You will be part of a focused, self-sufficient two-person engineering team (working alongside a Senior Developer) building a multi-tenant dashboard application from scratch. The client has developed a Proof of Concept (POC), which will serve purely as a reference for business logic to help us architect and write the new system from the ground up.

What We're Looking For

• Commercial Experience: 3+ years of hands-on experience as a Fullstack Developer working with Vue.js and .NET (C#)
• Product Thinking: Self-driven approach to feature design and technical implementation, capable of defining functional requirements and basic user flows independently to ensure fast, continuous delivery.
• Database & Cloud: Practical knowledge of SQL Server and core Azure services
• Integrations: Experience working with REST APIs and third-party integrations (e.g., e-commerce platforms, ERP systems)
• Self-Reliance: Ability to take ownership of assigned tasks and collaborate effectively in a small, agile team
• Language Skills: Good command of English (B2+) to ensure smooth communication
