As a Software Engineer on our web platform, you will build the CMS and the automated systems that keep those surfaces reliable as we ship., * Build our CMS: Design and build the CMS workflows we need to publish and update model pages, examples, blog posts, documentation, and other website content, without a code deploy for every change. * Build automated tests: Write and maintain end-to-end, regression, and API tests for the critical product flows. These include sign-up, authentication, billing, API keys, CMS workflows, documentation, and Playground runs. * Validate the developer experience: Test API endpoints, SDKs, documentation, and code examples, so that developers can move from their first API call to a working integration. * Improve release quality: Add reliable test coverage to CI/CD and to preview deployments. Run release checks, investigate failures, and work with the engineer who owns the code to resolve them. * Monitor product health: Set up and maintain lightweight error tracking and synthetic checks, so that we find issues before customers report them. ## Related Videos - [Coffee with Developers - Adam Wiggins](https://www.wearedevelopers.com/videos/919-coffee-with-developers-adam-wiggins) - [From Doubt to Confidence: How Sentry Uses Verdaccio to Bulletproof SDK Releases](https://www.wearedevelopers.com/videos/739-from-doubt-to-confidence-how-sentry-uses-verdaccio-to-bulletproof-sdk-releases) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [The weekly developer show: Boosting Python with CUDA, CSS Updates & Navigating New Tech Stacks](https://www.wearedevelopers.com/videos/1293-the-weekly-developer-show-boosting-python-with-cuda-css-updates-navigating-new-tech-stacks) - [Debugging in the Dark](https://www.wearedevelopers.com/videos/1658-debugging-in-the-dark) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 139 - Soft and hard queries](https://www.wearedevelopers.com/magazine/487-dev-digest-139-soft-and-hard-queries) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Dev Digest 113 - Debugging above the cloud](https://www.wearedevelopers.com/magazine/422-dev-digest-113-debugging-above-the-cloud)
