About the role

What will you do at Vail Systems Inc.?

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.

As a Software Engineer, Test & Infrastructure II, you will be doing both English

and Spanish QA testing of call flows and writing automated test cases.

Please note: to be considered for this position, you must be fluent in English

and Spanish.

What You’ll Do

  • * Design and Extend Automation Frameworks: Build maintainable, modular test
  • infrastructure in Python, Perl, Java, or Ruby that adapts to evolving APIs
