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.

(Not Required but a Plus) 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.

(Not Required but a Plus) 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.
