About Seed-X: Seed-X is an innovative, high-growth AgTech company revolutionizing the AgriTech industry. We leverage proprietary AI, machine vision, and deep learning algorithms to analyze seeds at the individual level, providing unmatched insights into genetic purity, quality, and germination potential. Our technology enables breeders and producers to drastically improve seed quality, increase yields, and ensure a more secure and sustainable food future. Join us as we transform the global seed and grain supply chain.

About the RoleSeed-X is looking for a visionary Principal / Staff Software Engineer to own, architect, and elevate our backend ecosystems, machine learning infrastructure, and cloud platforms. In this dual-impact role, you will act as a premier individual contributor and a technical beacon for the engineering team. You will bridge the gap between advanced backend engineering, scalable MLOps, and robust cloud infrastructure, ensuring our production-grade platforms are highly available, observable, secure, and built to scale. If you thrive on solving complex distributed systems problems and setting the gold standard for engineering excellence, we want you on board.

Key ResponsibilitiesTechnical Leadership & Architecture• Lead the architectural design, evolution, and scaling of our distributed backend microservices and machine learning platforms. • Establish, champion, and enforce engineering best practices across the organization, including rigorous code reviews, automated testing, design docs, and security protocols. • Mentor and coach senior engineers, fostering a culture of technical curiosity, continuous learning, and high execution velocity.

Backend & Infrastructure Engineering• Design and implement high-performance, resilient, and secure cloud-native solutions using Python and modern web application frameworks. • Architect and optimize data layers, ensuring database designs (SQL and NoSQL) are tuned for high throughput, low latency, and long-term scalability. • Drive the containerization and orchestration strategy using Docker and Kubernetes to ensure seamless deployments and efficient resource utilization.

MLOps & Cloud Operations• Build and maintain robust MLOps infrastructure to streamline the entire ML lifecycle—from data pipelining and model training to production deployment and monitoring. • Own and secure our AWS cloud infrastructure, optimizing complex networking setups including VPCs, DNS, ingress controllers, and service meshes. • Architect end-to-end CI/CD pipelines and DevOps automation to facilitate reliable, friction-free daily deployments. • Cultivate absolute system visibility by implementing comprehensive observability stacks (Datadog, Prometheus, Grafana, OpenSearch/ELK) and distributed tracing.
