Seam builds the infrastructure that connects software to the physical world. With Seam, companies create products that automate spaces, streamline operations, and elevate everyday experiences—like unlocking doors, managing climate, and monitoring properties from anywhere.
Our customers include property management platforms, commercial integrators, and startups building for offices, gyms, and co-working spaces. If you’ve ever checked into an Airbnb with a code, you’ve probably used Seam without realizing it.
Seam is backed by Tiger Global, Root Ventures, YC, founders from WhatsApp, Flexport, and execs at Stripe, Plaid, Fastly, and Airbnb, and many more.
As the lead product designer at Seam, you’ll define how our platform looks, feels, and works. Our product extends beyond the API—we provide SDKs, embeddable components, hosted UIs, dashboards, and consumer apps. These are the touchpoints where customers and their users experience Seam, and design is central to making them clear, intuitive, and trustworthy.
You’ll set the foundation for our brand identity, design system, and product design practices as we expand into new areas. The challenge is to create products powerful enough for organizations managing millions of devices, yet approachable for anyone to use. Success in this role means shaping experiences that feel effortless without sacrificing depth, and establishing a design culture that raises the bar for usability and polish across the company.
You’ll lead design across Seam’s core product surfaces, from the dashboard and embeddable components to hosted UIs and consumer apps. You’ll translate technical workflows into approachable, polished experiences that customers trust and developers enjoy. You’ll collaborate closely with product and engineering to make sure design decisions are grounded in customer needs and ship quickly without losing clarity or quality. Along the way, you’ll establish systems, patterns, and standards that keep design consistent and scalable as Seam grows.

Seam provides a universal API and fully managed, no-code toolset that makes it incredibly easy for software platforms to integrate, automate, and orchestrate IoT devices across industries. Instead of negotiating with manufacturers, handling inconsistent APIs, or building custom logic for every brand, teams rely on Seam to unify smart locks, thermostats, sensors, and full access control systems under one simple layer—no integration work required.
Seam was built to solve one of the hardest problems in software: device integrations. Manufacturer APIs are inconsistent, require lengthy business development, and demand ongoing maintenance. Companies often repeat this work across multiple brands—costing months of engineering time before they can ship a single feature. Seam removes that complexity and now goes far beyond integration.
Alongside our universal API, Seam offers a suite of ready-to-use products that accelerate time to market:
A unified API that normalizes and extends manufacturer APIs
SDKs that speed up development
Embedded UI components for instant device-management interfaces
Authentication flows to connect third-party device accounts
A fully managed Customer Portal with prebuilt UI for end users to connect, map, and monitor devices—no-code
Automation Workflows that sync access with reservations, issue codes, manage climate, and more
Connectors that integrate directly with PMS and industry systems so teams can deploy automation with zero integration work
With Seam, teams can orchestrate powerful automations—issuing mobile keys, generating time-limited codes, adjusting climate, syncing reservations, or unifying building operations—without building integrations or custom workflows.
Today, Seam powers software across short-term rentals, hospitality, multifamily, commercial real estate, fitness, education, and more.
We make IoT work for software—so teams can focus on delivering exceptional experiences, not managing integrations.
