May 2015 The Physikalisch-Technische Bundesanstalt (PTB) is the National Metrology Institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science. At Department 3.3 "Thermophysical Quantities", we are looking for a graduate engineer specialized in mechanical or physical sciences to join us as of 15 June 2015. This position is available on the basis of a 3-year fixed-term contract. The remuneration will be paid in accordance with remuneration group 10 TVöD Bund. Your task:
Carrying out experimental work to further develop primary pressure standards
Tracing secondary pressure standards to primary pressure standards
Calibrating high-accuracy measuring instruments (measuring set-up, measurements, assessment, uncertainty analysis, associated processes such as clarifying technical issues with national and international customers)
Qualifications:
You have completed studies at a German "Fachhochschule" (University of Applied Sciences) or equivalent and have specialized in one of the above-mentioned subjects.
You have knowledge and practical experience in the fields of mechanics, metrology and materials technology as well as construction
You have general PC knowledge, basic knowledge of programming languages and of computer-aided instrument control.
You have an appropriate command of the English language to work with the relevant literature and communicate with our foreign visitors.
You have good communication skills and are ready to work in a team.
Experience in the fields of pressure measuring techniques, vacuum technique and uncertainty calculation would be advantageous.
Disabled persons will be given priority if they have the same occupational aptitude. PTB promotes the professional equality of women and men and is thus especially interested in applications from women.

[email protected]. doctoral candidate with a graduation in experimental physics, biotechnologies, physical chemistry or a comparable subject to join us as soon as possible. This position is available on the basis of a 36-month fixedterm contract. The remuneration will be paid in accordance with remuneration group 13 TVöD Bund (85 %). You will be employed at our Berlin site. Your doctorate will take place in cooperation with the Institute of Transfusion Medicine of the Charité Hospital in Berlin. Your future tasks will include:
The development of procedures of quality assurance for the manufacturing of a blood substitute, especially to quantify the methaemoglobin concentration in Hb microparticles, and the development of a concept for real-time measurement in production. The following investigations are planned:
Measuring the stray light distributions of (sub-) micrometre particles in the flow cytometer at various wavelengths.
Measuring the size distribution and concentration of Hb microparticles.
Measuring the collimated and the diffuse transmission as well as the diffuse reflection of cell suspensions and microparticles by means of a double integrating sphere set-up.
Designing (flow) spectrophotometric cells to modify the oxygen saturation in particle suspensions.
Modelling the measurement data by means of the Mie theory and by derivation of the optical properties of the Hb microparticles.
Determining the (relative) oxygen saturation in suspensions of Hb microparticles
