About Cogent
Cogent is an Applied AI Lab building the next generation of AI agents for cybersecurity. AI has fundamentally changed how attacks happen, allowing malicious actors to operate at unprecedented speed and scale. Cogent's "AI Taskforce" assesses petabytes of enterprise data to remediate these issues before critical breaches occur.
To stay at the cutting edge, we blend frontier research with real-world execution. Alongside our core product work, Cogent Research serves as our applied AI lab, providing the research horsepower needed to make truly agentic security workflows a reality. We partner with Fortune 500 companies to secure some of the most complex production environments in the world.
We're backed by Greylock & Bain Capital Ventures, and we've built a team with the best minds in applied AI. Our team is comprised of people from:
Top universities like Stanford, Berkeley, Penn, Duke, Carnegie Mellon, Waterloo
Unicorn, high-growth companies like Scale AI, Databricks, Stripe, Tesla, Coinbase
World class cybersecurity experts from Wiz, Abnormal AI, Zscaler
Preeminent research labs like Deepmind and SAIL
About the Role
We're hiring a Developer Experience Engineer on our Core Platform team to own the software delivery lifecycle - the build, CI/CD, and provisioning systems that let both engineers and agents ship securely and fast. You'll build the systems that take code from idea to production, including the infrastructure that lets agents build, deploy, test, and verify autonomously.
This is a hands-on role for someone who has built developer and delivery infrastructure at an AI or high-growth startup and wants to define how autonomous agents move code to production.
What You'll Do
Build an agent development experience that streamlines idea to production, letting agents build, deploy, test, and verify code autonomously
Build a self-hosted software builder, a secure GitHub Actions Runner alternative that meets our compliance requirements
Adopt and operate a solution to provision infrastructure securely
What We're Looking For
Deep experience with CI/CD and build systems: GitHub Actions, Harness, Spacelift
Strong infrastructure-as-code skills with Terraform
Comfort working in an agent-forward environment with Claude Code and Codex
2-4 years at an AI startup, plus 2-4 years at a successful high-growth tech company
Bonus Points
Self-hosting experience across GitHub and ECR
Build tooling experience: Pants, uv, e2b, pico
Artifactory
Prior startup founder experience
A secondary spike in Application Security
For California Based Applicants
