Position Overview: 

The Instant Financial Issuance as a Service (IFIaaS) Cloud Service consists of various components, such as web services, application servers, and databases, all hosted in an on-premises environment. We are seeking a Senior Platform Architect who is hands-on and deeply involved in the design and evolution of a modern, on premises SaaS platform. The platform is built using distributed microservices, runs primarily on VMwarehosted Windows 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 with engineering, infrastructure, and the CloudOps team to design platform architecture, define deployment patterns, and solve complex system-level challenges. You will actively participate in architectural design sessions, review and influence implementation details, and help troubleshoot and remediate systemic issues in production environments. The Senior Platform Architect is expected to deeply understand how the platform is built and operated, and to apply that knowledge to improve reliability, resilience, and long-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 modern onprem environment. 

Responsibilities: 

• Own the availability architecture across compute, network, storage, data, and app tiers to exceed 99.9% service availability 

• Design fault domains (host, rack, cluster, site) and enforce placement strategies to ensure resilience and predictable failure behavior and blast radius limits 

• Eliminate single points of failure across compute, storage, networking, ingress, identity, secrets, and CI/CD pipelines. 

• Design graceful degradation strategies at the infrastructure
