Later, he assumed significant responsibilities as Acting Deputy Chief of Ordnance and subsequently as Deputy Chief of Ordnance until 1926. Promoted through the ranks, he eventually commanded the Boden Artillery Regiment in 1926 and the Göta Artillery Regiment in 1930 before becoming a major general in 1933. His career culminated in appointments such as Master-General of the Ordnance and chief of the Swedish Army Ordnance Corps in 1934, leading to his retirement as a lieutenant general in 1939. Osterman also played a pivotal role in the establishment of the Swedish Association of Army, Navy, and Air Force Officers and served as its first chairman from 1932 to 1936.

Osterman was commissioned as an officer in 1894 and was assigned as a underlöjtnant to the Jämtland Ranger Regiment in Östersund. He transferred to the Norrland Artillery Regiment in Östersund in 1895, where he was promoted to lieutenant in 1898. He attended the Artillery and Engineering College's advanced course from 1898 to 1900 and served in the Artillery Staff from 1902, being promoted to captain in the Norrland Artillery Regiment in 1904. Osterman, who was an artillery specialist, held key positions within the artillery. As an artillery staff officer, he was the head of the Artillery Department's Construction Section in the Royal Swedish Army Materiel Administration from 1908 to 1912 and from 1914 to 1915. Immediately thereafter, he served as the Acting Deputy Chief of Ordnance and held the position of Deputy Chief of Ordnance from 1915 to 1926.

He retired and was given a tombstone promotion to lieutenant general in 1939.
Osterman was a judicious and skilled technician and a prominent organizer, by nature objective, factual, and thoughtful. When the Swedish Association of Army, Navy and Air Force Officers (Svenska officersförbundet) was formed in 1932 with the task of safeguarding the interests of the officer corps, especially in financial matters, Osterman was elected as its first chairman and remained in that position until 1936.
