Job description

Base pay range

$200,000.00/yr - $200,000.00/yr

Overview

We are looking for a Software Engineer who gets excited about building AI agents that break into systems (legally). You\'ll be crafting the core of our agentic red teaming platform, think autonomous systems that discover vulnerabilities while you sleep. This isn\'t your typical engineering role where you\'re handed specs and told what to build. You\'ll make critical technical decisions, ship fast, and directly shape how AI transforms security testing.

What You\'ll Actually Do
  • Build agent systems: Design and implement autonomous agents that conduct security assessments.
  • Ship with autonomy: Own features from conception to production without someone looking over your shoulder.
  • Make smart tradeoffs: Balance speed and scalability in a startup environment where perfect is the enemy of shipped.
  • Collaborate cross-functionally: Work directly with security engineers and customers to turn ambitious ideas into reality.
  • Write TypeScript without any: Build robust, maintainable systems that can handle the chaos of autonomous security testing.
  • Learn security on the fly: You don\'t need to be a security expert, but you should be pumped about learning how hackers think.
  • Communicate clearly: Explain complex technical decisions to teammates and write documentation that actually helps.
What We\'re Looking For

Must-Haves

  • Strong TypeScript experience: You know the language deeply and can architect complex systems with it.
  • Agent building experience: You\'ve built autonomous systems, agents, or similar smart software that makes decisions independently.
  • Cloud native experience: You\'ve built on cloud services and know distributed systems.
  • Security-minded: You have basic understanding of cybersecurity concepts (or genuine excitement to learn them).
  • Self-directed execution: You see problems and fix them without waiting for permission or detailed instructions.
  • Collaborative mindset: You actively seek input from others and make the team better.
  • Excellent communication: You write clearly, explain complex ideas simply, and aren\'t afraid to overcommunicate.
  • Startup-ready: You thrive in ambiguity, make decisions with incomplete information, and adapt quickly.
  • AI optimism: You believe AI will fundamentally change software and want to be part of making that happen.

Nice-to-Have

  • Track record of shipping products in fast-paced environments.
  • Open source contributions or side projects showing your passion.
What We Offer
  • Remote-first: Work from anywhere in the US
  • Compensation:
    • Base salary: $200,000
    • Meaningful equity (we\'re early enough that it actually matters)
  • Actual impact: Your code will directly shape how companies approach security
  • Learning opportunities: Conference budget, books, courses, whatever helps you grow
  • Modern stack: TypeScript, cutting-edge AI tools, and whatever else gets the job done
  • Smart colleagues: Work with people who are genuinely excited about this space. 80% of us are ex-AWS and have shipped products for millions of developers.
Our Mission

We\'re making all software effortlessly secure by building AI agents that think like attackers. This isn\'t incremental improvement – it\'s a fundamental shift in how security testing works. If you\'re excited about building autonomous systems that can outsmart traditional security tools, we should talk.

Interview Process
  • Quick chat with a founder (30 minutes) - We\'ll talk about your experience with agents and what excites you about this space
  • Technical discussion (45 minutes) - Show us something you\'ve built and walk us through your decisions
  • Paid work trial (1 week) - Work on a real problem with the team and see if we\'re a mutual fit
Seniority level
  • Entry level
Employment type
  • Full-time
Job function
  • Engineering and Information Technology
  • Industries: Data Security Software Products
