System Architecture Design (Telecom)
• Design and lead scalable, fault-tolerant mediation architectures, including file ingestion, format conversion, SFTP distribution, event monitoring, and downstream delivery pipelines
• Build and maintain core mediation services using Java 17 and Spring Boot, including Spring Integration, Spring Batch, and Spring Kafka
• Contribute to shared starters and reusable platform libraries to standardize and accelerate development
• Parse, decode, and transform binary telecom data formats, including ASN.1 encoded CDRs/UDRs, AMA records, and proprietary carrier formats at the byte-stream level
• Design, deploy, and operate containerized workloads on Kubernetes and OpenShift
• Own Helm chart definitions, resource tuning, PVC strategies, horizontal scaling, and rolling upgrade policies
• Design and optimize Oracle database schemas for high volume mediation metadata, reconciliation state, and audit trails
• Write, tune, and analyze complex SQL and PL/SQL for operational reporting and performance optimization
• Define and enforce SLOs and SLIs, lead incident response, drive post mortems, and implement error budgets and auto remediation patterns
• Build production-grade observability using structured logging, distributed tracing, metrics, and alerting
• Implement and maintain monitoring stacks using ELK/EFK, OpenTelemetry, Jaeger, Prometheus, and Grafana
• Profile and optimize JVM performance, Kafka consumer throughput, file I/O pipelines, and database query patterns
• Establish performance benchmarks, regression gates, and reliability standards
• Debug and resolve system-level issues across OS, JVM, networking, file descriptors, garbage collection, and thread contention
• Design and operate Apache Kafka at scale, including partition strategies, consumer group tuning, offset management, and dead-letter handling
• Apply strong understanding of SFTP, object storage (S3-compatible), and file lifecycle management
• Collaborate with network, OSS/BSS, and downstream consumer teams to align technical solutions
• Drive architectural decisions, conduct design reviews, and mentor engineers across teams
• Apply an SRE mindset, including on-call discipline, capacity planning, and chaos engineering fundamentals
