Job description

Who We Are

the company is transforming how organizations protect their people and places with an integrated, privacy-sensitive AI-powered platform that includes solutions for video security, access control, air quality sensors, alarms, intercoms, and visitor management.

We’ve got serious momentum in the market: more than 30,000 customers (including 100+ of the Fortune 500), a $5.8B valuation, more than $1 billion in annualized bookings, and backing from CapitalG, Sequoia Capital, General Catalyst, Felicis Ventures, Next47 and more. Physical AI is one of the most consequential technology shifts of our time, and the company is at the center of it.

You can look at all kinds of communities to see our platform’s impact in the world. It's the retailer that uses our agentic AI to deter theft before it happens. The warehouse that uses AI-powered alerts to make sure its team is protected on the floor with proper PPE. The school that’s alerted to a threat in real-time and triggers a lockdown in seconds, not minutes. We’re rapidly scaling this impact: today, more than 2 million the company devices are deployed across 170+ countries.

About the Alarms Team:

The Alarms team builds systems that detect, verify, and respond to real-world security threats using sensors, cameras, and AI. You’ll work on products that are critical during high-stakes moments and directly impact customer safety.

About the Role

the company’s Alarms team builds the intelligent systems that detect, verify, and respond to real-world security threats—whether it's a break-in or suspicious activity caught on video. We combine intrusion sensors, cameras, and AI to create a fast, reliable, and modern security experience.

As a Backend Engineer, you’ll play a key role in designing and scaling our AI-driven detection and response workflows. These systems power automated threat identification, customer notifications, video verification, and emergency dispatch—all in real time. You’ll be joining a small, high-impact team working across the company’s hardware and cloud platforms to keep people and property safe.

What You’ll Do

• Design and build low-latency, high-availability backend services that orchestrate alarm detection and response
• Create flexible and extensible AI-powered workflows for intrusion and video monitoring use cases
• Build distributed systems that integrate internal products and third-party services (e.g., notifications, transcription, dispatch)
• Collaborate closely with product managers, designers, frontend, and firmware engineers to shape end-to-end customer experiences

What You Bring

• 1-3 years of backend engineering experience in a production environment
• Strong programming skills-Go preferred
• Solid grasp of distributed system design, API architecture, and event-driven workflows
• Background working with databases (e.g. Postgres) and scalable data systems (e.g. Kafka, Redis)

Bonus Points

• Familiarity with Temporal or other workflow engines
• Experience developing AI-based systems capable of real-time reasoning from video and audio inputs.
