Platform Support Engineer (Singapore)

About the role

Braintrust is an agent observability platform used by companies such as Notion, Stripe, Box, OpenAI and Cloudflare to trace agents, find issues in their observability data and run evals. Its largest customers run the stack in their own AWS, Azure and GCP accounts behind their own VPCs, and Platform Support is the technical front line for infrastructure, performance and reliability. Braintrust is hiring Platform Support Engineers at mid and senior levels to join a small, high-ownership team working closely with Cloud Infrastructure and Engineering teams.

Key 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 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.
• Lead incident response: triage, communicate clearly while the issue is active, and drive it to resolution.
• Ship fixes by submitting PRs to backend services, Terraform modules and deployment tooling.
• Build diagnostics, health checks, preflight validation and self-service paths that help customers unblock themselves.
• Write and maintain runbooks and deployment documentation, and feed failure patterns back to Engineering and Product.
• Participate in an on-call rotation for critical customer issues.

Required profile

• Experience in a customer-facing technical role (Support Engineering, SRE, DevOps, Solutions Architecture, Infrastructure Engineering) or backend/infrastructure engineering with a real appetite for customer work.
• Strong Kubernetes fundamentals: deploying, debugging and scaling workloads, reading events and logs.
• Hands-on Terraform and depth in at least one major cloud (AWS strongly preferred).
• Fluency with observability tooling and comfort in a backend codebase (Python, TypeScript or Go) to reproduce and fix bugs.
• Clear, calm communication under pressure and ownership of problems until the customer is running again.

What we offer

• Medical, dental and vision insurance.
• Daily lunch, snacks and beverages.
