We use Go for scalable backend services, TypeScript & React for frontend development, and Python for AI & ML services. Our infrastructure is hosted on AWS with Kubernetes for orchestration and Terraform + Argo CD for configuration management. Key systems include S3, PostgreSQL, Kafka, OpenSearch, LLMs, and other AI models., * Design and scale backend services, APIs, and data pipelines that power Collate's products.

 * Deliver end-to-end, production-ready features in partnership with product, design, and AI engineering.
 * Balance iteration speed with technical rigor to ensure systems scale reliably.
 * Create internal tools and workflows that accelerate engineering productivity.
