Job Description

Key Responsibilities

·         Lead end-to-end delivery of network automation and IaC initiatives across enterprise environments.

·         Design scalable automation solutions for network provisioning, configuration, policy enforcement, drift detection, and compliance reporting.

·         Develop and maintain Python-based automation frameworks, reusable libraries, utilities, and tooling (logging, validation, retries, reporting).

·         Build and standardize IaC patterns using Terraform and Ansible (modules, roles, collections, inventories).

·         Implement model-driven network automation using NETCONF and YANG (RESTCONF exposure is a plus).

·         Design Jinja template-driven configuration generation and enforce “golden configuration” standards.

·         Architect and build microservice-based network automation applications, including REST/gRPC APIs, async execution, idempotency, and retry strategies.

·         Expose automation workflows through secure APIs for provisioning, change execution, audits, and compliance checks.

·         Integrate automation workflows with CI/CD pipelines, including approvals, testing, validation, and rollback mechanisms.

·         Ensure all solutions meet security, auditability, and compliance requirements, preferably aligned with banking-grade practices.

·         Mentor engineers, conduct design and code reviews, and drive automation and engineering best practices across the team.

Required Skills

·         10–12+ years of experience in Networking / Infrastructure Engineering with a strong focus on automation.

·         Strong Python scripting expertise for network automation (API integrations, structured data, parsing, error handling, packaging).

·         Proven hands-on experience with Terraform and Ansible in production environments.

·         Practical experience with NETCONF and YANG for model-driven network automation.

·         Strong expertise in Jinja templating for configuration generation and standardization.

·         Hands-on experience designing and delivering microservice-based applications in the network or infrastructure domain.

·         Solid networking fundamentals (routing, switching, VLANs, VPNs, DNS/DHCP, load balancers, firewalls).

·         Strong Git practices and understanding of CI/CD pipelines for infrastructure and network changes.

·         Experience owning delivery or leading automation initiatives end-to-end.
