ABOUT PROPHET SECURITY

Prophet Security builds an AI-native security operations platform that accelerates detection, investigation, and response. We help security teams move faster without being constrained by alert volume or fragmented tools. As an early team, you'll work alongside veterans from Abnormal Security, Expel, Mandiant, and McAfee, and help shape what we build as we scale customer outcomes.

WHY THIS ROLE EXISTS

Security operations is being fundamentally reshaped by AI agents. Prophet is building an autonomous AI agent for triaging alerts, investigating incidents, and recommending response actions; to do so, we need to resolve the challenge of ensuring our agent can effectively deliver outcomes in the messy reality of each customer's environment.

You'll be the person who ensures Prophet's agent delivers these outcomes — debugging why a detection missed, figuring out why an integration is dropping events, building a workflow that connects the dots across a customer's security stack. Some days that means writing code. Other days it means getting on a call with a customer's SOC lead to understand why the agent's output isn't matching their expectations — and figuring out whether that's a data problem, a product gap, or both. This is not a support role. This is an engineering role where the customer's environment is your production system.

WHY JOIN AGENT ENGINEERING

You're joining the founding Agent Engineering team. A few reasons this matters:

- Founder-level reps. You'll get reps in product discovery with real customers, shipping under real constraints, and developing the judgment to know when to build vs. push back – this is the same type of experience that helps you build the skillset to become a founder

- AI meets security, in production. You won't be reading about AI agents — you'll be making them work against real threats, in real customer environments

- No game of telephone. You work dir...
