Singapore CLICKHOUSE PTE. LTD. Full time
With over 40,000 stars on GitHub, ClickHouse is the fastest and most resource efficient open-source data warehouse in the world. Our Core Engineering teams own the heart of our ClickHouse Open Source project. We are looking for exceptional C++ engineers to join our remote-first, global team and continue to scale and grow both our open source and ClickHouse Cloud offerings. More specifically, we are seeking engineers who love scaling and optimizing the performance of highly distributed systems.
What will you do?
  • As part of the ClickHouse Core teams, you will contribute to, analyze, and optimize the performance of the core ClickHouse database. The team works on many different topics such as query optimization, distributed query optimization, relational operators (e.g. aggregation and joins), caching, and low-level optimizations like SIMD instructions.
  • You will ensure that the database performance does not deteriorate over time by extending existing and adding new performance tests, based on real-world or synthetic datasets.
  • You will serve as a resource for the Support Engineering team, helping to debug the most advanced performance issues encountered by our customers. This includes an on call rotation as well as participation in our external community support channels.
  • As the core ClickHouse database continues to move at a fast pace, you will closely collaborate with our other teams to assess the impact of new features on performance and reliability
  • You will work with our open-source community. This will include resolving issues, reviewing and finishing PRs, answering questions from mail, chats, google groups, external Slack channels, etc.
About you:
  • You bring along solid professional software development experience in C++. This includes experience with Unix Systems.
  • You have strong knowledge in database internals and design.
  • You have experience in performance engineering, ideally in a database but other areas like high-frequency trading, simulation, real time data processing etc. are also okay.
  • You communicate well with others and have the ability to work well within and across engineering teams.
  • You are ready to work closely with our open-source community. You participate in code reviews with patience and attention to detail fostering a culture of collaboration and mutual respect.
  • You are a strong problem-solver and have solid production debugging skills.
  • You are passionate about efficiency, availability, scalability and data governance.
  • You thrive in a fast-paced start-up environment, seeing yourself as a partner with the business with the shared goal of moving forward and building together.
  • You have a high level of responsibility, ownership, and accountability.
Bonus points for:
  • Experience with ClickHouse.
  • Experience in security, privacy, and compliance.
  • Experience with TCP/IP and network programming.
  • Experience developing cloud infrastructure services, preferably with Kubernetes.
  • Experience giving public talks at technical conferences and meetups.
  • Previous contributions to open source projects.
