Company Overview:
TENEX is an AI-native, automation-first, built-for-scale Managed Detection and Response (MDR) provider. We are a force multiplier for defenders, helping organizations enhance their cybersecurity posture through advanced threat detection, rapid response, and continuous protection. Our team is composed of industry experts with deep experience in cybersecurity, automation and AI-driven solutions. Backed by leading investors, we are rapidly growing and seeking top talent to join our mission of revolutionizing the AI-Native MDR landscape.
We’re a fast growing startup backed by industry experts and top tier investors led by Crosspoint Capital Partners and also backed by Shield Capital, DTCP (formerly Deutsche Telekom Capital Partners), Deepwork Capital, and the Florida Opportunity Fund. Seed round led by Andreessen Horowitz (a16z). As an early employee, you’ll play a meaningful role in defining and building our culture. Get in on the ground floor. We’re a small but well-funded team that just raised a substantial round – joining now comes with limited risk and unlimited upside.

About the Opportunity:
TENEX is changing how MDR is delivered, and incident response is where that shows up most. As a Senior Incident Responder, you’ll be at the sharp end of our service — leading investigations, containing active threats, and guiding customers through their hardest security moments. You’ll own escalations end to end, shape how we respond as we grow, and build the track record to step into IR leadership as the team scales.
What You’ll Do:
-
Lead incident investigations. Own complex investigations from detection through containment, eradication, and recovery.
-
Drive customer response. Act as a strategic advisor to clients through active incidents as a calm, credible technical lead.
-
Improve response playbooks. Turn lessons from real incidents into better detections and repeatable response procedures.
-
Design and build data collection and preservation toolkit. Work with engineering to automate key processes in the TENEX platform, ensuring reliability and non-repudiation.
