Cambridge, Massachusetts, United States

Third Way Health is hiring a Senior QA Engineer

Responsibilities

  • Lead the development and enhancement of a multi-tiered evaluation pipeline covering tool call validation, risk heuristics, and LLM-based transcript assessment.
  • Improve evaluation methods for full system performance across coordinated agents, RAG-enhanced responses, and multi-party voice interactions using provider-agnostic verification.
  • Enhance observability tools to expose evaluation metrics, identify performance regressions, and support data-informed quality decisions.
  • Develop real-time monitoring systems that detect live interaction issues, apply contextual interventions, and feed insights back into system improvements.
  • Collaborate with machine learning, product, and operations teams to convert real-world failures into automated test cases and strengthen evaluation coverage.
  • Create and manage test suites focused on adversarial scenarios and edge cases, including resistance to prompt injection and behavior under ambiguous user input.
  • Promote early integration of quality standards by embedding evaluation into prompt design, defining behavioral acceptance criteria, and prioritizing quality in development.
  • Help design the orchestration of QA workflows, including background tasks, alerting via Slack, and risk data storage, to boost efficiency and developer usability.

Cross-functional team collaborating with ML engineers, product managers, and operations leads

Responsibilities

  • Own and extend our multi-layered eval pipeline and verification portfolio: deterministic quality checks on tool calls, risk-factor heuristics, and LLM-graded transcript evaluation.
  • Advance our capabilities to evaluate end-to-end system performance (across orchestrated agents, RAG-supported responses, multi-party voice conversations) with modular and auditable verification that is independent of any single model provider.
  • Drive improvements to our observability stack to surface eval metrics, detect regressions, and enable data-driven quality decisions across the team.
  • Build real-time monitoring and verification loops that catch issues in production interactions as they happen, intervening with context and feeding back for system refinement.
  • Partner with ML engineers, product managers, and operations leads to translate real-world failure modes into automated checks, closing the loop between production incidents and eval coverage.
  • Build and maintain adversarial and edge-case test suites — including prompt injection resistance, guardrail robustness, and graceful degradation under ambiguous patient inputs.
  • Champion “shift-left” quality practices: embed eval criteria into prompt engineering workflows, define acceptance criteria for new agent behaviors, and make quality a first-class concern in the development cycle.
  • Contribute to the design of our QA pipeline orchestration (background processing, Slack notifications, risk assessment persistence) to improve throughput, reliability, and developer experience.
