About this role
About the Role
We're 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. If you've built agents before, you know how wild this space can be
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
