Job description

Role Overview

We are seeking a highly skilled Software Engineer with strong expertise in Java, Apache Kafka, and distributed systems to design and build scalable, resilient, event-driven platforms and shared infrastructure services. The ideal candidate will have experience developing high-throughput messaging systems, reusable platform frameworks, and cloud-native applications that operate reliably at enterprise scale.

Key Responsibilities

Backend & Platform Development

• Design and develop high-performance backend services and platform components using Java.
• Build reusable frameworks, libraries, and APIs used by multiple application teams.
• Develop shared infrastructure capabilities that improve developer productivity and operational efficiency.
• Collaborate with architects and engineering teams to establish engineering standards and best practices.

Event-Driven Systems

• Design and implement event-driven architectures using Apache Kafka.
• Develop reliable producer and consumer services with strong guarantees around throughput, ordering, and resiliency.
• Implement message routing, filtering, transformation, and event processing patterns.
• Build scalable systems capable of handling large transaction volumes with low latency.

Reliability & Resiliency Engineering

• Implement fault-tolerant solutions for handling infrastructure and application failures.
• Design retry, recovery, circuit breaker, and fallback strategies.
• Build observability capabilities including metrics, logging, tracing, and alerting.
• Participate in production support and performance optimization activities.

Distributed Systems Engineering

• Design systems that operate across multiple services, clusters, and environments.
• Solve challenges related to consistency, scalability, concurrency, and data reliability.
• Optimize throughput, latency, and resource utilization for large-scale distributed applications.

Required Qualifications

Core Technical Skills

• Strong hands-on experience with Java;
• Deep understanding of object-oriented design, design patterns, concurrency, and multithreaded programming.
• Strong experience with Spring Boot, microservices architecture, and REST APIs.
• Extensive hands-on experience with Apache Kafka and production-grade event-driven systems.
• Experience designing scalable distributed systems and working with relational and NoSQL databases.

Kafka Expertise

• Kafka producers and consumers, consumer groups, partitioning strategies, and rebalancing.
• Offset management, delivery semantics, idempotency, Kafka transactions, and exactly-once processing.
• Schema evolution, compatibility, serialization formats, and contract management.
• Performance tuning, capacity planning, high availability, and failover strategies.

The successful candidate will help shape reliable, scalable platform capabilities that make event-driven development simpler and safer for engineering teams. Required Qualifications
