Freelance network engineer in Leiden? Find your next assignment via Maedium

Leiden's assignment market revolves around life sciences, biotech, healthcare and research, with the Leiden Bio Science Park as the largest cluster of its kind. These organisations work with sensitive data and critical systems: laboratories, research facilities and healthcare institutions that depend on reliable, secure networks. For you as a freelancer that means assignments in which reliability, segmentation and data protection are central.

If you value working in an environment with societal impact, you'll find meaningful, stable assignments in Leiden. Experience with network security, segmentation of sensitive environments and vendor technology is valuable here. Leiden lies centrally in South Holland and is well accessible from across the region.

What do you earn as a freelance network engineer in Leiden? Your hourly rate depends on your experience, your specialisation and the weight of the assignment. As an indication, excluding VAT:

• Medior: roughly €53–€73 per hour
• Senior: roughly €68–€93 per hour
• Lead / specialist: up to €108+ per hour for scarce profiles

Scarce specialisations — network security, OT networks, large-scale vendor environments (Cisco, Fortinet, Juniper) — sit at the top of the market. In Leiden rates sit around the national average. If you work via Maedium, we agree the rate clearly in advance — you know exactly what you receive per hour, with no surprises.

As an independent professional you want to work without worries — and since the Dutch Tax Authority resumed enforcement on false self-employment, a correct setup matters more than ever. Maedium arranges that for you, in two ways:

• Brokerage. We connect you with the client, after which you contract directly with them. We facilitate the match and, if desired, take over invoicing via factoring. You retain full autonomy as an entrepreneur.
• Intermediation. The contract runs through Maedium: we contract you and the client. Handy for longer assignments or when the client wants extra certainty around the DBA Act. You remain self-employed — no employment, no payroll tax.

Which form fits depends on the assignment and your own preference. We discuss it honestly with you, so you always get to work compliantly and with peace of mind.

Maedium is a specialised brokerage agency for freelance IT specialists in the Randstad. We work with one fixed point of contact — Nick — who genuinely gets to know you: your specialisation, your preferences and the kind of assignment that makes you happy. No anonymous database, but personal contact and honest matches.

Sign up and we'll discuss your profile and your wishes. As soon as a suitable network engineer assignment comes up in Leiden or the surrounding area, we connect you specifically with the client. We broker exclusively in cloud and network specialisms, so you end up with a party that understands your field.

How do I get assignments via Maedium?

You sign up once and we get to know your profile. As soon as there's a suitable assignment in Leiden or the surrounding area, we connect you specifically with the client. You don't have to tout for work yourself — we know the clients.

Do I work via brokerage or intermediation?

Both are possible. With brokerage you contract directly with the client; with intermediation the contract runs through Maedium. Which form fits we discuss per assignment — always DBA-compliant.

Do I have to live in Leiden?

No. Network work more often requires presence on site, but we look at assignments in Leiden and the wider region. Live further away but want to work here? Feel free to sign up and we'll see what's possible.
