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.
