Senior Software Engineer at Ezra

The Senior Software Engineer is a core technical leader responsible for the hands-on development and architecture of our mission-critical backend platform.

Main Objectives & Responsibilities:

• System Design & Implementation: Lead the end-to-end design, development, and deployment of robust, highly scalable, and secure event-driven microservices using Java and Spring Boot.
• Quality Assurance: Champion the adoption of engineering best practices, particularly Test-Driven Development (TDD), to ensure code quality, maintainability, and long-term stability.
• Collaboration: Work closely with Product Managers, DevOps, and other engineering teams to translate complex business requirements into technical specifications and delivered features.
• Mentorship: Provide technical guidance and mentorship to junior team members, raising the overall technical bar of the engineering organization.

Key responsibilities:

Backend Development

• Design, develop, and maintain high-performance backend services using Java Spring Boot (or similar frameworks) and Clojure.
• Adhere to clean code principles and industry best practices in all development efforts.
• Ensure code quality through pair programming, code reviews, and other collaborative development methods.

Event-Driven Architecture

• Implement and maintain event-driven systems using message brokers (e.g., Kafka, RabbitMQ, or cloud-native equivalents).
• Work on publish/subscribe patterns and streaming data pipelines to ensure real-time data processing and system responsiveness.
• Optimize event flow for performance and scalability.

Test-Driven Development (TDD)

• Apply TDD principles throughout the software development lifecycle to deliver robust, maintainable solutions.
• Write comprehensive unit tests, integration tests, and end-to-end tests.
• Ensure high test coverage and effectively diagnose, document, and fix bugs.

Architecture and Design

• Collaborate with architects and senior engineers to define microservices architecture and component interaction.
• Contribute to architectural discussions and decision-making processes, ensuring scalability, security, and maintainability of solutions.
• Integrate best practices for secure coding, data privacy, and compliance.

Performance Optimization

• Monitor system performance, identify bottlenecks, and implement solutions for performance tuning.
• Conduct profiling, load testing, and implement caching strategies to enhance system response times.
• Work closely with the DevOps team to optimize CI/CD pipelines for quick and reliable deployments.

Collaboration and Leadership

• Mentor junior engineers on best practices, coding standards, and new technologies.
• Collaborate with product managers, QA engineers, and DevOps to deliver features on time and with high quality.

Qualifications and Experience:

• Bachelor’s degree in Computer Science, Software Engineering, or a related field.
• 5+ years of professional experience in software development, preferably in a modern backend environment.
• Strong proficiency in Java and proven, hands-on experience developing production-grade applications with Spring Boot.
• Expertise in designing, building, and operating event-driven microservices architectures.
• Proven ability to apply and advocate for Test-Driven Development (TDD) methodologies.
• Direct experience with message brokers/queues (e.g., Kafka, RabbitMQ) for inter-service communication.
• Solid knowledge of relational and NoSQL databases, caching layers (e.g., Redis), and RESTful API design.
• Working experience with CI/CD pipelines (e.g., Jenkins, GitLab CI) and DevOps practices.
• Experience with version control systems, particularly Git.
• Excellent communication skills, problem-solving abilities, and a collaborative, team-oriented mindset.
