We are looking for a Senior Java Backend Engineer (C12) in Pune to join the core engineering team building Vendor Master Central (VMC) —an enterprise-scale registry platform responsible for ingesting, reconciling, and managing millions of market data service records, contracts, and vendor hierarchies. This role is backend-first , centered on designing high-throughput ingestion pipelines, resilient Spring Boot microservices, clean RESTful APIs, and domain data models. Experience or interest in Full Stack development with React/TypeScript is a strong plus , enabling end-to-end feature ownership from backend services up to user-facing web tools. We actively embrace GenAI-assisted engineering (Devin, GitHub Copilot, Cursor) to automate boilerplate, accelerate unit testing, and achieve high engineering velocity. Key Responsibilities - Backend Microservices: Design, build, and maintain production-grade REST APIs and microservices using Java 21/25 and Spring Boot . - Data Ingestion & Processing: Build resilient ETL and reconciliation services that ingest, validate, and deduplicate complex monthly datasets from multiple upstream sources into a unified data model. - Data Modeling & Storage: Design relational schemas (PostgreSQL / Oracle), optimize complex SQL queries, and implement transactional data integrity, staging layers, and immutable audit logs. - Full Stack Collaboration (Bonus): Partner with or contribute to the React/TypeScript frontend to integrate APIs seamlessly with data grids, curation drawers, and bulk Excel upload workflows. - GenAI Velocity: Leverage AI-powered developer tooling (Devin, Copilot, Cursor) for rapid prototyping, component scaffolding, and automated test coverage. - Engineering Excellence: Drive high code quality through TDD/BDD (JUnit 5, Mockito), automated CI/CD pipelines, containerization (Docker/OpenShift), and code reviews. - Mentorship & Ownership: Act as a technical pillar within the Pune agile squad, collaborating with global teams and mentoring junior engineers. What We Are Looking For Core Backend Requirements: - 5–8+ years of hands-on software development experience with core focus on Java (21/25) and Spring / Spring Boot . - Strong foundation in RESTful API design , microservice architecture, and enterprise integration patterns. - Deep expertise in relational databases (SQL) , schema design, data indexing, transactions, and performance tuning (PostgreSQL, Oracle, or MySQL). - Solid experience building data ingestion, transformation, or batch processing pipelines . - Strong testing discipline: unit testing, integration testing, and mock frameworks (JUnit, Mockito, Testcontainers). - Experience with modern DevOps pipelines (Git, Maven/Gradle, Jenkins/Tekton, Docker, Linux). Nice-to-Have / Full-Stack Plus: - Experience or familiarity with React, TypeScript, or modern frontend SPAs (state management, component design, data grids). - Familiarity with client/server Excel file processing (.xlsx generation, bulk upload parsing). - Experience working with autonomous AI engineering agents (e.g., Devin ) or AI-assisted coding tools. - Experience with message brokers or event streaming (Kafka, MQ). Qualifications & Competencies - Education: Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience. - Autonomy & Judgment: Ability to operate with limited direct supervision, make sound architectural choices, and deliver features independently. - Communication: Strong English communication skills and ability to collaborate across distributed global teams (India, UK, US). - Risk & Controls: Sound understanding of secure coding practices, data governance, and enterprise security standards.
