HRIS Developer H/F

Context

You will join a team building and evolving internal HR tools developed in .NET, in a context where many topics are still being structured and delivered. A key team member is moving internally, so the main objective is to ensure continuity, stabilize the existing applications, and accelerate delivery.

The HR information systems are used globally, with local needs (regulations, processes, practices) requiring country/entity-specific customizations.

Responsibilities

• Design, develop, and maintain back-end applications and services in C#/.NET for HR teams (operational tools, workflows, automation).
• Contribute to technical design: back-end architecture, patterns, code quality, performance, security, and maintainability.
• Build and enhance local customizations based on country/entity requirements (HR processes, regulatory constraints).
• Deliver integrations and interfaces: APIs, data synchronizations, business rules, and data quality improvements.
• Contribute to testing, documentation, and production releases (CI/CD if applicable).
• Support the creation and improvement of onboarding & training materials (guides, knowledge transfer, support processes).
• Collaborate with multi-site stakeholders (EMEA, Singapore, Africa) and coordinate with other offices when needed.

Profile

• Education: Engineering degree / Master’s in Computer Science (or equivalent). Open to strong junior profiles.
• Experience: Junior to confirmed experience in C#/.NET back-end development.
• C# / .NET (APIs, services, back-end development)
• SQL (queries, data modelling, performance mindset)
• Best practices: unit/integration testing, code reviews, documentation, Git
• Application integration experience (API management, messaging, ETL/interfaces)
• Exposure to HRIS / HR tools (HR workflows, reference data, HR operations)
• Experience in global/multi-country environments with local compliance constraints
• Hands-on, delivery-oriented, comfortable building and improving systems iteratively
• Ability to communicate with non-technical users (HR teams)
• Autonomous team player who enjoys structuring knowledge (onboarding/training)
• English : C1/C2 / French: an advantage
