About the role
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, and your main mission will be: Own US coverage for releases and incidents as the first responder. 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. About the profile 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. Location : Boston Salary : $165,000 -190,000 + 10% bonus
