Woven by ToyotaWe are looking for an AI Platform Engineer who will enable teams developing and operating AI products to deliver high-quality AI capabilities faster, more safely, and on a sustainable basis. This position is not responsible for developing individual product features. Instead, the mission is to design, implement, and operate the shared platforms, workflows, and guardrails required for AI product development, evaluation, release, and operations. By reducing manual work and reliance on individual knowledge, you will improve development productivity, operational efficiency, and the quality and reliability of AI outputs across the organization. From an MLOps perspective, you will build and improve systems that support reliable operations through the management of models, data, experiments, evaluation results, and releases; CI/CD; infrastructure configuration management; monitoring, log collection, and alerting; and automation of incident response. You will also build mechanisms with validation workflows, policies, and evaluation methodologies, including agent-based code review. From an LLMOps perspective, you will drive the design and operation of feedback loops that collect and organize user feedback, usage logs, AI quality evaluation results, incidents, and failure cases, and use these insights to improve agents and tools. You will be expected not only to experiment with emerging technologies, but also to turn them into solutions that can be continuously used in real development environments, with due consideration for security, quality, reproducibility, and operational sustainability. You will work closely with product development teams, ML engineers, and security and cloud infrastructure stakeholders to evolve a reusable AI Platform that supports multiple products. This position reports to a functional leader. The work arrangement is hybrid, and travel to Woven City several times per month is required. Responsibilities include designing, implementing, and operating MLOps/LLMOps platforms and shared workflows; building systems that enable the management and traceability of models, prompts, agent configurations, evaluation data, experiment results, and release information; partnering with AI Quality Evaluation Engineers and product development teams to build feedback loops that support evaluation execution, regression evaluation, and release decisions; building and operating mechanisms to visualize and monitor LLM output quality, safety, consistency, latency, cost, and usage; establishing testing, monitoring, alerting, and rollback mechanisms to detect quality degradation and safety risks resulting from changes to LLM applications at an early stage; automating the development and operation of AI workloads using CI/CD, Infrastructure as Code, container and cloud platforms, and observability tools such as logs, metrics, and traces; and designing and implementing systems that enable the safe and effective use of agents for code generation, modification, and review, including agent-based code review, validation workflows, policies, and auditability.
Woven by ToyotaThe Map Solutions team provides AD/ADAS development with reliable access to high-quality map and geospatial data, which feeds machine learning model training, simulation, and system evaluation. We acquire, process, and maintain map data, and we build the tooling that helps teams across the company use a wide range of spatial datasets. You will join our Map Sourcing & Compilation sub-team, which prepares the map data used to develop and evaluate our next-generation driving system as it expands to urban roads. We are looking for a senior engineer with deep expertise in map data: vendor formats, map specifications, and the fine details that determine whether a map is suitable for driving. You will lead our in-house map releases from vendor data to a verified release. You will also help grow the team’s in-house expertise as this work scales. If you enjoy taking end-to-end ownership of a pipeline end to end, and you care as much about how data is checked as how it is built, we would love to hear from you. You will lead in-house map releases for onboard (in-vehicle) development end to end: specification, conversion, verification, and delivery. You will design and maintain in-house map specifications, along with the format conversion and post-processing pipelines that turn vendor data into them. You will build and run quality verification that ensures data integrity, and define the checks and metrics each release must pass. You will deliver ground-truth maps for offboard (non-vehicle) development, including ML labeling, simulation, and system evaluation. You will manage licenses for data and software used in in-house development, such as data usage agreements, to ensure compliant use. You will manage and evaluate vendor data coverage and quality against our standards. You will extend the pipeline to urban roads and to new map types, such as navigation and ADAS maps, for our next-generation system. You will document processes and mentor teammates so map data knowledge is shared across the team.
