Being a Dialer At Dialpad, AI isn’t just a feature; it’s how our teams do their best work every day. We put powerful AI tools in every employee’s hands so they can move faster, think bigger, and achieve more. We believe every conversation matters. And we’ve built the platform that turns those conversations into insight and action, for our customers and ourselves. We look for people who are intensely curious and hold themselves to a high bar. Our ambition is significant, and achieving it requires a team that operates at the highest level. We seek individuals who embody our core traits: Scrappy, Curious, Optimistic, Persistent, and Empathetic . Your role As a Sr. SDET in Agentic QA, you will own the test automation and quality frameworks that support Dialpad’s AI Voice Agent services. You will develop automated tests for end-to-end product experiences, from frontend UI to backend services to APIs to audio/text interactions. You will test orchestration flows, agent configuration experiences, and guardian safeguards to create robust automated coverage for functionality, performance, reliability, UX, and more. In this role, you will develop substantial amounts of automated test infrastructure and partner deeply with the development team to make our fast-growing AI platform more testable, more stable, and more delightful for customers. This position is based at one of Dialpad’s Canadian offices and reports to a QA Eng Manager in the United States. What you’ll do Own end-to-end quality for agentic features and workflows, including strategy, development, execution, and release qualification. Design and build automation tooling and frameworks for AI/LLM-driven systems, including prompt flows, agent orchestration, and tool integrations. Develop and maintain evaluation frameworks (evals) to measure response quality, accuracy, and hallucination rates. Drive automation coverage (80%+ for critical AI workflows) using deterministic + probabilistic validation approaches. Integrate AI quality checks into CI/CD pipelines with fast feedback cycles (<15 minutes for PR validation). Build tooling for LLM observability and debugging, including prompt tracing and response analysis. Partner with Applied AI teams on prompt engineering, model selection, and evaluation strategies. Design and execute performance and load tests for AI services (latency, throughput, cost efficiency). Identify and mitigate risks related to hallucinations, bias, safety, and edge cases. Define and track AI quality KPIs (task success rates, precision/recall, latency, etc.). Participate in design and architecture reviews to ensure systems are testable, observable, and resilient. Mentor engineers and contribute to raising the bar on AI quality engineering practices. What you’ll bring 5+ years of experience in software engineering or SDET roles with an emphasis on software development. Strong programming skills in Python (preferred), Java, or JavaScript. Experience testing distributed, cloud-native SaaS systems and APIs. Demonstrated proficiency in coding with AI agents to accelerate development and improve code quality. Hands-on exposure to LLMs or AI/ML systems (e.g., OpenAI, Claude, Gemini,
