Military officials and medics said many others were wounded in the attack that targeted a crowd of soldiers gathered to collect their salaries near a base in northeastern Aden.
The attacker immersed himself among the soldiers crowding outside the house of the head of special security forces in Aden, Colonel Nasser Sarea, in Al-Arish district, near Al-Sawlaban base.
Sarea said the bomber "took advantage of the gathering and detonated his explosives among them, killing 30 soldiers and wounding several others".
The attack comes eight days after a similar bombing at Al-Sawlaban claimed by the Islamic State jihadist group killed 48 soldiers and wounded 29 others.
Yemeni authorities have for months pressed a campaign against jihadists who remain active in the south and east of the impoverished Arabian peninsula country.
IS and its jihadist rival Al-Qaeda have taken advantage of a conflict between the government and Yemen's Huthi rebels, who control the capital Sanaa, to bolster their presence across much of the south.
The two extremist groups have carried out a spate of attacks in Aden, Yemen's second city and headquarters of the internationally recognised government whose forces retook the port city from the Huthis last year.
No group claimed immediate responsibility for Sunday's blast.
Al-Qaeda has long been the dominant jihadist force in Yemen, located next to oil-flush Saudi Arabia and key shipping lanes, but experts say IS is seeking to supplant its extremist rival.
Washington regards Al-Qaeda's Yemen-based branch as its most dangerous and has kept up a long-running drone war against its commanders.
In August, an IS militant rammed his explosives-laden car into an army recruiting centre in Aden, killing 71 people in the deadliest jihadist attack on the city in over a year.
