Job summary

Expereo International is building a modern platform for quoting, ordering and activating services. We seek a Full Stack Engineer with strong React/TypeScript frontend skills and backend exposure in Node.js and C#/.NET, to own end-to-end features in a hybrid remote/onsite environment.

You will collaborate with Commercial STO and DevOps to ship production-ready surfaces on AWS, maintain integrations with Salesforce, and drive adoption through robust testing and documentation.

Qualifications

• Five plus years of professional software engineering with production React and TypeScript front ends.
• Node.js and TypeScript services in production.
• REST and GraphQL APIs with contract-first OpenAPI as a working method.
• Delivery path ownership: CI/CD, deployment, monitoring.
• Ability to read and write C#/.NET at integration points.

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.
• Turn requirements from commercial and operations users into production-quality experiences that make their daily work faster and less error-prone.
• Keep the front-end codebase coherent as it grows: shared components, consistent patterns, and a design language across screens.
• Bring the consumer’s view into API design: what the interface needs to look like for the front end to be simple, fast, and correct.
• Implement the service layer each feature needs, REST or GraphQL, working contract-first from OpenAPI specifications.
• Build and maintain the integrations with Salesforce and other core systems that commercial data flows through.
