What We're Looking For We’re looking for an experienced backend engineer to build and scale an automated system to manage a variety of Security Analyst tasks. We aim to verify and neutralize threats in minutes using AI-driven automation. A few examples of the work we’ve done recently:

• Built a sophisticated LLM engine to reduce verification workloads by 4x for the highest volume product line, which will enable faster takedowns at scale
• Built a QA & data labeling tool to close the feedback loop with human analysts, ML models, and LLM agents

As part of our SF team (in-office min 3x/week), you’ll:

• Play a critical role in building systems that protect billions of people from AI-generated scams and general digital harm
• Have complete end to end ownership - from directly collecting product requirements to continuously evaluating and iterating on shipped releases
• Mentor junior engineers, foster a high-performing team culture, and shape the team roadmap
• Enjoy monthly in-person dinners, happy hours, and social activities (Exploratorium, Valkyries game, etc.)
