Principal Platform Architect

Principal Platform Architect

• Location: Toronto, Ontario , Canada - Remote
• Long Term Contract
• Department: Cloud Infrastructure & Platform Engineering

Job Purpose

As a Principal Platform Architect , you will define the architectural blueprint for our next-generation, high-performance cloud platforms. You will bridge the gap between traditional telecom infrastructure and modern cloud-native environments, designing highly resilient distributed systems that power global 5G network functions and enterprise cloud services.

Key Responsibilities

• Architectural Leadership: Define the multi-year technical roadmap for cloud-native platforms, driving the transition from legacy architectures to modern distributed systems.
• Platform Design: Architect large-scale, high-throughput containerized environments utilizing Kubernetes to run critical cloud-native functions directly on bare-metal and hybrid cloud infrastructures.
• Security & Identity Governance: Design robust identity management, Zero Trust frameworks, and end-to-end security architectures to secure highly distributed cloud environments.
• Observability & Reliability: Implement comprehensive observability strategies (metrics, logs, traces) to ensure 99.999% uptime, deep system visibility, and automated fault resolution.
• Technical Mentorship: Act as a principal subject matter expert, guiding engineering teams through complex design reviews, mentoring senior engineers, and collaborating with global R&D centers.

Required Qualifications

• Experience: 10+ years of software engineering experience, with at least 4+ years acting as a Principal or Enterprise Architect for massive-scale platforms.
• Cloud-Native & Containers: Deep, production-proven expertise in Kubernetes, container runtimes, and the broader CNCF (Cloud Native Computing Foundation) ecosystem.
• Distributed Systems: Mastery in designing distributed, fault-tolerant, and horizontally scalable systems with an understanding of consensus protocols, data replication, and low-latency networking.
• Identity & Security: Advanced knowledge of modern security standards (OAuth2, OIDC, SAML, SPIFFE/SPIRE, and Role-Based Access Control).
• Observability Stacks: Hands-on architectural experience with modern observability tooling (OpenTelemetry, Prometheus, Grafana, Jaeger, etc.).

Preferred Qualifications

• Experience working within telecommunications cloud standards (e.g., Cloud Native Network Functions - CNFs).
• Active participation or contributions to open-source CNCF projects.
• Familiarity with major hyperscaler environments (AWS, Google Cloud, Azure).
