Kimi Raikkonen

 Ex-F1 driver, 2022 Indycar 500 miles of Indianapolis race winner: 

“Julien is a hardworking and passionate engineer. We worked together for 2 years in 2017 and 2018 and he helped me push myself to the next level of my driving. On top of being very technical and experienced what I really liked with Julien was the personal interaction. We would spend a lot of time before, during and after events analyzing and try and together figure out how to become better. He would never give up and always have your back. He is also very honest and direct when needed to make sure things happens. I’ve worked with many engineers throughout my career and I can honestly say Julien is one of the very best in the business. A racer at heart that will give everything to succeed. I really enjoyed working with Julien and I strongly feel he would be a big asset to any racing team/driver/organization.”
 

 Ex-F1 driver, F1 race winner, GP2 Champion:

"I worked with Julien in GP2 in 2007 where I won the Monaco GP, one of my best racing memory to date. We then worked together again in Lotus F1 in 2014 and Julien always showed passion, dedication and drive to make me better as a driver and to improve car performance. We had a great and successful relationship together.“
 

Digital & Social Media manager, Ferrari F1 Team:

“Working with Julien (JSC7 engineering) has been a pleasure since day 1. I joined Sauber with no experience in the industry and Julien has been always incredibly kind, spending all the time necessary to help me learn a lot of technical details that were of great help in the development of my functions. He has also been extremely supportive with all the social media and digital activities by participating in many content initiatives dedicated to fans and guest. He is a friendly, funny person, with a great career behind him and always willing to help others. I will keep great memories of these 3 years working with Julien.

Ex-F1 driver, GP2 Champion:

 “It was a pleasure working alongside Julien at Renault in 2016. As my race engineer we formed a great working relationship. It goes without saying that Julien has superb knowledge and experience in engineering, but more than that, I think he was able to get the most out of others in the team as well with his clear ideas and passion for success, which certainly contributed well to our successful partnership.”

Indycar driver, ex-F1 driver and multiple podiums scorer, GP2 Champion: 

“I've been working with Julien in 2015, through my last year at Lotus. We had a very successful year, including my last podium in Formula 1, with a team that was struggling financially. This never affected our work. Julien was very good at listening and understanding the driver mentality and spirit at every race. Engineering the car is great, but the key to extract the maximum of a race weekend is to engineer the car for the driver and making sure that both work together. I feel that's what we did during our time and that was particularly enjoyable.”

 Head of Race Strategy at Alpine F1:

"I know and worked with Julien (JSC7 engineering) back in our Renault & Lotus days in formula one, he is a first-class experienced track engineer and a valuable team player beyond this. I hope our professional paths will cross again one day."

 Engineering Director at Aston Martin F1 Team:

"Julien is a very experienced Race Engineer with a proven track record with many different F1 world teams and with different drivers, including World Champions. He copes well under very demanding and stressful situations. 

Julien has a very good understanding of the car performance, using a mixture of analytical and common-sense approach, and he is a real Team player. On a personal level, Julien is very sociable, approachable and has a good sense of humor."

 Head of Vehicle Dynamics at HWA AG:

"Julien is a massively experienced trackside engineer, who has worked at the top level in motorsport both as a Performance Engineer and as a Race Engineer. Julien works well with drivers and has a good technical understanding of the racing car. Plus, maybe most importantly, he is a great person to work with on a personal level."

Lean Leadership Consultant

"I started working with Julien on one of my projects to improve overall people performance and engagement and introduce Lean Leadership behaviors. Julien took on board each idea and process introduced and developed it into his own style for his specialist job role and then F1 world championed it within his direct team. Embracing such aspects such as situational Leadership and Belbin Team roles for the greater good of the team. Julien is a leader that says it as it is but ultimately this can be invaluable in raising the bar to human performance. 

Julien will bring you openness and honesty to any engagement coupled with a huge amount of knowledge. A pleasurable three years working together."

 Former Head of Audi Motorsport at AUDI AG:

"I have known Julien for many years now and I remember giving him his first opportunity in F1 back in 2007 where I was impressed by his motivation but also his technical knowledge for his age at the time. He started in the test team with us at TMG but quickly moved into the F1 world race team working with Jarno Trulli as Performance Engineer. When Toyota shut the F1 operation in 2009 we both moved in the UK to work for the newly created Lotus Racing. Julien has always shown passion and dedication for his job as performance and race engineer. He has now forged a long and successful career in F1 working with several different teams and drivers. On a personal level, Julien is a very easy going person and a very sociable character and we stayed in touch over the year despite not working together anymore. I can only strongly recommend him to any company."

 Head of Engineering Quality at Alpine F1:

 "Julien is an expert senior engineer with a wealth of trackside and vehicle dynamics experience. The combination of theoretical knowledge and practical application makes him a formidable prospect for any motorsport organization. Julien's (owner of JSC7 engineering) experience is thanks to his strong dedication to motorsport, particularly trackside operations. He shows strong leadership skills and remains calm and calculated under extreme pressure."

Head of Data and Computational Science at Sauber Motorsport AG

" Obviously Julien is highly experienced in the top-level motorsport industry and specifically as a race engineer. I worked together with him for several years at Sauber Motorsport / Alfa Romeo F1 Team, where he was one of the stakeholders of Sauber’s simulation and analysis tool chain. The communication with Julien has always been very efficient, calm and precise. I always appreciated his input and feedback. His approach is equally analytic and pragmatic in all situations."

 Head of U.S. Operations at Red Knot Communications:

"Julien is a highly skilled, senior motorsport race engineer. He’s worked at the top of the global motorsport industry for many years and commands the respect his seniority and track record dwarves. He’s easy to work with, has a positive attitude and is a professional, team player - a must in Formula 1. I can’t recommend him highly enough."

Kimi Raikkonen's manager:

 "Julien has been working with us Formula Management Ltd. (Kimi Räikkönen F1 driver) for the period of 2019-2021. It has been pleasure to work with him and gain as good results as was possible and available under his guidance/knowledge as a race engineer for Kimi Räikkönen during those years in Alfa Romeo Racing Orlen. He is very open/civilized/easy to communicate with and a true professional. "

Head of Vehicle Performance Group:

"I worked with Julien at Sauber F1 (which became Alfa Romeo Racing) for 3 1/2 years. In that time Julien demonstrated a very good understanding of what was needed to help drivers deliver their best at each race event. He worked well with Kim Raikkonen and Marcus Ericson, always keeping calm and managing the situation well, no matter what was happening around him. He has a good understanding of what he needs from a racing car and how to get it to happen. This balanced view of the driver and the car will work very well at the next team / company to employ him."
