Frontend Developer

We are looking for a skilled Frontend Developer to join our core product team at Infyllo. You will be responsible for building and maintaining the user-facing layers of a data-intensive platform, including real-time dashboards, AI-powered conversational interfaces, data visualisation components, and proactive alert systems.

You will work closely with the founding team to translate product requirements into clean, performant, and intuitive interfaces that make complex business data immediately understandable to non-technical users. You will own the frontend architecture, set standards for code quality, and play a key role in shaping the user experience of a fast-growing product.

This role requires strong engineering fundamentals, a deep understanding of modern React patterns, and a proven ability to build production-grade interfaces that handle real-time data at scale. You are someone who takes pride in both the technical quality and the visual precision of everything you ship.

ABOUT INFYLLO :

Infyllo is an AI powered operational intelligence platform for manufacturing and SMB businesses. Business owners today are running their operations across multiple disconnected tools: accounting software, ERPs, spreadsheets, payroll systems, and sales platforms, with no platform to get the full picture.

We fix that. Infyllo connects all of a business’s data automatically and delivers real-time intelligence so owners can ask any question about their business and get an instant answer, see everything in one live dashboard, and get alerted to risks and opportunities before they become problems that cost money.

We are an early-stage startup with a product that is moving fast. We are a small, focused team that ships quickly and takes quality seriously. Every line of code matters. Every design decision matters. You will not be a cog in a large machine. You will be a core part of what we build next.
