Citi - Remote - Application Solution Architect - Contractor

 

Role Description

Application Solution Architect – APIs & Real‑Time Streaming (Financial Services)

  • Shape and lead target-state architecture for secure, low-latency API and Kafka-based streaming platforms across client engagements in payments, trading, risk, and fraud — working within regulated financial environments.
  • Design and advise on real-time data pipeline architecture using Kafka, Spark, and microservices across hybrid on-prem and cloud infrastructures (AWS/Azure/GCP), tailored to each client's technology landscape.
  • Define client-facing architecture guardrails for performance, resilience, scalability, and high availability — spanning throughput, latency, failover, and operational readiness — and drive adoption through governance frameworks.
  • Embed security and compliance by design across API gateways, OAuth2/mTLS, encryption, and observability, aligned to financial-grade API standards and client regulatory obligations.
  • Lead enterprise modernization engagements — guiding clients from legacy integration patterns to event-driven and API-first architectures — influencing business, engineering, risk, and security stakeholders up to the executive level.
  • Architect and deliver AI-enabled platform capabilities — including agentic workflows, LLM integration, and intelligent data pipelines — helping financial services clients operationalize AI within governed, production-grade environments.
  • Design graph-based architecture solutions using platforms such as Neo4j to model complex financial relationships — entity resolution, risk lineage, fraud network detection — and integrate graph layers into broader data and metadata ecosystems.

 

Technical Skills 

• 6+ years in enterprise or solution architecture, with at least 3 years in financial services — across banking, payments, capital markets, or lending.

• Consulting or advisory background — comfortable owning architectural outcomes in complex, multi-stakeholder environments.

• Deep expertise in Apache Kafka, event-driven architecture, and real-time streaming platforms at scale.

• Strong hands-on background in RESTful and async API design, API gateway products, and microservices architecture.

• Solid grasp of financial services regulatory requirements (PCI-DSS, SOX, DORA, Basel) and how they shape platform design.

• Experience with AWS and hybrid cloud architectures in regulated environments.
