Staff Software Engineer, Software Systems

Staff Software Engineer, Software SystemsBrain Corp is the global leader in robotic AI software that powers the largest fleet of autonomous mobile robots (AMRs) operating in commercial public spaces. Global OEM partners use our cloud-connected platform, BrainOS®, to create scalable, self-driving robots that are used by end customers to clean floors, move inventory and sense environmental data - turning manual operations into automated workflows.Position Overview:The Staff Software Engineer is a key technical leader within Brain Corp's Platform team, responsible for the architecture, evolution, and performance of core software systems powering our autonomous mobile robots (AMRs). This includes ownership of the Hardware Abstraction Layer (HAL), telemetry systems, and core C++ middleware.This role is highly hands-on and strategic, driving the re-architecture of foundational robotics software to improve modularity, scalability, and performance. The engineer will lead technical direction across HAL and middleware layers, enabling efficient sensor integration, new hardware bring-up, and high-performance execution on embedded systems. Working cross-functionally with hardware, autonomy and applications teams, this role will ensure that our robotics platform supports rapid innovation, robust field performance, and scalable deployment across a global fleet.Essential Job Functions:Lead the technical direction and architecture of the Hardware Abstraction Layer (HAL), ensuring modularity, scalability, and long-term maintainabilityDrive the migration and re-architecture of HAL to support next-generation robotics platforms and evolving hardware requirementsOwn the design and evolution of the robotics telemetry and replay systems, improving observability, reliability, and data qualityLead the migration of middleware components from Python to high-performance C++ implementationsArchitect and develop robust C++ middleware enabling efficient communication between sensors, compute, and autonomy systemsIntegrate and bring up new hardware components, including sensors such as LiDARs, cameras, and IMUsOptimize system performance across the robotics stack, including latency, throughput, memory usage, and CPU efficiencyCollaborate closely with hardware, apps, autonomy, and QA teams to ensure seamless system integration and deploymentEstablish and enforce best practices in software design, code quality, testing, and documentationProvide technical mentorship and leadership to engineers, guiding design reviews and complex debugging effortsContribute hands-on code to critical components while balancing long-term architectural improvementsDrive continuous improvement of development workflows, testing strategies, and system reliabilityEducation and/or Work Experience Requirements:Bachelor's or Master's Degree in Computer Science, Software Engineering, Robotics, or a related technical field7+ years of professional software engineering experienceProven experience working on robotics systems, embedded platforms, or hardware abstraction layers (HAL)Demonstrated experience leading complex technical initiatives or driving architectural changes in production systemsRequired Knowledge, Skills, Abilities and Other Characteristics:Expert-level proficiency in modern C++ (C++11 or later), including multithreading, memory management, and performance optimizationStrong Python skills for scripting, tooling, and system integrationDeep understanding of hardware abstraction layers and low-level system designHands-on experience integrating sensors such as LiDARs, cameras, and IMUs into production systemsStrong experience with Linux-based development environments (e.g., Ubuntu)Experience designing and developing middleware systems or inter-process communication frameworksFamiliarity with communication protocols such as MQTT, or similar paradigmsExperience with build systems (e.g., CMake) and unit testing frameworks (e.g., Google Test)Proven ability to design scalable, maintainable, and modular system architecturesStrong debugging and troubleshooting skills in complex robotics or embedded environmentsExperience with system performance profiling and optimization (CPU, memory, latency, throughput)Proficiency with version control systems such as GitExcellent communication skills and ability to provide technical leadership and mentorship without direct management responsibilityThings that Make a Difference:Experience with Autonomous Mobile Robots (AMRs) or similar robotic systemsPrior experience leading or contributing to large-scale system re-architecture or migration effortsExperience designing or improving telemetry and observability systemsFamiliarity with custom middleware architectures (non-ROS environments)Background in real-time or near-real-time systemsExperience working at the intersection of hardware and software integrationPassion for robotics, automation, and building high-performance, scalable systemsPhysical Demands:The physical demands described here are representative of those that must be met by an employee to successfully perform the essential functions of this job.
