• Winkelbezoeken om functionaliteit te valideren en feedback op te halen

Je krijgt veel ruimte om te innoveren, initiatief te nemen en het Mendix-landschap toekomstbestendig te maken.

Wat breng je mee?

• 5+ jaar Mendix-ervaring (Advanced/Expert is een pré)
• Je ontwerpt schaalbare Mendix-architecturen
• Je hebt integratie-ervaring met SAP, APIs, Mendix-apps en AWS
