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 Senior+ Infrastructure Engineer to help build a secure, reliable, cost-effective, and agent-forward foundation for running Cogent's products and services.
You'll join a small, fast-growing Core Platform pod (that includes infrastructure, security, and compliance) and work hands-on across our data platform, our security systems, and the platform layer our agents use to build and ship the product. Ultimately you'll help keep the company, our customers, and our employees protected against external and internal threats. This is an early-stage, high-ownership role for an engineer who has built core infrastructure at startup scale and can operate across many stakeholders.
