PAXAFE is a logistics orchestration & decision intelligence SaaS platform that helps Cold Chain planning, logistics and quality teams consolidate their transportation data agnostically, digitize and automate product quality and lane qualification decisions, and operationalize prescriptive recommendations in the transportation network.

​

Acting as the cold chain trust layer whose mission is to drive towards zero transportation waste, PAXAFE works with cold chain manufactures and service providers to reduce product loss, improve operational efficiencies and make more informed decisions in real-time.

PAXAFE's vision is to become the backend intelligence infrastructure that powers every temperature, time and value-sensitive shipment in the world.

PAXAFE is backed by great VCs (Framework Venture Partners, Ubiquity Ventures, Venture53, RoseCliff Ventures, etc.) and CVCs (Microsoft M12, Northwestern Mutual, Greenlight Re)

The Role

We're seeking an experienced Senior Integration Engineer to join our engineering team and lead the development of critical data integrations for our cold chain logistics platform. You'll be responsible for building and maintaining complex integrations that process shipment tracking data, device telemetry, and temperature monitoring feeds from diverse logistics partners and IoT devices—enabling real-time visibility and proactive risk management for temperature-sensitive pharmaceutical shipments.

This role requires someone who thrives on solving complex data challenges, from debugging international geocoding issues to optimizing high-volume telemetry processing workflows and reconciling conflicting data across multiple vendor systems. You'll work directly with major pharmaceutical clients to ensure their critical shipments maintain temperature integrity throughout the supply chain.

What You'll Do

Integration Development & Data Processing

• Build and maintain production integrations using http://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

Real-time Monitoring & Alert Systems

• 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

Data Quality & Validation

• 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

Database & Infrastructure

• 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
• Create database migration scripts and maintain schema documentation

Customer Implementation & Support

• Debug production issues across multiple client environments
• Optimize integration performance for high-volume data streams
• Support Linear project management workflows
• Document PAXAFE integration workflows, schemas, and other specifications

Who We're Looking For

Required Technical Skills

• 4+ years building production data integrations with complex transformation requirements
