Senior QA Test Engineer GCC

Litmus is building the data foundation that powers industrial AI.

AI doesn’t work without real-world, contextualized data - Litmus makes that data usable. As AI adoption accelerates, most industrial environments still can’t access or use their operational data. We solve that gap.

We’re a growth-stage software company helping manufacturers access, structure, and use real-time data from machines, systems, and sensors at the edge. Our platform sits at the intersection of edge computing, AI, and industrial operations, enabling some of the world’s largest companies to run operations in real time,...

We are hiring Senior QA Automation Engineers to test our data cataloging and real-time data platform products. You will build reliable automation with Playwright, turn business and technical requirements into test cases, and work with developers and product owners to improve product quality.
We have openings in two areas: application and API automation for our data cataloging product, and end-to-end data validation for our real-time data platform. Your experience will help us identify the best fit. Both openings are hands-on automation roles.
· Develop and maintain automated UI tests with Playwright, using TypeScript or JavaScript, and build supporting test scripts and tools in Python where appropriate.
· Translate functional and non-functional requirements into clear test cases and automated coverage.
· Investigate test failures, work with developers to identify root causes, and improve test coverage and automation efficiency.
· Use Linux, Git and AI tools as part of your testing and automation work.
Depending on your product assignment, you will also:
· Automate API tests, build and troubleshoot Docker test environments, and set up and maintain CI pipelines for application testing.
· Test data flows from source systems to downstream destinations, checking completeness, correctness and consistency, and build scripts to generate test data and validate results at scale.

· QA experience with a strong focus on hands-on test automation.
· Practical experience building and maintaining automated tests with Playwright.
· Automation coding skills in TypeScript, JavaScript or Python, with strong TypeScript or JavaScript skills for the application automation opening.
· Confidence working in the Linux command line, using Git, and turning requirements into effective test cases.
· Experience using AI tools to support testing and test automation.
· Application and API automation: API testing experience; hands-on Docker skills, including building images, running containers and debugging; and experience with CI/CD practices and setting up pipelines in Jenkins, Git-based tooling or similar.
· Real-time data testing: 3–6 years of QA experience, including hands-on validation of data from source to destination; working knowledge of SQL and JSON; and the ability to automate data checks using Python or TypeScript/JavaScript. Docker and Kubernetes can be learned on the job.
· Experience with data processing or cataloging products, industrial or IoT data, or MQTT, Kafka and other pub/sub messaging systems.
· Kubernetes, performance or load testing, and CI pipeline setup experience for the real-time data opening.
