## Job Description

## Responsibilities
- Analyze and optimize performance across application, middleware, runtime, and infrastructure layers—networking, storage, Python runtime, GPU utilization, and beyond.
- Develop tooling and metrics that provide deep observability into system performance.
- Collaborate closely with infra, platform, training, and product teams to identify key performance goals and drive systemic improvements.
- Influence architecture and design decisions to prioritize latency, throughput, and efficiency at scale.
- Lead investigations into high-impact performance regressions or scalability issues in production.
- Drive performance testing strategies and help define SLAs/SLOs around latency and throughput for critical systems.

## Requirements
- 7+ years of experience in software engineering with a strong track record in performance or reliability of high-scale distributed systems.
- Deeply comfortable with performance profiling tools and tracing systems.
- Experience optimizing performance across one or more layers of the stack (e.g., database, networking, storage, application runtime, GC tuning, Python/Golang internals, GPU utilization).
- Strong understanding of OS internals, scheduling, memory management, and IO patterns.
- Contributed to observability, benchmarking, or performance-focused infrastructure at scale.
- Demonstrated success navigating ambiguity and aligning stakeholders around performance goals.
- Value simplicity, rigor, and collaboration when solving complex systems problems.
