Original job description

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.

We verify SQL, REST, native client APIs, authentication, authorization, RBAC, OAuth integrations, FIPS compatibility, and Linux, filesystem, networking, and process-level interfaces in the stack. You will be writing automated tests, running AI-assisted security scans, helping with scheduled CVE scans, and turning validated findings into reliable regression tests. Much of our software is open source and our tests make heavy use of open source software and development techniques. Your test code may be publicly visible, so it has to be great. You will be using AI daily but able to show your core technical skills without it.

Enjoy the flexibility of working from literally wherever and whenever. Create a schedule that works for you and your family or lifestyle. Recharge your batteries with our open vacation policies. Cultural Diversity: We love that we get to work with passionate people from around the world. Currently, our team is made of professionals from 25 different countries! Career Development: We provide opportunities to learn new technologies as well as try out new roles. We also offer access to training on leading-edge technologies, plus flexible work schedules for external education. USA Employees Benefits: We offer comprehensive PPO health care plans for our US-based employees that are incredibly flexible to meet the needs of individuals or families. 401K with company match also available. Company Travel: We come together in person two to three times per year in locations across the globe.
