*ClickHouse Open-Source Database Developer (C++, DB internals)

ClickHouse is the hottest analytic database on the planet and Altinity is the home of ClickHouse experts who build real-time data solutions that run anywhere. ClickHouse now has more contributors than ElasticSearch, previously the biggest open-source analytic project on GitHub.

Altinity is looking for a great server internals engineer to work on contributions to ClickHouse. As Open-Source Database Developer you’ll be responsible for designing, implementing, and supporting features of ClickHouse ranging from encryption to storage to query processing. We’re looking for imaginative engineers with a background in database internals and in high-performance languages like C++.

We have lots of exciting projects underway as we help the community adapt ClickHouse to the cloud and Kubernetes.

Our ideal candidate has:

• Proven experience in design, implementation, and testing high-performance DBMS features in a complex C++ codebase.
• Excellent background in database internals including query languages, access methods, storage, and/or connectivity
• Demonstrated ability to read and write good C++
• Good understanding of networking and I/O on Linux
• Familiar with performance optimization techniques and tools
• History of getting pull requests vetted and merged in rapidly evolving open-source projects
• Sound knowledge of database testing, debugging, and low-level performance optimization
• Enthusiasm to learn more about database technology and data-related applications
• Good English language reading and writing skills
• Eager to work with a friendly, distributed team following open-source dev practices
• MAJOR PLUS: previous development experience on ClickHouse

A day in your life as a ClickHouse server engineer may include any or all of the following:

• Write good task-specific C++ code and solidify it with tests
• Debug issues reported by users, fix them and add tests to make sure they wouldn’t happen again
• Profile existing code and make it faster (either by applying clever algorithms, adding vectorized intrinsics or by implementing cool tricks), add performance tests
• Submit your own pull requests and review pull requests from others
• Help the Support Team to investigate customer problems running ClickHouse
• Help new community members contribute to ClickHouse
• Attend meetups and make presentations on open-source development
• Write blog articles and share information about ClickHouse
