Phy­si­ka­lisch-Tech­ni­sche Bun­des­an­stalt

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.

With a start­ing date as soon as pos­sible, Depart­ment 8.2, Biosig­nals, is look­ing for a can­did­ate to fill the fol­low­ing pos­i­tion at PTB’s Ber­lin-Char­lot­ten­burg site for a dur­a­tion of two years:

Doc­toral can­did­ate or postdoc in the field of quantum sensor sys­tems
for med­ical pur­poses

up to Remu­ner­a­tion Group 14 TVöD Bund | full-time (39 hours/week) | fixed-term con­tract

Working field:

As part of the team of Work­ing Group 8.21, Optical Mag­neto­metry, you will design and assemble a quantum sensor sys­tem for ima­ging ultra-low mag­netic fields. The sys­tem will be based on the prin­ciple of optic­ally pumped mag­ne­to­met­ers (OPM). A suit­able arrange­ment of laser light beams and a spa­tially struc­tured spin ensemble will enable spa­tially resolved mag­netic field ima­ging. As part of your work, you will employ this sys­tem to non-invas­ively meas­ure bio­mag­netic fields, arising for instance from mus­cu­lar activ­ity (mag­netomyography), or to loc­al­ize mag­netic nan­o­particles.
Your tasks will include:

  • Devel­op­ing and assem­bling a multi-chan­nel quantum sensor sys­tem (beam-shap­ing optics, lasers, spec­tro­scopy cells, opto­elec­tron­ics)
  • Optim­iz­ing the indi­vidual com­pon­ents of the sys­tem in cooper­a­tion with national and inter­na­tional part­ners
  • Multi-chan­nel field record­ings and the integ­ra­tion of field recon­struc­tion meth­ods
  • Present­ing the res­ults at national and inter­na­tional con­fer­ences, and pub­lish­ing them in sci­entific journ­als


  • Uni­versity degree (mas­ter/dip­loma) in exper­i­mental phys­ics or a com­par­able engin­eer­ing sub­ject with the grade “very good” (postdocs: doc­tor­ate)
  • You are inter­ested in devel­op­ing and apply­ing quantum sensor sys­tems.
  • You are highly com­mit­ted and able to per­form goal-ori­ented sci­entific work.
  • Good know­ledge of and exper­i­mental exper­i­ence in atomic and quantum phys­ics, laser spec­tro­scopy, optical ima­ging or related fields would be of advant­age.
  • Ideally, you have pro­gram­ming skills, e.g., in Python, C++, Mat­lab, Math­em­at­ica.
  • You are phys­ic­ally fit to work in an optics labor­at­ory.
  • You are a strong team player with excel­lent com­mu­nic­a­tion skills
  • You have a very good com­mand of both spoken and writ­ten Eng­lish.
  • You are will­ing to travel within Ger­many and abroad within the scope of your assign­ment

What we offer:

  • A pos­i­tion at one of the world’s lead­ing research insti­tu­tions with an excel­lent infra­struc­ture
  • Out­stand­ing national and inter­na­tional net­work­ing
  • Intens­ive super­vi­sion of your doc­tor­ate in an inter­dis­cip­lin­ary team
  • Remu­ner­a­tion in accord­ance with the Col­lect­ive Bar­gain­ing Agree­ment for the Pub­lic Ser­vice cov­er­ing fed­eral employ­ees (Tari­fver­trag öffent­licher Dienst Bund – TVöD)
  • Com­pat­ib­il­ity of fam­ily life and work (flex­ible work options and part-time schemes)
  • Vari­ous work­place health and well­ness options
  • 30 days of paid annual leave
  • Excel­lent pub­lic trans­port­a­tion con­nec­tions and a sub­sid­ized transit pass (VBB-Firmenticket)
  • Free park­ing for cars, motor­bikes and bicycles
