About the role

Key responsibilities & impact

Own latency, throughput, memory utilization, and thread safety for the real-time decision-making pipeline.
Instrument the behavior pipeline to measure runtime performance, isolating latency spikes, resource contention, and memory inefficiencies.
Refactor high-frequency execution loops to maximize cache utilization, eliminate dynamic memory allocations, and reduce tail latency.
Re-engineer thread boundaries and synchronization logic to maximize multi-core parallel processing while ensuring thread safety.
Build automated micro-benchmarks and runtime telemetry into CI/CD pipelines to prevent performance regressions.
Partner with autonomy teams to establish performant, low-overhead C++ module interfaces for new behavioral features.

Requirements

What you’ll need

Deep understanding of CPU cache hierarchies (L1/L2/L3), memory alignment, lock-free concurrency models, and Linux OS thread scheduling.
Hands-on experience with Linux profiling toolchains (e.g., Perf, Tracy, eBPF) and dynamic sanitizers (ASan, TSan, Valgrind).
Strong proficiency in modern C++ (C++17/20) with a focus on writing low-overhead abstractions, RAII, and cache-friendly data layouts.
Familiarity with micro-benchmarking frameworks (e.g., Google Benchmark) and performance-regression testing in continuous integration.
Experience in performance-critical software environments such as game engines, financial technology, database runtimes, or operating system kernels.
B.S. Degree in Computer Science, Computer Engineering, or an equivalent degree.
Master’s degree or PhD in Computer Science, Computer Engineering, or a related field is desirable.
At least 5 years of professional experience is desirable.
Prior experience in AV, robotics, or high-throughput real-time control systems is desirable.
Proven track record of designing and scaling automated CI/CD performance testing infrastructure is desirable.
