Commercial Account Executive (East & West)

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 highly driven, entrepreneurial Commercial Account Executive to build and own a high-velocity book of business from the ground up. We're looking for a hunter who thrives on volume, speed, and creating momentum across a broad set of accounts.
As one of the early sales hires, you'll operate as the CEO of your patch, responsible for running a full-cycle sales motion from prospecting and pipeline generation through negotiation and close across mid-market and commercial-segment accounts.

You'll partner closely with Sales Engineering, Marketing, and Leadership to shape how Nebulock scales in this segment. The ideal candidate is energized by a fast-paced environment, obsessed with winning, and motivated by the opportunity to help define the future of AI-driven cybersecurity. You know how to run efficient, high-volume sales cycles, build trust quickly with security and IT leaders, and juggle a growing pipeline without losing momentum. Most importantly, you bring a low-ego, high-accountability mindset and are excited to help build something category-defining.

• Own and grow a defined book of commercial accounts, operating as the CEO of your patch with full accountability for pipeline and revenue generation

• Run a high-velocity, full-cycle sales process - prospecting, discovery, demo, negotiation, and close across a larger volume of accounts than a typical enterprise motion

• Build repeatable outbound habits to consistently self-source pipeline alongside marketing-generated leads

• Drive sales cycles efficiently, engaging security and IT decision-makers and champions to build urgency and consensus

• Partner closely with Sales Engineering to deliver compelling technical and business value throughout the customer journey

• Collaborate cross-functionally with Marketing, Product, and Leadership to provide market feedback and help shape go-to-market strategy

• 3+ years of experience in full-cycle sales, ideally within cybersecurity or infrastructure technology

• Proven ability to self-source pipeline, run efficient discovery, and close deals with speed

• Comfort managing a high volume of concurrent opportunities without sacrificing quality of execution

• Strong communication and presentation skills, with experience selling to IT and security practitioners and managers

• Ability to adapt quickly, iterate in fast-moving environments, and thrive in ambiguity

• Highly motivated with a strong hunger for growth and achievement

• Team-first mentality with a low-ego, collaborative approach to building a company

• Cybersecurity industry experience

• Startup or early-stage company experience

• Experience selling emerging technologies or security operations solutions

• A dynamic startup environment with opportunities for rapid career growth

• A collaborative culture that values innovation and creativity

• Competitive salary and meaningful equity options

• Comprehensive benefits package, including 401(k)

• Opportunities to travel for conferences, workshops, customer meetings, and team-building events
