About Echo

Echo delivers frontier-hardened software across the enterprise software supply chain.

Echo's containers, libraries, OS packages, VMs, and more are built and patched from source by agentic pipelines, and continuously vetted for supply chain threats. With us, developers and agents can build with secure-by-default software that's compatible with the tools and versions they already use.

We're looking for an AI Engineer to join our team and build the AI agents that build, patch, and secure Echo's artifacts at scale.

What you'll do

Architect and develop autonomous AI agents that build, patch, and validate Echo's artifacts (containers, libraries, and VMs), eliminating vulnerabilities at scale

Build the agents behind Echo Frontier, our vulnerability research product, using frontier models to find, validate, patch, and disclose vulnerabilities

Lead some of our biggest initiatives: explore and prototype cutting-edge AI techniques to tackle our hardest challenges, and bring them from concept to production with product and engineering teams

Monitor and evaluate our AI systems, with feedback loops that continuously improve accuracy, reliability, and performance at enterprise scale
