Remote — Kraków, Lesser Poland Voivodeship, pl · Posted 9h ago
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
- Support the deployment, operation, and reliability of production services running on Kubernetes.
- Monitor service health and investigate production incidents across distributed applications.
- Participate in on-call support, incident response, root cause analysis, postmortems, and reliability improvements.
- Troubleshoot application runtime, networking, and service-to-service issues in collaboration with engineering teams.
- Support CI/CD, GitOps-based deployments, observability, and production monitoring.
- Work within a client-directed backlog and established priorities.
Expectations – the experience you need
- 5+ years of experience in Site Reliability Engineering, DevOps, Platform Engineering, Production Engineering, or a closely related role, including strong recent hands-on experience supporting Kubernetes-based production services.
- 3+ years of hands-on production Kubernetes experience strongly preferred. Kubernetes production operations, including deployment, scaling, rollout / rollback, resource tuning, and service-to-service troubleshooting
- Strong production incident response experience, including on-call, runbooks, postmortems, and paging hygiene
- Splunk experience for log aggregation, search, and production troubleshooting
- Prometheus and Grafana experience, specifically building alert rules and dashboards, not only using existing dashboards
- CI/CD and infrastructure-as-code for containerized deployments, including Helm and GitOps tools such as ArgoCD or Flux
- Strong Linux and networking fundamentals, including DNS, load balancing, TCP / HTTP, HTTP/2, and Kubernetes networking
- Production troubleshooting experience across Node.js and JVM/Java services, with strong depth in at least one runtime environment. Experience may include Node.js heap snapshots, CPU profiling, event-loop and memory analysis, as well as JVM GC log analysis, thread dumps, JVM tuning, and Java service latency investigation.
- Service-to-service authentication experience, including mTLS, certificate rotation, certificate format conversion, and JWT-based service authentication
- Very good spoken and written English.
Additional skills – the edge you have
- Web Components / Lit experience, to perform first-level debugging of UI-related issues
- Server-side rendering or isomorphic runtime experience
- Canary rollout / multi-version production operations
- Distributed tracing and request-context correlation
- KEDA or event-driven autoscaling
- Experience with enterprise platform integration layers
Our offer – professional development, personal growth:
- Flexible employment and remote work
- International projects with leading global clients
- International business trips
- Non-corporate atmosphere
- Language classes
- Internal & external training
- Private healthcare and insurance
- Multisport card
- Well-being initiatives
