About the Role

We are hiring a Senior Information Security Engineer to design, build, automate, operate, and continuously improve the security platforms that power modern Managed Security Services Provider (MSSP) Security Operations Centre services.

This is a senior hands-on engineering role for someone who can take end-to-end ownership of platforms across SIEM, XDR, SOAR, security data pipelines, threat intelligence, cloud security, identity protection, exposure management, and SecOps automation.

In one sentence: Own and engineer the end-to-end MSSP security platform ecosystem to deliver scalable, automated, resilient, and measurable 24x7 SOC services.

What You Will Do

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.

· Design for resilience, availability, maintainability, scalability, and secure service operation.

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, and event streaming platforms.

· 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.

· Optimize ingestion cost and retention strategy without reducing required detection and investigation visibility.

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 such as account disablement, endpoint isolation, firewall blocking, and production containment.

· Support AI-assisted SecOps workflows, such as investigation summaries, natural language search, analyst assistance, detection support, and playbook development support, with appropriate governance and validation.

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.

· Support detection formats and query languages such as KQL, SPL, XQL, Sigma, YARA, YARA-L, or similar where applicable.

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, reporting, and customer-specific service outcomes.

· Maintain upgrade roadmaps and documentation to keep platforms secure, stable, supported, scalable, and service-ready.

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.

· Ensure each customer onboarding includes health checks, ownership, alert routing, severity mapping, escalation process, reporting, and operational readiness.

What You Will Bring

· 5+ years of cybersecurity engineering, security platform engineering, SOC engineering, security data engineering, or security infrastructure experience.

· 3+ years of hands-on experience designing, deploying, maintaining, or upgrading SIEM and/or SOAR platforms in an enterprise, MSSP, MDR, SOC, or security consulting environment.

· Hands-on experience with at least one major SIEM platform such as Microsoft Sentinel, Splunk, Cortex XSIAM, Google SecOps,FortiSIEM, QRadar, or equivalent.

· Hands-on experience with at least one SOAR or automation platform such as Cortex XSOAR, FortiSOAR, Splunk SOAR, MicrosoftSentinel automation, Azure Logic Apps, Google SecOps SOAR, or equivalent.

· Experience with agent deployment and patching, collector and forwarder management, connector updates, platform upgrades, change control, rollback planning, and production validation.

· Strong understanding of security telemetry across cloud, SaaS, identity, endpoint, network, application, database, and infrastructure environments.

· Working knowledge of APIs, scripting, automation, secrets handling, service principals, certificates, secure integration design, and production support practices.

· Strong troubleshooting capability across source devices, agents, collectors, network paths, parsers, ingestion pipelines, storage, dashboards, alerts, playbooks, and ticketing integrations.

· Ability to produce clear architecture diagrams, technical documentation, runbooks, onboarding artefacts, and stakeholder-ready explanations.

Preferred Certifications

· Microsoft SC-200, SC-100, AZ-500, or equivalent Microsoft security certifications.

· Splunk Admin / Architect, Palo Alto Cortex XSOAR or XSIAM, Fortinet NSE, Google SecOps, or other platform certifications.

· GIAC certifications such as GCIA, GCIH, GCFA,GDAT, GCTI, or equivalent practitioner certifications.

· CISSP, CCSP, AWS Security Specialty, or cloud/security architecture certifications.

· Training or practical experience in MITREATT&CK, detection engineering, threat hunting, purple teaming, cloud security, platform engineering, or DevSecOps.

What Success Looks Like

· Security platforms, agents, collectors, connectors, and integrations remain healthy, supported, and operationally reliable.

· Critical telemetry is consistently onboarded, validated, enriched, monitored, and available for detection and investigation.

· Platform upgrades and patching are completed safely with clear validation, rollback planning, and minimal service disruption.

· SOAR and AI-assisted workflows reduce manual effort, improve consistency, and support faster triage and response.

· Detection content is tested, tuned, version-controlled, operationally useful, and aligned to relevant threat behaviors.

· New customer environments are transitioned into SOC operations with validated telemetry, documented architecture, and agreed runbooks.

· Platform health, detection coverage, automation coverage, cost, and service improvement metrics are measurable and reportable.

Why Join This Role

· Work on the engineering foundation of modern MSSP SOC services rather than only operating individual tools.

· Shape scalable platforms across SIEM, XDR, SOAR, cloud, identity, automation, AI-assisted SecOps, and security data engineering.

· Partner with SOC analysts, threat hunters, cloud teams, customers, and vendors to build practical, measurable security outcomes.

· Drive high-impact improvements in automation, telemetry reliability, detection quality, platform resilience, and customer onboarding.
