Job description

Senior Java Backend Developer

Experience: 4-5 years Company: Ipsator Analytics Private Limited Location: Bangalore Employment Type: Full‑time No. of Vacancies: 1 ₹16L – ₹24L No equity

Looking for Immediate Joiners

About the Role: We are looking for a senior backend engineer who goes beyond writing code, someone who takes end-to-end ownership of features, drives architectural decisions, and actively elevates the engineering team around them. You will be a primary technical voice in your squad, partnering with product and cross-functional teams to deliver high-performance, scalable backend systems built on Java and modern cloud-native practices.

Key Responsibilities

• Own the design and delivery of complex backend features end-to-end, from architecture definition and technical specification through implementation, testing, and production deployment.
• Design, build, and maintain robust, well-documented RESTful web services that serve high‑traffic, mission-critical workloads.
• Act as a technical mentor to junior and mid-level engineers, conducting code reviews, pair‑programming sessions, and sharing best practices in system design and Java development.
• Identify performance bottlenecks, lead JVM tuning and garbage collection optimization, and improve overall application throughput and latency.
• Collaborate closely with product managers, front‑end teams, and QA engineers in agile ceremonies, standups, sprint planning, and retrospectives.
• Maintain and improve code quality standards, champion testing culture (unit, integration, performance tests) and drive adoption of engineering best practices across the team.
• Work with AWS services (EC2, RDS, S3, SQS, etc.) to architect cloud‑native solutions and contribute to CI/CD pipeline improvements.
• Manage tasks independently and take full ownership of deliverables — proactively communicating risks, dependencies, and timelines to stake

Required Technical Skills

• 4–5 years of hands‑on experience in Java and J2EE application development, with deep command over core Java concepts, OOP, and design patterns.
• Proficiency in industry‑standard frameworks — Spring Boot, Spring MVC, Hibernate/JPA, and/or the Play framework.
• Strong understanding of JVM internals — memory model, garbage collection, thread management, and performance profiling tools (JProfiler, VisualVM, Async Profiler).
• Experience designing and building RESTful APIs — including API versioning, authentication, and rate limiting strategies.
• Solid system design skills — ability to architect distributed systems, design for fault tolerance, scalability, and high availability.
• Strong SQL proficiency and RDBMS experience (PostgreSQL/MySQL). Hands‑on knowledge of data persistence, transaction management, and query optimization.
• Experience with AWS services (EC2, RDS, S3, SQS/SNS, Lambda) and working knowledge of cloud‑native architectures.
• Demonstrated ability to own and deliver projects independently — with clear communication, risk identification, and self‑direction.
• Proven mentoring ability or strong desire to grow into a technical leadership role.
