Role Overview: -
We are seeking a high -caliber, deeply technical Principal Solution Architect to drive technical customer
engagement, product evangelism, and solution architecture for our enterprise banking clients. Based out
of our Chennai office, you will be the definitive technical voice of our product ecosystem.
Your mission is two -fold: maintain absolute mastery over the complex, fast -evolving Indian payments
landscape, and act as a trusted technical advisor to leadership teams at major commercial, retail, and
cooperative banks. You will bridge the gap between core engineering and executive banking clients—
delivering deep -dive technical demonstrations, articulating feature differentiation, and instilling absolute
confidence that our architecture can flawlessly handle mission -critical transaction volumes.

Core Responsibilities: -

1. Technical Customer Evangelism & Value Demonstration 

● High -Impact Technical Demos: Lead end -to -end technical product demonstrations for C -suite
executives, IT heads, and chief architects at prospective banks. 

● Feature Differentiation: Clearly articulate how our platform stands out from legacy systems in
terms of throughput, low latency, microservices architecture, automated failover mechanisms, and
total cost of ownership (TCO). 

● Instilling Banking Confidence: Address complex architectural, infrastructure, and deployment
queries on the spot. Proactively mitigate risk concerns to convince highly risk -averse banking
committees that our product will scale seamlessly to their needs. 

● Proof of Concept (PoC) Ownership: Scrutinize RFP/RFI requirements from banks, design tailored
technical solution blueprints, and oversee execution lines for high -stakes PoCs.

2. Payment Lifecycle & Architecture Mastery 

● End -to -End Lifecycle Ownership: Maintain an authoritative understanding of the full lifecycle of
Indian payment rails—including transaction switching, routing matrices, authorization loops, real
time clearing, multi -party settlement, automated reconciliation, and dispute/chargeback
management frameworks. 

● Technical Protocols: Demonstrate deep familiarity with payment messaging standards (ISO 8583,
ISO 20022, JSON/RESTful APIs), cryptographic hardware integrations (HSMs), and database
management systems optimized for heavy transaction concurrency.

3. Compliance & Regulatory Alignment 

● Indian Financial Guardrails: Ensure all solution architectures proposed to client banks perfectly
align with the latest Reserve Bank of India (RBI) mandates and National Payments Corporation of
India (NPCI) procedural guidelines. 

● Data & Security Mandates: Guide clients through our product's native compliance frameworks,
including PCI -DSS, data localization laws, card tokenization rules, and strict access control
guidelines.

1. Mandatory Industry Pedigree

● Payments Tech Background: You must have a proven track record of working on the
technical/engineering side of an established Indian payments technology company. Direct
experience at organizations providing payment switch/core -banking solutions is mandatory. 

● Banking Domain Trust: Minimum 8–12 years of core technical experience, with at least 3+ years in
a client -facing technical sales, solution engineering, or advisory role directly facing Indian banks.

2. Deep Transactional Expertise 

Extensive technical familiarity with the deployable life cycles of core Indian transaction products is
required: 

● Real -Time Retail Payments: UPI (Unified Payments Interface), IMPS, and AePS (Aadhar Enabled
Payment System). 

● High -Value & Batch Rails: NEFT, RTGS, and direct integrations with the RBI’s E -Kuber system. 

● Value -Added Systems: BBPS (Bharat Bill Payment System), NACH, and comprehensive
Card/POS/ATM switching ecosystems.

3. Exceptional Interpersonal & Communication Skills 

● The "Engine Room to Boardroom" Translator: Ability to debate low -level database deadlocks or
API structures with engineering teams in one hour, and deliver a polished, business -value driven
presentation to a Bank MD in the next. 

● High -Trust Consultant Mentality: A patient, educational approach to customer success. You do not
just sell features—you educate banking stakeholders on the structural evolution of modern fintech
infrastructure.
