Description
About Engineering At Fonoa
Engineering is central to how we build the business. We focus on solving real customer problems, not just shipping features. We work in small, high-trust teams, with full ownership across the lifecycle, from design to production and beyond.
We value:
As Fonoa continues to evolve beyond APIs into a broader platform experience, we are looking for a Frontend Engineer to help redefine how our products are designed, built, and experienced across the company.
This role goes far beyond implementing interfaces. You will play a foundational role in shaping the future of the Fonoa platform — from customer-facing products and internal tooling to the overall design system, interaction patterns, and frontend architecture that ties everything together.
We are looking for someone who cares deeply about product experience, systems thinking, and frontend craftsmanship. Someone who can work closely with product, engineering, and design to build products that feel fast, intuitive, and thoughtfully designed, while also helping define how frontend engineering operates and scales at Fonoa.
As our platform evolves toward more intelligent, agent-driven workflows, the frontend becomes a critical part of the experience. We want to move beyond traditional dashboards and workflows toward interfaces that feel more dynamic, contextual, and assistant-like, helping customers navigate complex compliance and tax operations in a much more seamless way.
This is a highly collaborative, hands-on role for someone who thrives in ambiguity, enjoys shaping products from first principles, and wants to have a meaningful impact on both the user experience and the engineering culture around frontend development.
We are not looking for someone to simply “build screens.” We are looking for someone who can help define:
Engineering is central to how we build the business. We focus on solving real customer problems, not just shipping features. We work in small, high-trust teams, with full ownership across the lifecycle, from design to production and beyond.
We value:
- Ownership – engineers own what they build end-to-end
- Simplicity – we break down complex problems into clear solutions
- Thinking Big - we innovate with modern technologies (LLMs, AI Agents, etc.) to solve meaningful problems
- Quality – scalable, maintainable systems are non-negotiable
- Speed & iteration – we ship fast, learn, and improve continuously
- Collaboration – we win as a team, not as individuals
