Tata Consultancy Services in Plano, TX is seeking a senior software architect/engineer to design, build, and optimize scalable Java backend services and align architecture with event-driven patterns.

You will lead design reviews, mentor engineers, and collaborate with frontend teams to deliver contract-first REST/GraphQL APIs, Kafka-based messaging, and robust Oracle-based data solutions while emphasizing quality throughout the SDLC.

Qualifications

• Core Java: deep concurrency, JVM tuning, generics, collections, Java 8+ functional programming.
• Spring ecosystem: Spring Boot/Data/Security/Cloud; explain runtime DI mechanics.
• Distributed messaging: Kafka with partitioning, retention, replication, delivery guarantees.
• Relational databases: Oracle SQL/PLSQL; debugging, isolation levels, complex queries.

Responsibilities

• Design, build, and maintain highly scalable backend services using Java, Spring Boot, and event-driven architectures.
• Evaluate landscapes and refactor using patterns like DDD, Event Sourcing, Circuit Breakers.
• Lead design reviews and develop technical blueprints mapping system interactions and data flows.
• Doctorate responsibility items skipped: not present in HTML.

Job description

• Core Java: Deep comprehension of concurrency models, memory management (JVM tuning), generics, Collections framework, and functional paradigms introduced in Java 8+.
• Spring Ecosystem: Comprehensive experience with Spring Boot, Spring Data, Spring Security, and Spring Cloud. Must be able to explain how dependency injection functions at a runtime level.
• Distributed Messaging: Production experience using Apache Kafka. You should understand partitioning strategies, retention policies, replication factors, and delivery guarantees (at-least-once vs. exactly-once).
• Relational Databases: Proven Oracle SQL and PL/SQL skills. Proven capability in debugging locks, understanding isolation levels, and optimizing complex joins or batch processing jobs.
• DevOps : Experienced in CI/CD pipelines, containerization (Docker/Kubernetes), cloud deployments, and infrastructure automation to enable reliable and scalable software delivery.
• Quality Engineering Mindset: Designs robust, scalable automation frameworks using Selenium, Java, API, and UI automation while embedding quality throughout the SDLC.
• Design, build, and maintain highly scalable backend services using Java, Spring Boot, and event-driven distributed architectures.
• Evaluate existing application landscapes and identify areas where refactoring to proper design patterns (e.g., Domain-Driven Design, Event Sourcing, Circuit Breakers) improves maintainability and system resilience.
• Lead design reviews and construct technical blueprints that map clear system interactions and data flows.
• Author highly optimized, transactional schemas and queries in Oracle RDBMS; diagnose slow-running queries using execution plans and introduce indexing or caching schemas appropriately.
• Design event streams and topic schemas in Apache Kafka that guarantee data consistency, fault tolerance, and minimal latency across independent microservices.
• Manage complex distributed transaction patterns (e.g., Saga Pattern) where traditional ACID properties across single databases are unachievable.
