Senior Integrations Engineer

About the Role This is a senior individual contributor role on a small integrations team, building the backend services powering a cold-chain risk-management platform that protects pharmaceutical and perishable shipments worldwide. You will own data-heavy distributed systems that contextualize IoT monitoring data and quantify shipment risk in real time, working closely with leadership at a growth-stage company where your contributions ship fast and carry genuine impact. What You'll Do Design and build backend services for a logistics orchestration and decision-intelligence platform. Own end-to-end partner data flows, from multi-vendor ingestion and normalization through warehousing, observability, and on-call support. Build and maintain external partner-facing operational integrations across APIs, webhooks, queues, carriers, sensors, and third-party vendors. Develop predictive systems for on-time, in-full (OTIF) performance and automate exception-handling workflows. Design and operate event-driven architectures using messaging systems such as Kafka or RabbitMQ. Deploy and operate containerized services on cloud infrastructure, maintaining high reliability for production workloads. What We're Looking For 5 or more years of backend engineering experience building scalable, data-intensive distributed systems. Hands-on proficiency in Python and TypeScript/Node.js; strong Java experience is a plus. Proven ownership of external partner-facing operational data integrations, not primarily internal platform, DevOps, or ETL-only work. Experience with IoT data ingestion, processing, and contextualization. Strong proficiency with relational databases and data modeling (SQL); familiarity with NoSQL databases is a plus. Experience with event-driven architectures and messaging systems (Kafka, RabbitMQ, or similar). Hands-on experience with Docker and Kubernetes for containerization and orchestration. Experience deploying and operating services on AWS, GCP, or Azure. Solid grasp of API design, including REST and/or gRPC. Strong engineering practices: testing, CI/CD, monitoring, and observability. Ability to operate independently and take full ownership in a small team setting. Background in logistics, supply chain, cold chain, or IoT-focused products is a strong plus. Prior experience at a growth-stage or Series A company is a plus. Compensation & Benefits Base salary $130,000 to $160,000 annually, plus equity and a cash bonus. Visa sponsorship is available. Location Fully remote, US-based.
