About the role
- 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.
Responsibilities
- Detection engineering research. Where public detection research is thin or nonexistent, develop detection strategies from scratch for high-blast-radius technologies, crown-jewel systems, and areas of high risk or exposure.
- Adversary emulation. Design and recreate real attacks to test and validate detections and controls. Use the outcomes to improve detections and tooling in customer environments.
Requirements
- 7+ years in offensive security, detection engineering, or a blend of the two, with hands-on purple team or adversary emulation experience.
- Experience with emulation and purple team tooling (Caldera, Atomic Red Team, Prelude, Scythe, or similar).
- Strong red-side skills: adversary tradecraft, command and control, evasion, and building emulation plans that reflect how real intrusions unfold.
- Strong blue-side skills: writing and tuning detections and analyzing endpoint, network, and cloud telemetry in a SIEM or EDR.
- Own the purple team at an MDR company, working directly with adversary research, detection engineering, and the SOC to prove and improve how well we detect real attacks.
- Collaborate with a talented and innovative team focused on continuously improving security operations.
Skills
- Ability to measure detection effectiveness and communicate results clearly to engineers, analysts, and leadership.
- Experience in an MDR/MSSP or high-growth startup environment.
- Detection content development or threat-hunting background.
- Bachelor's degree in Computer Science, Cybersecurity, or Engineering, or a related field (or equivalent experience).
- Relevant certifications such as OSCP, OSEP, CRTO, GIAC (GPEN, GCFA, or GCDA), or CISSP are a plus.
- Competitive salary and benefits package.
- A culture of growth and development, with opportunities to expand your knowledge in AI, cybersecurity, and emerging technologies.
- Strong blue-side
- writing and tuning detections and analyzing endpoint, network, and cloud telemetry in a SIEM or EDR.
- WHY JOIN US?
Compensation
- Competitive salary and benefits package.
Benefits
- Find where coverage falls short, research and design detection use-cases to close it, and validate through testing where that is merited.
Company info
- Backed by leading investors, we are rapidly growing and seeking top talent to join our mission of revolutionizing the AI-Native MDR landscape.
- As an early employee, you'll play a meaningful role in defining and building our culture.
- TENEX runs an Adversary Research Team that studies how real attackers operate and turns that into stronger detection and response for our customers.
- Adversary research. Track the actors, malware, and tooling active against our customers' verticals, and dissect their tradecraft down to the behaviors that matter for detection and emulation.
- Track and report results. Develop reporting that gives leadership and customers a straight answer on where our defenses stand.
