A third of all nominees are female, up from a quarter in 2018, marking an important milestone for a traditionally male-dominated area of the music industry.
Desnos, Bennett and Mair will go head to head in the Breakthrough Engineer category, while Mair also receives a second nomination in the Breakthrough Producer of the Year category.
Elsewhere, Shura is in the running for the Remixer of the Year title, alongside Matthew Herbert and IYEARA.
The Album of the Year category will be contested by Nadine Shah (Holiday Destination), Arctic Monkeys (Tranquility Base Hotel & Casino) and Everything Everything (A Fever Dream).
Mastering Engineer of the Year shortlisters include Mandy Parnell, John Davis and Tim Young.
Cam Blackwood, Dave Eringa and James Ford are all nominated for UK Producer of the Year.
Catherine Marks (pictured above), the MPG’s 2018 Producer of the Year winner, said: ‘The MPG Awards are such a great event in our year as it gives us an opportunity to recognise the outstanding achievements of our engineering and producer community.
‘It was such an honour to win Producer of the Year in 2018, especially in a year where so many other women were acknowledged and awarded. I am looking forward to the MPG Awards next year and wish everyone who is nominated the best of luck.’
Final judging will take place at Abbey Road Studios in early December and the winners will be announced at a ceremony at Grosvenor House, London, on 28 February.
Now in its 11th year, the MPG Awards feature 16 award categories. Previous award winners include Sir George Martin CBE, FKA Twigs, Roni Size, Sylvia Massy, Brian Eno, Trevor Horn and Dave Stewart.
