About the role
OneByZero builds Neo, an enterprise agentic platform for creating and deploying AI agents across chat, voice, and messaging channels for major banks, telcos across APAC. We're hiring a QA Engineer to own automated testing across our product suite and build reliable test coverage for the NEO platform.
This is an automation-first, hands-on testing role. You'll write code every day, own quality end-to-end for major product surfaces, and have real influence over how we ship.
What you'll do
-
Own QA end-to-end for key product areas — define the test strategy, build the automation, and be accountable for release quality.
-
Design and maintain deterministic, reliable automated tests across the pyramid: API/integration, end-to-end UI, regression, and load.
-
Build and scale our API integration test suites (Jest/TypeScript over live HTTP) against live microservices — covering auth, contracts, data lifecycle, and error paths.
-
Convert our existing manual test suite into automated regression coverage and keep CI green.
-
Run load and performance testing (k6) — modeling scenarios, defining SLOs, and reporting on results.
-
Integrate tests into CI/CD (GitHub Actions), manage flaky tests, and improve reporting and gating.
-
Partner with engineering to catch issues early and raise the quality bar across the team.
Requirements
What we're looking for
-
5+ years in automated QA, ideally in an SDET or QA-ownership capacity.
-
Strong hands-on coding in TypeScript and/or Python — our entire test estate is code, version-controlled, and CI-gated.
-
Proven depth in API/integration testing of microservices using a code-based framework — Jest/Supertest, pytest, REST Assured, or similar (REST; bonus for GraphQL and contract testing).
-
Solid experience with E2E UI automation (Playwright / Selenium) and a track record of building stable, deterministic suites.
-
Experience owning a regression suite — selection, maintenance, and triage.
-
Load/performance testing experience (k6).
-
Comfortable with CI/CD pipelines, Docker, and Git-based workflows.
-
Demonstrated ownership and agency — you've led QA for real software (API, UI, integrations, regression, load) rather than just executing test plans.
-
Background in enterprise software or a cloud/SaaS startup selling to enterprises.
Nice to have
-
Experience testing conversational AI, voice/telephony, RAG/knowledge-base, or channel-integration products.
-
Exposure to agentic / LLM-system testing (model-graded evals, guardrails, eval datasets) — a bonus, as we standardize on deterministic testing.
-
Working knowledge of Kubernetes/Helm and AWS.
-
Observability-driven debugging (OpenTelemetry, Grafana, Prometheus).
-
Security or compliance testing exposure, ideally in a regulated/enterprise (banking, telco, insurance) context.
-
Experience with owning test suite for Desktop / Mobile application
Benefits
Why OneByZero
-
Build at the frontier of enterprise agentic AI serving large customers across APAC markets.
-
High ownership and direct impact on how a fast-growing platform ships.
-
Work with a modern stack: TypeScript (Next.js, tRPC), Python microservices, AWS, and a mature automated-testing culture.
