What you'll do
The Project Reality
You'll join the Toyota Europe website development, specifically focusing on car configurator modules that millions of users interact with when building their ideal Toyota. Working alongside our Belgium campus colleagues, you'll be part of one of several iO teams delivering solutions within Toyota's enterprise technical environment alongside multiple partners.
Our experience with automotive clients shows that car configurators demand both technical precision and performance optimization—these aren't simple product catalogs but complex applications handling real-time pricing, availability, and customization logic across European markets.
What You'll Actually Do
Your daily work centers on JavaScript/TypeScript development using React and Redux Toolkit within Toyota's established technical stack. You'll build and optimize NodeJS/Express solutions following Backend for Frontend principles, ensuring smooth data flow between configurator interfaces and Toyota's backend systems.
The role involves working with modern development concepts that actually matter in production: state management patterns, server-side rendering, static site generation, and immutability principles. You'll configure and optimize bundling tools like Webpack and Vite, because performance directly impacts user experience in automotive e-commerce.
You'll work within our CI/CD processes using GitHub Actions, monitor application health through DataDog or NewRelic, and implement automated testing with Playwright. Recently, we've integrated GitHub Copilot for enhanced development productivity—something that proves valuable in complex enterprise codebases.
What Makes the Difference
Automotive or e-commerce experience helps because you understand the complexity of product configuration and real-time data integration. Experience working in multi-partner enterprise environments proves valuable—you'll navigate established processes while contributing technical expertise.
The most successful developers in this environment combine solid technical skills with collaborative problem-solving. You'll work within Toyota's enterprise standards while contributing iO's development expertise and innovative approaches.
