We are building a modern, high-complexity Inventory Management platform from the ground up and are looking for a Senior React Engineer to help shape and implement the front-end architecture. You will work on real-world enterprise logic, including inventory costing, purchasing flows, document lifecycles, logistics movements, accounting validations, multi-tenant constraints, and performance optimization under large datasets. If you enjoy designing systems that must be correct, consistent, and scalable, this role is for you. What Makes This Role Different - You will work on deep business logic, not superficial UI layers. - The front-end is treated as a first-class system — not a thin wrapper over APIs. - We care about architectural clarity, state isolation, validation correctness, and long-term maintainability. - Specifications are detailed. Edge cases matter. Data integrity matters. - You’ll be trusted to think, not just execute tickets. Your Responsibilities - Design and implement a scalable React architecture for complex ERP workflows - Build high-density data grids and validation-heavy forms - Implement multi-step document lifecycles with strict business rules - Structure reusable hooks and state modules with long-term maintainability in mind - Collaborate closely with .NET backend engineers on contracts and behavioral alignment - Refactor and improve code proactively where architectural improvements are needed - This is an individual contributor role. No management overhead — pure engineering. Required Background - 5+ years of professional React experience - Strong TypeScript in large-scale applications - Experience building complex enterprise systems (ERP, CRM, fintech, logistics, accounting, or similar domains) - Deep understanding of modern React patterns (hooks, composition, controlled state boundaries) - Experience handling complex validation logic and workflow-driven UI states - Strong attention to detail and architectural discipline Preferred - Experience with modern C# / latest .NET - Familiarity with domain-driven concepts - Experience working in structured, specification-heavy environments - Performance optimization in data-intensive applications Engineering Environment - Latest React + TypeScript - Modern .NET backend - AI-assisted development via Cursor (required) - Transparent time tracking via Hubstaff activity recording (mandatory) Who We’re Looking For - Someone who has built real systems with consequences. - Someone who understands how modern Inventory Management systems integrate into various ecosystems such as accounting and ecommerce. - Someone who prefers ownership over supervision.
