Job description

Who is Litmus

LitmusLitmus 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.

What You'll Do

• Own the overall technical architecture of the platform - set the long-term vision and make the hard calls that balance speed, scale, and maintainability.
• Drive architectural decisions across multiple teams and systems, ensuring consistency, reliability, and developer velocity.
• Identify systemic engineering problems early and lead solutions that create org-wide leverage.
• Partner with engineering leads to design and review critical systems before they're bu
