What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a Staff Professional Services Architect you will govern the technical quality of AI SIEM deployments in EMEA and APJ. You will advise LevelBlue delivery architects on ingest architecture, integrations, parser validation, deployment prerequisites, and difficult implementations. This role keeps SentinelOne's technical standards consistent across a diverse regional footprint while enabling LevelBlue to lead implementation execution and resolve issues efficiently.

What Will You Do?

Primary responsibilities include:

• Create and adapt AI SIEM reference architectures and design-review checklists for EMEA and APJ enterprise deployments.
• Review LevelBlue solution designs involving data sources, ingestion, collectors, integrations, access requirements, and security use cases.
• Validate parser quality, data normalization, ingest assumptions, and readiness of production data pipelines.
• Support technically complex implementation escalations, identify root causes, and coordinate product-level resolution where required.
• Ensure POV evidence, data sizing, and technical exit criteria are transferred accurately into deployment requirements.
• Coach LevelBlue architects on approved architecture patterns, release changes, and recurring integration problems.
• Advise on regional customer constraints, including data locality, security governance, and multi-environment complexity when relevant.
• Engage Product, Engineering, and Support to address systemic delivery issues and remove avoidable technical friction.
• Publish reusable design guidance, evidence-based technical review findings, and lessons learned for the regional partner teams.

What Skills and Knowledge Should You Bring?

Ideal candidates will have:

• 5+ years in enterprise SIEM engineering, security data architecture, professional-services consulting, or technically complex platform delivery.
• Hands-on knowledge of ingestion architecture, APIs, parser validation, log normalization, and SIEM data quality.
• Strong understanding of SOC requirements, data-source onboarding, and production security operations.
• Experience designing solutions for global or multi-region enterprise environments.
• Ability to analyze difficult implementation failures and guide multiple technical organizations to resolution.
• Strong written technical guidance, customer communication, and partner enablement.
• Ability to establish regional architectural consistency while accommodating legitimate customer constraints.
