Summary 

As a Senior AI Engineer, you will be a key architect of the systems that power our AI-driven security swarm. We are looking for a high-impact engineer who can build production-grade systems that are as robust as they are innovative. You will work at the intersection of cybersecurity and generative AI, turning complex security logic into a seamless, scalable product.

What You’ll Do

• Partner with security researchers and AI engineers to turn cutting-edge findings into automated product features
• Design and ship AI-native features - agents, tool calling, RAG, and eval loops - from idea through production, monitoring, and iteration
• Turn ambiguous product problems into working solutions; learn fast from real usage and feedback
• Work closely with product and engineering to ship together efficiently

• 6+ years backend engineering; owns and ships production systems end-to-end
• Deep hands-on experience with TypeScript, Node.js, and React
• Builds AI-native features - agents, tool calling, RAG, and eval loops
• Self-starter who thrives in ambiguity; takes problems from idea to production with little oversight
• Creative problem solver who moves fast without sacrificing quality
• Collaborative teammate who partners closely across functions and helps the team move faster together

Advantage

• A background in cybersecurity, application security, or red/blue teaming.
• Hands-on experience with cloud environments (AWS/GCP), including Docker, Kubernetes, MongoDB, and scaling distributed systems.
• Experience working with Large Language Models (LLMs) and generative AI workflows.
• Prior experience in early-stage, high-growth startups.
• BA/B.Sc. in Computer Science or a related technical field.
