We’re building the Insurer for the Agent Economy. Mount (YC P26) enables safe industry-wide adoption of AI systems, agents, and autonomous workflows.
We want a sharp, AI-native engineer to own the first version of our underwriting engine. You’ll work across risk modelling, decision logic, internal tooling, and early AI security features that help us understand and price risk for deployed AI systems.
This role is a fit for someone early in their career who is unusually strong. You might be a standout student, recent grad, or young engineer who learns fast, ships fast, and wants real ownership. Mount’s team is an intentionally small collection of people who are excellent at what they’ve joined it for, so you should be too.
What you’ll do:
You should be comfortable going from vague problem to working system, using AI tools heavily and natively, and owning messy, cross-functional work. This is an on-site role with high ownership.
Mount is the Insurer for the Agent Economy.
When AI systems autonomously sign contracts, manage finances, or talk to customers, every failure becomes the deployer's liability. Existing insurers don't want to cover this. They lack the data, the models, and the speed to assess deployed AI systems.
We're solving this by building a risk evaluation and mitigation platform specifically for AI Agents. Mount's platform red-teams them, scores their operational risk, and issues ADR certifications (the SOC 2 for AI agents). Every evaluation generates proprietary risk data that feeds our underwriting engine, a data moat no competitor can replicate.
The AI agent market is projected to grow from $7.6B to $183B by 2033. The EU AI Act and upcoming regulation require deployers to manage AI risk. Over 90% of businesses want coverage for AI risks, yet no insurer is built to price this new risk category. We are that company.
Fabian studied CS at ETH Zürich with a focus on machine learning and has been building AI systems since. John founded an AI-first media company at 18 and scaled it to 400K in annual revenue. Together, they combine deep technical AI expertise with the operational intensity to build a full-stack insurance company from scratch.
