Database Engineer
at Next gen BI platform for data driven performance marketers
This leads to a very interesting and challenging use case in the emerging field of large scale distributed HTAP, which is still not mature enough to provide a solution out of the box that works for our scale and SLAs. So, we are building a solution that can handle the complexity of our use case and scale to several trillions of rows. As a "Database Engineer", you will evolve, architect, build and scale the core data warehouse that sits at the heart of Clarisights enabling large scale distributed, interactive analytics on near realtime data.
What you'll do
- Understanding and gaining expertise in existing data warehouse.
- Use the above knowledge to identify gaps in the current system and formulate strategies around what can be done to fill them
- Avail KPIs around the data warehouse.
- Find solutions to evolve and scale the data warehouse. This will involve a lot of technical research, benchmarking and testing of existing and candidate replacement systems.
- Bulid from scratch all or parts of the data warehouse to improve the KPIs.
- Ensure the SLAs and SLOs of data warehouse, which will require assuming ownership and being oncall for the same.
- Gain deep understanding into Linux and understand concepts that drive performance characteristics like IO scheduling, paging, processing scheduling, CPU instruction pipelining etc.
- Adopt/build tooling and tune the systems to extract maximum performance out of the underlying hardware.
- Build wrappers/microservices for improving visibility, control, adoption and ease of use for the data warehouse.
- Build tooling and automation for monitoring, debugging and deployment of the warehouse.
- Contribute to open source database technologies that are used at or are potential candidates for use.
What you bring
We are looking for engineers with a strong passion for solving challenging engineering problems and a burning desire to learn and grow in a fast growing startup. This is not an easy gig, it will require strong technical chops and an insatiable curiosity to make things better. We need passionate and mature engineers who can do wonders with some mentoring and don't need to be managed.
