Technical Consultant HR Access GTA - HR4YOU Expert

Project overview

Job Description — Technical GTA Consultant

Context of the mission

The DSIN is looking for an experienced GTA technical consultant (minimum 6 years of experience) to secure the testing and cutover of the GTA project.

The GTA project, launched in early 2025, is moving from detailed design to the testing phase. The HR department is already supported on the business side by a MOA (Management Assistance) function (steering, needs, business testing). A technical liaison is currently missing on the IT side, capable of preparing and equipping the testing phase, launching and understanding processes, and preparing the cutover to production.

The consultant will work on the HR Access [HR4YOU] solution (GTA module), within an integrated HRIS environment with Administrative Management (GA), Payroll, and soon GTA.

Positioning

The consultant will report to the DSIN GTA project manager and will work in tandem with the HR DRH AMOA: the AMOA will handle business needs and testing, while the consultant will be responsible for the technical implementation of testing and cutover.

Missions and activities

The mission covers three successive blocks: preparing for testing, technically conducting testing, and then preparing and executing the cutover.
