Founding Engineer, Applied AI Platform

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.
