Who you are

• Sonio is a mission-driven company, so interest in our mission is critical. Other requirements are:
• 4+ years of experience in SRE, DevOps, or Production Engineering, including significant on-call experience on a 24/7 product
• You possess a hybrid "code-literate" mindset, acting as an infrastructure expert who can also navigate a backend codebase to triage and patch issues independently
• You bring strong technical foundations in Kubernetes, Terraform, and AWS, along with the ability to architect and tune your own observability signals
• You are highly autonomous and comfortable making technical decisions with limited supervision, which is essential given the timezone difference with France
• You maintain operational rigor and stay calm under pressure, with the written English skills necessary to produce high-quality runbooks and handle async handoffs

What the job involves

• As our first SRE & first engineer in the US, you will own the platform’s stability and releases, especially during PST hours
• You are the perfect "bridge" profile: part system administrator, part software engineer
• You don't just manage infrastructure; you understand the code running on it
• You will operate with high autonomy, making critical decisions during incidents and ensuring that our production environment is state-of-the-art, secure, and resilient
• You’ll report to our Lead DevOps Engineer, Pierre
• Own US coverage for releases and incidents as the first responder during PST hours
• Bridge infra and code by working hand-in-hand with our DevOps team on Kubernetes, Terraform, and AWS, while being able to read and patch Elixir code to unblock yourself without waiting for a backend engineer
• Drive incident response end-to-end, managing triage, mitigation, and blameless post-mortems with real follow-through
• Improve the platform’s operability by defining SLOs, tuning alerts to reduce toil, and pushing observability (metrics, logs, tracing) where it’s lacking
• Transfer operational knowledge from France to the US by authoring runbooks and documenting procedures so local teams are empowered to act when something breaks
• Support compliance and security in our regulated medical-device environment, maintaining HIPAA-aligned controls and an audit-ready infrastructure
