About the role

Platform Support Engineers own customer-facing support for hybrid and self-hosted Braintrust deployments across AWS, Azure, and GCP, from first install through steady-state operation. They debug infrastructure problems, diagnose backend performance issues, lead incident response, ship fixes, build diagnostics tooling, maintain runbooks, feed patterns back to Engineering, and participate in on-call rotations.

Responsibilities

  • Own customer-facing support for hybrid and self-hosted Braintrust deployments across AWS, Azure, and GCP — from first install through steady-state operation.
  • Debug real infrastructure problems: Kubernetes workloads, Terraform state, networking and VPC configuration, IAM and permissions, TLS, and cloud-provider quirks.
  • Diagnose performance and reliability issues in the backend — ingest throughput, query latency, database and object-store behavior — using logs, metrics, and traces to get to cause rather than symptom.
  • Lead incident response for customer-impacting issues: triage, communicate clearly while it's still on fire, and drive it to resolution.
  • Ship fixes. Submit PRs to our backend services, Terraform modules, and deployment tooling rather than handing every problem to Engineering.
  • Build the tooling that makes the next one easier — diagnostics, health checks, preflight validation, and self-service paths that let customers unblock themselves.
  • Write and maintain the runbooks and deployment documentation that turn one hard-won answer into a permanent one.
  • Feed patterns back to Engineering and Product, so the recurring failure modes stop recurring.
  • Participate in an on-call rotation for critical customer issues.

Qualifications

  • Experience in a customer-facing technical role — Support Engineering, SRE, DevOps, Solutions Architecture, or Infrastructure Engineering — or backend/infra engineering experience with real appetite for customer work.
  • Strong Kubernetes fundamentals: you can deploy, debug, and scale actual workloads, and read a failing pod's story from its events and logs.
  • Hands-on Terraform, and depth in at least one major cloud (AWS strongly preferred).
  • Comfort in a backend codebase — Python, TypeScript, or Go — enough to reproduce a bug, trace it to its source, and fix it.
  • Fluency with observability tooling, and the instinct to reach for data before opinion.
  • Clear, calm, direct communication under pressure, especially when the customer is technical, blocked, and losing time.
  • Ownership. You take a problem personally and follow it until the customer is running again.
