Summary 

As a Senior Software 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

• Design and build scalable, production-grade backend and frontend systems that support our autonomous AI agents.
• Work closely with security researchers and AI engineers to translate cutting-edge security findings into automated product features.
• Own entire features and complex projects from initial ideation and technical design to deployment and monitoring.
• Shape our long-term architecture and tech stack choices, maintaining a high bar for code quality and engineering culture in a fast-paced environment.
• Tackle "zero-to-one" challenges as we evolve our platform to handle increasingly complex enterprise environments.

Requirements

• 6+ years of professional experience in fullstack software development, ideally within high-growth environments.
• Deep hands-on expertise with TypeScript, Node.js, and React.
• You are a self-starter and creative problem solver who thrives under ambiguity and delivers high-quality results quickly.
• Strong teamwork and communication skills, with the ability to explain complex technical trade-offs to both technical and non-technical stakeholders.
• A strong commitment to quality first, with rigorous self-driven QA to ensure high standards in both code and final outputs. 

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.
