SRE - CDI Paris - Theodo Cloud

About the role

Theodo Cloud represents a dedicated practice within Theodo Group focused on DevSecOps, specializing in the design, construction, and management of cloud infrastructures. The mission is to assist both scale-ups and large enterprises in resolving business challenges through technological innovation. As a pioneer in containerization, Theodo Cloud positions innovation at the core of its approach. The practice develops offers targeting current industry challenges, including accelerating cloud migrations and modernization using AI, building and managing regulated industry environments (such as HDS for healthcare and SecNumCloud), and unlocking the full potential of Large Language Models (LLMs) while optimizing performance, costs, and industrial security.

The SRE role is embedded within this structure. Theodo Cloud is a young entity where it is possible to build things and invest in personal motivations. Beyond the project, dedicated time is allocated for initiatives related to team training, diversity, or technical recruitment. The evolution roadmap leads first to a Lead position, then to specialized tracks in Management or Expertise. The methodology is based on Lean Tech®, which emphasizes continuous learning and places human development before product development.

This SRE position is intended for curious individuals who wish to rapidly increase their skills, working with a wide range of infrastructures and tools (AWS, GCP, Azure, Scaleway, Outscale, OVH, etc.) and complex bugs in production.

About the role

You are a Software Engineer who will design, implement, and operate cloud infrastructure as part of Theodo Cloud practice. You will work hand in hand with a Lead DevOps and an Agile Project Manager to ensure impactful delivery for clients in both build and run contexts. You will react to production incidents, run technical investigations, and own post-mortems with clear and structured communication. You will translate business needs into reliable infrastructure, leveraging cloud platforms and automation to remove bottlenecks and accelerate delivery. You will actively contribute to an environment where infrastructure is a growth lever rather than a constraint.
