Job description

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

Litmus is looking for a talented and passionate React.js Developer to help build and enhance the user experience across our product portfolio. You will play a key role in designing and developing modern, scalable, and high-performance web applications that enable users to explore and interact with complex industrial and operational data.

Working closely with Product Managers, UX Designers, and Backend Engineers, you will contribute to the development of intuitive, responsive, and accessible interfaces while driving frontend best practices, performance optimization, and engineering excellence.

What You’ll Do

• Design, develop, and maintain high-quality React.js applications and reusable UI components.
• Enhance and evolve key product modules, including asset search, metadata management, and interconnected data exploration experiences.
• Collaborate with UX/UI designers to deliver pixel-perfect, responsive, and accessible user interfaces.
• Integrate frontend applications with GraphQL APIs and RESTful services.
• Optimize application performance through lazy loading, code splitting, memoization, and bundle optimization techniques.
• Build and maintain scalable state management solutions using Redux, Zustand, or React Context.
• Write robust unit and integration tests using Jest and React Testing Library.
• Participate in code reviews, technical design discussions, sprint planning, and agile ceremonies.
• Contribute to internal component libraries and help maintain design system standards.
• Troubleshoot and resolve UI/UX issues while continuously improving the user experience.
• Work with containerized environments and collaborate with DevOps teams to support deployments and troubleshooting.

What You’ll Bring

You are a frontend engineer who enjoys building complex user interfaces, solving challenging technical problems, and delivering exceptional user experiences. You thrive in collaborative environments, have a strong eye for detail, and are passionate about writing clean, maintainable, and performant code.

• Strong understanding of responsive design, CSS‑in‑JS solutions (Styled Components, Emotion), and frontend architecture.
• Experience working with Ant Design component library.
• Proven ability to build complex, data‑intensive user interfaces and navigate interconnected datasets.
• Familiarity with graph and node‑based visualization libraries such as React Flow, D3.js, or Cytoscape.
• Experience with modern frontend build tools including Webpack, Vite, and Babel.
• Strong understanding of browser rendering, frontend performance optimization, and web application scalability.
• Experience writing automated tests using Jest and React Testing Library.
• Proficiency with Git and collaborative development workflows, including pull requests and branching strategies.
• Understanding of OAuth/OIDC authentication mechanisms and Role-Based Access Control (RBAC).
• Comfortable working in Linux environments with command-line tools, log analysis, and basic shell scripting.
• Practical experience with Docker and Kubernetes, including environment setup, container troubleshooting, and deployment diagnostics.

Nice to Have

• Experience working with Industrial IoT (IIoT), IoT, manufacturing, or data platform products.
• Exposure to backend technologies such as Python or GraphQL server-side development.
• Experience contributing to open-source projects.
• Familiarity with AI-assisted development tools such as GitHub Copilot, Claude Code, or similar platforms.
• Understanding of CI/CD pipelines and DevOps practices using GitHub or GitLab.
• Experience troubleshooting deployment pipelines and production environments.
