Job summary

Langfuse is expanding its cloud infrastructure team to keep the platform reliable at scale across cloud and self-hosted deployments. You will own production environments on AWS ECS Fargate and ClickHouse Cloud, drive autoscaling, capacity planning, and cost optimization while maintaining superb observability with Datadog.

We value engineers who ship reliable infrastructure, automate CI/CD and IaC, and can evolve Helm charts and deployment docs for diverse customers from startups to enterprises.

Qualifications

• Strong infrastructure or SRE engineer with experience running systems at scale.
• Experience operating production workloads on AWS (ECS/Fargate, networking, IAM, S3) or comparable hyperscale environments.
• Comfortable with container orchestration — Kubernetes and/or ECS, Helm charts, Docker.
• Experience with infrastructure-as-code (Terraform, Pulumi, CloudFormation, or similar).
• Strong monitoring and observability instincts — dashboards and alerts that catch problems; Datadog a plus.
• Organized with strong opinions about reliability, automation, and safe infrastructure changes.
• Interest in open source software and helping users debug self-hosted deployments.
• Thrives in a small, accountable team where output is visible and impactful.

Responsibilities

• Own Langfuse Cloud operations: production environments on AWS ECS Fargate and ClickHouse Cloud, manage deployments, autoscaling, capacity planning and cost optimization.
• Build world-class observability: own Datadog end-to-end—dashboards, alerts, and SLOs to pre-empt issues.
• Make self-hosting effortless: own Helm chart, Docker Compose, and deployment docs for single-node to multi-region deployments.
• Automate everything: CI/CD pipelines, infrastructure-as-code, and zero-downtime deployments.
• Scale for what's next: anticipate issues at 10x scale and build robust foundations.
• Harden security and compliance: ensure deployments meet security/compliance standards for enterprises.
