Software Engineer (Go / AWS, IoT Device Integration)

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 work goes beyond connecting any single device: you'll help build the abstractions and patterns that bring a growing ecosystem of devices online reliably through cloud-to-cloud API and event-driven integrations. This is a Go/AWS-first role: net-new development is in Go, and you'll implement integrations, contribute to the platform patterns the team is establishing, and own components end-to-end as the team grows., * Design and build scalable, high-concurrency backend services in Go on AWS (Lambda, EC2, DynamoDB, SNS/SQS, SSM)

• Implement integrations with external cloud platforms via APIs and event/callback models - working with auth/token lifecycle, API contracts and versioning, and rate limits - contributing to the frameworks and patterns that make onboarding repeatable
• Work with core device-platform concepts - device identity, capabilities, commands, events, state synchronization, and onboarding/deprovisioning - as you build and operate integrations
• Contribute to mapping device capabilities into our platform, working with technical and business teams
• Build resilient, event-driven integrations on top of third-party systems - handling async event processing, idempotency, retries, partial failure, and state reconciliation
• Provide maintenance and support for our existing Java/Spring Boot platform during an ongoing transition, while net-new development is Go/AWS-first
• Contribute to performance tuning, reliability, and observability improvements
• Build and ship using AI-assisted development tools as part of day-to-day engineering
• Participate in architecture and design discussions
• Take ownership of features and components end-to-end

• 5+ years of backend software engineering experience
• Solid backend engineering skills in a statically typed language such as Java or Go (we are Go-first going forward; willingness and ability to ramp to Go required)
• Hands-on experience with AWS cloud-native services (Lambda, EC2, DynamoDB, SNS, SQS)
• Solid understanding of distributed systems, concurrency, and scalability
• Experience with CI/CD pipelines and GitHub Actions
• Experience operating production services (participating in on-call, monitoring, incident response)

Preferred Qualifications

• Experience with Infrastructure as Code (Terraform)
• Production Go experience
• Exposure to 3rd-party API/device integration or IoT
• Experience integrating external cloud platforms or SaaS APIs (auth/token lifecycle, webhooks/callbacks, rate limits)
• Experience with event-driven architectures and asynchronous messaging (e.g., SNS/SQS, queues, streams, pub/sub)
• Prior IoT or device-platform experience
• AWS certification is a plus, though hands-on production experience matters more
• Experience using AI-assisted development tools
• Strong cross-functional communication skills
• Experience with Spring Boot or Micronaut
