Job Description
Project – the aim you'll have
We are the AI Experience Framework team that builds the platform powering ServiceNow's AI-first user interfaces - an SSR runtime (karuna) built on Lit and server-rendered web components, running behind a multi-tier proxy/HTTP2 routing chain with sharded V8 isolate pools, paired with a ServiceNow Glide/Java platform layer (karuna-glide) that supplies metadata, ACLs, and service artifacts. This role owns production reliability for that stack end to end: Kubernetes deployment and operations, observability, and hands-on troubleshooting of both the Node.js and JVM sides of the system - not generalist infrastructure work.
Position – how you’ll contribute
- Own Kubernetes deployment and operational health for Framework services, including scaling, rollout/rollback strategy, and resource tuning
- Build and maintain production observability - Grafana dashboards and Prometheus alerting rules - across the SSR runtime and the Glide platform layer
- Diagnose and resolve Node.js production incidents: event-loop stalls, heap growth, V8 isolate exhaustion, and isolate-pool scheduling issues under concurrent versioned traffic (vN/vN-1)
- Diagnose and resolve JVM production incidents on the Glide/Java side: GC pressure, thread dumps, and platform-service latency
- Own incident response for the team: runbooks, on-call rotation, postmortems, and paging hygiene
- Drive CI/CD and infrastructure-as-code for Kubernetes manifests/Helm and deployment pipelines
- Partner with the framework engineering team to identify reliability gaps before they become incidents - capacity planning, load testing, chaos/failure-injection where useful
- Represent production reliability concerns in architecture reviews for new framework capabilities
Qualifications
Expectations – the experience you need
- Production operations/SRE experience, including hands-on Kubernetes deployment, scaling, and incident response
- Direct operational experience troubleshooting Node.js in production: reading heap snapshots and CPU profiles, diagnosing event-loop blocking, and understanding process/worker isolation models (V8 isolates or equivalent sandboxing)
- Direct operational experience troubleshooting JVM-based services in production: GC log analysis, thread dump analysis, and JVM tuning
- Hands-on experience building and maintaining Prometheus alerting rules and Grafana dashboards from scratch, not just consuming existing ones
- Strong Linux/networking fundamentals: DNS, load balancing, TCP/HTTP semantics (including HTTP/2), and debugging service-to-service networking inside Kubernetes
- Experience with CI/CD and infrastructure-as-code for containerized deployments (Helm, GitOps tooling such as ArgoCD/Flux, or equivalent)
- Track record owning on-call rotations, writing runbooks, and driving postmortems that lead to real reliability improvements
- Experience with Splunk for log aggregation, search, and production troubleshooting.
- Hands-on experience with in-memory caching systems (Valkey/Redis) in production — key design, TTL/eviction tuning, and tenant-scoped cache invalidation
- Experience managing service-to-service mTLS - certificate issuance, rotation, and format conversion (e.g., PKCS/BCFKS↔PEM) - plus JWT-based service authentication
- Very good spoken and written English.
Additional skills – the edge you have
- Familiarity with server-side rendering architectures and the specific failure modes of isomorphic runtimes (markup mismatches, browser-API leakage into server code)
- Experience operating multi-version/canary rollout strategies (two live app versions served concurrently)
- Working knowledge of the ServiceNow Glide platform or a comparable enterprise platform integration layer
- Experience with distributed tracing and request-context correlation across service boundaries
- Familiarity with event-driven autoscaling (e.g., KEDA ScaledObjects driven by PromQL triggers) as a complement to standard HPA-based scaling
