The role…

We’re seeking a Senior Software Engineer (Frontend) to build the interfaces that give enterprise users visibility and control over AI-powered automated workflows.

You’ll turn complex capabilities into clear, intuitive product experiences, owning meaningful frontend features from initial requirements through release. Working closely with product, design, and backend engineers, you’ll help shape how customers interact with Maisa.

What you’ll do…

• Build responsive, accessible interfaces for complex enterprise workflows and data-intensive screens.

• Translate designs into polished experiences, including thoughtful interactions and loading, empty, and error states.

• Develop composable, maintainable components and contribute to shared UI patterns and design systems.

• Make sound decisions around state ownership, rendering, and component design.

• Integrate REST APIs using TanStack Query, managing caching, mutations, and data consistency.

• Write meaningful automated tests and resolve interface performance bottlenecks.

• Partner with product, design, and backend engineers to clarify requirements, evaluate trade-offs, and deliver features from concept through release.

• Contribute to code reviews, documentation, and engineering standards, supporting backend work when needed.

What you’ll bring…

• A proactive approach, strong ownership, and comfort working in a fast-moving environment.
