Strong grounding in security fundamentals: IAM, application security, data protection, credential management, endpoint and cloud security
Deep experience designing and delivering RESTful APIs and service-based architectures
Practical expertise with containers, orchestration, and infrastructure abstractions (Docker, Kubernetes, API gateways, service meshes)
Strong programming skills in Python, Java, C++, or similar (polyglot experience is a plus)
Hands-on experience with CI/CD pipelines (e.g., GitHub Actions) and modern DevSecOps practices
Cloud-native delivery experience on AWS, Azure, and/or GCP
Awareness of threat modeling, security architecture reviews, and risk analysis
Experience driving technical alignment across multiple engineering teams or organizations, including executive-level communication and architectural governance

Nice To Haves

Familiarity with security data analysis, ML, or AI-enhanced security workflows is a bonus

Responsibilities

Design and implement core security platform services that expose reliable, well-instrumented interfaces that are consumed by customers of the Security Platform
Translate security and product requirements into architecture and code—from proof of concept to hardened, production-ready services
Own the technical strategy and multi-year roadmap for the Security OS area; break it into credible incremental milestones that can be delegated to domain leads for execution
Serve as the technical go-to leader for architecture, platform design, and escalations within the area; document rationale and ensure teams have clear implementation paths
Partner with engineering managers, product leaders, and security executives as peers to align technical direction with business outcomes; represent the area in cross-organizational architecture forums
Provide technical oversight across the delivery lifecycle—architecture, quality standards, deployment practices, and operational readiness—while delegating execution to engineering teams
Design automation-first workflows, integrating security services and telemetry from diverse tools and data sources
Design and build integrations, plugins, and hooks across the security ecosystem (IAM, app sec, endpoints, cloud, data protection)
Evaluate and adopt emerging technologies, including AI-driven and open-source security tooling, where they add measurable value
Define and evolve service APIs, ensuring they are scalable, secure, and aligned with platform capabilities
Ensure platform reliability by designing for SLA/SLO compliance, observability, and fault tolerance
Proactively identify technical risks and bottlenecks, driving resolution before they impact delivery or reliability
