Senior Site Reliability Engineer

Good Systems is the parent company behind Goodnotes, where millions of people capture and develop their ideas. Goodnotes is where we started, and it’s now the foundation for a growing family of products. By reimagining how we interact with information, we’re bringing together human creativity and the breakthrough capabilities of AI. We build products that help people turn good thinking into good work. Our Values Dream big • Be visionary, strategic, and open to innovation Build great things • Work in service of our users, always improving and pushing higher Operate like an owner • Take responsibility with bold decision-making and bias for action Win like a sports team • Be trusting and collaborative while empowering others Learn and grow fast • Never stop learning and iterate fast Share our passion • Share ideas and practice enthusiasm and joy Be user obsessed • Empathetic, inquisitive, practical About the role As a Senior SRE Engineer, you’ll join the founding SRE team for New Goodnotes, our next-generation flagship product. You’ll own its operational quality: how reliably it runs, how well it performs, how early we spot problems, and how effectively we recover when things go wrong. You’ll work closely with Product and Platform Engineers to set reliability goals and deliver improvements across infrastructure and application code. From investigating a production incident to fixing the underlying failure mode, you’ll take changes through to production and verify that they make the system better. You’ll also help build an agentic approach to SRE from the ground up. Our ambition is “hands-free” SRE: agents handle most routine operations, investigation and recovery, bringing in humans when judgment or intervention is needed. You’ll build the tools, execution environment and runbooks that make this possible, progressively expanding what agents can reliably do. This is an opportunity to shape a new team, establish its engineering practices, and show how a small team can operate a major product with agents doing much of the heavy lifting. This is the role for you, if you’re excited to work on the things listed below: • Owning operational quality: Define availability, reliability and performance objectives with the engineering teams. Use service-level objectives and error budgets to guide priorities and measure improvements. • Building observability that drives action: Develop instrumentation, dashboards and actionable alerts that reveal emerging problems early and help explain their impact on users. • Engineering lasting improvements: Investigate failure modes and make changes to application code, infrastructure and architecture that improve resilience, performance and recoverability. • Building an agentic SRE platform: Give agents the context and tools to investigate alerts, execute runbooks, take recovery actions and verify outcomes. Engineer clear permissions, audit trails, rollback and escalation into that execution environment. • Leading incident response: Participate in the on-call rotation as a first responder for New Goodnotes. Coordinate recovery, communicate clearly and involve the right engineers when needed. • Learning from production: Turn incidents and near misses into improvements to the system, its observability and the agents operating it. • Reducing operational toil: Replace repetitive manual work with software and automation, increasing the proportion of operations agents can complete successfully. • Shaping how the team works: Establish production readiness and operational practices alongside engineers across our Global and Shanghai teams, and influence technical decisions through clear reasoning and evidence. The skills you will need to be successful in the above: • Significant experienc
