B2B

Salesforce

We’re looking for a Senior Integration Engineer to join our team and contribute to the improvement and further development of a business-critical Salesforce-based platform used in a large-scale B2B environment.

In this role, you’ll work on a live production system with integrations across Salesforce Commerce, Sage, and MuleSoft, helping resolve existing issues, improve core business flows, and support the ongoing evolution of the platform. This is a hands-on role for someone who is comfortable working with complex integrations, backend logic, and business-critical workflows in an established system.

About the project

Our client is a fast-growing U.S.-based company operating in the industrial packaging domain and serving businesses across the U.S. and Mexico.

The project is a Salesforce-based portal with integrations across Salesforce Commerce, Sage, and MuleSoft. A full technical and QA audit has already been completed by our team, uncovering gaps in UX, functionality, performance, and backend logic. We are now looking for an engineer who can help address these issues, improve the platform’s core flows, and support the next stage of product development.
