Secondary Skills:  Kafka,  Git/version control, Terraform, CI/CD pipelines, Unit testing frameworks (xUnit, Jest)

Nice to Have: Azure cloud platform, Redis, Microservices architecture, MFE Architecture

AI & Tooling: Experience evaluating and incorporating AI-assisted development, testing, and observability tools into architectural designs and standards, including guidance on patterns and risks.

What You'll Do

• Define and document target architectures, domain boundaries, and integration patterns for the platform, with a focus on modularity, testability, and resilience.

• Partner with P5 Staff Engineers, P6 Principal/Enterprise Architects, and product leadership to translate business and product strategy into actionable architectural roadmaps.

• Create and maintain architectural artifacts such as context diagrams, sequence diagrams, data models, and API/interface contracts.

• Evaluate current-state systems and propose pragmatic migration paths to the target architecture, including strangler patterns, domain carve-outs, and phased delivery approaches.

• Collaborate with engineering teams to ensure designs are understood, feasible, and implemented as intended, providing hands-on guidance and design reviews as needed.

• Define non-functional requirements (security, performance, availability, scalability, observability) and ensure they are incorporated into designs, backlogs, and acceptance criteria.

• Work closely with Quality Engineering and DevOps to ensure architectures support automated testing, CI/CD quality gates, and robust observability and incident response.

• Assess and recommend technologies, frameworks, and platforms (including AI-assisted tools) that align with enterprise standards and the needs of the platform.
