42dot is a mobility AI company committed to solving mobility challenges with software and AI. As the Global Software Center of Hyundai Motor Group, 42dot pioneers the future of mobility by advancing the development of software-defined vehicles.
We develop safety-first, user-centric software-defined vehicle technologies that deliver the latest performance through continuous updates like smartphones. By advancing software and AI technology, 42dot envisions a world where everything is connected and moves autonomously through a self-managing urban transportation operating system.
Join our dynamic team as a Senior Frontend Engineer, where you will shape the user-facing layer of our virtual development platform for Software Defined Vehicles (SDV). Your work will define how internal engineering teams and external integration partners experience our SDV OS tooling - from the public API contract that drives partner integrations, through the real-time dashboard that visualizes vehicle state, to the 3D model views that bring the virtual vehicle to life. This is your chance to be at the forefront of automotive innovation, building the developer and partner experience for the autonomous driving platform of the future.
Design, document and evolve the public REST and Server-Sent Events API surface of our virtual vehicle platform, including OpenAPI specifications and generated partner clients.
Implement and maintain the production frontend in React and TypeScript: real-time vehicle state dashboards, vehicle variant management, partner-facing portals, configuration and scenario tooling.
Integrate 3D vehicle assets (glTF) into the frontend using three.js or react-three-fiber, in close collaboration with our product designer.
Build the developer experience around the schema: typed clients, runtime validation, mocks, contract tests, generated documentation.
Own resilience of streaming UI components: reconnection, backpressure, multiplexed event handling.
Participate directly in technical conversations with external integration partners, including API design reviews and partner-facing written guides.
Bachelor's degree in Computer Science or related field, equivalent practical experience.
5+ years of production experience with React and TypeScript, including end-to-end type safety.
Hands-on experience designing and evolving OpenAPI 3.x specifications and the tooling around them (validators, mocks, client generators).
Strong schema-first instincts (Zod, JSON Schema, runtime validation at boundaries).
Solid working understanding of REST and streaming protocols (Server-Sent Events, WebSocket).
Practical experience integrating 3D content in the browser with three.js or react-three-fiber: scenes, cameras, glTF loading, basic performance tuning.
Strong code review culture and ability to collaborate with backend and design counterparts.
Fluent English.
Frontend integration testing with Playwright or Cypress, including visual regression workflows.
Experience writing partner- or developer-facing technical content (HOWTOs, integration guides, release notes).
Working experience with multi-site, multi-national and multi-contributor teams.
Knowledge of automotive products, is a plus but not required.
