Job Summary

The Telco Cloud Core Architect & Automation and services is responsible for defining and driving the architecture of the cloud-native core platform while shaping the company’s API strategy to enable scalable, secure, and interoperable services. This role ensures alignment between cloud infrastructure, 4G/5G core evolution, digital platforms, and API products—enabling faster innovation, improved service exposure, and ecosystem growth. The role collaborates with Engineering, TechCo, Product, IT/Digital, Cybersecurity, and external partners to build an architecture that accelerates digital services, supports network modernization, and unlocks new monetization opportunities through APIs.

Key Responsibilities

• Design and govern cloud-native core architecture (EPC, IMS, 5G Core, UDM, PCF, NEF).
• Maintain a stable, scalable cloud-native core platform.
• Define architecture patterns for CNFs/NFVs (e.g., OpenStack, Kubernetes), network slicing, edge cloud, and distributed compute.
• Deliver complete target-state and transition-state architecture maps aligned to the technology roadmap.
• Create long-term roadmap and implementation plans for telco cloud infrastructure.
• Ensure strategic alignment and modernization readiness.
• Define the company’s API strategy covering network APIs (NEF, CAPIF/3GPP, CAMARA), enterprise APIs (B2B exposure), and internal service APIs for microservices.
• Align with GSMA Open Gateway standards.
• Lead API governance, standards, and lifecycle management (design, versioning, documentation, deprecation).
• Ensure consistent API governance and high adoption across internal and partner ecosystems.
• Oversee API gateways, service mesh, identity, and access frameworks (OAuth2, OIDC, mTLS).
• Operate a robust, secure, and scalable API platform supporting telco API monetization.
• Partner with product teams to translate network capabilities into monetizable APIs.
• Faster launch of network and digital services.
• Drive automation (IaC, CI/CD, GitOps) and cloud reliability (SRE, observability).
• Reduce time for changes through optimized CI/CD workflows.
• Ensure platform security, compliance, resilience, and Zero Trust principles.
• Implement Zero Trust controls across identity, workload, and network layers with full policy coverage.
• Maintain architecture blueprints, reference models, and decision records.
• Publish and update architecture blueprints quarterly with version control and stakeholder sign‑off.
• Lead vendor evaluation, architecture reviews, and technology roadmaps.
• Conduct Architecture Review Boards with ≥90% project compliance to standards.
• Complete vendor evaluations with standardized scoring, benchmarks, and TCO for 100% major procurements.

Skills

• Strong experience in cloud-native telco core (EPC, 5G Core SA, IMS, UDM, PCF, NEF).
• Deep expertise in Kubernetes, containers, service mesh (Istio/Linkerd), and distributed systems.
• Strong understanding of API frameworks (REST, gRPC), gateways, OAuth2, OIDC, JWT, rate limiting, throttling.
• Familiarity with GSMA Open Gateway / CAMARA and CAPIF architecture.
• Proficiency with IaC (Terraform, Ansible), CI/CD, GitOps.
• Strong grasp of cloud networking (BGP, CNI, overlay networks).
• Understanding of SRE practices and cloud observability stacks (Prometheus, Grafana, ELK, Jaeger).

Leadership Competency

• Technology Vision – Shapes cloud-native evolution roadmap; defines cloud stack direction for on‑prem telco core workloads.
• Innovation & Automation – Drives automation in operations; delivers scalable, resilient, and cost-effective cloud infrastructure.
• Execution Oversight – Ensures timely delivery of infrastructure goals; tracks infra delivery milestones, issue resolution, and performance optimization.
• API Strategy Leadership – Leads API enablement and adoption; develops robust frameworks for telco API infrastructure and exposure.
• Stakeholder Engagement – Collaborates across teams and vendors; drives alignment and smooth integration across domains and suppliers.
• Operational Discipline – Ensures system stability and compliance; embeds governance, monitoring, and security standards.
• Infrastructure Strategy – Guides hardware and orchestration technology choices; selects optimal platform combinations for performance, efficiency, and cost.

Qualifications

• Bachelor’s or master’s degree in computer science, electrical engineering, or related technical field.
• 8–15+ years in network/cloud architecture or platform engineering.
• Hands‑on experience with large-scale cloud-native telco systems.
• Experience designing or leading API ecosystems (internal or external).
• Proven leadership in multi‑vendor, cross‑functional environments.
• Experience initiating or leading AI-based network operations and automation projects in cloud, SDN, or telco core domains.
• Familiarity with multi-vendor telco environments, open-source ecosystems, and hardware platform benchmarking.
