Preferred * Experience building and operating SaaS products. * Experience with CI/CD systems (GitHub Actions, Jenkins, etc.) and monitoring/observability tooling (Prometheus, Datadog, etc.). Wondering if you're a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams - even if you aren't a 100% skill or experience match. Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk. * You love designing and operating backend services that scale gracefully under pressure. * You're curious about reducing on-call burden through better architecture rather than more heroics. * You're an expert in building critical services on a Go, Kubernetes, Terraform, and PostgreSQL stack. ## Description The AI Dev Platform Tooling team builds and operates the SaaS platform that lets our engineers ship software quickly, reliably, and safely. We own the deployment automation, infrastructure provisioning and monitoring, and release systems - built on a Go, Kubernetes, Terraform, and PostgreSQL stack - that underpin our engineering organization's ability to deliver software to customers across GCP, AWS, Azure., We are seeking a Senior Software Engineer to design, build, and operate the backend services and APIs at the core of our SaaS infrastructure. This is primarily a backend software engineering role: you'll write Go running on Kubernetes, manage state in PostgreSQL, and provision infrastructure with Terraform across multiple public clouds. You'll evolve designs to meet increasingly challenging scale, stability, and performance demands, and own large, ambiguous problems end to end. We care deeply about a sustainable on-call culture, so you'll participate in on-call rotations while championing the architecture that reduces on-call burden over time. In this role, you will: * Design, build, deploy, and operate critical backend services and APIs that power our SaaS infrastructure across AWS, GCP, Azure, and customer-managed environments. * Treat API design as a first-class concern, defining clean, durable interfaces that internal and external consumers depend on. * Evolve system designs to meet increasingly challenging scale, stability, and performance requirements. * Break down and solve large, ambiguous problems, turning them into well-scoped, shippable engineering work. * Reduce on-call burden through better architecture, automation, and observability - and participate in on-call rotations. * Provide technical leadership and mentorship, work alongside Principal Engineers, and influence the broader technical direction of the platform. * Contribute to frontend web clients where it accelerates the team (a plus, not a requirement). ## Related Videos - [Our GitOps approach for deploying an Identity Provider and an API Gateway in a SaaS company](https://www.wearedevelopers.com/videos/776-our-gitops-approach-for-deploying-an-identity-provider-and-an-api-gateway-in-a-saas-company) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [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 Road to MLOps: How Verivox Transitioned to AWS](https://www.wearedevelopers.com/videos/1050-the-road-to-mlops-how-verivox-transitioned-to-aws) - [Retooling and refactoring - an investment in people.](https://www.wearedevelopers.com/videos/371-retooling-and-refactoring-an-investment-in-people) - [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 - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [What Makes WeAreDevelopers World Congress Different From Every Other Tech Event?](https://www.wearedevelopers.com/magazine/701-what-makes-wearedevelopers-world-congress-different-from-every-other-tech-event) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How to Answer the Interview Question: “Why Do You Want to Be a Software Engineer?”](https://www.wearedevelopers.com/magazine/392-how-to-answer-the-interview-question-why-do-you-want-to-be-a-software-engineer)
