• Build and maintain production integrations using Prismatic.io, handling complex payload transformations and multi-step workflows
• Process and normalize shipment tracking data from 3PL partners (UPS, Kuehne+Nagel, World Courier, DHL, FedEx)
• Implement robust error handling and retry logic for unreliable vendor APIs ensuring 100% of data is captured
• Design device selection algorithms to optimize telemetry data processing
• Create matching logic for automated shipment routing decisions
• Build integration deviation detection and alerting workflows
• Process device telemetry streams from multiple IoT providers (Sensitech, Tag-n-Trac, Elpro, Tive, Samsara, Controlant, Roambee, etc.)
• Calculate packaging thermal life and predict temperature breaches
• Implement 3PL/carrier milestone processing for shipment status updates
• Design dashboards for real-time integration health visibility for internal and external stakeholders
• Debug and resolve geocoding issues with international addresses using Mapbox and other APIs
• Implement comprehensive data validation for vendor payloads
• Build data quality monitoring and anomaly detection systems
• Create reconciliation workflows for mismatched shipment and device data
• Handle API (REST, GraphQL, SOAP), EDI (AS2), and legacy (email, SFTP) transmission implementations
• Design and optimize Supabase database schemas for high-volume telemetry data
• Write complex PostgREST queries for data retrieval and aggregation
• Implement efficient upsert patterns for real-time data updates
• Build data archival and retention strategies

• Experience with geocoding APIs and address normalization challenges
• Understanding of webhook patterns, REST APIs, and real-time data streaming
• Frontend experience for building integration monitoring dashboards
• Cold chain logistics and temperature-controlled shipments (pharmaceutical strongly preferred)
• Experience with 3PL data formats and tracking systems
• IoT device integration and telemetry processing
• Understanding of GxP compliance and pharmaceutical logistics requirements
• Knowledge of thermal packaging and temperature excursion management
• EDI/AS2 protocol experience
• Proven ability to debug complex data quality issues across multiple systems
• Experience handling inconsistent vendor data formats and missing fields
• Skills in reverse-engineering undocumented APIs and payload structures
• Understanding of retry strategies and error recovery patterns
• Experience with high-volume data processing optimization
• Obsessive attention to data quality and validation
• Ability to context-switch between multiple integration issues
• Strong debugging skills with distributed systems
• Experience managing vendor relationships and escalations
• Clear technical documentation and communication skills
• Experience with our specific tech stack is preferred but not required
