We are seeking a visionary and hands-on Senior Cloud Architect to lead the transformation of our Middle-Office and Back-Office (BOMO) ecosystems. In this role, you will own the architectural roadmap, design, and cloud infrastructure for our next-generation rates and FX & Derivates trading systems.

You will replace legacy batch processing with a modern, high-throughput, event-driven streaming architecture utilizing AWS Fargate, Amazon EKS (Kubernetes) and Amazon MSK (Apache Kafka). Your mission is to build a highly resilient, scalable data pipeline that seamlessly feeds our Databricks analytics platform while ensuring zero disruption to critical upstream front-office desks and downstream financial systems.

• Define Target-State BOMO Architecture:
  Shape middle- and back-office platform visions to directly support business revenue growth and multi-fold transaction scaling.
• Design Event-Driven Integration (OBS 2.0):
  Architect high-throughput publisher/subscriber patterns using Amazon MSK (Kafka), Amazon EKS, and AWS Fargate.
• Protect Workflow Integrity:
  Guarantee that BOMO system changes maintain strict backward compatibility, preventing any upstream or downstream system disruptions.
• Establish Architectural Governance:
  Create reusable design standards and reference blueprints aligned with broader Enterprise Architecture guardrails.
• Own Cloud Infrastructure & Security:
  Drive 100% automated infrastructure provisioning via Terraform while enforcing a Zero-Trust security and IAM posture.
• Ensure High Availability & Performance:
  Guarantee peak platform reliability and sub-millisecond scalability using active Cloud Watch observability and self-healing systems.

• Experience:
  
  10+ years in IT architecture, with at least 4+ years as a Cloud Architect within Capital Markets, Investment Banking, or Fintech domains.
• Advanced Containerization:
  Production experience architecting, scaling, and managing cloud-native applications on Kubernetes (Amazon EKS) and AWS Fargate / ECS. Knowledge of container lifecycle management, service meshes, and autoscaling paradigms (e.g., KEDA based on Kafka lag) is highly desired.
• Polyglot Engineering Literacy:
  Strong technical background in Java (for enterprise backend frameworks and high-performance Kafka streams) and Python (for data engineering, pipelining, and rapid service deployment). Must be capable of performing deep-dive code reviews.
• Infrastructure as Code Mastery:
  Deep, production-hardened experience writing modular, scalable Terraform configurations to maintain immutable AWS environments.
• Core Messaging Fabric:
  Deep, hands-on production expertise with Apache Kafka (or Amazon MSK), including performance tuning, topic partition strategies, and consumer lag mitigation.
• Integration Patterns:
  Mastery of distributed systems concepts, including event sourcing, CQRS,…
