In this role, you will drive performance and scalability improvements across the stack, taking on ambiguous, high-impact technical challenges most engineers never get to touch.

- Drive the performance roadmap for latency, throughput, memory efficiency and hardware utilization improvements
- Participate in the development of a complex, high-performance database system, including meticulous testing and safe production rollout
- Represent the company externally through presentations, blog posts, and community contributions
- Mentor and support junior engineers on the team
What You'll Bring
- 5+ years of experience in database performance engineering, distributed systems
- Master or PhD in databases or a related field
- Strong fluency in C++ and a background in performance-critical software or systems programming
- A track record of driving complex performance improvements end-to-end
