Title: AI Software Engineer

Location: San Francisco, CA (Onsite)

About the Opportunity

A high-growth AI cybersecurity startup is building next-generation defense systems to combat automated, AI-driven threats. Their platform uses autonomous agents to identify, validate, and remediate vulnerabilities in complex enterprise environments—before attackers can exploit them.


What You’ll Do

  • Build and ship production-grade features across a distributed system
  • Develop and improve AI-driven agent pipelines and ingestion systems
  • Design resilient backend systems with real-world failure handling
  • Contribute across the stack (APIs, infrastructure, data pipelines)
  • Own features end-to-end—from concept to deployment
  • Work directly with leadership and customers to solve complex problems

What We’re Looking For

  • 3–5+ years of software engineering experience
  • Proven track record of shipping complete systems end-to-end
  • Hands-on experience using AI tools (Claude, Codex, Cursor, etc.) in development workflows
  • Strong understanding of distributed systems (retries, idempotency, failure handling)
  • Cloud experience (AWS, GCP, or Azure)
  • High ownership mindset—self-directed and execution-focused

Nice To Have

  • Experience with Temporal or similar distributed workflow systems
  • Background in enterprise SaaS or multi-cloud environments
  • Strong open-source or GitHub presence

Why This Role

This is a true builder role at a company operating at the intersection of AI and cybersecurity. You’ll be part of a small, elite team shipping quickly, solving hard problems, and directly impacting how enterprises defend against next-generation threats.
