• Implement resilient integration architectures, including handling webhooks, rate limiting strategies, and reliable retry mechanisms for external API calls.
• Collaborate with an exceptional team of engineers to solve challenging problems.
• Maintain clear documentation for application changes, development updates, and API integration flows.

Requirements

• 5+ years of meaningful experience with backend & frontend development (React and Node.js) and APIs, in a real production environment.
• Proven experience building complex integrations with third-party APIs and a strong understanding of CRM data models (Leads, Contacts, Accounts, Custom Objects).
• Deep technical knowledge of the Salesforce ecosystem, including Salesforce REST/SOAP APIs, Bulk API, SOQL/SOSL, and configuring Connected Apps.
• Strong understanding of modern authentication protocols, specifically OAuth2 (Authorization Code, Client Credentials flows), JWT, and secure token lifecycle management (e.g., Refresh Token Rotation).
• B.Sc. in Computer Science or equivalent experience.
• Strong proficiency in HTML, CSS, and JavaScript.
• Solid understanding of databases, including SQL and MongoDB.
• In-depth understanding of the DOM, client-side performance, and browser compatibility.
