Who is Litmus

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, reduce downtime, and optimize production.

Backed by leading investors and trusted by global manufacturers and partners like Google, Microsoft, Dell, Oracle, and Mitsubishi, Litmus is powering the shift toward software-defined manufacturing.

Why join Litmus

Build the infrastructure that makes industrial AI possible

AI is moving beyond the cloud and into the physical world. At Litmus, you’ll build the infrastructure that enables real-time data to power AI and machine learning systems in production environments.

Work on problems where software meets the real world

Most AI systems fail without access to real-world data. You’ll build the layer that makes them viable in production. We solve challenges at the intersection of distributed systems, real-time data, and industrial constraints — where reliability, scale, and performance are non-negotiable.

Have real impact, fast

You’ll work on systems used by real customers in production, with direct impact on product and company trajectory. As a scaling company, we move quickly. You’ll have ownership, visibility, and the ability to shape both product and company as we scale.

Join a high-performance team

We’re building a team that holds a high bar and pushes each other to improve. You’ll work alongside experienced operators, engineers, and leaders who have done this before and are building again at scale. We hire people who take ownership, move quickly, and care about outcomes. No passengers.

Our culture

At Litmus, the team is collaborative, curious, and low ego. People are scrappy, take ownership, and look for ways to make an impact. We value empathy just as much as execution, whether that’s in how we build, how we communicate, or how we support each other.

We’re a growing company, so things move quickly and not everything is perfectly defined. If you enjoy figuring things out, working closely with others, and making steady progress, you’ll do well here.

About the Role

We are hiring a Senior QA Test Engineer for Litmus Edge Manager (LEM), the product our customers use to manage large fleets of edge devices. You will own test automation for LEM in our Pune team. You will build and grow the Playwright test suite in TypeScript, keep it running in CI, and cover new features as they ship.

The work splits about 90% automation and 10% manual testing, so this is an automation role first.

You will work day to day with the LEM QA lead in Pune and with the LEM development team. LEM QA ownership is moving to Pune now, so the way this product is tested is still being shaped and your work will set that standard.

What You'll Do

• Build and maintain end to end UI and API tests for LEM with Playwright and TypeScript

• Grow automation coverage release by release, starting with the flows that carry the most risk

• Keep the suite running in CI, look into failures, and fix flaky tests instead of muting them

• Write and maintain LEM test cases in Xray and link them to Jira, so coverage per release is visible

• Use our AI assisted test generation tooling to draft test cases and Playwright specs, then review and correct the output

• Join tickets early and check the acceptance criteria are clear enough to automate against

• Run the automated regression suite for LEM releases and report the results, including LEM and Litmus Edge integration checks

What You'll Bring

Must Have

• Minimum 3 years of automation testing experience, inside 5+ years in software testing

• Strong TypeScript or JavaScript, and hands on experience with Playwright (Cypress or Selenium is fine if you are ready to move to Playwright)

• REST API testing, and comfortable working on Linux

• Hands on with virtual machines: building, snapshotting and restoring test environments on your own

• Experience running automated tests in a CI/CD pipeline, and with a test management tool such as Xray

Nice to Have

• Experience with AI assisted test generation or other AI tooling for QA

• Docker

• Kubernetes

• Background in industrial IoT, edge or device management products

• Performance testing experience, JMeter or similar
