We operate across a range of markets, from financial services to healthcare, automotive, agribusiness, insurance, and many more. Experian invests in people and new advanced technologies to unlock the power of data. We have an amazing team of 25,200 people in 32 countries.\n Experian Partner Solutions is looking for Senior Web Engineers to build the products our partners white label as their own - embedded components that run inside partner applications, and hosted sites that carry a partner's brand. When a partner puts our software in front of their customers, our code runs under their brand, in their environment, with their reputation attached. There is no margin for \"it works on my machine.\"\nPredominantly JavaScript and TypeScript across the browser and the server - React on the front end, Node in our services and tooling.\nWe are building this team around AI-assisted development. That is not a perk in the job description - it is the operating model. You will spend a significant share of your time directing AI coding agents, reviewing what those agents produce, and being personally accountable for code you did not type character by character. You will report to the director of web development.\nManage web software end-to-end - develop, and support it in production. Ownership does not stop at the merge.\nDirect AI coding agents as your primary implementation method rather than hand-writing every line.\nDecompose features into work an agent can build reliably, and write the prompts and specs that make that possible.\nMake the architecture calls AI cannot make for you: interface and Api design, state and service boundaries, versioning, and backward compatibility for consumers who depend on your releases.\nDesign for environments you do not control, whether that is a hostile host page, an unfamiliar partner configuration, or an unexpected client of your Api.\nUse AI to create test suites and regression coverage, then look for what the generator missed: adversarial inputs, integration conflicts, and configuration edge cases.\nAgentic Responsibilities\nBreak complex features into AI-manageable tasks.\nReview AI-generated code for bugs, security, and architecture issues.\nWrite prompts that produce quality code.\nUse AI for testing while recognizing its limitations.\nDemonstrate architecture and system-design judgment.\nUnderstand where AI performs well and where it fall short.\n 5+ years experience building and shipping production web software, with ownership of what you built after it went live.\nBachelor's degree in a relevant field or equivalent experience.\nYou will have experience in JavaScript and TypeScript, applied across the browser and the server. We work in React and Node; expertise in a comparable ecosystem plus evidence you pick up new stacks quickly is equally welcome.\nComponent libraries, design systems, or SDKs consumed by teams outside your own - where breaking changes carry cost.\nServer-side or full-stack web work - Node services, APIs, and the integrations that connect a customer-facing product to the systems behind it.\nPractical web security awareness: injection and XSS vectors, authentication and session handling, dependency risk, and safe handling of sensitive data.\nExperience with DevOps and CI/CD, automated test and build tooling.\n Our uniqueness is that we celebrate yours.
