A Brief Overview

As a Principal Security Architect focused on the Product and Application Security domain, this role serves in two complementary capacities. First, it is responsible for defining and embedding security architecture, standards, and practices into TriNet’s Value Creation Process, ensuring that security is integrated by design across the product and application lifecycle. Second, the role acts as a consultative reviewer and advisor for individual solutions, providing architectural guidance, risk insight, and design feedback as they progress through the Value Creation Process. Together, these responsibilities ensure that security is both scalable as a process and applied thoughtfully to individual products.

Although you will collaborate with other security architects who have deep expertise in adjacent domains, a strong understanding of all security architecture domains is important to effectively embed security into the Value Creation Process and provide informed guidance on individual product and application designs. These domains include Identity and Access Management, Cloud Security, Endpoint Security, Security Operations, and Governance, Risk, and Compliance.

The successful candidate will be a trusted advisor to engineering and product leaders, combining deep technical expertise with strong communication skills. This role is both strategic and hands‑on, shaping how security is embedded into the Value Creation Process while also guiding architecture decisions and risk tradeoffs for individual products and applications as they are designed and delivered at scale.
