He grew up in Petrograd until 1917, when his family moved to Petrovka in Tambov.  In 1929, the family returned to Leningrad, where his father got work as a meteorologist. 

In 1930, Semyonov-Tyan-Shansky moved to the Kola Peninsula as a research assistant and was then sent to the Lapland reserve to make scientific observations. Here he examined reindeer populations, was involved in the introduction of muskrats and beavers; and wrote several reports.

After the war, Semyonov-Tyan-Shansky worked at Leningrad at the Zoological Institute of the Russian Academy of Sciences, along with his wife, Maria Ivanovna Vladimirskaya, an ichthyologist . The couple went on several expeditions including to the Curonian Spit. In 1951 he worked at the Pechora-Ilych Nature Reserve while the Lapland reserve was denotified. He then worked to restore the reserve which happened in 1965. 

As an ornithologist Semyonov-Tyan-Shansky studied black grouse and studied the hatching of their eggs using a special instrument that he designed.
