About The Position

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.

• 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.

Nice To Haves

• IoT or hardware integration experience.
• Familiar with device protocols (Z-Wave, Zigbee, MQTT).
• Built developer tools or SDKs.
• Experience with real-time systems.

Responsibilities

• Build and improve integrations with IoT devices across manufacturers and protocols.
• Create reusable abstractions that scale.
• Design and ship APIs and SDKs that thousands of developers rely on daily.
• Identify opportunities and build new products from scratch.
• Build direct integrations with enterprise customers' systems.
• Jump into customer Slack channels, fix bugs in real-time, gather feedback, and ship improvements based on what you learn.

Benefits

• 100% employer-paid health insurance + 75% dependent coverage.
• 401K, family-building support, mental health services.
• Generous PTO.
• Daily lunch in SF office.
• $160k - $230k base + meaningful equity (Senior/Staff level dependent).
