Senior Security Architect — Managed Security Services

About the Role

Bespin Global US delivers managed security services to organizations that need enterprise-grade detection and response without building it themselves — endpoint detection and response (EDR), 24x7 SOC services, SIEM and SOAR management, security assessments, and cloud security posture management (CSPM).

This role sits at the center of that practice with a dual mandate. You will engineer the platform our services run on — the SIEM/SOAR pipelines, EDR deployments, detection content, and integrations that our analysts depend on — and you will be the senior technical voice with customers, scoping new engagements, leading onboarding, and advising security leaders on how to mature their programs.

This is not a shift-based SOC seat. You are the person who decides how the service works, then makes it work for each customer.

What You'll Do

Platform & Detection Engineering

• Own the architecture and build-out of the multi-tenant SIEM and SOAR environments underpinning our managed detection services — primarily Google SecOps, with Elastic and Coralogix supporting customer-specific and log analytics use cases
• Design and deploy EDR tooling across customer estates using SentinelOne and CrowdStrike; standardize policies, exclusions, and response actions
• Build and maintain detection content — correlation rules, analytics, and use cases mapped to MITRE ATT&CK — and tune continuously to reduce false positives
• Develop SOAR playbooks that automate triage, enrichment, containment, and notification workflows
• Engineer log ingestion and normalization pipelines with BindPlane across cloud, endpoint, identity, and network sources; manage data volume, routing, and ingest cost
• Stand up and maintain Wiz for cloud security posture management across AWS, Google Cloud, and Azure; define policy baselines, risk prioritization, and remediation guidance
• Design and maintain secure connectivity into customer environments using Tailscale, keeping collector and management access least-privilege and auditable
• Automate deployment and configuration through infrastructure-as-code and scripting rather than manual, per-customer work
• Evaluate new security tooling and make build-vs-buy recommendations for the practice

Customer-Facing Delivery & Advisory

• Lead technical discovery and scoping for prospective customers; translate their environment and risk profile into a service design
• Own the technical execution of customer onboarding — from log source integration through first tuned detections and validated response workflows
• Serve as the escalation point and trusted advisor for the customer's security stakeholders after go-live
• Conduct security assessments and cloud posture reviews; present findings and prioritized remediation roadmaps to technical and executive audiences
• Partner with sales on solution design, technical proposals, and statements of work
• Produce reference architectures, runbooks, and documentation that let the SOC and delivery teams operate what you build

The Stack You'll Work With

We are not tool-agnostic for the sake of it — we run a deliberate stack and expect you to help shape where it goes next.

What You Bring

Required

• 7+ years in security engineering, security operations, or security consulting, including hands-on ownership of a SIEM platform
• Deep, hands-on experience with at least one modern SIEM — Google SecOps (Chronicle), Elastic, or Coralogix strongly preferred — including data onboarding, parsing and normalization, and detection authoring
• Hands-on experience deploying and operating EDR/XDR platforms; SentinelOne and CrowdStrike specifically preferred
• Experience with a CSPM/CNAPP platform such as Wiz, including policy baselines and risk-based remediation workflows
• Working knowledge of SOAR platforms and automation of security workflows
• Strong cloud security fundamentals across AWS, Google Cloud, or Azure — native security services, identity, and posture management — with the ability to work in at least two
• Scripting and automation skills (Python, PowerShell, or equivalent) and comfort with infrastructure-as-code
• Demonstrated ability to communicate directly with customers — running technical workshops, presenting findings, and handling escalations with credibility
• Working familiarity with common frameworks and standards (MITRE ATT&CK, NIST CSF, CIS Benchmarks, SOC 2)

Preferred

• Prior experience in an MSSP, MSP, or consulting environment supporting multiple customers concurrently
• Incident response experience, including leading investigations end to end
• Multi-cloud breadth across AWS, Google Cloud, and Azure
• Experience with telemetry pipeline tooling (BindPlane, OpenTelemetry, Cribl, or similar) and log cost optimization
• Familiarity with zero-trust or mesh networking tools such as Tailscale for customer environment access
• Certifications such as GCIA, GCIH, GCDA, CISSP, OSCP, or cloud security specialty credentials
• Experience with detection-as-code practices and CI/CD for security content
• Exposure to pre-sales solutioning and SOW development

What Success Looks Like

• First 90 days: fluent in our service stack and delivery model; leading onboarding for at least one new customer; first detection content improvements shipped
• First 6 months: owning the technical design of the SIEM/SOAR platform; measurable reduction in false-positive volume; recognized as the escalation point across the delivery team
• First year: onboarding is faster and more repeatable than when you arrived; detection coverage is measurably broader; customers name you as a reason they stay
