• Development of the Order Management System - Allvue, Black Mountain, Everest , BMS • Implement interfaces to third party systems using XSLT, XML, and SQL technologies • Create rules and data transfer mappings using XPath and XSLT • Work with Business users on defining spec QA and Testing

• Architect the Frontend Platform: You own the "how" of our frontend. • Design System Governance: Lead the evolution of our component library via Storybook. • Engineer the "Painless Editor": Lead the development of our content creation suite. • Uphold UX Fidelity & Performance: You are the guardian of the "feel" of the product. • Lead Through Curiosity: You act as a strategic partner to Design and Product, translating high-level vision into concrete component architectures. • AI-Native Engineering Leadership: Set the bar for how we use Claude and Cursor.

• You’ll find what this role is all about—the impact you’ll drive, the challenges you’ll tackle, and what it takes to thrive at Addi. If you’re ready to be part of something big, keep reading. • Strong desire to learn and stay updated with new technologies, tools, and best practices. • Work against ambitious timelines and deliver consistently high-quality results.

• Own the mapping experience as a product-quality system: build and evolve a high-performance geospatial UI where interaction design, performance, and reliability are treated as first-class concerns. • Build “pro-grade” geospatial editing workflows: create tools for drawing and editing points/lines/polygons, including selection states, snapping, validation rules, undo/redo, and exportable artifacts. • Deliver a styling/symbology experience users trust: implement a layer/style editor that supports portable styles, sensible defaults, and powerful “color/size by attribute” workflows — without overwhelming users. • Make large datasets feel smooth: profile performance, manage memory responsibly, and use the right techniques (virtualization, background computation, incremental updates) so everything stays responsive. • Design robust state and interaction architecture: build a maintainable foundation for complex UI state, event handling, and tool modes — the kind that doesn’t collapse when features scale. • Collaborate in a “product trio” style: work closely with product and design, and partner with domain experts to translate real workflows into interfaces that users love and trust. • Ensure technical excellence: write clean, testable TypeScript, build reusable UI components, and help establish patterns that keep velocity high without sacrificing stability. • Communicate clearly and proactively in remote work: tailor communication for different audiences, document decisions, and keep momentum without needing constant meetings. • Bring your own lessons learned: apply what you’ve learned from past product wins and failures to help OET level up.
