The large retailer announced the decision today on the back of yesterday's opening of its 500th convenience store in Southsea, Hampshire.
Sainsbury's is opening convenience stores at the rate of one a week and plans to add 100 more every year for the next three years.
Simon Twigger, Sainsbury's director of convenience, said: "Opening our 500th store is a real milestone in our plans to create a scale convenience business.
"The jobs announced today will range from managerial and team leader roles to customer service.
"Work in our convenience business is particularly fast-paced and flexible, with great opportunities for progression. It's one of the best possible starts to a career in retail and many of our convenience store managers have worked their way up into the role."
