Coming to England in 1903, he studied at the London Hospital and served as senior clinical assistant at the Golden Square Throat Hospital; he was elected assistant surgeon to the Central London Throat Hospital in 1908. Muecke was appointed to the staff of the London Hospital as aural registrar and demonstrator in 1909, and took the Fellowship that year, though not previously a Member. He was elected assistant aural surgeon, 1918, aural surgeon, 1923, and consulting surgeon to the ear, nose, and throat department on his retirement, 1936. At the Golden Square hospital he was elected assistant surgeon shortly before the outbreak of war in 1914, but having joined the RAMC he was away from London for almost the whole period of this appointment. He saw active service at Suvla Bay, Gallipoli, 1915, on the Somme, 1916, and afterwards at Arras and Passchendaele, and was mentioned in despatches. He then transferred to the RAFMS, as ear, nose, and throat specialist, with the rank of lieutenant-colonel. He was awarded a military CBE, 1919.

He died in the London Hospital on 13 April 1945, aged 65. He had practised in Queen Anne Street and later at 36 Cavendish Square, and retired to The Greenings, Charlwood, Surrey, where he enjoyed farming and rough-shooting.
