Job Description
Career Renew is recruiting for one of its clients a Design Engineer - this is an onsite role in San Francisco. Salary range: 220-300K plus benefits plus equity.
We are an AI-powered cybersecurity platform that protects SMBs from account takeovers, specifically targeting Microsoft 365 environments. Business Email Compromise (BEC) attacks have exploded, rising 141% year-over-year, and have become the #1 way businesses lose money to cyberattacks. Petra detects more attacks and responds faster than any competitor on the market while triggering fewer false positives

  • 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 for MSPs and security teams

  • Drive product quality by understanding what customers care about and translating that into shipped software

  • Architect scalable solutions as the platform grows from 10K+ businesses to 10x that

  • Help build a new product skew for attack prevention, leveraging our unique data moat
