensure that people and organizations can trust the measurements they use.

At our Braunschweig site, starting on November 1, 2026 we are looking to fill the following position in Department 4.5 (Applied Radiometry):

Research Scientist

Electrical Engineering, Physics, Computer Science, Engineering Sciences

Remuneration Group 13 TVöD Bund ○ for a fixed term until July 31, 2027○ Full-time

Your tasks:

Working Group 4.51, ‘Reflection and Transmission’, investigates how different materials reflect or transmit radiation across the spectrum from the ultraviolet to the near-infrared. To this end, highly accurate calibration methods for measuring the reflection and transmission properties of optical components are being developed and continuously improved. Clients and collaborative partners include, amongst others, the aerospace industry, the automotive industry, the printing and paper industry, pigment and materials manufacturers, and manufacturers of measuring instruments in the optical industry. As part of the EU-funded research project “xDDiff – Multidimensional optical diffusion for the measurement of appearance”, the aim is to determine the diffuse reflection and transmission properties of complex surfaces.

Your activities will include:

• Completing work already underway, in particular the evaluation and interpretation of measurements of diffuse reflection/transmission properties (BRDF/BTDF)
• Further developing existing measurement set-ups in terms of both hardware and software
• Presenting the results at project meetings and scientific conferences in Germany and abroad, as well as preparing scientific publications
• Preparing the final reports required by the project

Your profile:

• A university degree (Diplom/Master’s) in physics, engineering, electrical engineering or a comparable subject
• Strong experimental skills
• Experience in the development and construction of optical apparatus
• Experience in photometry and radiometry, particularly in measuring reflection and transmission properties
• Experience in carrying out and evaluating BRDF and BTDF measurements is an advantage
• Experience of participating in projects with an international consortium
• Knowledge of metrology, measurement data analysis and uncertainty analysis
• You have achieved B2 level in English and A2 level in German
• A structured, independent and results-oriented approach to work
• Strong teamwork and communication skills
• You are willing to travel for work both in Germany and abroad

We offer:

• Challenging research and project work with national and international relevance
• Working with state-of-the-art research infrastructure in an environment of scientific excellence
• Opportunities to shape your own work and work independently
• Flexible working time arrangements, family-friendly working conditions and pay in line with collective agreements
• Targeted professional development and training programmes, as well as opportunities for specialist development
