VTS runs a complex, high-volume revenue motion — Salesforce CPQ feeding NetSuite via middleware, with mid-contract amendments involving upsells, cross-sells, volume changes, downgrades, and product churn happening continuously. The integration layer that connects these systems is functional but manual-heavy, underdocumented, and not built to scale. Furthermore, our CRM and CPQ system requires customization in order to optimize deal workflows to ensure accuracy and timely contract execution. This is not a Salesforce admin role with a developer title. We need someone who writes clean Apex, understands how CPQ order data needs to land in an ERP, knows what good middleware design looks like, and treats release management as a professional discipline — not an afterthought. Alongside our RevOps system team and Salesforce Architect, you'll work closely with our Finance and Sales teams. You will be one of the internal technical voice that evaluates and challenges what those partners propose — knowing when to push back when something is wrong. ** Please note that this opportunity is located in New York, NY, and requires this hire to work from our office 4 days a week. ** What you can expect as a Senior Salesforce & Integration Engineer: Salesforce / CPQ Own the technical customization and development of Salesforce — LWCs, Apex classes/triggers etc along with flows Manage the scaling of custom objects that drive pre/post sales teams in meeting customer needs and internal workflow management Write and maintain Apex triggers, classes, and flows that support Salesforce and CPQ business logic — with test classes that hit 90%+ coverage as a floor, not a ceiling Integration Architecture & Development Partner with third-party implementation firms on the integration build and growth connecting Salesforce CPQ to NetSuite — be the internal technical reviewer, not just the observer Own the internal integration layer as it matures: field
