Job description
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.

Integration Development & Data Processing
Build and maintain production integrations using , 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
