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.

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're 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!
