What are the responsibilities and job description for the Founding Account Executive position at Mars Security?
About The Mars Security
Mars Security is an early-stage cybersecurity company building a new category of security technology, backed by deep hands-on experience from offensive security, threat intelligence, and security operations.
We're building a platform that lets security teams run continuous threat hunting and detection engineering across their existing stack. Most SOCs cannot tell you which active campaigns their environment would catch today. Mars closes that gap.
Founded by experienced operators, backed by world-class investors, and working with design partners across financial services, healthcare, pharma, and industrial security. We're building a team of people who thrive on ownership, ambiguity, and impact.
About The Role
Mars Security is looking for a driven, deal-closing Account Executive to join our founding GTM team. This is a high-octane, high-impact role - built for top performers only, with high benefits.
This is not a "spray and pray" sales role. You'll be selling to security leaders who expect depth, credibility, and value in every conversation. You'll work hand-in-hand with the founders, with a direct line to product and leadership - and your feedback will shape how we go to market.
If you've closed deals in cyber before, thrive in a fast-moving startup environment, and want real ownership in a company you're helping build - this is your role.
