Nebulock builds hunt-first, behavior-first security operations. Enterprise security teams use us to find attackers already inside their environment by spotting behavior that's abnormal for that organization, rather than by matching signatures of attacks someone has already seen. Attackers rotate tooling constantly and it costs them almost nothing; changing how they behave is much harder.
Series A, $34M total raised led by FirstMark, with Bain Capital Ventures, Decibel, Zetta, Step Function, and In-Q-Tel. Founding team out of CrowdStrike, Palo Alto Networks, and Arctic Wolf.
The platform is a closed loop:
A per-customer behavioral system of record that learns what normal looks like in a specific environment and gets more useful the longer it runs
Detections built from that context, re-baselining as environments shift, maintained by a detection engineering team rather than shipped and forgotten
Autonomous hunting agents that work from a hypothesis instead of an alert, and write the detection when they establish root cause
Detection engineering agents that take the context of threat hunts run to build, test, validate and deploy behavioral detections for Nebulock customers.
Nebulock is looking for a technical, customer-facing Enterprise Sales Engineer to help drive our next stage of growth. This is an opportunity to join early, shape the technical sales motion, and become a trusted advisor to some of the most sophisticated security teams in the market.
We’re looking for someone who thrives at the intersection of cybersecurity, storytelling, and problem solving. You’ll partner directly with Account Executives to build technical strategy within accounts, guide customers through evaluations, and demonstrate how Nebulock fundamentally changes the way organizations approach threat hunting and detection engineering.
As one of the early SE hires, you’ll play a critical role in influencing product direction, refining messaging, supporting channel partners, and helping define the customer experience from first conversation through deployment. You should be comfortable operating in fast-moving environments, navigating ambiguity, and engaging deeply with both technical practitioners and executive stakeholders.
The ideal candidate combines strong technical depth with commercial awareness. You know how to simplify complex concepts, uncover customer pain points, and translate security telemetry into compelling business value. Most importantly, you bring a builder mentality, low ego, and a genuine excitement for helping create a category-defining company.
