Senior Site Reliability Engineer

About the role

Goodnotes, part of Good Systems, is hiring a Senior SRE to join the founding SRE team for New Goodnotes, its next-generation flagship product. You will own its operational quality: how reliably it runs, how well it performs, how early problems are spotted and how quickly issues are recovered. You will work closely with Product and Platform Engineers, and help build an agentic SRE approach from the ground up.

Key responsibilities

• Define availability, reliability and performance objectives with the engineering teams, using service-level objectives and error budgets.
• Build observability: instrumentation, dashboards and actionable alerts that surface problems early.
• Investigate failure modes and make changes to application code, infrastructure and architecture that improve resilience and recoverability.
• Build the tools, execution environment and runbooks for an agentic SRE platform, with permissions, audit trails, rollback and escalation.
• Join the on-call rotation as a first responder, coordinate recovery and communicate clearly.
• Turn incidents and near misses into improvements, and replace repetitive manual work with software and automation.
• Help establish production readiness and operational practices with engineers across the Global and Shanghai teams.

Required profile

• Significant experience in SRE or a similar role, operating production software at scale with a large engineering organisation.
• Strong software engineering skills, including reading unfamiliar code, diagnosing production behaviour and implementing tested changes.
• Hands-on experience designing, operating and troubleshooting production systems on AWS.
• Experience defining reliability objectives, building observability with metrics, logs and traces, and responding to production incidents.
• Practical use of AI tools in engineering, and a strong sense of ownership and communication.

Required skills

• AWS
• Distributed systems, networking and databases
• Metrics, logs and traces; observability
• AI tools in the engineering workflow
• Nice to have: AI agents, infrastructure as code (Pulumi), Kubernetes, OpenTelemetry, ClickHouse or ClickStack, and experience building a new SRE team

What we offer

• Stipends for training, personal development, health and wellness and equipment such as noise-cancelling headphones.
• Sponsored visits to office locations and annual company-wide offsites.
• Premium medical insurance for you and a dependent.
• Hybrid work: 4 days in the office and 18 remote days per year.

The interview process includes a talent intro call, a short technical pre-screen, an AI-assisted take-home challenge, onsite technical and values-based interviews, and a meeting with an AI champion. Background checks are required.
