In 2000, Dom joined the Foreign & Commonwealth Office. He advised on a wide range of briefs, including UK investor protection, maritime issues, counter-proliferation and counter-terrorism, the UK overseas territories and the international law of outer space.
In 2003, Dom was posted to The Hague to head up a new team, focused on bringing war criminals - including Slobodan Milosevic, Radovan Karadzic and Charles Taylor - to justice. On return to London, he advised on the Arab-Israeli conflict, EU law and Gibraltar.
Dom left the FCO in 2006, and worked for three years as Chief of Staff to respective Shadow Home and Justice Secretaries, advising in the House of Commons on crime, policing, immigration, counter-terrorism, human rights and constitutional reform.
