## Description

You'll be architecting and scaling the core backend systems, APIs, and data infrastructure powering the next generation of defense intelligence tools. We move fast, ship often, and solve complex data and distributed systems problems with elegant, high-throughput solutions., * Architect Core Backend Systems: Design, build, and maintain low-latency, high-throughput APIs and microservices using TypeScript, Express, and Node.js (with Next.js server-side/API integrations where needed).

 * Own End-to-End Data & Infrastructure: Shape and own backend features from database schema design to production deployment on AWS.
 * Scale Data Storage & Analytics: Optimize relational workflows in PostgreSQL and build high-performance analytical queries and ingestion pipelines in ClickHouse and Databricks to fuse thousands of structured and unstructured defense data sources.
 * Power AI/ML Workflows: Build the data pipelines, retrieval systems, and backend services that feed our AI/ML models and deliver real-time intelligence to users.
 * Translate User Needs into Technical Architecture: Collaborate directly with product, data, and end-users to understand complex defense acquisition workflows and translate them into resilient backend architectures.
