Lead Software Engineer; Java, Microservices

The Role:

This role is for a seasoned Java engineer who will be instrumental in building and shaping the backbone of our enterprise applications. You will be taking ownership of designing and developing complex, distributed systems using a modern Java-based stack, focusing on microservices and real-time data processing. This position is equivalent to a technical lead or principal engineer in the market, requiring deep expertise in system architecture and the ability to mentor other developers.

• Design, develop, and maintain scalable, high-performance Java-based applications using the Spring Framework (Spring Boot, Spring MVC, Spring Data, Spring Security).
• Build and maintain robust, secure, and efficient RESTful APIs and microservices to support critical business functions.
• Design and implement event-driven architectures using Apache Kafka, including the development of producers, consumers, and stream processing applications for real-time data handling.
• Manage and optimize Kafka infrastructure, including topics, partitions, and consumer groups to ensure high availability and fault tolerance.
• Collaborate with architects and technical leads to define and refine system architecture, ensuring the scalability, resilience, and high availability of our microservices ecosystem.
• Design and optimize Mongo
  
  DB schemas, indexing strategies, and aggregation pipelines for efficient data storage and retrieval.
• Write clean, maintainable, and well-documented code, adhering to industry best practices and established design patterns.
• Champion code quality by performing thorough code reviews, implementing comprehensive testing strategies (unit, integration, and end-to-end), and mentoring junior developers.
• Work with Dev Ops teams to implement and manage CI/CD pipelines for automated builds, testing, and deployments in cloud environments (e.g., AWS, Red Hat Open Shift).
• Utilize containerization tools like Docker and orchestration platforms like Kubernetes for deploying and managing applications.
• Collaborate closely with product managers, business analysts, and other cross-functional teams to translate complex business requirements into technical solutions.
• Proactively monitor application performance, troubleshoot, and resolve production issues in a timely and efficient manner.

• 6+ years' professional experience in Java development with a strong emphasis on building backend, distributed systems.
• Expert-level proficiency in the Spring Framework, including Spring Boot, Spring MVC, Spring Data, and Spring Security.
• Extensive hands-on experience designing, building, and maintaining a microservices architecture and creating RESTful APIs.
• Deep expertise in Apache Kafka, including its architecture (topics, partitions, replication), and practical experience developing producers, consumers, and stream processing applications.
• Strong proficiency with Mongo
  
  DB, including data modeling, schema design, indexing, and writing efficient aggregation pipelines.
• Hands-on experience with containerization technologies such as Docker and container orchestration with Kubernetes.
• Experience with deploying and managing applications on cloud platforms (e.g., AWS, Azure, GCP).
• Proven experience with CI/CD principles and tools like Jenkins, Git Lab CI/CD, or Git Hub Actions.
• Solid understanding of object-oriented programming (OOP) principles and software design patterns.
• A strong advocate for testing, with experience in unit testing and Test-Driven Development (TDD).

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related technical field, or industry equivalent experience required.
