### Job Summary

We are seeking a hands-on, high-impact Senior Technical Architect (Platform Backend)
to lead the architecture, scaling, and continuous evolution of our core platform
infrastructure. In this role, you will operate at the intersection of high-throughput
transactional systems and cloud-native architecture. You will be responsible for
driving high-level and low-level designs (HLD/LLD), establishing engineering guardrails,
optimizing complex data pathways, and collaborating directly with product and engineering
leaders to ensure absolute reliability, performance, and low latency at scale.

### Key Responsibilities

### System Design & Architectural Leadership

 * Own the end-to-end High-Level Design (HLD) and Low-Level Design (LLD) for core
   platform services, asynchronous processing components, and enterprise ERP/bank
   integration adapters.
 * Facilitate a smooth transition from monolithic legacy boundaries into clean, 
   highly cohesive microservices domains without impacting uptime or data integrity.
 * Establish architectural governance, lead Architecture Review Boards (ARBs), and
   review critical pull requests to safeguard code quality, clean architecture principles,
   and SOLID design patterns.

### Scalability, Performance & Reliability

 * Architect multi-tenant, cloud-native frameworks capable of handling high-concurrency
   and petabyte-scale financial transactions with strict SLAs.
 * Diagnose and eliminate system bottlenecks across distributed transactions, locking
   models, memory management, and network payloads.
 * Oversee zero-trust security compliance, fault-tolerance mechanisms, automated
   failover policies, and disaster recovery readiness.

### Data & Integration Architecture

 * Design robust relational (PostgreSQL/MySQL) and non-relational database schemas,
   complex indexing strategies, data partitioning models, and archival frameworks.
 * Scale event-driven architectures utilizing Apache Kafka or similar messaging 
   systems to manage reliable real-time data streaming and asynchronous decoupling.
 * Optimize high-throughput caching architectures (using Redis) to minimize database
   overhead for intensive financial computations.

### Engineering Culture & Execution

 * Act as a technical multiplier by mentoring senior engineers, driving proof-of-
   concepts (PoCs) for emerging technologies, and cultivating an environment of 
   fast, first-principles execution.
 * Collaborate closely with Product Management to scope technical roadmaps, decompose
   epic requirements into modular milestones, and proactively mitigate technical
   debt.

### Required Skills

### A technically deep engineering/product leader with

 * **Experience:** 12 – 16 years of professional software engineering experience,
   with a minimum of 3 years successfully operating in a Technical Architect or 
   Principal Engineer capacity for enterprise SaaS products.
 * **Core Backend Stack:** Expert-level mastery of Java (Java 17+), Spring Boot,
   Spring Cloud, and enterprise-grade backend frameworks. A profound understanding
   of JVM internals, garbage collection tuning, multi-threading, and high-concurrency
   programming models.
 * **Distributed Systems & Messaging:** Proven experience in building distributed
   microservices, RESTful APIs, gRPC, and event-driven architectures utilizing Apache
   Kafka or RabbitMQ.
 * **Database & Storage Expertise:** Advanced proficiency in SQL and NoSQL storage
   engines (PostgreSQL, MySQL, MongoDB, Redis). Hands-on capability with query execution
   plans, partitioning, and database tuning under heavy write/read loads.
 * **Cloud & DevOps Infrastructure:** Solid production experience with AWS (or Azure/
   GCP), containerization technologies (Docker), cluster orchestration (Kubernetes),
   and enterprise CI/CD deployment pipelines.
