About the company

S3NS was born from the industrial partnership between Thales, a global leader in cybersecurity, and Google Cloud, a global leader in cloud solutions. Our ambition is to offer the best of both worlds to all organizations concerned with protecting their sensitive data (public institutions, OIV, OSE...). That is to say, a solution equivalent to Google Cloud Platform (including both GCP IaaS and PaaS services) and respecting the requirements of the SecNumCloud label.

Your tasks

A first offering, 'Local Controls with S3NS', has already been available since February 2023 to allow our customers to benefit from a first level of transparency and additional controls, and to accelerate the trajectory towards a trusted cloud.

You will be responsible for the operational maintenance, operation, and management of all Compute platforms (GCE, GKE, Vertex AI...), within an environment equivalent to the GCP universe. Thanks to our privileged partnership, Google shares its knowledge with us and opens the doors to its internal technical stack, as well as offering certified Google public training.

  • Incident Diagnosis and Resolution: In order to ensure 24/7 operational maintenance of our cloud, the position involves daytime shifts as well as rotating night on-call duties.
  • Team Collaboration: Collaborate with technical leads from different compute services to help resolve incidents.
  • Automation & Knowledge: Document knowledge to ensure that all S3NS SREs work with the same information, standardize resolution workflows, and improve operational playbooks.
  • Post-incident Reviews: After an incident, bring teams together to perform a post-mortem, understand the causes, draw lessons, and encourage continuous improvement.

Requirements

You have at least a 2-year degree (bac+2) with a first experience in MCO within Linux production environments and operations automation. You must have operational English, given the interactions with our counterparts at Google.
