Automate, manage, and optimize large-scale ClickHouse clusters handling trillions of events and 100+ PB data. Build provisioning systems with Terraform, Ansible, Kubernetes; focus on performance, scaling, and bleeding-edge features.
ClickHouse is the core piece of infrastructure at PostHog. Every product and customer relies on it to ingest, store, and query data.
We need someone to automate, manage, and maintain ClickHouse as we grow towards capturing trillions of events per year and having one of the world’s largest clusters.
This includes ClickHouse operations and scaling infrastructure, as well as node and instance-level performance optimization. Ensure the right hardware deployed at the right time for each workload on ClickHouse.
Build systems and automations for provisioning and scaling of large ClickHouse clusters, handling over 100 PB's of data. Investigate and experiment using the latest hardware that cloud providers have to offer. Use Terraform, Ansible, and Kubernetes to automate dynamic provisioning of instances and work on bleeding edge ClickHouse implementation, like open format backed tables, and query performance tooling.
Build platform primitives for service provisioning, deploy tooling, workflow orchestration, and service ownership at a fast-scaling AI coding tool company. Requires experience with durable workflows like Temporal, internal dev platforms, and strong focus on developer experience and reliability.
Build and operate AWS cloud and LLM infrastructure powering RAG, inference, and data pipelines for an aviation AI platform. Requires strong AWS depth, Python data pipelines, and production LLM experience.
Design, build, and operate scalable distributed systems and edge networks on AWS to handle Figma's growing customer traffic and services. Requires 4+ years building infrastructure at scale, experience with TypeScript or Go, and distributed/traffic systems.
Design, build, and operate petabyte-scale distributed systems for product metrics using Golang, Kubernetes, and ClickHouse. Requires 5+ years building scalable systems and 2+ years with Golang.
