Your mission extends beyond building a rock-solid foundation for autonomous driving — you will also equip engineers with the tools needed to analyze system behavior, identify performance bottlenecks, and enhance robustness. In this role, you will contribute to existing frameworks, libraries, and tools while also designing and implementing new components across various mission-critical domains. Responsibilities: - Design and optimize low-latency interprocess communication and data flow monitoring. - Develop high-performance event logging and structured telemetry. - Implement safety-enhanced memory allocators and efficient memory provisioning policies. - Build lock-free data structures and algorithms to support real-time system requirements. - Work on network communication and coherency protocols. - Develop on-the-fly component health monitoring and rapid response mechanisms for critical events. - Manage on-vehicle configurations and system state validation. - Optimize low-level OS interactions and fine-tune system performance. - Ensure that your work is performed in accordance with the company’s Quality Management System (QMS) requirements and contribute to continuous improvement efforts. - Ensure team compliance with QMS, monitor quality, and drive process improvements. Required Skills: - BS in Computer Science, Electrical Engineering, or related field. - Solid hands-on coding experience using C++14(or later) - Strong understanding of Linux development tools, including build systems, compilers, debuggers, and performance analyzers. - Excellent written and verbal communication skills. - Proactive problem-solving mindset: ability to identify, propose, and implement solutions. Preferred Skills: - Experience in writing, debugging, and profiling multithreaded C++ applications. - Familiarity with robotics-related libraries such as ROS. - Knowledge of real-time OS, database internals, network programming, GPGPU, or robotics. Salary Range: - $120,000 - $200,000 a year Our compensations (cash and equity) are determined based on the position, your location, qualifications, and experience. ## About PlusAI ## Company Overview - **One-liner**: PlusAI develops AI-based autonomous driving software for heavy trucks, powering Level 4 (L4) virtual driver systems that enable trucks to operate without human intervention on highways. - **Entity Type**: Private (planning to go public via a SPAC merger with Churchill Capital Corp IX, NYSE: PLAV – conflicting reports indicate the reverse merger may have been cancelled) - **Headquarters**: Santa Clara, California, United States - **Founded**: 2016 - **Founders**: Not publicly available in provided sources ## Core Business - **Primary industry**: Autonomous driving / automotive technology - **Target customers**: B2B – global truck manufacturers (OEMs) and large freight fleets - **Mission**: To make trucking safer, more efficient, and more sustainable by deploying AI-powered autonomous driving at scale ## Products & Services - **SuperDrive**: L4 autonomous driving system that serves as a virtual driver for factory-built heavy trucks. Designed to be installed by OEMs and monetized on a per-mile usage basis. - **PlusDrive**: A driver-assist version of SuperDrive that keeps a human in the cabin to oversee the system. Already in commercial use, reducing driver fatigue and fuel costs. - **SuperDrive HyperFoundry**: A suite of proprietary AV data and tools (data acquisition, auto-labeling, 3D reconstruction, neural simulation) sold to third-party customers today, generating revenue before the full L4 launch. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed; the SPAC merger was valued at $300M (conflicting reports of cancellation). - **Key Metric**: Annual revenue of $4M (as of latest data); total funding of ~$1.3B across 8 rounds. - **Notable Investors/Partners**: TRATON GROUP (Scania, MAN, International), Hyundai Motor Company, Iveco Group, Bosch, DSV, Ryder. - **Growth Signals**: - Active trial with Ryder and International on a 600+ mile daily route (I-35 corridor) – 60,000+ cumulative miles, approaching 100 runs. - Recent software upgrades enabling night driving and construction zone capabilities. - Partnered with multiple global OEMs to install SuperDrive on factory-built trucks – no retrofitting required. - 7M+ miles of L4-validated data collected. ## Competitive Advantages - **Asset-light software model**: Zero manufacturing capex – PlusAI is a pure-play software provider, avoiding heavy hardware costs. - **OEM integration**: Factory-installed by partners like TRATON and Hyundai, providing a scalable path to thousands of trucks. - **Proprietary data moat**: Over $500M in R&D investment and 7M+ miles of validated data enable advanced AI models (end-to-end and vision-language-action). - **Capital efficiency**: Path to cash-flow positive in 2027E, with lower OpEx than key competitors. ## Strategic Focus - **Near-term**: Commercial launch of driverless L4 trucks in 2027, targeting revenue from per-mile usage. - **Current revenue generation**: Selling AV data and tools (HyperFoundry) to third parties. - **R&D edge**: Leveraging large AI models and generative AI to continuously improve the virtual driver’s capabilities and expand the Operational Design Domain (ODD). ## Why Work Here - **Culture & ratings**: Employer rating of 4.1/5 (30 reviews), with high marks for work-life balance (4.6), culture (4.7), and career growth (4.6). - **Engineering focus**: 105 technical employees (23% of workforce); active job postings (38) include senior ML infrastructure, perception, planning, simulation, and engineering intern roles. - **Global offices**: HQ in Santa Clara, CA, with offices in Fremont, Cupertino, and Munich, Germany. Workforce spans 8 countries. - **Notable perks**: Opportunity to work on cutting-edge autonomous driving technology with partners like TRATON, Hyundai, and Bosch. Strong talent pipeline from Stanford, CMU, and alumni at Waymo, NVIDIA, Apple. ## Sources 1. [LinkedIn – PlusAI](https://linkedin.com/company/plusai) 2.
