Description complète du poste

We’re not looking for someone who just “runs test cases”.

We’re hiring a QA Engineer for our VoIP team who understands that quality in real-time communication is not optional: it’s critical infrastructure. You’ll be working on voice services where milliseconds matter, packets matter, and failures are immediately user-visible.

This is not a checkbox QA role. It’s about owning the reliability of voice communication end-to-end.

We move fast. We expect curiosity, rigor, and the ability to dig into systems when something breaks — not just report it.

What You’ll Be Doing

Own VoIP Quality End-to-End

Design, develop, and execute test strategies for VoIP services across functional, regression, and integration layers.

Validate Real Call Flows

Test full lifecycle scenarios: registration, call setup, call teardown, edge cases, and failure conditions.

Deep Dive into Signaling & Media

Analyze SIP signaling and RTP streams to identify issues affecting call quality, stability, or connectivity.

Investigate Like an Engineer

Use logs, traces, and packet analysis (e.g. Wireshark) to understand root causes — not just symptoms.

Work Cross-Functionally

Collaborate closely with developers, DevOps, and product teams to clarify behavior, reproduce issues, and improve system reliability.

Support Releases & Production Issues

Participate in release validation and help troubleshoot live incidents when needed.

Build Smarter Testing

Contribute to API and service-level test automation to improve speed and coverage.

Own Defect Quality

Log clear, actionable bugs with strong reproduction steps, impact analysis, and technical clarity.

Continuously Improve QA

Push for better test coverage, better tooling, and more efficient QA workflows.

What We’re Looking For

You’ll be a strong fit if you:

Have experience in software testing (manual and/or automation)
Understand VoIP fundamentals (SIP, RTP, call flows)
Can analyze logs and debug complex system issues
Know basic network concepts (TCP/IP, UDP, latency, packet loss)
Have used API testing tools (Postman or similar)
Are comfortable working with Jira or similar tracking tools
Think analytically and care deeply about detail and accuracy
Don’t stop at “what failed”: you dig into why

What Will Set You Apart

Hands-on experience with VoIP systems (PBX, SBC, softswitches)
Strong Wireshark / packet-level debugging skills
Linux command-line familiarity
Test automation experience (Python, Java, or similar)
Exposure to CI/CD environments
Experience in telecom, real-time systems, or high-load platforms

What Success Looks Like

You can independently debug complex VoIP issues
You catch problems before they reach production users
Developers trust your bug reports because they are precise and actionable
Release cycles become faster and more stable because of your work
Test coverage evolves continuously, not statically

Why Join Us?

Work on real-time voice systems where reliability is everything
Deep dive into VoIP and telecom engineering at scale
Strong engineering culture where QA is a core part of product quality
Real ownership over testing strategy, tools, and processes
Direct impact on user experience: every call matters

If you’re the kind of QA Engineer who doesn’t just test features but breaks systems to make them stronger, we should talk!
