Team Cymru’s mission is clear — to save and improve human lives through threat intelligence. 

We’re looking for a Senior AI Engineer to join our growing AI Engineering team and help shape the next generation of cybersecurity innovation.

You’ll work on cutting-edge AI initiatives that leverage our Pure Signal™ platform — the largest source of real-time, external threat intelligence with unmatched global visibility. Our petabyte-scale data ocean delivers insights at speeds others can’t match, empowering security teams to detect and prevent cyber threats worldwide.

Projects may include building Model Context Protocol (MCP) servers, fine-tuning models for domain-specific applications, and developing autonomous AI workflows. This is a hands-on, high-impact role where you’ll build and deploy production code, innovate quickly, and collaborate with a world-class engineering team.

What You’ll Do

• Build AI-powered solutions using technologies like embedding systems and vector databases.
• Manage large and complex data challenges, including handling API responses that exceed LLM context windows.
• Implement evaluation frameworks and monitoring systems to ensure AI reliability and performance in production.
• Design and orchestrate multi-agent workflows with robust tool use, memory systems, and observability.
• Write production-quality Python and Golang code with thorough testing, monitoring, and documentation.
• Rapidly prototype and iterate on new AI capabilities with a small, agile team.
• Stay current with AI/LLM developments and help evaluate new innovations.
• Work with diverse data structures, including graph-based features and vector embeddings.
• Optimize AI systems for cost, performance, and security.
• Adapt to evolving project requirements as our AI strategy grows.
