DISQO is hiring a Senior Security Engineer to take definitive ownership of our comprehensive security posture, encompassing both AWS cloud and endpoint security. This critical role leads day-to-day security operations across our platform, which includes a high-throughput AWS environment that processes billions of measurement signals. We rely heavily on AI-assisted tooling to enable a small, effective security team.

This is a hands-on individual contributor role. You will harden our AWS footprint, run detection and incident response, and build automations that turn repetitive security work into code. You will be expected to use AI coding agents (Claude Code, Cursor, or similar) as part of your default workflow.

You will report to the Director of Platform and partner closely with Engineering, IT, Product, and Legal. No direct reports. You influence through designs, code, reviews, and the systems you ship.

As Senior Security Engineer, you are the technical owner of DISQO's security posture, encompassing both cloud and endpoint environments. You set the technical bar for security and security operations, driving the implementation of Zero Trust principles across our infrastructure and employee devices. On the cloud side, you own AWS identity, network, data, and account-level controls. On the operations side, you manage detection engineering, alert triage, incident response, and vulnerability management. As an AI-enabled engineer, you leverage coding agents and automation to build tools, agents, and integrations that compress manual toil into seconds, scaling the security practice.

You will work with autonomy on cross-functional initiatives, drive architectural decisions for security-critical systems, and help build a forward-leaning, AI-native security practice.
