We are committed to preventing all forms of discrimination and to providing all our candidates with equal opportunities regardless of their gender and gender expression, disability, origin, religious belief and sexual orientation or any other criteria.

CONTEXT

As a Senior Full-Stack Software Engineer, you will design, build, and operate Domain APIs based on Domain-Driven Design principles.

You will transform complex business capabilities into clear domain models, well-defined bounded contexts, reliable APIs, and maintainable software. Working across both backend and frontend, you will help build business-critical applications and platform capabilities used across Edenred Group.

This is not simply an API implementation role. You will actively contribute to understanding the business domain, defining its ubiquitous language, identifying aggregates and invariants, designing clear application boundaries, and translating these decisions into production-grade software.

You will work within a cross-functional engineering team, collaborating with software engineers, architects, product managers, security specialists, platform teams, and business stakeholders across multiple countries and business units.

This is an end-to-end engineering role. You will contribute across the entire software development lifecycle, from domain discovery and technical design to frontend and backend implementation, automated testing, deployment, observability, and production operations.

YOUR ROLE

• Build strategic Domain APIs and products used across Edenred Group.
• Model complex business capabilities using pragmatic Domain-Driven Design.
• Shape bounded contexts, domain models, API contracts, and integration patterns.
• Solve complex business and technical problems in an international environment.
• Influence product and technical decisions alongside engineers, architects, and product managers.
• Work with modern frontend technologies, .NET services, REST APIs, event-driven architecture, and cloud-native infrastructure.
• Contribute to architecture, engineering standards, developer experience, and continuous improvement.
• Own the complete stack: you design it, build it, test it, deploy it, monitor it, and improve it.
• Help less-experienced engineers grow through technical guidance, constructive feedback, and knowledge sharing.

If you enjoy turning complex business domains into software that is simple where possible, rigorous where needed, and reliable at scale, this is a strong opportunity to make a meaningful impact.

YOUR PROFILE

You have over eight years of experience and possess the following skills:

• Proven experience working as a Senior Full-Stack Software Engineer on production-grade applications.
• Strong collaborative mindset and clear, precise communication.
• Product and domain mindset, with the ability to understand business capabilities and user needs beyond individual technical tasks.
• Strong ownership mindset aligned with the principle: you design it, you build it, you run it.
• Fluent English and the ability to work effectively in an international environment.
• Strong experience with C# and .NET, building production APIs, backend services, and distributed applications.
• Strong experience with TypeScript and at least one modern frontend framework such as React, Angular, or Vue.js.
• Strong practical understanding of Domain-Driven Design
• Ability to collaborate with business and product stakeholders to translate ambiguous business concepts into explicit domain models.
• Experience designing and maintaining Domain APIs with clear, versioned, and well-documented contracts.
• Good understanding of software architecture principles, including separation of concerns, modularity, clean architecture, dependency inversion, and appropriate coupling.
• Strong experience with automated testing across the stack, including unit, integration, API, component, contract, and end-to-end tests.
• Experience testing domain behaviour, business invariants, API contracts, and integration scenarios.
• Experience with frontend testing tools and practices, such as Jest, Vitest, Testing Library, Cypress, or Playwright.
• Experience with event-driven architecture and asynchronous communication, ideally using Kafka or a comparable messaging platform.
• Ability to reason about data ownership, consistency, idempotency, auditabilit
