Senior Fullstack Developer (Go/React)

About us
Our ambition is to turn our clients into Media Owners by scaling up tools, messages, services & audience interactions.

Since 2013 our sole focus has been to deliver solutions that help brands speed up their engagement strategy transformation for workforces (improving employee engagement thanks to internal communication) and clients (driving sales thanks to in-store communication).
We started with offline communication on screens placed in offices or in stores (Digital Signage) and recently increased the reach of their communications, adding an online layer to our customers.

We have been experiencing great growth both internally and externally after raising €2.5M in 2017 and acquired in 2023 a company specialized in the video creation to improve our creation module as well as our service capacity to continue helping our customers solve their problems via software AND service approach.

News flash :
We just acquired Neotess (Dedicast), a digital signage expert based in Saint-Étienne. With this acquisition, Cenareo continues to accelerate!
We are building bridges between our areas of expertise to create a global leader, empowering the strategic communications of brands through Media Equity.

Our 85+ people company has been profitable since 2022 and is located in France (60+people in Toulouse (Headquarter), Paris and Saint-Etienne), and inTunis (25 people).

Our culture is ultra strong and oriented around:
● The Champion’s league mindset (we are always looking for being better individuals and achieving better results) for our team but also through our solutions
● The Concern for others (we care about our employees, altruist, mutual respect and listening are musts)
● The Client and service focus (we don’t want to be solution provider, we want to team up with our customers and are eager to better understand how they are using our solutions to improve it and help them achieve better results)
● The Assertiveness (the feedback culture is essential, we challenge with confidence, and we value initiatives)

The Mission & Context

We are looking for a highly skilled Senior Fullstack Developer to join our technical team. You will be a key player in evolving our core product, intervening in the most complex technical aspects while ensuring the robustness of our existing systems.
As a senior member of the team, you will not only ship high-quality code but also act as a mentor, helping to elevate the collective technical level of the engineering department.

Exciting? We think it is too... But one word of caution. Whilst technical excellence is seen as a key expertise in our organization all the way to the board level, this role isn’t for everybody. Why?

• Because we value the hunger to learn over the illusion of knowing it all, you'll fit right in if your curiosity is bigger than your ego. And you will need to be too.

• Because our team thrives on collective problem-solving and radical humility. And you will need to be too.

Still interested? Do read on.
