Senior QA Automation Engineer

ABOUT LINGO

Lingo is building a cutting‑edge digital health platform that fuses continuous biosensor data, high‑performance backend engineering, and advanced analytics to help people live healthier, longer, fuller lives. Our systems process massive volumes of real‑time data, and the backend is the heartbeat of the platform.

THE OPPORTUNITY

Build, maintain, and run automated tests for our iOS/Android apps and core backend APIs in a multi-region, cloud-native platform that uses Kubernetes and event-driven messaging (Kafka/RabbitMQ). You’ll focus on high-value automation (critical paths, smoke/regression, targeted end-to-end) and CI integration to provide fast, reliable feedback. You’ll also produce audit-ready evidence to support HIPAA/GDPR requirements in a regulated environment.

WHAT YOU’LL DO

Mobile automation focus: Own deep, native automation for one primary platform (iOS with XCUITest/XCTest or Android with Espresso). Use tools such as Appium for smoke coverage on the secondary platform.

Setup integration test that validates APIs that serves the app. Essentially setting up and maintaining automated tests for critical REST endpoints (and gRPC where applicable), covering happy paths, key edge cases, and regressions.

End-to-end flows: Implement 2–3 high-value E2E journeys that stitch mobile backend data, prioritizing reliability of the most business-critical scenarios.

Performance smoke: Add lightweight checks (e.g., app startup, memory, network/offline handling; API latency thresholds) rather than full load/soak suites.

CI/CD integration: Gate PRs and releases with fast, parallelized runs.

Observability-assisted debugging: Use logs, metrics, and traces to triage failures quickly and validate fixes with developers.

Platform alignment: Collaborate with Backend/Platform to validate multi-region services on Kubernetes/service mesh and event-driven paths using Kafka/RabbitMQ where applicable

Compliance evidence: Produce traceable, auditable test artifacts to support HIPAA/GDPR and change control requirements

REQUIRED QUALIFICATIONS

+5 years in QA automation or SDET roles with hands-on coding.

Strong experience with mobile test frameworks (XCUITest or Espresso, Appium for cross-platform smoke).

API test automation experience for REST (REST-assured, Postman, or similar); solid understanding of backend service testing.

CI/CD integration (e.g. GitHub Actions/Azure DevOps), parallel execution, and results/reporting.

Skilled at debugging with logs/metrics/traces, able to isolate issues across app, API, and environment layers.

Experience generating audit-ready test evidence in compliance-focused environments (HIPAA/GDPR)

PREFERRED QUALIFICATIONS

Familiarity with distributed systems and messaging and services deployed on Kubernetes/service meshes

Performance tools for smoke checks (k6, JMeter) and mobile network/offline testing.

Experience in digital health or other regulated, data-intensive products
