Senior Java Backend Engineer

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.

Responsibilities

• We actively embrace GenAI-assisted engineering (Devin, GitHub Copilot, Cursor) to automate boilerplate, accelerate unit testing, and achieve high engineering velocity.
• Design, build, and maintain production-grade REST APIs and microservices using Java 21/25 and Spring Boot .
• Build resilient ETL and reconciliation services that ingest, validate, and deduplicate complex monthly datasets from multiple upstream sources into a unified data model.
• Design relational schemas (PostgreSQL / Oracle), optimize complex SQL queries, and implement transactional data integrity, staging layers, and immutable audit logs.
• Leverage AI-powered developer tooling (Devin, Copilot, Cursor) for rapid prototyping, component scaffolding, and automated test coverage.
• Drive high code quality through TDD/BDD (JUnit 5, Mockito), automated CI/CD pipelines, containerization (Docker/OpenShift), and code reviews.
• Act as a technical pillar within the Pune agile squad, collaborating with global teams and mentoring junior engineers.

Requirements

• 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 .
• unit testing, integration testing, and mock frameworks (JUnit, Mockito, Testcontainers).
• Experience with modern DevOps pipelines (Git, Maven/Gradle, Jenkins/Tekton, Docker, Linux).
• Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience.
• Ability to operate with limited direct supervision, make sound architectural choices, and deliver features independently.
• Strong English communication skills and ability to collaborate across distributed global teams (India, UK, US).

Preferred

• Partner with or contribute to the React/TypeScript frontend to integrate APIs seamlessly with data grids, curation drawers, and bulk Excel upload workflows.
• 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).
