What We Do

Our Security Operations Center (SOC) protects the enterprise by detecting, investigating, and responding to cybersecurity threats.

As a member of our Threat Detection Engineering team operating within our SOC, you will build governed agent capabilities to support data onboarding, detection engineering, threat hunting, investigation, response, automation, and platform operations. Our goal is to expand threat visibility, accelerate security outcomes, reduce repetitive work, and improve operational consistency and resilience without compromising sound security judgment, human accountability, or control.

The Principal Engineer provides hands-on technical leadership to turn this strategy into secure, reliable, and supportable production capabilities across the SOC.

• We are open to remote candidates for this role

What You’ll Do

• Lead the architecture and hands-on implementation of Agentic Security Operations capabilities across the SOC.
• Define and evolve the reference architecture for governed data services, agent capabilities, workload routing, execution environments, and deterministic orchestration.
• Build reusable capabilities that translate operational intent into tested, reviewable, and auditable security outcomes.
• Establish engineering standards for creating, testing, registering, approving, releasing, monitoring, and retiring agents and their capabilities.
• Advance detection-as-code practices, including versioning, simulation, deployment, tuning, migration, and rollback.
• Build governed knowledge and context services that provide authoritative documentation, policies, operational history, citations, freshness information, and permission-aware retrieval.
• Design workload identity, least-privilege access, short-lived authorization, spend controls, approval gates, audit trails, rollback, and emergency shutdown mechanisms.
• Define autonomy levels that determine which activities may execute automatically, require human approval, or remain analyst led.
• Establish agent evaluation and observability through historical replay, synthetic scenarios, expected-versus-actual comparisons, policy tests, traces, outcome verification, and regression testing.
• Measure quality, security, reliability, latency, cost, analyst acceptance, and operational impact.
• Engineer reliable integrations across search, case management, workflow, communications, and response systems, including retries, idempotency, partial failures, and reconciliation.
• Ensure consequential response actions remain deterministic, attributable, reversible, and subject to appropriate human oversight.
• Design production reliability, continuity, recovery, and support models for agent capabilities and security data services.
• Lead proofs of concept and architecture evaluations using measurable criteria for security, fidelity, scale, reliability, portability, operating effort, and economic value.
• Collaborate with enterprise architecture, infrastructure, data, risk, privacy, legal, and compliance teams.
• Mentor engineers, establish technical standards, review designs, and influence Threat Detection Engineering strategy.
• Present complex technical decisions, risks, tradeoffs, and investment recommendations clearly to engineering and executive stakeholders.
• Partner across Threat Detection and Response groups, including engineering, threat hunting, security analysis, investigation, and incident response stakeholders on initiatives and to translate operational feedback into improvements within our agentic harness, evaluations, safeguards, workflows, and other platforms.
