Cyber Security Practice Principal Jobs (NOW HIRING)

Summary:

The Principal Architect, Security Architecture is a senior individual-contributor and enterprise technical leadership role responsible for defining, governing, and advancing cybersecurity architecture across the enterprise in collaboration with other Principal Architects, Cybersecurity Architects, & Cybersecurity and domain engineering teams.

The Principal Architect translates business strategy, technology direction, cyber risk, regulatory obligations, and emerging threats into practical security architectures, principles, patterns, standards, and technology decisions that enable the business while measurably reducing risk.

This role operates beyond individual cybersecurity products or domains. The Principal Architect - Cybersecurity works horizontally across the functional technology domains and the related security practices for Cloud, Infrastructure, Endpoint, Network, Storage; while also collaborating and representing core cybersecurity practices such as Identity & Access Management, Application Security, Data Security, AI Security, Cyber Defense, SaaS Security, OT/IoT, and emerging technologies, ensuring that security capabilities function as an integrated enterprise architecture rather than independent controls.

The successful candidate must combine the depth of a senior security technologist with the influence, judgment, and communication capabilities of an enterprise architect. This position is expected to challenge legacy assumptions, resolve difficult cross-domain architecture decisions, simplify security complexity, and establish clear technical direction where ownership or requirements are ambiguous.

This is not primarily a documentation, compliance, or architecture-review role. The Principal Architect - Cybersecurity is expected to shape technology and cybersecurity platform strategy and materially influence what the enterprise builds, buys, integrates, modernizes, and retires.

Will Lead or Collaborate to Deliver Application & API Security Architecture

• Integrate cybersecurity architecture into application modernization and secure software development practices.

• Establish reusable security patterns for APIs, microservices, authentication, authorization, secrets, service-to-service communications, software supply chains, and cloud-native applications.

• Partner with AppSec and development organizations to move security requirements earlier into architecture and engineering.

• Promote security capabilities that can be consumed through standardized platforms, APIs, pipelines, and reusable engineering components rather than manual security reviews.

Will Lead or Collaborate to Deliver Identity & Zero Trust

• Partner with IAM architecture and engineering to establish enterprise identity security patterns.

• Ensure workforce, privileged, machine, service, workload, API, and customer identities are incorporated into enterprise security architecture.

• Advance policy-based and identity-aware access models that reduce dependence on network location as the primary trust mechanism.

• Integrate identity, device posture, workload identity, data sensitivity, threat signals, and contextual risk into access-control architecture.

Will Lead or Collaborate to Deliver Cyber Defense & Resilience

• Ensure architecture decisions incorporate detection, telemetry, investigation, containment, recovery, and operational resilience requirements.
