The Main Responsibilities
Platform Architecture & Engineering
Design and implement MSSP-grade security platform architectures for multi-customer SOC service delivery.
Engineer unified SecOps capabilities across SIEM, XDR, SOAR, EDR, NDR, cloud security, identity security, threat intelligence, ITSM, vulnerability, and exposure management platforms.
Develop reference architectures, integration standards, data flow diagrams, onboarding patterns, and engineering guardrails.
SIEM, Security Data Pipelines & Telemetry
Build and maintain reliable telemetry ingestion using agents, collectors, syslog, CEF/LEEF, APIs, event hubs, forwarders, cloud connectors, custom connectors, OpenTelemetry where applicable.
Develop parsing, normalization, schema mapping, enrichment, routing, filtering, retention, archival, and data quality controls.
Prioritize critical security telemetry across endpoint, identity, cloud, SaaS, email, firewall, proxy, VPN, DNS, server, application, and database sources.
Monitor ingestion health, data volume, parser quality, delayed or missing data, connector failures, duplication, query performance, and storage/licensing usage.
SOAR, Automation & AI-Assisted SecOps
Design and implement SOAR playbooks for enrichment, triage, escalation, evidence collection, notification, reporting, and case management.
Integrate security platforms using REST APIs, webhooks, scripts, connectors, service principals, certificates, managed identities, and secure secrets handling.
Automate repeatable SOC workflows such as phishing triage, suspicious sign-in response, IOC enrichment, endpoint containment support, case creation, and SLA tracking.
Apply human-in-the-loop controls for high-impact response actions
Detection Engineering Enablement
Work with SOC analysts, threat hunters, and detection engineers to deploy, validate, tune, and maintain detection content across SIEM, XDR, EDR, cloud, identity, and network platforms.
Support MITRE ATT&CK-aligned detection coverage, telemetry gap analysis, threat-informed defence, and purple-team validation.
Enable Detection-as-Code practices, including version control, peer review, testing, deployment, rollback, and reusable detection content libraries.
Platform Lifecycle, Patching & Upgrades
Own lifecycle management for SOC platforms, endpoint agents, cloud agents, collectors, forwarders, connectors, integrations, certificates, API credentials, and supporting infrastructure.
Plan and execute agent patching, collector upgrades, connector updates, integration maintenance, and platform version upgrades across SIEM, XDR, SOAR, EDR, NDR, CNAPP, CSPM, vulnerability, and related security platforms.
Perform pre-upgrade assessment, compatibility checks, dependency mapping, change preparation, test planning, rollback planning, maintenance coordination, and stakeholder communication.
Validate post-upgrade functionality for log ingestion, alert generation, dashboards, playbooks, APIs, ticketing workflows, RBAC, etc
Customer Onboarding & Service Transition
Lead technical onboarding for new MSSP customers from discovery and design through integration, testing, acceptance, and SOC handover.
Create onboarding plans, data flow diagrams, collector designs, integration checklists, validation test cases, runbooks, reporting requirements, and acceptance criteria.
Work with customer IT, network, cloud, endpoint, identity, application, compliance, and vendor teams to enable required telemetry and controlled response workflows.
