Senior Full Stack Engineer - Contract - Backend Leaning   THIS CONTRACT IS INSIDE IR35.   A bit about us… Ask people where Nando's comes from and you'll get a different answer every time. Portugal? Mexico? The UK? Our story actually starts in Rosettenville, a Portuguese neighbourhood in Johannesburg, South Africa. With stops in Mozambique and the UK along the way.   It was 1987 and Robbie Brozin and Fernando Duarte opened their first chicken restaurant. Then another. And then another.

We care as much about them as we do our legendary, flame-grilled PERi-PERi - because it's...
