Senior Backend Engineer- CTI

Description Every nation has data. Few can protect it. Fewer still can act on it. Dream is the sovereign AI and national cyber-defense company for governments. We help nations secure their most critical systems, connect fragmented information at a national scale, and turn their most sensitive data into decisions, all fully sovereign. This is more than a job. It's a Dream job, where you'll work at a global scale alongside some of the best AI researchers, cyber operators, and government experts in the world. We defend nations against the most advanced threats in the world with a national security suite that offers AI-native resilience against APTs with visibility, insights and mediation across Posture, CTI, and Detection & Response, all fully sovereign. The Dream Job We're building Dream's Cyber Threat Intelligence platform - an AI-first product that harvests, contextualizes, and serves threat intelligence at scale. We're looking for a Python-native backend engineer to own the infrastructure that makes this possible. You'll design and build the systems that power both agentic AI workloads and large-scale data orchestration - exposing CTI insights as a service to UI components, APIs, and autonomous agents across the Dream ecosystem. This is a greenfield opportunity where you'll shape foundational architecture decisions on a new product with a small, high-impact team. The Dream-Maker Responsibilities Build the tooling and infrastructure that enables AI agents to consume and reason over threat data. Develop systems that harvest data from open and dark web sources, cross-reference signals, and contextualize raw intelligence into actionable insights. Serve curated CTI data to various consumers - dashboards, internal services, and other agents in the Dream platform. Instrument complex workflows with tracing and metrics - when things break in production, we need visibility to understand why. Design and scale agent-based systems along with robust evaluation frameworks.

Experience building and operating data pipelines, data lakes, or large-scale data infrastructure. Experience with distributed systems and the challenges they bring (consistency, failure modes, debugging across services). Familiarity with microservices architecture and tooling (Docker, Kubernetes). Experience with NoSQL databases. High independence - you thrive with autonomy and ownership in ambiguous environments. Advantages: Experience building distributed systems. Data management at scale - ETL, data quality, governance. Experience in cybersecurity, threat intelligence, or related domains. Familiarity with AI/agentic application patterns. Experience with graph and NoSQL databases. - Startup or small-team experience. Never Stop Dreaming... If you think this role doesn't fully match your skills but are eager to grow and break glass ceilings, we’d love to hear from you!
