Scarlett Moffatt and Mollie King have also joined the station as Radio 1 DJs hosting alongside Matt Edmondson.
Scarlett said: "I've always loved listening to Matt on Radio 1 so to present alongside him is going to be so much fun."
Maya Jama will join Radio 1 to host Radio 1's Greatest Hits on Saturdays (10am-1pm), and will also co-host with Scott Mills and Chris Stark Fridays, 1-4pm.
She said: "I'm so happy to be presenting alongside Scott Mills on Fridays. I'm sure I can learn a thing or two from him and beyond excited to have my own show on Radio 1 every Saturday, I cannot wait to start!"
Matt Edmondson will become the new host of the weekend 1-4pm show, and on Saturdays he will be joined by a monthly celebrity co-host with the likes of Scarlett Moffatt and Mollie King.
Mollie said: "I'm so excited to be co-hosting BBC Radio 1's brand new Saturday show with Matt Edmondson. He always has me in stitches; we're going to have a blast, bring it on!"
Matt added: "I am ridiculously excited about inviting some big name co-presenters to join me on Radio 1 every Saturday.
"I can't wait to work with Mollie and Scarlett, not to mention the 'reveal-them-and-you'll-be-immediately-fired' list of amazing names we have lined up for the rest of 2018."
Following multiple stints as a presenting duo in 2017, Dev and Alice Levine will officially join forces to co-host Radio 1's Weekend Breakfast show (weekends, 6-10am). Celebrity MasterChef finalist Dev, and Alice who is about to embark on a world comedy tour, will be waking up listeners from 17 March.

Jordan said: "What a great start to my 2018 – I'm absolutely made up! It's no secret that this has been a childhood ambition of mine, so to get my own show on Radio 1 and officially be part of the family is just amazing.
"To be honest, it's not properly sunk in, but I can't wait to be back on air and start presenting Radio 1's Greatest Hits."
Ben Cooper, Radio 1 Controller, said: "It's brilliant to welcome the next generation of superstars to Radio 1.
"Along with Maya, Jordan, Dev and Alice all starting new shows, Matt will co-present with the likes of Scarlett and Mollie, giving an exciting jeopardy to live radio at the weekend."
