Senior Infrastructure & Platform Engineer

Job Summary

The Senior Infrastructure & Platform Engineer manages and executes the deployment, configuration, and technical validation of enterprise applications across multi-vendor infrastructure stacks. Core daily tasks include authoring Low-Level Design (LLD) topologies, translating project blueprints into explicit network, server, and database provisioning requests, resolving complex cross-layer connectivity and host issues, auditing compliance against security frameworks, and routing system changes through automated ServiceNow ticketing workflows.

Required Professional Experience & Architectural Background

• Enterprise Experience: Proven track record operating successfully as an Infrastructure Engineer, Systems Engineer, Technical Infrastructure Engineer, or a closely matching corporate infrastructure delivery role.
• Environment Depth: Deep, demonstrable understanding of enterprise IT infrastructure architectures, featuring significant hands-on experience navigating complex, multi-site on-premises data center environments.
• Hosting Frameworks: Comprehensive grasp of modern application architectures, including how multi-tier enterprise applications are hosted, connected across firewalls, load-balanced, and operationally maintained.
• Design Blueprinting: Solid experience creating, interpreting, and engineering directly from complex Low-Level Design (LLD) infrastructure topologies and technical integration documents.

Required Systems Coordination & Execution Skills

• Vetting & Gathering: Proven ability to analyze poorly defined project descriptions, interview application owners, extract exact technical requirements, and consolidate inputs into concrete implementation steps.
• Request Life Cycle Management: Extensive experience initializing, detailing, and tracking complex infrastructure, network routing, server configuration, database provisioning, and identity access requests through to formal closure.
• Cross-Team Collaboration: Natural comfort collaborating horizontally with isolated infrastructure domains, including Linux/Windows host management, network operations, database administration, and corporate cybersecurity groups.
• Multi-Tasking Execution: Outstanding organizational skills, characterized by the ability to manage multiple concurrent deployment requests and infrastructure projects smoothly without losing detail or velocity.

Broad Multi-Domain Technical Knowledge (Expertise in all is not required)

The successful candidate must possess broad technical credibility and conversational fluency across a combination of the following enterprise technologies:

• Compute & Virtualization: VMware vSphere environments, Windows Server administration, and enterprise Linux distributions (RHEL/CentOS).
• Networking & Firewalls: Enterprise Software-Defined Networking platforms (e.g., Cisco ACI), next-generation firewalls (Fortigate), and Secure Access Service Edge architectures (CATO Networks).
• Application Delivery & Load Balancing: Traffic management systems like NetScaler and enterprise virtual desktop infrastructure (Citrix Virtualisation).
• Storage Architectures: Network-Attached Storage (NAS) and Storage Area Network (SAN) operations, specifically utilizing NetApp storage systems.
• Identity & Access Management: Traditional Active Directory design alongside modern cloud identity platforms like Entra ID.
• Containerization & Cloud Fabrics: Modern microservice platforms (OpenShift), cloud native services (Azure App Services), and API orchestration layers (Azure API Management).
• Automation, Monitoring & ITSM: Infrastructure-as-Code engines (Ansible), open-source monitoring suites (Grafana), and institutional workflow managers (ServiceNow).

Key Responsibilities

1. Low-Level Technical Topology Design & Requirement Synthesis (35%)

• Translate Application Blueprints: Review incoming application architecture designs and translate high-level business goals into explicit, actionable infrastructure configurations.
• Architect Low-Level Topologies: Draft comprehensive, highly detailed low-level technical topologies (LLD), explicitly mapping server host placements, VLAN allocations, load-balancing VIPs, and storage tier assignments.
• Extract Deployment Variables: Interview software engineering groups and project leads to pull hidden resource dependencies, capacity projections, and connectivity profiles from scattered sources.
• Standardize System Documentation: Build and preserve a centralized, audit-ready inventory of deployment requirements, storage allocations, firewall rule exceptions, and architectural decisions.

2. Full-Stack Infrastructure Provisioning & Request Governance (30%)

• Initialize Enterprise Requests: Translate approved LLD designs into formal infrastructure change sets, opening precise compute, network routing, database instance, and access control modifications via ServiceNow.
• Drive Request Pipelines: Monitor and advance active infrastructure requests through internal approval tracks, following up directly with core network, storage, or security teams to prevent operational bottlenecks.
• Manage Change Configurations: Ensure all infrastructure modifications are logged, reviewed, and deployed in strict accordance with corporate version control guidelines and standard change windows.
• Audit Compliance Frameworks: Verify that every server build, database instance deployment, and firewall rule change aligns perfectly with internal security profiles and corporate data privacy standards.

3. Multi-Domain Technical Troubleshooting & Coordination (25%)

• Triage Deployment Roadblocks: Serve as the primary point of contact for technical triage when application deployments encounter configuration errors, storage dropouts, or database performance limits.
• Isolate Connectivity Failures: Use advanced network diagnostic logic to trace application packets across internal firewalls (Fortigate), software-defined fabrics (Cisco ACI), and load balancers (NetScaler).
• Orchestrate Crisis Resolution: Confidently bring together specialized technical experts, platform engineers, and external vendor support teams to resolve critical, hard-to-pinpoint systemic bugs.
• Mitigate Deployment Risk: Proactively identify, track, and document cross-platform resource contentions, structural single points of failure, and security risks during major migration phases.

4. Strategic Hosting Consulting & Operational Readiness (10%)

• Guide Strategic Hosting Discussions: Act as an expert guide in cross-departmental reviews focusing on compute hosting options, data residency constraints, security measures, and high-availability setups.
• Guarantee Operational Hand-off: Coordinate the formal transition of newly deployed applications into standard operations, ensuring logging agents, Grafana dashboards, and backup policies are fully live.
• Mentor Engineering Teams: Provide continuous technical guidance and system training to junior engineers and application teams, driving overall operational consistency across the Chennai engineering center.

Core Competencies & Skills

• Multi-Domain Engineering Vision: The rare ability to maintain high technical credibility across completely different infrastructure spaces—from raw storage arrays to cloud API layers.
• Analytical Rigor & Investigation: A sharp, inquisitive mind that actively challenges ambiguous system definitions and digs into raw logs to find hidden dependencies.
• Dynamic Crisis Orchestration: Exceptional leadership and communication skills, enabling you to guide high-pressure troubleshooting calls and keep diverse technical teams focused on the root cause.
• Delivery-Focused Execution: A practical, outcome-driven mindset that takes personal accountability for navigating complex corporate systems and seeing work through to completion.
