Senior Software Engineer

Requirements Must have We want proven experience running production cloud services at scale, including monitoring, alerting, incident response, post-incident reviews, and ongoing reliability improvements. We are looking for strong troubleshooting ability in distributed systems, with hands‑on experience using observability tools such as Prometheus, Grafana, OpenTelemetry, and distributed tracing. We need experience building and operating Kubernetes controllers that work with the API server, including resolving reconciliation issues, handling API rate limits, and improving controller efficiency. We value comfort in working directly with customers to understand, reproduce, and fix complex technical problems in their environments. We expect ownership and accountability for solving problems beyond your immediate scope, especially during incidents that affect customer workloads. We look for a commitment to high‑quality work and a continuous drive to strengthen your skills and the operational resilience of the systems you build. We seek customer empathy, with an understanding that reliability and debuggability are core product features. We need clear communication and strong collaboration skills to work effectively as a team and support customers through technical challenges. We value a team‑oriented mindset that helps create a safe environment where people can contribute, learn from failures, share on‑call knowledge, and grow as engineers and operators. Responsibilities We will have you build and operate Upbound Spaces in production, resolving issues across multi‑tenant SaaS environments and contributing to our open‑source work, including Crossplane. We will ask you to own high‑priority features requested by our customers and deliver new capabilities that improve their experience. We will have you investigate and debug complex customer‑side issues, including multi‑control‑plane scenarios, reconciliation failures, and performance constraints. We will expect you to produce thoughtful design documents for new initiatives and detailed post‑incident reviews that inform future improvements. We will have you support the full lifecycle of highly scalable, reliable cloud services, from discovery and architecture through deployment and ongoing operations. We will rely on you to write and maintain Go code that interfaces with the Kubernetes API, with an emphasis on observability, debuggability, and operational excellence. We will have you deploy, manage, and troubleshoot our Kubernetes services in production using metrics, logs, and traces. We will ask you to build and maintain operational tooling for customer debugging, control plane health analysis, and incident‑response automation. We will have you create documentation, user guides, runbooks, and blog posts that support and promote the features you ship. We will expect you to support the release process for our self‑hosted Spaces distributions, including diagnosing issues in customer‑managed environments. We will have you participate in an on‑call rotation for Upbound Cloud and help resolve incidents end to end.
