Based on patented algorithms and a proprietary expert database Sonio aims to become the reference tool to help practitioners improve screening reduce diagnostic errors and optimize pregnant womens medical path.

About the role

As our first SRE & first engineer in the US you will own the platforms stability and releases especially during PST hours.

You are the perfect bridge profile: part system administrator part software engineer. You dont 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.

Youll 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 platforms operability by defining SLOs tuning alerts to reduce toil and pushing observability (metrics logs tracing) where its 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.
