Job description

Location: Phoenix, AZ

Job Type: Contract Position

Important:

A generic Java Architect with banking experience may not be sufficient. The key differentiator is deep commercial banking and capital markets domain knowledge combined with hands-on Java architecture.

About the Role:

We are seeking a hands-on Principal Engineer to lead the architectural direction and engineering strategy for next-generation Commercial Banking platforms. The role will focus on building enterprise-scale, data-driven and AI-enabled applications supporting Capital Markets, Corporate Banking, Global Markets, and Commercial Lending.

The Principal Engineer will drive end-to-end platform architecture, establish engineering standards, and guide the development of resilient, cloud-native services integrating modern front-end applications, microservices, enterprise data platforms, operational databases, and core banking and trading systems.

Key Responsibilities:

1. Architecture Strategy & Platform Engineering

• Define and govern end-to-end platform architecture for enterprise Commercial Banking applications, ensuring high availability, scalability, sub-second responsiveness, resilience, and data governance.
• Drive platform modernization from data extraction and operational storage solutions toward enterprise data-serving layers using Snowflake, interactive query warehouses, semantic layers, and event-driven streaming with Kafka.
• Design scalable microservices using Java/Spring Boot, front-end integrations using ReactJS, and NoSQL operational stores using MongoDB.
• Establish architecture standards, reusable engineering patterns, and target-state technology roadmaps.

2. Banking Domain Integration & System Alignment

• Design integrations connecting CRM platforms such as Salesforce and DealCloud with enterprise data platforms such as Snowflake.
• Enable unified Client 360 views, including company, entity, and instrument relationships, wallet share analytics, relationship intelligence, and deal pipeline visibility.
• Lead architecture integration with capital markets, trading, and post-trade platforms, including Calypso and Wallstreet FX/ION FX.
• Support integration across derivatives, foreign exchange, collateral management, settlement, and regulatory reporting workflows.
• Drive technology solutions supporting commercial lending, asset-based lending, bilateral credit facilities, loan syndications, underwriting, and borrower debt maturity monitoring.
• Ensure alignment with regulatory reporting platforms and frameworks, including Cappitech, DTCC/GTR, CFTC/Dodd-Frank, and EMIR.

3. AI & Governed Agentic Innovation

• Lead the technical architecture for AI-generated dynamic screens, widgets, and banker-facing experiences using enterprise LLM platforms such as AWS Bedrock.
• Design and integrate Model Context Protocol (MCP) tools and agentic AI capabilities into enterprise applications.
• Establish governance and architectural guardrails using Maker-Checker review models.
• Separate agentic exploration from certified runtime execution through parameterized APIs, controlled schemas, auditable data contracts, and deterministic workflows.

4. Technical Leadership & Governance

• Champion engineering excellence, secure SDLC, site reliability, automated CI/CD, and infrastructure-as-code practices.
• Drive AWS modernization initiatives, including migration from EC2-based workloads toward containerized environments using EKS.
• Partner with enterprise architecture, information security, IT resilience, and model risk governance teams to ensure compliance with enterprise banking standards.
• Mentor senior engineers, technical leads, and engineering teams while providing technical direction across multiple development pods.

Required Qualifications

• 10+ years of progressive experience in software engineering, systems architecture, and development of large-scale, mission-critical distributed enterprise applications.
• Financial services or banking domain experience with in-depth knowledge across the following areas:
• Capital Markets: Debt Capital Markets (DCM), Equity Capital Markets (ECM), M&A deal structures, loan syndications, and valuation modeling.
• Global Markets: OTC derivatives, interest rate derivatives, FX Spot, Forwards, NDFs, Swaps, collateral management, and regulatory frameworks.
• Corporate Banking: Client relationship hierarchies, Client 360, parent/subsidiary/instrument structures, coverage workflows, and wallet share attribution.
• Commercial Lending: Commercial credit underwriting, asset-based lending (ABL), bilateral debt structuring, debt maturity monitoring, and credit risk screening.
• Strong hands-on experience designing microservices architectures and distributed systems.
• Experience with event-driven architecture and messaging technologies such as Kafka or MQ.
• Proven experience building and scaling cloud-native applications on AWS.
• Strong experience with modern data warehouse platforms, preferably Snowflake.
• Experience leading architecture decisions, technical governance, and enterprise application integration.
• Bachelor's or Master's degree in Computer Science, Computer Engineering, Information Systems, or equivalent practical experience.

Preferred Qualifications & Technical Skills

• Java, Spring Boot, REST/GraphQL APIs, enterprise integration patterns, and secure API gateways.

Frontend & UX Architecture

• ReactJS, modern front-end architecture, state management, and component libraries.

Database & Storage

• MongoDB, including sharding, indexing, operational document stores, and caching.
• Relational databases such as PostgreSQL and Oracle.

Capital Markets & Banking Platforms

• Calypso, Wallstreet FX/ION FX, DealCloud, Salesforce Financial Services Cloud (FSC), or similar banking and trading platforms.

Market Data & External Protocols

• Bloomberg BPIPE/PrivateLink, Refinitiv, Cappitech, DTCC, SWIFT, and NTS.
• AWS Bedrock, LLM orchestration frameworks, LangChain, LlamaIndex, Model Context Protocol (MCP), and enterprise agentic AI integration.

Infrastructure & Security

• AWS EKS, Kubernetes, Docker, Terraform, IAM, mutual TLS, and zero-trust security architectures.
