Goal: Build better, more scalable, and more enjoyable messaging and communication services.

- Continuously improve our distributed architecture

- Work closely with QA, PM, UX, and Front-End teams to deliver meaningful features

- Optimize performance, scalability, and code quality

- Take an active role in technical and product decisions — not just execute

- And of course, code with autonomy, curiosity, and pragmatism

What we’re looking for :

- 3+ years of experience with Go (Golang) — that’s your foundation
- Some experience with Kotlin? Perfect — our Messaging stack runs on Kotlin
- Solid understanding of microservices, REST/gRPC APIs, scalability, and performance
- You like understanding the “why” behind the “how”
- You enjoy teamwork, sharing ideas, and challenging others constructively

- You are fluent in french/ english

Why you’ll love working with us :

- A tech team that’s evolving fast — with real room to experiment

- High-impact projects (lots of traffic, lots of challenges)

- Technical, empathetic management — we speak your language

- An environment where autonomy, quality, and collaboration actually mean something
