Sr. Software Engineer, Automation Experience (Remote Eligible from Bulgaria)

You Will:

Own the Workflow UI Experience

• Architect, build, and iterate on the Workflow Builder front-end, delivering a performant, accessible, and delightful drag-and-drop editing experience.
• Drive component design, layout systems, and interaction patterns that scale across Smartsheet's enterprise customer base.
• Champion visual quality, pixel-precision, and a high bar for UX polish throughout the development lifecycle.

Develop with React & UI Libraries

• Build production-grade features using React (v18+), leveraging hooks, context, concurrent rendering, and Suspense for advanced UI behaviors.
• Integrate and extend component libraries (e.g., MUI, Radix UI, Shadcn/ui, or internal design system components) to create a consistent, reusable UI language across the product.
• Evaluate and champion the adoption of new React capabilities and ecosystem tooling that improve developer productivity and user experience.

Build Scalable and Secure Services

• Develop scalable back-end services and APIs with a security-first mindset, ensuring high availability and performance in our multi-cloud environment (primarily AWS).
• Create and maintain API integrations between internal and external systems. Implement and test API solutions to ensure they meet functionality, performance, and security standards. Monitor API performance and address any integration challenges or issues.
• Participate in architectural discussions and code reviews, advocating for front-end best practices: code splitting, memoization strategies, accessibility (WCAG AA), and performance budgets.
• Define and uphold front-end coding standards, patterns, and automated testing strategies (unit, integration, visual regression) across the pillar.

Deliver High Quality at Scale

• Write comprehensive unit and integration tests (Jest, Cypress, Playwright) with a strong culture of test-driven development and visual regression coverage.
• Monitor front-end performance metrics (Core Web Vitals, bundle size, rendering throughput), identify bottlenecks, and drive measurable improvements.
• Partner with UX designers to translate wireframes and prototypes into refined, fully accessible UI components.

Mentor & Lead

• Serve as a UI subject matter expert for the team, mentoring junior and mid-level engineers on React best practices.
