We are looking for a Senior DevOps Engineer with strong cloud infrastructure expertise (GCP / AWS / Azure) using Terraform and deep MongoDB Atlas ownership experience to design, operate, and scale a cloud‑native infrastructure powering a large enterprise SaaS platform. This is a high‑ownership, architecture‑level role, not just execution. You will be responsible for designing and running production systems end‑to‑end, with a particular focus on database infrastructure (MongoDB Atlas) and scalable cloud environments. You will work in a fully remote, async‑first environment, collaborating closely with engineering teams to ensure high availability, performance, and operational excellence across multiple environments.
