Senior Integrations Engineer

About the Role This is a senior individual contributor (IC) backend engineering role at a well-funded Series A startup building an AI-enabled, device-agnostic risk-management platform for cold-chain logistics. The platform helps pharma and perishables shippers and carriers reduce product loss, improve operational efficiency, and make smarter decisions in real time — answering who, what, when, where, and how for every shipment. You'll be a key technical voice on a lean, high-velocity team of ~27, designing and shipping the distributed systems that sit at the heart of the product. Your work directly protects high-value shipments that people depend on. What You'll Do Design and build backend services powering the logistics orchestration and decision-intelligence platform. Own data-heavy distributed systems that contextualize IoT monitoring data and quantify shipment risk in real time. Build predictive systems for OTIF (on-time, in-full) performance and automate exception-handling workflows. Architect and maintain event-driven pipelines for high-volume IoT data ingestion and processing. Partner closely with engineering leadership and cross-functional stakeholders to influence product and architecture decisions. Champion software engineering best practices: testing, CI/CD, monitoring, and observability. Build for scale and reliability in a domain where uptime and accuracy genuinely matter. What We're Looking For Required 5–15 years of backend engineering experience building scalable, distributed systems. Proficiency in at least one modern backend language: Python, Java, Go, or Rust (strong Java and/or Python preferred). Hands-on experience designing and operating data-heavy distributed systems. Experience with IoT data ingestion, processing, and contextualization. Proficiency with relational databases (SQL) and data modeling; experience with NoSQL databases and ETL pipelines is a plus. Experience building event-driven architectures and working with messaging systems (Kaf
