Mitchell will oversee defence duties until the conclusion of next year's World Cup, after being recruited as Paul Gustard's replacement in a total package costing the RFU in the region of £500,000.
The former All Blacks chief has amassed 24 years of coaching experience, including three years working beneath Sir Clive Woodward from 1997-2000. Virtually ever since his time with England, he has only ever served as a head coach - including time at Sale Sharks.
Jones has signed a two-year contract extension that expires in 2021 - subject to performance at the World Cup - but Mitchell has distanced himself from the possibility of filling any vacancy created by his long-term friend.
"People will speculate but that's not even on my mind. I have a job to do and I'll do it the best I can," Mitchell said.
"I'm really looking forward to getting into it, which has already started. I'm on a one-year contract and I will fulfil that the best I can.
"Whatever happens after that, I will decide, but there is certainly no talk or ambition around that situation. I've just got to deal with what's in front of me now."
Jones and Mitchell were adversaries at the 2003 World Cup, the former in his role as Wallabies head coach, and they have stayed in touch since, showing each other "empathy during difficult times, in sickness".
The two met during England's June tour to South Africa and Mitchell agreed to join the management team, leaving the Rugby Football Union to negotiate his release from the year left on his Blue Bulls contract.
Mitchell will however remain in in South Africa during his time coaching England, commuting over to the UK.
"Coaching England was special back then and it's special now. It's nice to come back with more maturity and miles on the tyres," Mitchell said.
"I'm indebted to English rugby because my first five years coaching were in this country. It is like going to school for the first time."
