Job description

Your role
As a Sr. 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 that features work as expected. You build the instrumentation that makes non-deterministic AI behavior testable in the first place. Most importantly, you own product and feature quality 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.
