[Hiring] Senior Cloud Infra Engineer @ClickHouse

Role Description

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.

• Operate Langfuse Cloud on AWS ECS Fargate and ClickHouse Cloud, with Datadog as the observability backbone.
• Own our public self-hosted infrastructure — including our Helm chart, Docker Compose setup, and everything in between.
• Ensure the infrastructure grows ahead of demand as we scale fast.
• Direct access to the team behind the database at the core of our stack.

You will grow at Langfuse by:

• Owning Langfuse Cloud operations: Run our production environments on AWS ECS Fargate and ClickHouse Cloud, managing deployments, autoscaling, capacity planning, and cost optimization.
• Building world-class observability: Own our Datadog setup end to end — dashboards, alerts, and SLOs.
• Making self-hosting effortless: Own and evolve our Helm chart, Docker Compose configuration, and deployment documentation.
• Automating everything: Replace manual processes with automation that makes the team faster and the platform more reliable.
• Scaling for what's next: Think ahead about what breaks at 10x scale and build the foundation before we get there.
• Hardening security and compliance: Ensure our cloud and self-hosted deployments meet the security and compliance bar required by large organizations.

Qualifications

• 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 — experience building dashboards and alerts (Datadog experience is a plus).
• Organized with strong opinions about reliability, automation, and safe infrastructure changes.
• Interest in open source software and 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.

Requirements

• Bonus points for 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.

Benefits

• Employer contributions towards your healthcare.
• Equity in the company — stock options for every new team member.
• Flexible time off in the US, generous entitlement in other countries.
