Job description

About the team

Dialpad's Contact Center QA team owns the quality of the AI-driven services behind our customer engagement platform. We validate that complex features like AI Routing, Digital Agents, and real-time Analytics are genuinely enterprise-grade in scale, reliability, and performance. And we go further, working cross-functionally and across projects, collaborating closely with developers and product managers to ensure every customer interaction is smooth, responsive, and delightful.

Your role

As a Senior Software Developer in Test (SDET) in the Contact Center QA team, you're both a skilled developer who builds elegant, scalable test frameworks and a quality advocate who leads a team to optimal customer outcomes. You write the API, UI, capacity, security, and performance tests necessary to validate features work as expected. You build the instrumentation that makes non-deterministic AI behavior testable in the first place. Most importantly, you own quality for products and features end-to-end, keeping communications flawless for the banks, hospitals, veterinarians, and other businesses that trust Dialpad with every conversation.

What you'll do

  • Plan and implement functional, regression, and end-to-end tests at the UI, API, and database levels
  • Develop, execute, and analyze test runs for the capacity of microservices and performance of key product scenarios
  • Own the test strategy for Dialpad's latest AI Contact Center systems such as AI Routing, Digital Agent workflows, and Agentic Analytics
  • Leverage agentic coding tools to generate test cases and build test software
  • Provide detailed failure analysis to facilitate speedy product and test fixes
  • Define the KPIs that matter and communicate results across teams and business stakeholders
  • Participate in design discussions and reviews, addressing edge cases and inserting test hooks before development even begins
  • Write reliable, maintainable code and find creative, scalable solutions to hard problems
  • Mentor other engineers while staying on top of test and software development best practices

What you'll bring

  • Relevant software development experience (typically 6+ years), preferably including building test automation frameworks for SaaS applications.
  • Strong programming expertise in any top language, such as Python or Java
  • Strong experience designing and building scalable test automation frameworks
  • Extensive use of AI coding agents for test generation and optimization
  • Polished written and verbal communication skills in English
  • Comfortable communicating cross-functionally and with teams in different geographies
  • Prior experience applying different testing methodologies, including functional, integration, load, and performance testing
  • Deep familiarity with cloud technologies, including the testing of REST services
  • Experience injecting tests in CI pipelines
  • Proficiency in AI-driven evaluation methodologies, eval harnesses for non-deterministic systems, or validating enterprise-scale data infrastructure is helpful

Technologies we use

  • Google Cloud Platform (GCP) including Cloud Run (GCR), Kubernetes (GKE, k8s) and Compute Engine (GCE)
  • Python, Javascript, Go, Vue, GitHub, Qase, Jira
  • Pytest, Playright, REST Assured, Selenium
