The platform is built using distributed microservices, runs primarily onVMwarehostedWindows workloads, and is transitioning toward containerized architectures. This role focuses on designing and validating systems that meet strict requirements for availability (99.9%), scalability, performance, and security.

In this role, you will work directly withengineering,infrastructure, andtheCloudOpsteam to designplatformarchitecture,definedeployment patterns, and solvecomplexsystem-levelchallenges.You will activelyparticipateinarchitectural design sessions, review and influence implementation details, and helptroubleshoot and remediate systemic issuesin production environments.TheSeniorPlatformArchitect is expected to deeply understand how the platform is built andoperated, and to apply that knowledge to improve reliability, resilience, andlong-term maintainability of the system.

This role is ideal for an architect who enjoys staying close to technology, contributing to real design decisions, and shaping how distributed systems are built and run in a modernonpremenvironment.

Responsibilities:

• Own theavailability architectureacross compute, network, storage, data, and app tiers to exceed99.9%service availability

• Designfault domains(host, rack, cluster, site) and enforce placement strategies to ensure resilience and predictable failure behaviorandblast radiuslimits

• Eliminatesingle points of failureacross compute, storage, networking, ingress, identity, secrets, and CI/CD pipelines.

• Designgraceful degradation strategiesat the infrastructure leveltomaintaincore functionality during overload or partial failure

• Defineperformance budgets, SLOs, and capacity headroomfor peak traffic and failure scenarios

• DefineSLOs, SLIsand error budgetsand ensure they inform deployment, scaling, and incident response

• DriveinfrastructureascodeandGitOpspractices to ensure consistent, repeatable environments
