Senior Product Manager (Cybersecurity) at Nebulock

Nebulock builds hunt-first, behavior-first security operations. Enterprise security teams use their platform to detect attackers inside environments by identifying abnormal behavior, rather than relying on known attack signatures. Attackers frequently change tools, but altering behavior is harder.

Series A company with $34M in funding led by FirstMark, backed by Bain Capital Ventures, Decibel, Zetta, Step Function, and In-Q-Tel. Founding team includes veterans from CrowdStrike, Palo Alto Networks, and Arctic Wolf.

The platform operates as a closed loop:

• A per-customer behavioral system of record that learns what normal behavior looks like in a specific environment, improving accuracy over time.
• Detections built from contextual data, re-baselined as environments shift, maintained by a dedicated detection engineering team rather than static, shipped solutions.
• Autonomous hunting agents that operate from hypotheses rather than alerts, writing detections upon establishing root cause.
• Detection engineering agents that leverage threat hunt context to build, test, validate, and deploy behavioral detections for customers.

Position Overview

This role is ideal for a cybersecurity practitioner turned product leader. As a Senior Product Manager, you will report to the Head of Product and own significant, ambiguous problem spaces from discovery to delivery. Key focus areas include:

• Zero-to-one discovery: Engage directly with SOC analysts, detection engineers, and threat hunters to identify what to build next. Validate problems before development, eliminate unviable ideas, and convert market signals into sharp product decisions.
• Execution with R&D: Ensure discoveries translate into actionable epics with clear success criteria. Collaborate daily with engineering and research to maintain high velocity and deliver products to customers quickly.

Expected Impact

In a year, you will have shipped products that measurably improve security outcomes and strengthen customers' security posture using modern, agentic methods.

Nebulock is an AI-native company, but AI is not an end in itself. The company focuses on automating, reasoning, and delivering autonomous security outcomes. Your products will embody this philosophy, moving customers away from traditional SIEM systems toward hunt-first operations. Your discoveries will shape future bets, and R&D will highlight your epics as pivotal.

Qualifications

• Deep cybersecurity knowledge. Hands-on experience in SOC, incident response (IR), or threat research roles. Ability to discuss detection logic, attacker tradecraft, and the value of hunt hypotheses.
• Solid product management skills. Experience writing epics and stories, defining success criteria, and collaborating closely with R&D. Skilled in running discovery and translating findings into buildable solutions.
• A shipping track record. Prior experience as a product manager with a history of shipping meaningful products and learning from failures.
• Comfort with speed and ambiguity. Ability to thrive in a fast-moving Series A company, often structuring problems that haven't been clearly defined yet.
