We are looking for a postdoc or staff scientist to work on experiments on cold alkali atoms integrated with nanophotonics devices for research into trapping and nonlinear optics/single photon generation. Position is for 2 to 4 years, depending on the candidate and can be at a junior (postdoc) or senior (staff scientist, 5 years post-PhD) level. The successful candidate will join an existing experiment to work with the PhD students and other researchers. Staff scientist positions may be extended further.
