Description

Mapfre is hiring a Senior Frontend Engineer with deep Angular expertise for its proprietary AI-agentic software development platform in the Corporate Technology area, Reef Lab. The platform uses specialized AI agents to cover the whole software lifecycle: defining requirements, generating and reviewing code, building interfaces and running automated testing. The hire will build the platform interface, define the technical guidelines AI agents follow when generating frontends for other projects, and support teams in the various countries where the platform is deployed.

Responsibilities

Define the structure, patterns and standards of the platform's Angular frontend
Develop complex interfaces that clearly expose the work of AI agents throughout the software lifecycle
Make technical decisions on the evolution of the frontend while staying involved in active coding
Collaborate closely with product and backend profiles to guarantee a coherent end-to-end experience
Ensure performance, accessibility and code quality across the whole presentation layer
Establish the frontend technical design guides: module structure, state management, conventions that the rest of the team will follow
Audit and raise the technical level of the existing Angular code, participating in code reviews of other developers
Give technical directives to AI agents so they build frontends according to the defined standards and help build the platform itself
Provide technical support to the teams of the different countries using projects deployed through the platform

Requirements

Minimum 10 years of frontend development experience, working intensively with Angular in large-scale production projects
Proven experience in more than 10 complex application projects where the frontend technical design was defined from scratch
Expert, demonstrable mastery of TypeScript and the Angular ecosystem: RxJS, NgRx or similar, reactive forms, lazy loading
Track record of making high-level technical decisions on frontend design while staying active in daily development, not only design or review tasks
Strong experience using AI agents to build frontends, as well as developing with coding agents like Claude Code, GitHub Copilot, OpenCode or OpenHands
Broad knowledge of the UI/UX solutions ecosystem: design systems, component libraries, tools like Figma, and how to translate them into a real Angular frontend
Frontend testing experience with Jasmine, Karma, Cypress, Playwright or similar in production projects
Experience with Spec Driven Development (SDD) methodology
English at C1 level, with ability to collaborate on international projects and teams
