QA Engineer (VoIP)

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!
