Job summary

Guava is seeking a QA Engineer to own quality across its voice agent platform, designing and executing test strategies for conversational flows, real-time audio pipelines, and APIs. This hands-on role blends manual exploratory testing with durable automated test coverage.

You will design, write, and maintain test plans, build automated suites for APIs and integrations, and collaborate with engineering to define acceptance criteria and ensure smooth releases.

Qualifications

• 3+ years of experience in QA, SDET, or a related software testing role.
• Experience testing APIs and backend services, and writing test automation (e.g., Python, pytest, Postman/Newman, or similar).
• Strong exploratory testing instincts — comfortable digging in without a fully scripted test case.
• Clear, precise bug reports and comfort working directly with engineers to resolve them.
• Solid understanding of CI/CD and how automated testing fits into a release pipeline.
• Based in or willing to work from Guava's Downtown Los Angeles (Arts District) office.

Responsibilities

• Design, write, and maintain test plans for voice agent conversational flows, including edge cases, interruptions, accents, and noisy audio conditions.
• Build and maintain automated test suites for backend APIs and integrations (regression, functional, and end-to-end).
• Benchmark AI systems for quality and performance.
• Test real-time voice pipelines end-to-end — ASR, TTS, latency, and call quality — across telephony integrations (SIP/PSTN) and supported platforms.
• Partner with engineering during feature development to define acceptance criteria and catch issues pre-release.
• Own release regression testing and sign-off before deploys.
• Track, triage, and clearly document bugs; work with engineers through resolution and verification.
• Monitor production quality signals (call success rate, latency, failure modes) and flag regressions.
• Help build out QA process and tooling as the team and platform scale.
