THE OPPORTUNITY We are hiring a Staff Platform Engineer specialized in Observability for our Platform area in Brazil ! This is a Remote – Brazil position, meaning you can work from anywhere within the country. Please note that this role is only open to candidates in Brazil. Wellhub runs at high scale, on many Kubernetes clusters. Our engineers need logs, metrics, traces and profiles they can trust, at a cost the business can sustain.

Collection, storage, query and alerting that stay reliable when the company grows. We also watch the watchers: the platform must tell us when it is broken. Our stack includes Grafana, OpenTelemetry, Prometheus, Thanos, Loki, Tempo, Pyroscope, Kafka, Kubernetes, AWS, GitHub Actions, ArgoCD, Crossplane and HashiCorp Vault. You will write code in Go, Ruby or Python to build our tools. YOUR IMPACT Our team does not run services for other teams. We build tools and abstractions so each team can own and run its own services end to end. Your work will rest on four things: stability , performance , cost and evolution of the platform. In this role you will: Review our current platform with fresh eyes. Say what is wrong, propose better solutions, and help the team evolve them. Own our observability stack end to end. Keep it resilient, scalable and ready for growth. Evolve the Kubernetes-based infrastructure it runs on. Close the gap between complex infrastructure and developer experience. Build the abstractions that let teams manage their own observability. Set standards and guidelines, and write them down through RFCs. Work with the whole team day to day: pair on…
