Job description

ReactiveZero's pipeline should be as sharp as its engagements. As our cybersecurity salesperson you'll own the commercial side of offensive security—penetration testing, red teaming, and the products and services around them, from first conversation to signed engagement.

This is a technical sale to a technical audience: CISOs, security leads, and engineers who can smell a script a mile away. You win by understanding what we actually do and translating it into value, not by reading a pitch deck. Dutch fluency lets you own the Benelux market directly; English is essential for the rest.

Flexible on structure: this works as a freelancer (ZZP) on a percentage of the sales you bring in. We'll shape the arrangement together, one on one, around what fits you best.

What you'll do

• Own the full sales cycle for offensive security services, prospecting, qualifying, scoping, proposal, close.


• Build and grow the Benelux market, selling in Dutch to security and engineering leaders.


• Work hand in hand with pentesters to scope engagements accurately and set honest expectations.


• Develop relationships with CISOs, security teams, and partners — trust compounds in this industry.


• Feed the field back into the offering: what clients need, what they'll pay for, where we should go next.

What we look for

• Experience selling offensive security products or services — pentesting, red teaming, security tooling, or adjacent.


• Dutch speaker strongly preferred; fluent, professional English required.


• Genuinely comfortable in technical conversations — you can hold your own with a security team.


• A consultative, no-BS style: you sell by being useful, not pushy.


• A track record you can point to — deals closed, markets built, relationships that lasted.

Nice to have

• An existing network in the Benelux or wider EU security market.


• Familiarity with how pentests and red-team engagements are scoped and priced.


• Additional languages for the wider European market.
