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 data and simulation platforms are only as valuable as what people can do with them. In this role, you will own the product surface on top of those platforms — the web applications, APIs, and backend services that autonomy and ML engineers, operations and road-test teams, and external partners use to find data, author and run simulations, and act on the results. You will work across the full stack, from relational data models and Python services to modern TypeScript interfaces, turning ambiguous engineering workflows into tools people rely on every day. We welcome engineers from product, web platform, or developer-tooling 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 ship fullstack applications end to end: Python services and REST APIs, relational data modeling, asynchronous jobs, modern TypeScript frontend interfaces, deployment, testing, observability, and production reliability Build scenario authoring and management tools, including interactive editors for creating, parameterizing, and versioning test scenarios, and reproducible scenario libraries shared across teams Build interfaces for large-scale simulation and drive-log replay: launching and tracking runs, browsing results, comparing regressions across releases, and triaging failures down to individual scenarios Build shared application foundations — authentication, access control, multi-tenancy, and API conventions — that serve internal engineers, operations teams, and external partners from one coherent platform 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 - Production fullstack experience spanning backend services and REST APIs, relational data modeling and SQL, and modern frontend development (e.g., React/TypeScript) - Working proficiency in Python for services, libraries, and tooling - Ability to work directly with users to turn ambiguous engineering workflows into simple, reliable interfaces - 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: - Experience building interactive or visual web-based tooling, such as canvas, WebGL, Electron, or map- and geometry-based editing - Familiarity with Docker, Kubernetes, and CI/CD for deploying and operating web services - Experience presenting large datasets, time-series, or log data behind responsive interfaces - Experience building user behavior tracking and analysis into web products: instrumenting frontend/backend telemetry, and analyzing usage data to guide product iteration. - Experience with autonomous vehicles, robotics, or simulation and scenario-based testing - ## Experience with data visualization at scale ## 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.
