The position offers high flexibility with a remote-first model (unless you live near San Ramon) and allows you to touch a diverse tech stack including Node.js, HTML5, and various CRM integrations like Salesforce and Zendesk. **You might be a good fit if you:** * Have hands-on experience building integrations for enterprise contact centers. * Are comfortable moving quickly between different coding environments and third-party APIs. * Can translate complex technical feasibility studies into clear business requirements for customers. * Are open to "consultant-style" engineering, which includes up to 15% travel and high-level project management.
