Sr. Software Development Engineer in Test Job at Dialpad (Kitchener)

Job Description

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.

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

Hands-on exposure to LLMs or AI/ML systems (e.g., OpenAI, Claude, Gemini, or similar platforms)
Understanding of non-deterministic systems and probabilistic testing approaches
Experience building test frameworks and scalable automation systems
Familiarity with AI evaluation techniques (benchmarking, golden datasets, human-in-the-loop validation)
Experience with CI/CD pipelines (e.g., Jenkins, GitHub Actions)
Strong collaboration skills with the ability to work across distributed teams and time zones
Bachelor’s degree in Computer Science or equivalent practical experience
