Jarvis served originally at the Royal Naval Hospitals of Plymouth and Haslar,^[2] before going on to serve at HMS Cochrane in Rosyth and then on board HMS Jupiter, HMS Ambuscade, HMS Berwick, RFA Argus and HMS Amazon. After qualifying as a specialist in General Medicine, Jarvis was appointed as the General Physician for RNH Gibraltar from 1982 to 1984.^[2] Following this he served in the 1990/91 Gulf Conflict on RFA Argus.

From here, he moved on to become the Commanding Officer (CEO) of the Royal Hospital Haslar (1999-2003, the UK's largest military hospital) and Fort Blockhouse (2001–03). He took Haslar through a period of substantial change, including merging it with a nearby military establishment and establishing partnership with the NHS. Jarvis served as an Honorary Executive Director of Portsmouth Hospitals NHS Trust during this complex period.

His numerous publications and lectures have covered many areas of global public health.

As well as serving on the Faculty Board of Clinical Radiology, on the UK National Information Governance Board, as part of the Academy of Colleges Information Group, and on a number of other national academic UK committees, Jarvis was the Chairman of the IT Committee of the Royal College of Radiologists.
