What we are looking for
- Very experienced software engineer with a focus on high-performance computing.
- Familiarity with optimization techniques such as reducing memory allocations, SIMD, optimizing for CPU cache locality, and other low-level concepts.
- Experience with Go or willingness to learn the intricacies of high-performance Golang. If you are unfamiliar with Go, it’s important to have experience with C/C++ or Rust or a comparable language.
- Familiarity with or willingness to learn Approximate nearest neighbor algorithms, such as HNSW, Vamana, Product Quantization (PQ), and others.
- Strong skills in algorithmic reasoning, probability, statistics, or Machine Learning.
- Great understanding of how databases work under the hood and are familiar with concepts such as B-Trees, LSM Stores, and various indexes.
- Quick learner, excited to dive into new topics.
- You are aligned with our company values.
What we offer
- 100% remote with flexible work hours.
- Competitive compensation, including paid time off.
- Budget available to spend on going to conferences, co-working space, home office equipment, etc.
- Work with very experienced and fun team members.
