Role Description
ENFOS Inc. is hiring a Senior UI Engineer to help architect and lead the modernization of the front end of our Environmental Obligation Subledger Accounting Platform. This is a mission-critical system of record used by global industrial enterprises to govern material Environmental Obligation Programs under U.S. GAAP and IFRS standards. You will define how finance, accounting, and operations stakeholders engage with dense financial, scientific, and operational data within a multi-regulatory reporting framework.

- Translate complex financial and regulatory requirements into intuitive, user-centered workflows
- Define scalable front-end architecture patterns for performance, state management, and API integration
- Establish and govern a formal design system and reusable component library
- Optimize large data grids, reporting views, and multi-entity workflows for clarity and speed
- Partner with Product and Engineering to influence roadmap and system-level architecture decisions
- Build scalable pages and modular React components aligned with long-term maintainability
- Continuously elevate usability, interaction quality, and visual consistency across the platform
Additional Responsibilities
- Establish and maintain design standards, documentation, and system-level consistency across the application
- Collaborate with Sales and Marketing on product positioning, launches, and customer-facing materials
- Mentor front-end and full-stack engineers on UI craftsmanship, usability best practices, and design quality
