About this role
Senior/Staff Product Engineer
About the role
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.
Qualifications
7+ years software engineering with strong backend focus
Expert TypeScript/JavaScript
Deep REST API design experience
PostgreSQL proficiency
Track record of integrating third-party APIs at scale
Experience shipping customer-facing products
Comfortable with React/frontend when needed
Preferred Qualifications
IoT or hardware integration experience
Familiar with device protocols (Z-Wave, Zigbee, MQTT)
Built developer tools or SDKs
Experience with real-time systems
