About ClickHouse

Recognized on the 2025 Forbes Cloud 100 list, ClickHouse is one of the most innovative and fast-growing private cloud companies. With more than 3,000 customers and ARR that has grown over 250 percent year over year, ClickHouse leads the market in real-time analytics, data warehousing, observability, and AI workloads.

The company's sustained, accelerating momentum was recently validated by a $400M Series D financing round. Over the past three months, customers including Capital One, Lovable, Decagon, Polymarket, and Airwallex have adopted the platform or expanded existing deployments. These customers join an established base of AI innovators and global brands such as Meta, Cursor, Sony, and Tesla.

We're on a mission to transform how companies use data. Come be a part of our journey!

About the Role

ClickHouse is launching a strategic Postgres initiative to extend our developer-first cloud platform, so teams can easily integrate Postgres with ClickHouse and power end-to-end data workflows.

We're looking for a Senior Software Engineer to join the team building this platform. You'll work across a range of areas — from control plane services and automation to operational tooling and developer experience. This is a flexible, full-stack systems role for an engineer who thrives in environments where boundaries are fluid, problems are complex, and impact is tangible.

What You'll Do

Design and build backend services that orchestrate and manage database clusters in ClickHouse Cloud.
Extend our platform control plane — written in Ruby, Go, and TypeScript — to support new Postgres capabilities.
Contribute to PostgreSQL extensions and data plane agents, written in C, C++ or Rust
Contribute to automation and tooling that simplify cluster provisioning, scaling, and lifecycle management.
Collaborate with infrastructure, SRE, and product teams to ensure operational excellence, performance, and reliability.
Develop APIs and integrations that expose new Postgres functionality to customers and internal systems.
Improve observability, deployment safety, and debugging workflows for database services.
Participate in design discussions, code reviews, and on-call rotations, contributing to the overall reliability and velocity of the team.
Operate with autonomy — identifying opportunities, driving execution, and delivering meaningful impact.

About You

Experience: 6+ years in software engineering, ideally with experience building or operating database or cloud platform systems.
Postgres Expertise: Deep understanding of Postgres — configuration, extensions, operations, and performance tuning.
Technical Skills:
- Strong programming experience in one or several of Ruby, Go, Rust, C or Python (and willingness to work across languages).
- Familiarity with cloud infrastructure, APIs, and automation tools (Terraform, Kubernetes, CI/CD).
- Understanding of distributed systems, data replication, and service orchestration patterns.
Mindset: Pragmatic, detail-oriented, and comfortable with both greenfield development and operational ownership.
Flexibility: Happy to contribute where needed — from backend APIs and platform automation to Postgres internals and debugging.
Collaboration: Strong communicator who works effectively across teams in a fast-paced, cross-functional environment.
Ownership: You operate with a founder's mindset — take initiative, move quickly, and care deeply about outcomes.

Why Join Us

Be part of a strategic new offering that expands the scope and impact of ClickHouse Cloud.
Work with cutting-edge database and infrastructure technologies at scale.
Operate with high autonomy in a small, focused team that values deep expertise and collaboration.
Shape foundational systems for reliability, automation, and developer experience in managed database.
