Job description

ZYBISYS CONSULTING SERVICES LLP | Full time

Zybisys is a technology company that helps banks, financial institutions, and FinTech businesses build and run secure, reliable, and high-performance technology platforms. We work closely with some of India's leading stock brokers to manage their cloud infrastructure, cybersecurity, platform operations, and observability. With deep expertise in the Capital Markets domain, we focus on simplifying complex technology, improving operational resilience, and helping our customers innovate with confidence.

Job Description

The Specialist Engineer is a senior Subject Matter Expert (SME) role within the Zybisys Managed Cloud Services practice. This position carries deep technical ownership across critical platform domains — network security, cloud traffic management, identity and access, observability engineering, and storage infrastructure — spanning a complex multi-region Azure and hybrid datacenter environment.

Unlike generalist operations roles, the Specialist Engineer is the definitive technical authority within their domain. They design and architect platform solutions, lead complex implementations, serve as the L3 escalation point beyond L2, guide and upskill the operations team, and drive continuous platform improvement. The ideal candidate has hands‑on mastery of multiple technology stacks and can move fluidly between deep technical problem‑solving and stakeholder‑facing architecture discussions.

Key Responsibilities

• Serve as the definitive technical escalation point (L3) for complex incidents that exceed L2 capability — owning the problem through to permanent resolution.


• Provide expert‑level analysis and diagnosis across assigned technology domains: network security platforms, Azure cloud services, observability stacks, and identity infrastructure.


• Lead post‑incident technical reviews for high‑severity events, producing architecture‑level RCA reports that identify root cause, systemic risk, and strategic remediation steps.


• Act as the technical advisor to the Cloud Strategy & Operations Head on platform decisions, technology selection, and engineering trade‑offs within your domain.


• Design and validate architecture for network security, cloud networking, identity, storage, and observability components across multi‑region Azure and hybrid datacenter environments.


• Produce low‑level design (LLD) documents, architecture decision records (ADRs), and configuration standards for all platforms within your SME domain.


• Evaluate new platform capabilities, vendor features, and emerging technologies; produce formal assessment and recommendation reports for adoption or rejection.


• Define and enforce configuration baselines, hardening standards, and design patterns across your domain — ensuring L1/L2 operations are built on a well‑engineered foundation.

Network Security Platform Engineering

• Architect and implement Palo Alto NGFW deployments — zone design, security policy framework, NAT strategy, Panorama policy hierarchy, and HA/clustering configuration.


• Design and manage Zscaler ZIA and ZPA at an architectural level — tenant configuration, forwarding policy design, PAC file management, SSL inspection architecture, and ZPA application segment design.


• Configure and manage Azure‑native firewall solutions, Web Application Firewall (WAF) policies, Application Gateway rules, and Azure Front Door routing profiles for multi‑region traffic management.


• Manage firewall deployments from Azure Marketplace — lifecycle ownership including initial deployment, policy governance, version management, and decommission planning.


• Define and govern firewall change management processes; review all L2‑submitted rule changes for security posture impact before CAB submission.

Cloud Traffic Management & Networking

• Design and implement multi‑region Azure network topologies — hub‑and‑spoke, Virtual WAN, and peering architectures with ExpressRoute and Site‑to‑Site VPN for hybrid connectivity.


• Architect and manage Azure Load Balancers, Application Gateways, Azure Front Door, and Traffic Manager for high‑availability and geo‑redundant application delivery.


• Design and govern Azure API Management (APIM) deployments — API gateway policies, product configurations, rate limiting, authentication, and developer portal management.


• Implement and manage network traffic management policies — BGP route manipulation, custom UDR configurations, traffic steering, and failover path validation.


• Monitor and analyse sFlow and NetFlow telemetry for network traffic baselining, anomaly detection, and capacity planning across cloud and datacenter network segments.

Identity, Access & Endpoint Security

• Architect and administer Azure AD and ADFS at an enterprise level — hybrid identity design, federation trust configuration, Conditional Access policy frameworks, and Privileged Identity Management.


• Design and manage CyberArk PAM at an architectural level — vault architecture, safe design, master policy governance, CPM/PVWA/PSM component management, and privileged account onboarding strategy.


• Manage Trend Micro EDR (Apex One / XDR) platform — policy framework design, agent deployment strategy, custom detection rules, XDR correlation tuning, and integration with SIEM or observability platforms.


• Define and maintain the privileged access management strategy across cloud and on‑premises environments, ensuring all administrative access flows through governed, auditable pathways.

Observability Engineering

• Architect and own the end‑to‑end observability platform — Prometheus federation design, Grafana enterprise dashboard framework, alerting rule governance, and long‑term metrics retention strategy.


• Deploy, configure, and optimise APM solutions (Dynatrace, AppDynamics, New Relic, Azure Application Insights, or equivalent) — instrumentation strategy, agent rollout, baseline definition, and SLA tracking integration.


• Design and implement sFlow and NetFlow monitoring infrastructure — collector deployment, flow analysis, custom visualisations, and integration with the unified observability platform.


• Build and maintain Azure Monitor and Log Analytics at scale — diagnostic settings governance, KQL query library, workbook templates, and cross‑workspace query architecture for hybrid environments.


• Define observability standards for the managed environment — what must be monitored, how alerts are structured, and how operational health is communicated to stakeholders.


• Architect and manage NetApp ONTAP storage environments — volume layout, aggregate design, QoS policy configuration, SnapMirror replication topology, and storage efficiency settings.


• Manage Azure‑native storage services — storage account configuration, lifecycle policies, Azure NetApp Files, and blob/file/queue/table service governance.


• Lead storage performance investigations — capacity forecasting, throughput bottleneck analysis, and remediation planning for both cloud and on‑premises storage tiers.

Automation, IaC & Knowledge Transfer

• Lead infrastructure‑as‑code adoption within your domain — author Terraform modules, Ansible playbooks, or ARM/Bicep templates for all managed platform components.


• Build automation scripts (PowerShell, Python, Bash) for complex operational tasks that cannot be simplified for L1/L2 — packaging them as governed, documented runbooks.


• Conduct structured knowledge transfer sessions for L2 engineers; develop training materials, lab exercises, and troubleshooting guides to elevate team capability.


• Maintain a domain‑specific knowledge base — detailed configuration guides, architecture diagrams, design decisions, and lessons learned from complex incidents and implementations.
