Job summary

Expereo International is seeking a Full Stack Engineer to own the front-end with React and TypeScript, while connecting the service layer to the backend in a full-stack role. You will work across the OpenAPI-driven service layer and integrations with Salesforce and other core systems, ensuring secure, scalable features end to end.

You will join the Commercial STO, delivering in a hybrid cloud environment with CI/CD practices, tests, and living documentation.

Qualifications

• Five plus years of professional software engineering with production React and TypeScript front ends.
• Node.js and TypeScript services in production, and comfort implementing the layer between the front end and the backend for the features you own.
• REST and/or GraphQL APIs implemented and consumed in production, with contract-first OpenAPI as a working method.
• Ownership of the delivery path for what you ship: you configure, deploy, observe, and operate your own work on a managed cloud, with CI/CD as part of how you work.
• Software engineering discipline: testing, code review, Git, feature flags, and reproducible builds.

Responsibilities

• Own the React and TypeScript front ends of the surfaces you work on, from component structure and state management to data fetching, caching, and performance.
• Implement the service layer each feature needs, REST or GraphQL, working contract-first from OpenAPI specifications.
• Build and maintain integrations with Salesforce and other core systems so data flows correctly downstream.
• Implement authentication and authorization for the features you build, with secure-by-default design.
• Read and work at C#/.NET integration points when a feature crosses them.
• Own the delivery path: configure, deploy, observe, and operate your own surfaces on a managed cloud.
• Write tests that give real confidence and drive automated quality gates in CI.
• Collaborate with product owners and other teams; participate in design and technical decision-making.
