Software Engineer AWS Lambda

What if firmware engineers never had to wait for a build again? We're a software development team at Ring, based in Poland, who also own the entire CI/CD platform behind Ring's firmware. We design and build the systems that compile, test, and deliver firmware to millions of smart home devices — and we write purpose-built software to do it: cloud-native services, infrastructure-as-code, AI-powered automation, and developer tools that hundreds of engineers rely on daily.
We're currently building an AI-driven platform that uses agentic workflows to fundamentally change how code gets reviewed, built, and tested. We're also scaling cloud build fleets across large compute clusters, optimizing distributed caching for embedded builds, and replacing legacy systems with modern, fully automated pipelines. If you want to write software that makes other engineers dramatically more productive, we'd love to talk.
As a bonus — we've built our own AI-powered assistant that lives in our Slack workspace and helps the team with everything from answering developer questions to writing its own code. You'll be working alongside it from day one.
Building cloud-native services and automation that power CI/CD for Ring's entire firmware product lineup

• Designing and implementing infrastructure-as-code (CDK/TypeScript) to manage build fleets, pipelines, and deployment workflows on AWS
• Working with AWS services (CodeBuild, Step Functions, Lambda, ECR, EFS) to scale build infrastructure that handles thousands of daily builds
• Building observability dashboards and monitoring to give the team and stakeholders clear visibility into system health and performance
• You start your morning catching up on overnight build results and checking observability dashboards. A nightly build hit a strange failure on a new platform — you ask your AI assistant to dig into the logs and trace the issue, then push a fix through the team's own CI pipeline before lunch. In the afternoon, you prototype a feature for the team's AI-powered build platform — maybe teaching it to detect flaky tests or predict build failures. You wrap up the day reviewing a code change that lets developers manage their CI configuration through a simple commit instead of a ticket.

We're the Ring's firmware build services and developer tools group, based in Poland. We own the tools, data, and infrastructure that move code from developer laptops to customer devices, and we're focused on making that journey as smooth as possible.
We build everything from CI orchestration platforms and build fleet managers to AI-powered automation and monitoring systems. Our tech stack spans TypeScript, Python, and AWS cloud services — we write software, deploy through our own pipelines, and use our own tools daily. Our vision is a suite of integrated tools that covers the entire development lifecycle, from pre-hardware development all the way to production.
