Sales Manager (founding team)

Nebula Security is a Y Combinator-backed cybersecurity company founded by four elite 'hackers' who find the vulnerabilities others miss, and patch them (https://www.ycombinator.com/companies/nebusec). The company has moved quickly from launch, quickly winning support from the Linux community and earning hundreds of thousands in ARR & Bug Bounties, including a recent $250,000 payment from Google for finding a vulnerability in Chrome.

This is a hunter role with a technical edge: you'll prospect like a BDR, run the full cycle and close like an AE, and demo and drive technical wins like an SE. This role reports directly to the Co-founder & CEO and is the company's founding go-to-market hire. You will partner with the Founders and strategic advisors to bring in new business, win deals, and push them to close.

The Sales Manager will be a critical team member with a direct impact on the trajectory and future growth of the company. Seed stage, Y Combinator (S26).

Requirements

\n
• Experience in a customer-facing technical role at a B2B SaaS company, ideally in cybersecurity. Startup experience preferred.
\n
• An unquenchable desire to win as a team — remaining flexible, collaborative, and resilient through ambiguity and high-pressure phases of evolution and growth.
\n
• Must be technical and curious enough to learn new concepts quickly and translate them across all technical literacy levels.
\n
• Ability to lead technical discussions, discovery calls, and demos in partnership with — and eventually in place of — the Founders.
\n

Responsibilities

\n
• Become a subject matter expert on the problem space, competitive landscape, and our product.
\n
• Own new-business revenue end to end: source, qualify, run, and close deals in partnership with the Founders and go-to-market strategic advisors.
\n
• Drive new pipeline through outbound prospecting. Develop and prioritize target account lists, research security and IT organizations, and execute multi-channel outreach to consistently generate qualified first meetings.
\n
• Ensure productive customer interactions by asking and answering insightful technical questions, filling knowledge gaps, and translating win/loss, objections, and buyer insight into actionable feedback for the Founders, Engineering, and Product.
\n
• Guide customers through setup, monitor progress, and ensure successful outcomes and technical wins.
\n
• Turn founder-led wins into a repeatable motion: manage the CRM and build sales collateral, playbooks, demo scripts, technical one-pagers, and FAQ documents that help prospects understand our platform.
\n
• Represent the company at webinars, events, and conferences such as RSAC, Black Hat, and BSides.
\n
• Participate in the overall GTM buildout — hiring plans, process, tooling, and partnerships — as the company scales.
