Software Engineer, Test & Infrastructure I

Who You Are You catch problems before they explode—testing edge cases and degraded paths others overlook so production fire drills can be prevented. You care deeply about the tools you use and create, shaping the internal frameworks and pipelines your team depends on. Your work validates millions of real-time customer interactions every day, from web to telephony platforms, and you’re always growing through peer reviews, knowledge sharing, and mentoring. You thrive in flexible, human-centered environments where hybrid collaboration and sustainable engineering aren’t just buzzwords, but the way you work.  If you love building robust, high-throughput test platforms as much as we do, we’d love to hear from you!  At Vail, our QA Engineering team is deeply technical — we don’t just validate features, we build the frameworks and infrastructure that test real-world signaling flows, analyze media quality, and run performance tests that mimic millions of live voice and web sessions. We're engineers at heart, with a QA-first mindset and a passion for building robust, scalable systems that reveal issues before our customers do. 

What You'll Do

• Develop & Maintain Automation: Write clean, modular, and data-driven test code that adapts to evolving APIs and features, helping reduce flakiness and brittleness in automation.
• Contribute to Test Frameworks: Assist in building and enhancing frameworks that validate complex systems, including telecom protocols, APIs, and media flows.
• Hands-On Testing: Participate in functional, regression, and integration testing across distributed environments—learning how to analyze failures and reproduce tricky edge cases.
