He founded the engineering firm Stucky SA in 1926; based in Renens in Switzerland, it has been part of the Gruner AG group since 2013.

[2] From around 1915[a] to 1923, Stucky worked at the Basel office of Gruner AG, first as an assistant and later as head engineer and joint partner.

[4][5] At Gruner he developed calculation methods and introduced the parabolic shape and the notion of elastic deformation in double curvature arch dams during design of an arch dam impounding the Lac de Montsalvens reservoir in the Canton of Fribourg in Switzerland.

[12] In addition to his thesis, Stucky contributed to about 40 technical publications, including a reference work for specialists in concrete dams published in 1957 with Maurice-H. Derron,[14] and a 1961 article (written with his son Jean-Pierre Stucky and E. Schnitzler), summarising his work on the Swiss dams of Châtelot, Mauvoisin, Moiry, Malvaglia, Nalps, Luzzone, Limmern and Tourtemagne.

They had a son, Jean-Pierre Stucky, who also taught in the civil engineering department of the École Polytechnique Fédérale in Lausanne, specialising in reinforced concrete.
