About the role & the team
You will join the “cluster team” composed of 7 senior engineers, all reporting directly to our co-founder and CTO Sebastien.

- Manage and orchestrate Kubernetes-based clusters deployed in customer cloud environments (AWS, Azure, and GCP).
- Develop tooling and automation to provision, monitor, scale, and maintain managed customer clusters in real time.
About you & what we are looking for

- Experienced in Rust or C++ and Kubernetes
- Experienced in using Vortex is a plus
Working at Tsuga
- 🔥 We move fast. As an early-stage startup, we are pragmatic, we value ownership, and quick feedback over unnecessary process and hierarchy.
- 🙏 We solve problems, not blame people. When something goes wrong, we fix it, learn from it, and improve the system.
- 🛠️ We are builders. We start everything from a blank page and we lean on your colleagues' knowledge to move faster.
- 🙇 We are customer-obsessed. We dogfood Tsuga every day, so you care how the product is actually used and want to contribute ideas.
- 💥 We lean hard on AI, but not blindly. Our problems are hard and can’t be AI-slopped away.
- 🌍 We're international from day one. Every quarter, the whole team meets at our French office to align on company goals, celebrate wins, and connect with teammates from the US, UK, the Middle East, and across Europe.
