Senior DevOps & Site Reliability Engineer

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 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.
  

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.
