## About the Role

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

## Description

As a Senior Performance Engineer on the Behavior Planning team, you will own latency, throughput, memory utilization, and thread safety for our real-time decision-making pipeline. Working alongside staff roboticists who write high-level autonomy logic, your job is to profile the stack, enforce performance budgets, and build execution guardrails that guarantee deterministic, high-throughput execution.
Prior background in autonomous vehicles, controls, or robotics math is not required. We are seeking engineers obsessed with system performance, low-level execution concepts, and software profiling tools.
Essential Responsibilities

 * System Diagnostics: Instrument the behavior pipeline to measure runtime performance, isolating latency spikes, resource contention, and memory inefficiencies.
 * Pipeline Optimization: Refactor high-frequency execution loops to maximize cache utilization, eliminate dynamic memory allocations, and reduce tail latency.
 * Concurrency Architecture: Re-engineer thread boundaries and synchronization logic to maximize multi-core parallel processing while ensuring thread safety.
 * Performance Guardrails: Build automated micro-benchmarks and runtime telemetry into CI/CD pipelines to prevent algorithm developers from introducing performance regressions.
 * API Design: Partner with autonomy teams to establish performant, low-overhead C++ module interfaces for new behavioral features.
