Who we are

About Seam

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.

About the role

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.

What you’ll do

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.

Responsibilities

• Own design end-to-end, from early concepts to polished interfaces in production.
• Build and maintain systems, patterns, and standards that keep design fast and consistent.
• Partner with product managers, engineers, and leadership to align design decisions with company goals.
• Communicate concisely and clearly with teammates, balancing autonomy with collaboration.
• Model resourcefulness by moving fast, finding creative solutions, and navigating constraints.
