Job Summary About the Role: We’re the Camera Platform team, powering the backend for the video devices in our Smart Home / Connected Living organization.

As Smart Home rapidly expands its lineup of connected devices, our charter is growing with it: we’re building the platform that turns 3rd-party device onboarding from a series of bespoke integrations into a repeatable, scalable capability — enhancing home security and peace of mind for Comcast customers.

The hard problem isn’t connecting any single device; it’s designing the abstractions, frameworks, and patterns that let us bring an entire ecosystem of diverse devices online quickly and reliably through cloud-to-cloud API and event-driven integrations, each partner with its own APIs, auth models, and capabilities.

This is a Go/AWS-first role: net-new development is in Go, and you’ll help set the technical direction for a growing team as it takes shape — working directly with device partners and internal teams to shape how their capabilities map into our platform.

Job Description What You’ll Do Design and build the platform, frameworks, and abstractions that make 3rd-party device onboarding repeatable, scalable, and reliable Lead architecture and design for integrating external cloud platforms via APIs and event/callback models — including auth/token lifecycle, API contracts and versioning, rate limits, and operational support boundaries Design the device-platform abstractions behind these integrations: device identity, capabilities, commands, events, state synchronization, onboarding/deprovisioning, and lifecycle management Partner with external device vendors and internal technical and business teams to understand new devices and define the strategy for mapping their capabilities into our platform Design and build scalable, high-concurrency backend services in Go on AWS (Lambda, EC2, DynamoDB, SNS/SQS, SSM) Build resilient, event-driven integrations on top of third-party systems — handling async event processing, idempotency, retries, partial failure, backpressure, and state reconciliation Own end-to-end delivery: design, implementation, rollout, and operations Provide maintenance and support for our existing Java/Spring Boot platform during an ongoing transition, while net-new development is Go/AWS-first Build and ship using AI-assisted development tools as part of day-to-day engineering Set standards for observability, reliability, and operational excellence Mentor engineers and guide technical decision-making across the team Required Qualifications 7+ years of backend software engineering experience Strong backend engineering fundamentals in a statically typed language such as Java or Go (we are Go-first going forward; strong engineers without Go experience are welcome if able to ramp quickly) Hands-on experience building and operating cloud-native systems on AWS (Lambda, EC2, DynamoDB, SNS, SQS, SSM) Proven experience designing distributed systems and high-concurrency, low-latency services Strong system design fundamentals: concurrency, scalability, and performance optimization Experience with Infrastructure as Code (Terraform) Experience with CI/CD pipelines and GitHub Actions Hands-on experience operating production services (on-call, incident response, monitoring/alerting) Proficiency with AI-assisted development tools (e.g., coding assistants/agents) and good judgment about where they help Strong communication and cross-functional collaboration skills, with experience working across technical and business teams to align on requirements and approach Ability to navigate ambiguity and define technical strategy where the path isn’t predetermined Track record of owning systems end-to-end in production Preferred Qualifications Experience integrating 3rd-party devices, APIs, SDKs, or hardware/IoT protocols Experience integrating external cloud platforms or SaaS APIs (auth/token lifecycle, API versioning, rate limits, webhooks/callbacks) Experience with event-driven architectures and asynchronous messaging (e.g., SNS/SQS, queues, streams, pub/sub) Production Go experience Prior IoT or device-platform experience AWS certification is a plus, though hands-on production experience matters more Experience with Spring Boot or Micronaut Disclaimer: This information has been designed to indicate the general nature and level of work performed by employees in this role.
