- Kubernetes: Production experience with K8s, Helm, Ingress, autoscaling, network policies, and resource management.
- CI/CD: Proficiency in GitHub Actions, GitLab CI, or Jenkins.
- Observability: Hands-on experience with Prometheus + Grafana, logging (Loki/ELK), and tracing (OpenTelemetry/Jaeger).
- AI Infrastructure: Experience with GPU clusters and ML stacks (NVIDIA drivers, CUDA, MIG, GPU monitoring).
- Data Stores: Production-level operation of Postgres, Redis, Kafka, or RabbitMQ.
- Security First: Practical knowledge of Vault, KMS, RBAC, OPA/Gatekeeper/Kyverno, Trivy, and SBOM.

- AI Serving: Triton, vLLM, custom inference services
Responsibilities
- 1. AI / MLOps (Production for Models)
- GPU Infrastructure: Deploy and maintain high-performance GPU clusters.
- AI Lifecycle: Manage the full lifecycle of AI services: inference deployment (Triton, vLLM, custom services), autoscaling, and seamless rollout/rollback strategies.
- Data Management: Manage model storage, artifact versioning, caching, and high-speed data access via S3-compatible storage.
- Observability: Monitor performance metrics including latency, throughput, error budgets, resource limits, and cost/performance ratios.
- 2. PSP / Fintech Reliability
- High Availability: Ensure fault tolerance for payment services (SLA/SLO management, redundancy, Disaster Recovery planning, and regular recovery testing).
- Fintech-Grade Security: Implement secrets management, HSM/managed KMS integration, infrastructure hardening, and audit logging.
- Secure CI/CD: Build secure pipelines featuring artifact signing, vulnerability scanning, policy gates, and isolated environments.
- 3. Crypto Infrastructure
- Node Operations: Deploy and maintain crypto nodes (Full, Archive, RPC) across various networks.
- Automation: Automate node updates, synchronization monitoring, and health checks.
- Storage & Performance: Manage disk I/O (IOPS/RAID), protect RPC endpoints, and manage access controls.
- Metrics: Monitor for sync lags, chain forks, and consensus issues.
