Frontend Engineer (React.js)

About the role

Fnkt Labs is a Singapore-based foodtech startup serving F&B operators, cloud kitchens and hawker-style vendors with ordering, inventory and analytics tools. Our product suite includes merchant dashboards, consumer order flows and integrations with POS systems used across cafés, zi char stalls and heartland malls.

The Frontend Engineer (React.js) will join a small cross-functional product squad focused on improving checkout conversion, merchant dashboard usability and in-venue kiosk performance. You will be responsible for building reusable UI components, improving load times for high-traffic lunch and dinner peaks (CBD lunch crowd patterns), and working with design to deliver accessible, responsive experiences.

This role is attractive if you want to work at the intersection of tech and F&B: you'll see products in real operating environments (kopitiam-style POS, hawker kiosks and boutique restaurants) and have the opportunity to influence product direction, own features from design through production and grow into a technical lead role.

About Fnkt Labs

Fnkt Labs builds pragmatic SaaS and consumer-facing web apps for the food and beverage industry. We partner with restaurants, cloud kitchens and hawker collectives to digitise ordering, streamline back-of-house operations and surface actionable insights for small and mid-sized F&B operators.
