We’re hiring an experienced Sr.SDE for our Industries team within Special Projects. The team turns our core platform into purpose-built solutions for specific verticals, such as restaurants, healthcare, real estate, automotive, home services, and fitness.

As an Sr.SDE, you’ll build frontend-heavy full stack features that make our platform feel native to each industry. That means rich, interactive interfaces like floor plans, booking and scheduling views, industry dashboards, and guided setup flows. It also means configurable UI that adapts to each vertical’s data models and workflows.

• Design reusable, configurable UI components that render industry-specific objects, fields, and workflows without forking the core product
• Lead the technical design of frontend-heavy features, turn product and design concepts into high-quality interfaces, and shape the UX with designers and domain experts
• Evaluate frontend and full stack architectural trade-offs, balancing experimentation speed, user experience, performance reliability, scalability, and maintainability as solutions mature
• Own frontend performance, accessibility, and responsiveness across desktop, tablet, and mobile web, including views used live by staff on shared devices
• Build and extend the APIs behind your features using Node.js/NestJS, with Firestore, PostgreSQL, Elasticsearch, and Redis as data layers
• Handle real-time and async UI states, such as live updates,…
