As a Senior Software Engineer on the Camera Platform team within the Smart Home/Connected Living organization, you will design and build scalable backend services in Go on AWS to facilitate seamless integration of third-party devices into our ecosystem. Your day-to-day responsibilities include leading architecture for cloud-to-cloud API integrations, designing device-platform abstractions, and ensuring reliable event-driven integrations with external systems. You will work closely with internal teams and external partners to map new devices onto the platform while maintaining existing Java/Spring Boot services during a transition period. Essential skills include hands-on experience with AWS services like Lambda, EC2, DynamoDB, and SNS/SQS, as well as proficiency in AI-assisted development tools and strong system design fundamentals. This role demands expertise in distributed systems, high-concurrency service design, and operational excellence to enhance home security through scalable device integration solutions.
Design and build scalable, high-concurrency backend services in Go on AWS.
Lead architecture for integrating external cloud platforms via APIs and event-driven models.
Develop device-platform abstractions including identity, capabilities, commands, and lifecycle management.
Mentor engineers and guide technical decision-making across the team.
Build resilient integrations with third-party systems using async processing and state reconciliation.
What we're looking for
7+ years of backend software engineering experience with strong fundamentals in statically typed languages like Java or Go.
Extensive hands-on experience building and operating cloud-native systems on AWS, including Lambda, EC2, DynamoDB, SNS/SQS/SSM.
Proven track record designing distributed systems and high-concurrency, low-latency services with expertise in concurrency, scalability, and performance optimization.
Proficiency in Infrastructure as Code (Terraform) and CI/CD pipelines, including GitHub Actions.
Strong experience operating production services, including on-call responsibilities, incident response, monitoring, and alerting.
Ability to navigate ambiguity and define technical strategy while owning systems end-to-end in production.
