About the company

Supaboard is an AI-powered business intelligence platform that helps teams turn scattered data into clear, actionable insights without needing deep technical skills. The product connects to multiple data sources, lets users ask questions in plain English, and delivers instant dashboards and reports so businesses can make faster, smarter decisions.

Culture and ownership

Supaboard runs as a high-ownership, low-ego environment where every engineer is treated as a product owner, not just a ticket closer. Frontend developers are expected to own problems end-to-end—understanding the user, shaping the solution, implementing it, measuring impact, and iterating quickly based on real-world usage.

Role overview

As a Frontend Developer at Supaboard, you will build modern, performant interfaces that make complex analytics feel simple and intuitive for non-technical users. You will work closely with founders, designers, and backend engineers, owning key parts of the product experience from concept to production. This role is ideal for someone who wants meaningful product ownership, fast feedback loops, and the opportunity to shape the core product early.

Responsibilities

• Build and maintain responsive, high-quality frontend features using React and TypeScript.  
• Take end-to-end ownership of user-facing workflows: understand user needs, propose UX flows, implement, and iterate based on feedback and data.  
• Collaborate with design and backend teams to ship smooth, coherent product experiences rather than isolated components.  
• Continuously improve performance, reliability, and usability of the app with a focus on perceived speed and UX.  
• Participate in code reviews, technical discussions, and roadmap conversations, bringing product-thinking to engineering decisions.  

Required skills

• Strong proficiency in React, React Query, TypeScript, HTML5, Tailwind and CSS3.  
• Familiarity with Monorepos.
• Experience working with Node.js-based backends and RESTful APIs.  
• Familiarity with modern frontend tooling (e.g., Vite/Bun, package managers, linting and formatting tools).  
• Solid understanding of component-driven development, state management, and reusable UI patterns.  
• Ability to take a problem statement, break it down, and drive it to completion with minimal supervision.  

Nice to have

• Exposure to testing tools such as Jest, Testing Library, or Cypress.  
• Experience in data-heavy products, dashboards, or BI/analytics tools.  
• Understanding of accessibility best practices and performance profiling.  

Qualifications

• 1+ year of professional experience in frontend development (internships and full-time roles both count).  
• A portfolio, GitHub, or project links that demonstrate your ability to ship real-world frontend work.  

Why join Supaboard

• Direct impact and ownership on core product surfaces used by real customers.  
• Work closely with the founding team on product and technical decisions from the ground up.  
• Opportunity to grow into a lead/ownership role as the company and team scale.
