Senior Site Reliability Engineer, Implicity

• We are looking for a senior engineer who has seen production get rough, keeps a cool head when it does, and wants to help reshape the platform
• Significant experience in infrastructure / ops / SRE, ideally with a background that goes beyond cloud (e.g. sysadmin who grew into cloud)
• Real production run experience: on-call, critical incidents, and the ability to stay calm and structured under pressure
• Solid hands-on experience with AWS in production
• Infrastructure as Code with Terraform
• CI pipelines (GitLab CI, GitHub Actions or similar)
• Willingness to work on GCP as we move to multi-cloud
• Fluent English; French is a strong plus
• You say things as they are: you raise problems early and constructively instead of smoothing them over
• You treat other teams as your clients: you listen, you explain, you support
• You welcome feedback and challenge yourself
• You enjoy transformation projects and like bringing strong, well-argued proposals
• You use AI tools as part of how you work

Desirable

• You will join the Infra/Platform team: four engineers led by Cyrille, our DevOps & Infrastructure Engineering Manager. They own the entire infrastructure and the stability of the platform, and they are the go-to technical partner for every team at Implicity, tech and non-tech alike. The team works in Kanban, with a quarterly view on the projects other teams bring us, plus a daily stand-up and weekly 1:1s
• We are moving from a team that reacts to requests to a team that provides a real service to the rest of the company. Our infrastructure was designed in 2017, and with scale-up and the US market as priorities, 2027 is a year of transformation
• Build, evolve and maintain our cloud infrastructure as code (Terraform on AWS)
• Own and improve CI/CD, automation, observability and monitoring
• Keep the platform stable: take part in run activities, handle incidents and drive post-incident improvements
• Act as a technical reference for other teams: assess new technologies, validate technical choices and integrate new building blocks
• Take an active part in our 2027 projects: Terraform refactoring, Kubernetes and containerization overhaul, a move to multi-cloud, and a fresh look at our core stack (MariaDB, RabbitMQ…)

• Call with our Talent team (about 30 min, video conference)
• Technical interview with Cyrille, DevOps & Infrastructure Engineering Manager (about 1h30, video conference)
• Team meeting (30min) and final interview with the CTO (1h) in person, on-site meetings
• Reference check & offer
• It can start as soon as you can!
