About the role

We are looking for a System Architect for Observability & Monitoring Platforms with 15+ years of experience who will own and drive the end-to-end architecture of a large-scale infrastructure monitoring and cloud orchestration platform. This role focuses on system architecture, technical strategy, and long-term platform evolution, enabling the platform to support metrics, logs, distributed tracing, and application performance monitoring at scale.

This role combines strategic architectural ownership with hands-on validation through design reviews, code reviews, and targeted proof-of-concepts (POCs).

What you will be doing (Role Accountabilities)

Architecture Ownership & Vision

Own the overall system architecture of the observability platform across ingestion, processing, storage, and query layers.

Work closely with Enterprise Architect to align system architecture with long-term architectural vision and technical roadmap aligned with business and platform goals.

Design and review high-level system designs, data flows, integration patterns, and core technology choices.

Act as the technical authority for complex architectural decisions, trade-offs, and design reviews.

Platform & Domain Leadership

Architect systems for infrastructure monitoring, metrics, logs, and distributed tracing at scale.

Guide the evolution from infrastructure monitoring to a full observability platform including APM.

Define architectural patterns for high-throughput telemetry ingestion, real-time processing, and query-at-scale.

Ensure architectural consistency for multi-tenant, cloud-native distributed platforms.

Standards, Governance & Enablement

Establish and evolve architecture standards, design principles, and best practices across teams.

Identify architectural risks and proactively drive mitigation strategies.

Enable teams through reference architectures, design frameworks, and technical guidance.

Support modernization initiatives including scalability, performance optimization, resilience, and cost efficiency.

Hands-On Architectural Validation

Perform code reviews of critical and performance-sensitive components.

Build and guide proof-of-concepts (POCs)



to validate architectural decisions and de-risk new technologies.

Develop reference implementations to demonstrate architectural intent.

Collaborate closely with senior engineers to troubleshoot complex system-level issues

Delivery Collaboration & Execution Enablement

Work closely with Software Engineering Managers to align architectural decisions with delivery and release plans.

Assist in breaking down large architectural initiatives into phased, incremental deliverables.

Identify architectural and technical risks early and proactively surface them to influence release planning.

Support release readiness by validating that architecture, scalability, and nonfunctional requirements are addressed ahead of key milestones.
