.NET Developer

Duration: Initial 3–6 months, with possibility of extension

Boldare is an Agile-powered company with nearly two decades of international experience in product development and consulting. We help our clients redefine their industries by co-creating digital products their users truly need. Since 2004, Boldare has delivered over 300 solutions for clients across the globe — from Western and Northern Europe to the UK, North America, the Middle East, Southeast Asia, and Australia. Our 80+ specialists work fully remotely across Europe, combining technical excellence with a strong product mindset.

Currently, we’re looking for a .NET Developer to join a new, long-term project for one of our international clients. This is a strategic greenfield initiative, focused on building a high-quality integration platform from scratch. The system will handle millions of users across three key regions (US, UK, EU), integrating with platforms such as Salesforce Commerce Cloud (SFCC), CrowdTwist, and Amplience CMS.

We’re initially looking for someone available for approximately 3–6 months, with a strong possibility of extending the collaboration beyond that period depending on project development and mutual fit.
