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   p latform   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   on prem   environment.

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

• Design   graceful degradation strategies   at the infrastructure level   to   maintain   core functionality during overload or partial failure  

• Define   performance budgets, SLOs, and capacity headroom   for peak traffic and failure scenarios  

• Define   SLOs , SLIs   and error budgets   and ensure they inform deployment, scaling, and incident response  

• Drive   infrastructure as code   and   GitOps   practices to ensure consistent, repeatable environments   

• Define and enable   progressive deployment models   (canary, blue/green, rolling) with automated rollback  

• Build   platform   and CI/CD   capabilities   that directly improve   ( deployment frequency, lead time for changes, change failure rate, mean time to recover MTTR )  

• Embed   security by design , including   zero trust   networking,   mTLS , secrets management, and   least privilege   access  

• Establish   standard observability   for metrics, logs, traces, and health signals across the platform  

• Enable   operational   and incident response   readiness , including runbooks, failure testing, and automated remediation  

• Act as the   technical authority   for platform architecture decisions and   trade offs    

• Partner with engineering teams to   onboard services   and ensure alignment with platform standards  

• Provide reference architectures, patterns, and guidance that improve   developer experience and delivery speed.

Basic   Qualifications:   

• Bachelor’s degree in computer science , Software Engineering, or equivalent   combination of education and experience    

• 8 + years of   related experience   as a   Platform/   Solutions/ System Design Architect,   Software Engineer,   Senior   DevOps   Engineer   or a role in similar capacity  

• Proven experience designing   distributed systems   with an emphasis on   availability, scalability, resilience, and performance  

• Demonstrated   expertise   in   microservices architecture , API design, and   service   to   s ervi ce communication patterns  

• Strong knowledge of   system design principles   including fault tolerance, capacity planning, dependency isolation, and failure handling
