Software Engineer, Test & Infrastructure

Overview

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.

The base salary range provided is determined by market data matched to the job description and the level of the position, based in our industry and the Chicagoland area. We often consider candidates who do not meet all the qualifications listed in the job description (i.e., more or less years of experience, etc.). Therefore, an offer for this position may differ from the base salary range provided depending on the qualifications/skills of the candidate.

In this case, an updated pay scale would be provided.

At Vail, we believe in the unique power of voice interactions to create more expressive, more intimate, and more efficient interpersonal interactions. Using Vail technology, we make millions of voice interactions better every day.
