## Description

As a Software Engineer at Hadrian, you will design and implement high-performance backend services and distributed systems that power our offensive security platform. You will work on autonomous systems capable of scanning, analyzing, and validating vulnerabilities at internet scale, moving beyond traditional scanning into intelligent, agentic security operations.

This role is ideal for engineers who combine deep backend engineering expertise with a hacker mindset. We're looking for someone who enjoys solving complex scalability challenges, building resilient event-driven architectures, and thinking like an attacker to anticipate edge cases before they happen.

If you enjoy working across disciplines to build autonomous security systems that operate at internet scale, and want to help push offensive security beyond human speed and capability, we would love to hear from you!

What you will do as a Software Engineer at Hadrian:

 * Develop and maintain event-driven components that orchestrate and execute core offensive security strategies.
 * Translate offensive security strategies into robust, high-quality code.
 * Architect and deploy backend services that power our Agentic AI capabilities, moving beyond simple scanning to intelligent, multi-step exploit validation.
 * Write low-level, high-concurrency tools in Go and Python while maintaining robust, scalable APIs.
 * Design data pipelines capable of handling massive internet-wide reconnaissance data using Apache Kafka and Kubernetes/KNative.
 * Leverage your expertise to shape architectural decisions and align technical strategies with business goals.
 * Take on a unique challenge. We're on a mission to uncover the most urgent security flaws in our customers' attack surfaces in real-time. You'll help us build our innovative platform, operating at an internet-wide scale.
