About the role
Every enterprise wants to adopt AI. The ones that can't move are in the industries that matter most: healthcare, finance, insurance, law, manufacturing. They can't safely deploy AI they don't understand, so they stall.
We fix that. PromptArmor is the comprehensive AI risk platform, sitting at the intersection of the two biggest initiatives in enterprise tech: AI adoption and cybersecurity. We help Fortune 50 companies understand the risk of every third-party AI vendor they touch, put the right controls in place, and continuously mitigate that risk as those systems change, so they can adopt AI faster and with confidence. Backed by Y Combinator and Liquid 2 Ventures, scaled to millions in recurring revenue quickly, and already trusted across the Fortune 50 and a large share of the world's biggest law firms.
Role Overview
You'll be a founding engineer building the platform end to end for real enterprise customers, not prototypes. You'll own products from 0 to 1 with full autonomy over the outcome, architect the LLM systems and data models underneath them, and work directly with go-to-market and customers without a translation layer in between. We're a senior team of 12 growing to 20, and we measure output and ownership, not hours. If you love shipping fast, owning the whole problem, and seeing your work land in customers' hands quickly, you'll feel at home here.
What You'll Do
Build LLM systems end to end. Architect and ship agentic workflows and RAG pipelines in production for external enterprise customers.
Own the data layer. Design the relational schemas and scalable pipelines the platform runs on.
Take products 0 to 1. Own features and products outright, with full autonomy over driving the outcome.
Work directly with customers. Collaborate with go-to-market and get on customer calls when it moves the product forward, no translation layer required.
Iterate on real feedback. Turn what Fortune 50 accounts tell us into fast, continuous improvements to the platform.
About Promptarmor
PromptArmor is an AI risk platform that helps enterprises in the most security-sensitive industries adopt AI without stalling on security review. It assesses the risk of every AI vendor or tool a company is buying or building, tells them which controls to put in place, and keeps monitoring those vendors as they change. Customers include Fortune 50 companies, trillion-dollar model labs, and a large share of the world's biggest law firms.
The team is 12 people building in-person in San Francisco, founded by two UC Berkeley alumni — a CTO who worked on security and infrastructure at Roblox and Google and previously sold a startup, and a CEO who shipped the first AI product at a 250-person Series B. Engineers own products end to end and talk to customers directly
