Java Backend Developer

As a Java Backend Developer, you will design and maintain microservices architecture using Spring Boot, develop RESTful APIs, and implement event-driven architectures with Apache Kafka. Your role includes ensuring high performance and reliability of our system while mentoring junior developers, conducting code reviews, and collaborating with cross-functional teams to deliver excellent software solutions.

To qualify for the Java Backend Developer role, you should have a Bachelor’s degree in computer science or engineering, alongside 3 to 5 years of hands-on experience in software development focused on microservices. Strong proficiency in Spring Boot, Kafka, Java (preferably version 8 or later), as well as experience with cloud platforms like AWS or Azure, is essential.

Ideal candidates for the Java Backend Developer role will be proficient in Spring Cloud, RESTful services, SQL and NoSQL databases, Docker, Kubernetes, and CI/CD tools like Jenkins or GitLab CI. Familiarity with API design, performance testing tools like JMeter, and monitoring tools like Prometheus will also be a significant advantage.

Our company is committed to professional development for our Java Backend Developers. We provide opportunities for mentorship, knowledge sharing, and participation in Agile ceremonies. You will be encouraged to explore new technologies, work on challenging projects, and receive constructive feedback through code reviews to continually improve your skills.

We foster an inclusive, collaborative, and dynamic company culture for our Java Backend Developers. You'll find an environment that values communication, teamwork, and innovation. Our Agile practices facilitate close collaboration among developers, Product Management, QA, and DevOps teams, enabling you to make meaningful contributions and grow your career.

In my experience, I start by defining the business requirements and breaking them down into smaller, manageable microservices. I utilize Spring Boot to create RESTful APIs, ensuring that each service can be deployed independently and is loosely coupled. I monitor and document each microservice, optimizing for performance and scalability.

To optimize microservices performance, I analyze system metrics and identify bottlenecks. I employ techniques such as caching, load balancing, asynchronous processing, and database query optimization. Moreover, I use monitoring tools like Prometheus to keep a real-time eye on system performance and make necessary adjustments.

Security is a top priority in my microservices. I implement best practices such as OAuth2 for authentication, secure communication via HTTPS, and validating inputs to prevent attacks. I conduct regular security audits and use tools like SonarQube to identify vulnerabilities in the code.

I've worked extensively with Kafka to create event-driven architectures. I design producers and consumers to handle data streams, implement topic partitioning for scalability, and ensure reliable message delivery. Understanding message ordering and retention policies has empowered me to build robust data pipelines and streamline processing workflows.

In code reviews, I focus on constructive feedback. I assess code for readability, performance, and adherence to best practices. During the review process, I encourage open discussions about alternative solutions and promote knowledge sharing, ensuring that junior developers can learn from the experience.

I believe mentoring is about providing guidance and support while fostering independence. I start by partnering with junior developers on tasks, helping them understand the intricacies of our architecture and coding standards. I encourage them to ask questions and gradually take ownership of their work to build confidence.

I typically use tools like Jenkins and GitLab CI for CI/CD. I design pipelines that automate testing and deployment processes. This includes establishing triggers for build processes, running automated tests, and deploying to staging and production environments, ensuring a smooth and efficient workflow.

I stay current by attending industry conferences, participating in online courses, and being part of tech communities. I regularly experiment with new tools and practices in personal projects and follow relevant blogs and forums to ensure I’m aware of the latest developments in technology.

In one project, I encountered performance issues due to inefficient API calls. I refactored the microservice to implement caching for frequently requested data and introduced asynchronous processing for non-blocking operations, significantly improving response times and overall system performance.

When conflicts arise, I advocate for open communication. I facilitate discussions to understand different perspectives and promote a collaborative resolution. By focusing on common goals and considering the project's best interests, I work to create a harmonious team environment.
