Position Summary:
We are seeking a Senior Technical Architect to own and evolve the architecture of Trend Micro’s distributed secure network access platform. In this role, you will define the architectural vision for a hybrid system spanning customer-deployed components and cloud-hosted (SaaS) services, ensuring scalability, reliability, performance, and long-term maintainability. You will guide system-wide design decisions, establish clear architectural guardrails, and enable multiple engineering teams to deliver independently and efficiently. This is a highly collaborative role requiring deep distributed systems and networking expertise, strong technical judgment, and the ability to translate complex tradeoffs into clear direction across engineering, product, and security stakeholders.

Responsibilities:

• Own and evolve the end-to-end architecture of a distributed network access platform spanning on-prem agents and connectors, and cloud-hosted relay and management (SaaS) components.

• Define architectural direction and guardrails to ensure scalability, high availability, regional failover, performance, and long-term evolvability.

• Design architectures that enable a small number of semi-autonomous teams to deliver independently, without excessive coordination overhead.

• Make and guide system-wide architectural decisions, including protocol selection (e.g., transport, multiplexing, RPC), based on performance, reliability, and maintainability tradeoffs.

• Establish strategies for backward compatibility, upgrades, and incremental system evolution.

• Produce and maintain architecture artifacts such as design documents, diagrams, tradeoff analyses, and reference implementations.

• Review and approve designs across multiple development teams, providing clear, actionable feedback.

• Mentor and coach engineers on distributed systems design, architectural tradeoffs, and pragmatic decision-making.

• Collaborate with product management, customers, field engineering, and security researchers to shape designs and propose integration approaches for secure access to internal and internet-facing resources.

• Occasionally implement prototypes or targeted production code to validate designs or unblock teams.

Required Qualifications:

• Significant experience designing and evolving large-scale distributed systems with ownership of architectural decisions.

• Strong understanding of networking fundamentals and L4/L7 behavior, including protocol tradeoffs relevant to hybrid on-prem and cloud systems.

• Experience selecting and applying existing protocols and technologies in production environments.

• Proven ability to reason about scalability, latency, performance budgets, consistency, and failure modes.

• Experience designing architectures that enable multiple semi-autonomous teams to deliver independently.

• Experience designing and operating cloud-hosted, as-a-service platforms, alongside on-prem components deployed in customer environments.

• Familiarity with cloud environments, operating primarily in Azure with supporting components in other providers.

• Familiarity with AI tools across the software development lifecycle, and the ability to collaborate effectively alongside such tools to enhance productivity and innovation.

• Strong written and verbal communication skills, including explaining designs and tradeoffs to technical and non-technical stakeholders.

• Hands-on software development experience, with the ability to contribute code when appropriate.

Nice to Have:

• Experience building network-centric access products such as gateways, proxies, or secure connectivity platforms.

• Experience working on systems that broker or mediate access between users, devices, and protected resources.

• Experience operating and evolving long-lived systems across multiple versions and deployment models.

• General familiarity with security concepts relevant to networked, distributed systems.

What Success Looks Like:

• New features integrate cleanly into the architecture without large-scale refactoring.

• Teams deliver quickly and independently within clear architectural boundaries.

• The system balances performance, reliability, and developer productivity over time.
