Senior Software Engineer

Role Overview

Join ClickHouse as a Senior Software Engineer specializing in Python and the Data Ecosystem. You will be a core contributor to ClickHouse’s data engineering ecosystem, building tools and integrations that help Data Engineers and Data Scientists use ClickHouse’s speed and scale.

Key Missions

• Evolve ClickHouse’s critical data engineering ecosystem parts, especially Python integrations.
• Own and improve the ClickHouse Python connector and SDK ecosystem, focusing on performance, reliability, and API design.
• Design connectors/models that make ClickHouse a natural choice for:
  • RAG architectures
  • ML feature pipelines
  • LLM-powered data applications

Responsibilities

• Own the full lifecycle of key Python integrations.
• Drive the AI/LLM integration strategy.
• Collaborate with multiple teams to align integration work with platform priorities.
• Engage with the open-source community.

Requirements

• Hands-on AI/ML experience in data engineering contexts (e.g., embeddings generation, vector search, feature pipelines, or LLM tooling in production).
• 7+ years of software development experience; preferably hands-on as a Data Engineer, Data Scientist, or ML Engineer.
• Strong concurrent Python skills: threading, multiprocessing, and async patterns.
• Strong Python data ecosystem experience: Pandas, NumPy, Pydantic, and related libraries.
• Experience with data orchestration tools: Airflow, Dagster, or Prefect.
• Proven experience designing, building, and maintaining production-grade Python connectors/SDKs/integrations for at least one major platform.
• Solid database fundamentals: SQL, data modeling, query optimization, and familiarity with OLAP/analytical databases.
• Excellent written and verbal communication; comfortable collaborating across engineering functions and with open-source communities.
• Experience deploying AI/ML models in production (e.g., inference APIs and vector databases).
• Experience as a Data Engineer or Data Scientist in a product-facing or platform role.

Nice to Have

• Familiarity with the JVM ecosystem.
• Familiarity with ClickHouse or similar high-performance OLAP platforms.
