Let's talk

Manifeste Extia profile=extian (fr-en)

Oscar Wilde - *Be yourself, everyone else is already taken*

You're recruited for who you are. You shouldn't try to invent a character and be like someone else. On the contrary, be yourself and let your personality shine through: it will save your time and that of others. In other words, cultivate your garden and grow your talents.


Be yourself

*"Interactions first, processes second"* -- Agile Manifesto 

We could have the best tools, processes and products on earth, but nothing can ever replace good working relationships. 

And this means very simple things: 

- **A smile**: on the phone, in a corridor (and even on public transport!), a smile is heard, seen, and sends positive vibes towards the other person. 

- **Feedback:** if you have something to say, say it nicely. Speak with kindness. If someone gives you feedback,see it as an opportunity to improve.

- **Responsiveness**: there's no point in sweeping problems under the carpet. Learn to deal with your irritants and those of others without delay. But how? Simply by communicating.


Build quality working relationships

 *"As for the future, your task is not to foresee it, but to enable it"* - Antoine de Saint-Exupéry

Extia Engineering is YOUR company. Each and every one of us is responsible for making it an innovative, friendly and successful company. You'll never be criticised for having ideas. On the other hand, no “easier said than done”, meaning no problem without a solution! Is there something you think isn't working? Got an idea you'd like to put forward? Just say the word and join in the global drive for continuous improvement.


Commit to a dynamic of continuous improvement

*“Genius is one percent inspiration and ninety-nine percent perspiration”*- Thomas Edison

After all, we are competitors at heart. We want to succeed, win and do better than yesterday. Over and above results, we value effort and hard work. Because in the end they always pay off.


Do the best you can every day

*“We’re not working - we’re playing”*- Arnaud Frey

Should we really comment on the words of the CEO of Extia Engineering? 😉
If you have any doubts, head over to him!


Have fun

*"I never lose, I either win or I learn"* - Nelson Mandela


The good news is that you are not perfect. So it's likely (and sometimes desirable) that you will make mistakes, make bad decisions and sometimes take the wrong path.

The important thing for us is :
- Don't hide your difficulties so that others can help you without wasting time : "fail but fail fast".
- Learn from your mistakes so as to avoid making the same ones over and over again.

Learn from your mistakes

*‘The one who does is the one who knows’* - Maxime Extia Engineering

We trust you. Of course, at the beginning, you'll have objectives and metrics to respect. Don't forget that you have the chance to benefit from feedback from everyone who has done the job before you. These metrics are there to help you structure your activity and give you a frame of reference. Once you've mastered the fundamentals of the job, you'll be able to move away from the framework and find your own style. But before that, stay humble, work and learn.

Trust yourself and us

First who (fr-en)

In a constantly changing world, it's up to each individual to come up with solutions to meet the challenges of daily life. Our strategy is to build meaningful projects with the right people.
This intrapreneurial approach, firmly focused on people, influences Extia Engineering's business model on a daily basis.

We like to say that all great stories begin with a meeting. “First who, then what!” focuses on what each candidate can and wants to bring to Extia Engineering. For us, personality, potential, and commitment to driving a project are more important than skills. We start with the individual and co-create a meaningful professional project with them.

In a constantly changing world, it is up to people to find simple and effective solutions to adapt to reality. This insight serves as our strategy: surround ourselves with the right people to co-create meaningful projects.
