Senior Software Engineer Performance

Remote · Full Time

About this role

Weaviate is a low-latency, large-scale vector database. As such, any code that lands on the hot path has the potential to be very optimized. Weaviate’s users care about low latency and high throughput. In addition, reducing the build times for our vector indices makes our users happy. Similarly, you are passionate about eliminating heap allocations when a stack allocation would have been more efficient. You like writing code that is friendly to CPU caches without sacrificing readability, reliability, and ease of use. You are not discouraged by the limitations of programming languages, but rather see those as opportunities to push boundaries and become creative. You are used to working in a metrics-driven fashion and measuring performance improvements. In addition to making Weaviate perform better and reduce operating costs, you will help the entire team to set up benchmarks, make performance part of continuous integration and work in a performance-first manner.

What we are looking for

  • You have experience with working on performance-critical code
  • You enjoy working on low-level optimizations
  • You have strong experience with Golang and a great understanding of how memory management works in Golang.
  • Alternatively, you have strong experience in C/C++/Rust and are convinced that this will translate to Golang
  • You are passionate about diving into new algorithms, such as ANN algorithms for vector similarity search and engineering them in a performant fashion
  • You are a great communicator and team player

What we offer

  • 100% remote with flexible work hours.
  • Competitive compensation, including paid time off.
  • You will work at the forefront of search, ML/AI, and cloud-native technologies - and all of it is open source.
  • An atmosphere that encourages learning and personal growth, with very experienced team members to learn from.
  • Opportunities to speak at conferences, publish blog posts, videos, etc. (We are aware that this is not for everyone and is therefore optional).
