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.

About Guava

Guava is the voice platform built for regulated industries — the calls that have to be right. Trained on 10B+ live agent minutes and in regulated production since 2013, Guava gives enterprises a single, compliant system for every second of a call. We serve healthcare systems, banks, insurance carriers, BPOs, and tech-native companies that need voice infrastructure they can stake their business on.

Reliability, latency, and audio quality aren't nice-to-haves here — they're the product. Every conversational flow, every API integration, and every real-time voice pipeline has to hold up under real usage before it reaches a customer, and that's where QA comes in.

The Role

Guava is looking for a QA Engineer to own quality across our voice agent platform. You will design and execute test strategies for conversational flows, real-time audio pipelines, and the APIs developers build on — catching issues before they reach production and helping the team ship fast without breaking things.

This is a hands-on role that blends manual exploratory testing — talking to and stress-testing voice agents — with building durable automated test coverage.

What You'll Do

• 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.

What We're Looking For

• 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.

Nice to Haves

• Experience testing voice, audio, or telephony systems (IVR, contact center, or conversational AI products).
• Experience owning backwards compatibility for a public SDK — designing and maintaining a version compatibility matrix, building contract tests that catch breaking changes in CI, and defining deprecation policy.
• Familiarity with load/performance testing tools.

Why Guava

• Own quality for a voice AI platform running in real, regulated production — not a research demo.
• Direct access to engineering leadership; no layers.
• Join a technical team building the reliability and audio quality the product depends on.
• Full health, dental, vision; employer 401(k) match; PFL/CFRA-compliant parental leave; flexible PTO.

Guava is an equal opportunity employer. We welcome applicants of all backgrounds and are committed to building a diverse and inclusive team.
