Compensation

$220k–$300k base + 0.1–0.3% equity

About the company

Our client is an AI-powered cybersecurity platform that protects businesses from account takeovers, specifically targeting Microsoft 365 environments — the kind of business email compromise attacks that have exploded 141% year over year. They went from first customer to mid-seven-figures ARR in under a year with just four engineers, protect 1.6M+ users across 10,000+ businesses today, and win 90%+ of head-to-head competitions. Founded by security-industry alumni, backed by top investors, and still priced like a seed-stage company despite the growth — real early-stage upside with proven product-market fit.

The role

A front-end-leaning engineer on a small, high-output team building customer-facing product for MSPs and security teams. You'll ship delightful, high-quality software that real customers use daily, and have real design taste and ownership over huge parts of the product.

What you'll do

Own and ship large, customer-facing product features end-to-end — from design through production
Build beautiful, high-quality front-end experiences in React and TypeScript
Drive product quality by understanding what customers care about and translating that into shipped software
Architect scalable solutions as the platform grows 10x from its current customer base
Help build a new product line leveraging the company's unique data advantage
