Headquartered in Silicon Valley with operations in the United States and Europe, Plus was named by Fast Company as one of the World’s Most Innovative Companies. Partners including TRATON GROUP’s Scania, MAN, and International brands, Hyundai Motor Company, Iveco Group, Bosch, and DSV are working with Plus to accelerate the deployment of next-generation autonomous trucks. If you’re ready to make a huge impact and drive the future of autonomy, Plus is looking for talented individuals to join its fast-growing teams. Our autonomous-driving fleet generates petabyte-scale sensor and system data. In this role, you will own critical parts of the path that makes this data reliable and useful—from high-throughput recording on the vehicle to transfer, validation, cataloging, and efficient access for replay, analytics, and machine learning. You will work primarily in modern C++ and Python, solving systems challenges across resource-constrained vehicle computers and large-scale offline infrastructure. We welcome engineers from systems, robotics, storage, or data-infrastructure backgrounds; prior autonomous-vehicle experience is helpful but not required. We are open to candidates at either the Software Engineer or Senior Software Engineer level. Level will be determined by experience, technical depth, scope of ownership, and demonstrated impact. You do not need experience with every technology in our stack; we value strong fundamentals, ownership, and the ability to learn. Responsibilities: Design and evolve high-throughput C++ systems that continuously record vehicle sensor and runtime data, selectively capture events, and collect system telemetry while operating safely under CPU, memory, disk, and network constraints Build reliable Python data-plane services and libraries for vehicle-data transfer, ingestion, validation, domain-specific format conversion, metadata extraction, cataloging, and storage lifecycle management Evolve versioned vehicle-data formats and their C++ and Python APIs, including indexing, serialization, compression, schema evolution, and backward compatibility Evolve columnar and lakehouse representations and access APIs for vehicle data, improving scalability and performance for fleet-scale mining, replay, and analytics Ensure that your work is performed in accordance with the company’s Quality Management System (QMS) requirements and contribute to continuous improvement efforts Required Skills: - BS, MS, or PhD in Computer Science or a related technical field, or equivalent practical experience - Programming experience in modern C++ and working proficiency in Python for services, libraries, and tooling - Linux systems knowledge, including concurrency, memory and resource management, filesystem and storage I/O, networking, debugging, and performance profiling - Self-driven with a strong sense of ownership: a quick learner who is eager to take responsibility and drive projects forward end to end Preferred Skills: - Familiarity with protobuf, gRPC, compression or media codecs, and native C++/Python bindings - Experience with autonomous vehicles, robotics, ROS or ROS 2, robotics log formats such as rosbag or MCAP, or other high-throughput recording and telemetry systems - Experience with columnar data formats or lakehouse table technologies such as Parquet, Delta Lake, or Apache Iceberg ## Your opportunities joining PlusAI Work, learn and grow in a highly future-oriented, innovative and dynamic field. Wide range of opportunities for personal and professional development. Catered free lunch, unlimited snacks and beverages. Highly competitive salary and benefits package, including 401(k) plan. ## 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.
