Senior Integrations Engineer

Accountabilities:: Design and build scalable backend services powering a logistics orchestration and decision-intelligence platform. Own end-to-end partner data flows, from multi-vendor IoT data ingestion and normalization through data warehousing, observability, and production support. Build and maintain event-driven architectures using messaging technologies such as Kafka or RabbitMQ. Develop predictive systems supporting on-time, in-full (OTIF) performance and automate workflows for handling logistics exceptions. Design and maintain integrations with external partner APIs, webhooks, queues, carrier feeds, sensor streams, and vendor systems. Process and contextualize IoT monitoring data to support real-time shipment risk analysis and predictive workflows. Deploy and operate containerized backend services on cloud infrastructure, maintaining reliability appropriate for mission-critical logistics applications. Implement strong testing, CI/CD, monitoring, observability, and operational practices across production services. Collaborate closely with engineering leadership and cross-functional teammates to deliver solutions rapidly in a growth-stage environment. Take ownership of technical problems across the integration lifecycle, from system design and development through deployment, troubleshooting, and on-call support. Requirements 5+ years of backend engineering experience building scalable distributed systems. Hands-on proficiency with Python and TypeScript/Node.js; strong Java experience is a plus. Demonstrated experience owning external, partner-facing operational data integrations end to end, rather than focusing exclusively on internal systems, DevOps, ETL, or general full-stack development.
