Data Engineer (SE / Sr SE)

Santa Clara, CAData Engineering – Data Infrastructure /Full-time /HybridPlusAI is a Physical AI company pioneering AI-based virtual driver software for factory-built autonomous trucks. 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.Knowing how well our virtual driver drives — and why it fell short — is what lets us ship with confidence. In this role, you will own that loop end to end: the metrics that quantify driving performance, the pipelines that compute them at fleet scale, the analysis that turns them into judgments about autonomy behavior — including where on the map that behavior changes — the data and tooling that gate software releases, and the agentic workflows that take a detected issue from triage to a proposed fix. You will work primarily in Python across large-scale data processing, geospatial analytics, evaluation frameworks, and LLM-powered automation. We welcome engineers from data engineering, analytics, geospatial, evaluation, or robotics backgrounds; prior autonomous-vehicle experience is helpful but not required.We are open to candidates at either the Engineer or 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:Define and compute driving performance metrics — covering safety, comfort, progress, interventions, and compliance — and build the scalable pipelines that evaluate them consistently across fleet and simulation dataAnalyze road-test and simulation data in depth to identify trends, regressions, and anomalies in autonomy behavior, and turn them into clear findings that engineering teams act onBuild geospatial analytics over fleet driving data: map-matched metrics, route and corridor performance, location-based clustering of events and issues, and geographic coverage analysis that shows where the virtual driver performs well and where it strugglesBuild the data foundations and tooling for release management, including release-over-release comparisons, readiness and gating criteria, and traceable evidence supporting release decisionsBuild AI agentic workflows that triage detected issues at scale — clustering and deduplicating failures, attributing root cause, routing to the right owners, and proposing fixes with supporting evidence for engineering reviewEnsure that your work is performed in accordance with the company's Quality Management System (QMS) requirements and contribute to continuous improvement effortsRequired Skills: BS, MS, or PhD in Computer Science, engineering, or a related technical field, or equivalent practical experienceProficiency in Python, with experience building scalable data processing systems or evaluation frameworksExperience developing metrics and analyzing large-scale time-series, event, or geospatial data, including principled metric definitions, validation, and error analysisExperience building LLM-powered or agentic workflows for data analysis, evaluation, or automationAbility to solve open-ended technical challenges and communicate findings clearly to engineering and program stakeholdersSelf-driven with a strong sense of ownership: a quick learner who is eager to take responsibility and drive projects forward end to endPreferred Skills:Experience with distributed data processing such as Apache Spark, and workflow orchestration such as Airflow or Argo WorkflowsFamiliarity with LLM agent frameworks (e.g., LangChain, LangGraph, or similar) and prompt/tool-orchestration patternsExperience with geospatial data and tooling, such as GIS formats, map matching, spatial indexing and joins, PostGIS, GeoPandas, or map-based visualization librariesExperience with release engineering, quality gating, or automated regression detectionExperience with autonomous vehicles, robotics, or other safety-critical systemsExperience building dashboards or analytics interfaces that expose metrics to users$130,000 - $200,000 a yearYour opportunities joining PlusAIWork, 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.We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
