We're looking for a Senior or Staff Product Engineer who loves building APIs that make hardware simple. You'll work on the core challenge of Seam: abstracting away the chaos of hundreds of device APIs into something developers actually enjoy using.
You'll integrate locks, thermostats, cameras, and sensors from dozens of manufacturers. You'll build the abstractions that hide Z-Wave complexity, manufacturer quirks, and protocol differences. You'll ship features from backend to frontend, talk directly to customers in Slack, and own products end-to-end.
This role is perfect if you get excited about making messy things clean, shipping fast, and building products developers love.
What you'll work on
Device Integrations – Build and improve integrations with IoT devices across manufacturers and protocols. Create reusable abstractions that scale.
Customer-Facing APIs - Design and ship APIs and SDKs that thousands of developers rely on daily. Make the complex simple.
0-1 Products - Identify opportunities and build new products from scratch. Recent example: our access scheduling system that handles millions of temporary codes.
Enterprise Connectors – Build direct integrations with enterprise customers' systems. Make Seam plug-and-play for large deployments.
Customer Success – Jump into customer Slack channels, fix bugs in real-time, gather feedback, and ship improvements based on what you learn.
Why Seam?
We're making the physical world programmable. If you've used a code to enter an Airbnb or had your office thermostat adjust automatically, you've probably used Seam.
You'll work with our Smart Home team that is based in Europe but will work directly with a PM that is in SF, you may have some early morning calls (8-9am) but otherwise work hours are PST. We value written communication, simple solutions, and shipping fast. Team includes alums from Nest, Apple, Stanford, YC. Backed by Tiger Global and founders from Stripe, Plaid, Airbnb.
Hybrid role in San Francisco (In office 3x a week), collaborating with our global team
