System Engineer

Key Responsibilities

• Improve speed, efficiency, quality, and reliability across core product workflows
• Profile and debug bottlenecks across application code, media workflows, data movement, and infrastructure boundaries
• Build benchmarking, regression tracking, and test harnesses for important system behavior
• Improve concurrency, caching, batching, scheduling, and resource usage
• Design internal interfaces that make complex technical systems easier for the rest of the product team to use
• Work close to product needs while making deep technical improvements under the hood

Required Qualifications

• Strong systems engineering fundamentals — you think naturally about latency, throughput, memory, CPU, GPU, I/O, and resource efficiency
• Experience improving production software where performance actually matters
• Proficiency in C++ or similar low-level languages, in addition to higher-level backend work
• Ability to measure before optimizing and explain tradeoffs concretely
• Good taste for building simple, clean abstractions around complex internals
• Comfortable using AI tools to move faster, while using personal judgment to define the problem and drive the solution
• Must be willing to work on-site in San Francisco, CA

Preferred Qualifications

• Background in robotics, embedded systems, or electronics engineering
• Comfort working below the obvious product surface when needed
• Track record of shipping specific, measurable performance improvements in production
