Business Developer

Location: Hybrid (at least 3 days per week at the office)
Employment: Full-time
Team: Business Development

We’re growing quickly and are looking for a Business Developer to join our team. In this commercial role, you help clients identify the security solutions that best fit their needs and spot new opportunities to support their long-term resilience.

About DEFION Security

DEFION started in 2005 as a group of friends. And you can still feel that as soon as you step into our offices. We're a bunch of super-social nerds. How we describe ourselves? Personable, enthusiastic and down-to-earth. New colleagues quickly feel at home with us (especially if they are up for a party and a good joke every now and then).

What you will be doing

• You introduce our Active Defense services to both new and existing clients, helping them understand where DEFION creates real value.

• You act as the key account manager for a selection of clients, building long-term relationships they can rely on.

• You uncover the specific needs of prospects and translate those into the right security solutions. You understand their risk profile and know which of our Managed Services truly fits.

• You bring a genuine hunter mentality — spotting opportunities, opening doors, and driving conversations forward.

• You collaborate closely with our business units (Prevent, Detect, Respond, and Governance) to craft the best-fit IT security solutions.

• You get excited about ambitious — but achievable — goals, and you work hand in hand with the commercial team to make them happen.

• You prepare high-quality proposals that are clear, compelling, and aligned with client expectations.

• You take initiative when something needs to be organized — workshops, lunches, master classes — you make sure clients feel engaged and supported.

• You enjoy attending industry events and know exactly which ones deserve a spot on your agenda.

What you’ll get...

• A good salary that matches your experience and an appealing bonus scheme.
• A lease car of your choice.
• A good smartphone and laptop.
• Flexible (home) working hours.
• A one-year contract (if we are both enthusiastic after a year, you will receive a permanent contract).
• We are growing fast, so it makes sense that you want to grow with us. Do you want to develop further in your role? Then we will look at the possibilities together.
• A lavish daily lunch buffet, made with love.
• Great parties, team outings, monthly get-togethers and study trips.

This is you:

• Proactive. Ready to seize opportunities and explore new ones.
• A sociable type who everyone finds it easy to get along with.
• Curious. News about cybersecurity? Of course you're already aware.
• A committed colleague who creates a positive atmosphere.

This is what you've got to offer:

• A university or university of applied sciences degree.
• Work experience in (cybersecurity) sales.
• Familiar with MDR, SIEM and Endpoint Security? That's a bonus!
• Broad knowledge of cybersecurity is also useful.
• A smooth talker (both in Dutch and English).
• A lot of empathy (useful for customers AND colleagues 😉).
