Responsibilities

Design, develop, and execute detailed test plans, test cases, and test scenarios for a life-critical voice AI platform: automated welfare and emergency-adjacent calling where an undetected defect can mean a vulnerable person is not reached. Testing here is a safety function, not a formality.

Perform manual testing (functional, regression, exploratory, usability) and contribute to automated testing across web dashboards, REST and gRPC APIs, and cloud-hosted services.

Perform regression, smoke, sanity, and end-to-end testing across releases on both staging and production.

Validate AI-driven behaviour end to end: speech-to-text transcription accuracy against recorded audio fixtures, LLM agent responses and prompt regression, tool and action invocation correctness, turn-taking and barge-in behaviour, answering-machine detection, text-to-speech output, and call-outcome extraction. This means testing non-deterministic systems: designing tolerance-based assertions and fixture-driven suites rather than exact-match checks,



and running against recorded audio and transcripts instead of live vendor calls.

Conduct API testing across REST and gRPC surfaces using Postman, Bruno, or equivalent, and build contract tests derived from API and schema definitions so that a contract change is caught by a failing test rather than by a customer.

Own security testing as part of the same role, not as a separate track: write and run test cases against the OWASP API Top 10 (broken object-level authorization, broken authentication, excessive data exposure, mass assignment, missing rate limiting), and triage the automated security gates in CI (dependency vulnerability scanning, container image scanning, secret scanning, license checks).

Test multi-tenant isolation and access control as a first-class scenario: verify every tenant-scoped path enforces organisation isolation and role and permission gates, and that no endpoint, filter, or export can return another tenant's da
