Senior Fullstack/Frontend Engineer

About the Role

We’re looking for a Fullstack Engineer with deep expertise in Frontend technology to join our Mapping Engineering team. You’ll be responsible for building web-based tools and interfaces that empower engineers, operators, and stakeholders to interact with our distributed mapping systems. Your work will directly impact the safety and scalability of autonomous driving. You’ll collaborate closely with product managers, backend engineers, machine-learning engineers, and domain experts across Localization, Perception, and Simulation to deliver high-quality, user-centric tools that support the full map lifecycle.

Responsibilities

• Architect and implement performant, scalable, and maintainable frontend systems for AV mapping applications across web and embedded platforms.
• Design intuitive, data-rich user interfaces to visualize complex geospatial and mapping data, supporting workflows such as map editing, validation, and release.
• Collaborate closely with backend, simulation, localization, and perception teams to define robust data contracts and ensure seamless integration across systems.
• Lead the frontend development lifecycle for high-impact projects—defining milestones, aligning stakeholders, and mentoring engineers across functions.
• Drive technical excellence in frontend engineering by conducting design reviews, enforcing UI/UX best practices, and setting standards for code quality, testing, and documentation.
• Optimize rendering performance and responsiveness for large-scale map data and real-time updates.
• Serve as a Subject Matter Expert (SME) in frontend architecture, component design, and visualization frameworks within the Mapping organization and across AV domains.
• Contribute to roadmap planning and hiring strategies to grow frontend expertise across the team.

Qualifications

• 5+ years of experience building and maintaining production-grade frontend applications.
• Bachelor's Degree in Computer Science or related field, or relevant work experience.
• Proven experience owning and shipping user-facing products, ideally in high-performance or data-intensive domains.
• Strong proficiency in modern JavaScript/TypeScript, React (or similar frameworks), and state management libraries (e.g., Redux, Zustand).
• Deep understanding of frontend performance optimization, accessibility, and responsive design.
• Experience working with geospatial data, map rendering libraries (e.g., Mapbox GL, Deck.gl, OpenLayers), or data visualization frameworks (e.g., D3.js).
• Familiarity with RESTful APIs, WebSockets, and GraphQL.
• Demonstrated success in leading frontend initiatives, mentoring engineers, and working with cross-functional stakeholders.

Preferred Qualifications

• 7+ years of experience building and maintaining production-grade frontend applications.
• Experience with AV mapping systems, HD map data pipelines, or automated cartographic error detection.
• Knowledge of computer vision or machine learning workflows related to map labeling or perception.
• Deep experience with Node.js internals and performance tuning.
• Experience designing performant geospatial services, coordinate systems, and transforms.
