A leading financial technology organization is seeking a Senior Solution Architect specializing in designing and delivering enterprise-scale solutions within the financial services industry. The ideal candidate will have a strong application development background, deep expertise in banking systems, and a proven track record architecting massively scalable, high-availability, and disaster-resilient enterprise applications.

Key Responsibilities
Solution Architecture & Design

• Lead end-to-end solution architecture for mission-critical financial systems, focusing on Real-Time Gross Settlement (RTGS), Customer Service/Operations (CSU), and Anti-Money Laundering (AML). You will be responsible for the "zero-failure" infrastructure that moves and protects high-value assets.

  • Payments & Settlement: Architect high-value payment flows using ISO 20022 standards and manage the migration from legacy formats

  • Compliance & Risk: Integrate real-time AML/KYC screening and fraud detection engines into transaction workflows without increasing latency.

  • Operational Integrity: Design CSU frameworks that support immutable audit trails, data lineage, and complex lifecycle management for financial products.

  • Resilience: Define strategies for Zero Data Loss (RPO=0) and sub-minute recovery (RTO) using multi-region, active-active cloud architectures.

  • Data Consistency: Ensure strong ACID compliance across distributed systems to maintain ledger integrity.

• Design architectures that meet massive scalability, high availability (HA), and disaster recovery (DR) requirements.

• Develop high-level and detailed architecture designs aligned with enterprise standards, regulatory compliance, and security best practices.

• Evaluate technology options and recommend architectural patterns, integration strategies, and platform selections.

• Drive cloud-native architecture adoption (AWS, Azure, GCP), focusing on elastic scaling, multi-region deployments, and resilient workloads.

Technical Leadership

• Guide engineering teams through all phases of the SDLC, ensuring solutions meet performance, resilience, and regulatory expectations.

• Conduct architecture and design reviews, including performance benchmarking and failure-mode analysis.

• Lead architecture governance sessions and champion best practices for scalable and secure banking applications.

Stakeholder Collaboration

• Engage with business stakeholders to translate complex payment and financial requirements into robust technical architectures.

• Work closely with product, engineering, compliance, DevOps, and QA teams to validate solutions and ensure seamless delivery.

• Present architectures to senior executives and non-technical audiences clearly and effectively.

Integration & Modernization

• Architect complex integrations across enterprise systems, payment gateways, fraud systems, core banking, and third-party fintech partners.

• Ensure low-latency, high-throughput system performance for real-time and near-real-time transaction processing.

Security, Compliance & Risk

• Ensure all payment solutions adhere to strict financial security and regulatory standards (e.g., PCI-DSS, ISO 27001, MAS, SOX, GDPR).

• Lead threat modeling, data protection architecture, and secure-by-design practices.

• Architect HA/DR strategies, including multi-zone/multi-region deployment, RTO/RPO planning, and resilience testing.

Experience

• 10+ years of experience in solution architecture, enterprise application design, and software engineering.

• RTGS Expertise: Deep understanding of clearing and settlement (e.g., SWIFT, Fedwire, or local RTGS systems).

• Financial Standards: Proven experience with ISO 20022, MT/MX messaging, and transaction monitoring.

• Regulatory Knowledge: Familiarity with PCI-DSS, AML/CTF regulations, and regional central bank mandates.

• Demonstrated expertise in massively scalable architectures , distributed systems, and real-time transaction processing.

• Experience with HA (High Availability) and DR (Disaster Recovery) design and implementation. 

Technical Skills - Deep expertise in:

• Messaging: ISO 20022, Kafka, RabbitMQ.

• Architecture Patterns: Event Sourcing, Saga Pattern, and Idempotency.

• Data & Security: HSM integration, mTLS, SQL/NoSQL, and Distributed Ledgers.

• Cloud: AWS/Azure/GCP (specifically multi-region resilience)
