    • Deep understanding of REST APIs (designing, consuming, rate limits, authentication flows)
    • Hands-on experience with OAuth 2.0 and token lifecycle management
    • Experience integrating with third-party APIs, including major CRM platforms (HubSpot, GoHighLevel, Salesforce, etc.)
    • Comfortable working with JSON, webhooks, and event-driven systems
    • Experience with async processing and queues (BullMQ, SQS, RabbitMQ, etc.)
    • Solid understanding of retries, idempotency, and data consistency
    • Ability to design and maintain reliable sync pipelines
    • Strong debugging and problem-solving skills

    • AI tooling familiarity

    • Competitive salary: $2,800 – $3,800 USD/month (PJ contract)
    • Unlimited PTO and true flexibility
    • Team lunches and regular team-building activities

    • Must have a flexible schedule and be available to work during U.S. hours (MST)
    • Strong written English required
    • Comfortable speaking English in meetings and technical discussions
