About Qartaj

Founded by people who were tired of choosing between fast and secure.

We're a small Tunis-based security and software team, working out of one office in Les Berges du Lac.

Qartaj was founded in Tunis in 2019 by a small group of security engineers and developers who were tired of choosing between "fast" and "secure." We're a small team working on security monitoring and product engineering out of the same office.

We work with a growing group of clients across banking, telecom, and other sectors in Tunisia — securing infrastructure, testing applications, and building the software they run their business on.

Interns sit next to the people shipping code and watching the alerts, not next to a slideshow about them. Every track ends with a real deliverable: a hardened service, a triaged incident log, a shipped feature.

How we got here

A short history.

2026

Growing our monitoring desk

Our monitoring work now covers clients across banking and telecom, with a rebuilt detection pipeline aimed at cutting triage time and noise.

2023

Product team opens alongside the SOC

We started building and operating the software our clients run their business on, not just defending it — a small full-stack team working alongside the analysts.

2021

First internship cohort

A small first cohort, one track. Some of them are still on the team today.

2019

Qartaj founded in Les Berges du Lac

Four founders, one client, and a conviction that security and shipping speed shouldn't be a trade-off.

What we value

How we work, in four rules.

01

Ship the fix, not the slide deck

Every audit and every internship ends in something deployed, not a report nobody reads.

02

Whoever's on call, decides

Analysts who triage incidents also write the detection rules — no hand-off between watching and fixing.

03

Say the boring part out loud

Migrations, releases, and incident reports are written so the least senior person on the desk can act on them.

04

Hire from the bench

Strong interns are considered for the team first. We'd rather grow into a role than post another job listing.

Leadership

The desk leads you'd work alongside.

YB

Yassine Ben Salah

Co-founder & CEO

Former incident responder for a regional telecom; started Qartaj to make that skill set a career path in Tunis.

MK

Mariem Kallel

Head of SOC

Runs the monitoring desk and the detection-engineering backlog; the person interns triage alerts alongside.

AH

Amine Haddad

Head of Engineering

Leads the product studio's web and mobile squads, and reviews every intern's first shipped feature personally.

SR

Sarra Rekik

Head of Cloud & DevSecOps

Owns the CI/CD and infrastructure practice, and the runbooks that make our migrations boring on purpose.
