Responsibilities
Design and implement low-latency, high-throughput systems in modern C++ for resource-constrained hardware
Own and maintain real-time infrastructure including sensor fusion pipelines, motor control interfaces, deterministic schedulers, and shared foundational libraries
Develop and optimize IPC and serialization layers such as lock-free queues, memory pools, and shared-memory buffers to connect perception, planning, and actuation
Establish performance baselines using microbenchmarks, flamegraphs, performance counters, and regression tracking to ensure consistency under load
Debug complex system-level issues including ABI mismatches, linking errors, kernel interfaces, and cross-compilation challenges
Build deterministic systems with clean failure modes and interfaces that enable reliable development by other engineering teams
Ship robust code that runs not just in prototypes, but across thousands of deployed robots in homes and warehouses
Qualification
Required
5+ years of experience developing production-grade C++ in performance-critical environments such as robotics, autonomous systems, game engines, compilers, or high-frequency trading
Deep understanding of system-level constraints including latency, memory usage, bandwidth, and startup time—and the ability to design within those constraints
Proficiency with Unix/Linux development environments, including shells, GNU tools, and system interfaces
Experience shipping real-time systems where software reliability directly impacts physical behavior
Strong debugging and profiling skills at the systems level, with expertise in benchmarking, tracing, and use of Linux kernel interfaces
Ability to write clean, maintainable, and high-performance code with clear interfaces and minimal dependencies
Benefits
Health, dental, and vision insurance
