Langfuse - Senior Cloud Infra Engineer

📋 Job Overview

Your work will keep Langfuse running — everywhere. Langfuse processes over a billion trace events per month. When a Fortune 50 company relies on Langfuse in production, they're relying on the infrastructure you operate. You'll own uptime, performance, and cost efficiency across our entire cloud footprint — and you'll make sure every self-hosted deployment runs just as smoothly.

🏢 About Langfuse

Langfuse is now part of ClickHouse, which means the team behind the database at the core of our stack is one channel away. Few infrastructure roles give you that kind of direct access to the people who build your most critical dependency.

🎯 The Role

You will grow at Langfuse by owning Langfuse Cloud operations, building world-class observability, making self-hosting effortless, automating everything, scaling for what's next, and hardening security and compliance.

✅ Key Responsibilities

• Own Langfuse Cloud operations: Run our production environments on AWS ECS Fargate and ClickHouse Cloud.
• Build world-class observability: Own our Datadog setup end to end — dashboards, alerts, and SLOs.
• Make self-hosting effortless: Own and evolve our Helm chart, Docker Compose configuration, and deployment documentation.
• Automate everything: CI/CD pipelines, infrastructure-as-code, automated scaling, zero-downtime deployments.
• Scale for what's next: Think ahead about what breaks at 10x scale and build the foundation before we get there.
• Harden security and compliance: Ensure our cloud and self-hosted deployments meet the security and compliance bar that large organizations require.

📌 Required Qualifications

• Strong infrastructure or SRE engineer who gets excited about running systems at scale and making them better every day
• Experience operating production workloads on AWS (ECS/Fargate, networking, IAM, S3, etc.) or on comparable hyperscale vendors.
• 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 — you've built dashboards and alerts that actually caught problems (Datadog experience is a plus)
• You organize yourself. You have strong opinions about reliability, automation, and how to ship infrastructure changes safely
• Interest in open source software and genuine enjoyment helping users debug their self-hosted deployments
• Thrives in a small, accountable team where your output is visible and matters
• CS or quantitative degree preferred

⭐ Desirable Experience

• Experience with ClickHouse Cloud or other managed analytical databases
• Background in operating high-throughput event processing or observability infrastructure
• Contributions to open source infrastructure tooling (Helm charts, Terraform modules, etc.)
• Former founder
