Senior QA Testing Engineer

Who is Litmus
Litmus is building the data foundation that powers industrial AI.
AI doesnt work without real-world, contextualized data - Litmus makes that data usable. As AI adoption accelerates, most industrial environments still cant access or use their operational data. We solve that gap.
Were 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 worlds 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, youll 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. Youll 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
Youll work on systems used by real customers in production, with direct impact on product and company trajectory. As a scaling company, we move quickly. Youll have ownership, visibility, and the ability to shape both product and company as we scale.
Join a high-performance team
Were building a team that holds a high bar and pushes each other to improve. Youll 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 thats in how we build, how we communicate, or how we support each other.
Were 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, youll do well here.
