Job Description

• We are seeking an experienced Senior Java Spring Boot Developer to join our team in designing and building next-generation, microservices-based solutions.
• You will play a critical role in the entire software development lifecycle, from domain modeling and architecture to coding, testing, and deployment.
• If you excel at tackling complex technical challenges, value high-quality code, and thrive in a fast-paced, agile environment, we'd love to have you on board.

Qualifications: Education & Experience

• Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience).
• Software development experience, with a strong focus on Java (Java 8+).
• Spring Boot in microservices architectures.

Technical Expertise

• Proven experience in Domain-Driven Design (DDD), including the ability to define bounded contexts and domain models effectively.
• Strong knowledge of RESTful API development, JSON/XML payloads, and API versioning best practices.
• Experience with Spring Data JPA, SQL/NoSQL databases, and best practices for data persistence and caching.
• Familiarity with cloud services (AWS, Azure, GCP) and container technologies (Docker, Kubernetes) is a plus.
• Hands-on experience with CI/CD tools and processes, as well as test-driven development (TDD) and behavior-driven development (BDD) methods.

Soft Skills

• Excellent communication and collaboration skills, able to articulate technical concepts to both technical and non-technical stakeholders.
• Strong problem-solving and analytical skills, with the ability to handle complex tasks and troubleshoot effectively.
• A leadership mindset-capable of mentoring team members, driving best practices, and influencing architectural decisions.

Bonus Skills

• Experience with event-driven architectures (RabbitMQ, Kafka).
• Advanced knowledge of observability (monitoring, logging, tracing) and performance tuning at scale.
• Familiarity with security best practices (OAuth2, JWT, encryption, etc.).

Key Responsibilities

Architecture & Design

• Lead the design and implementation of microservices using Spring Boot and other Spring technologies (Spring Data, Spring Cloud, Spring Security, etc.).
• Apply Domain-Driven Design (DDD) principles to define bounded contexts, ubiquitous language, and domain models that align with business capabilities.
• Collaborate with cross-functional teams (Architects, DevOps, QA, Product Owners) to ensure scalable, resilient, and maintainable solutions.

Hands-On Development

• Write clean, efficient, and testable Java code following best practices and coding standards.
• Implement RESTful APIs (Level 2 or Level 3) with robust data contracts, versioning strategies, and error-handling conventions.
• Build and maintain unit, integration, and end-to-end test suites, ensuring high code coverage and reliability.

Performance & Reliability

• Analyze system performance and optimize application code, database queries, and resource utilization to meet SLAs.
• Utilize caching, messaging, and other architectural patterns (e.g., Circuit Breaker, Retry) for fault tolerance and high availability.

Continuous Integration / Continuous Delivery (CI/CD)

• Integrate code into CI/CD pipelines (Jenkins, GitLab CI, or Azure DevOps) for automated builds, tests, and deployments.
• Collaborate with DevOps engineers to containerize services using Docker and manage deployments with Kubernetes or similar orchestration tools.

Collaboration & Leadership

• Participate in agile ceremonies (daily stand-ups, sprint planning, retrospectives), providing technical leadership and insights to the team.
• Proactively identify risks, bottlenecks, and technical debt, proposing innovative solutions to maintain project momentum.

Documentation & Knowledge Sharing

• Maintain clear and comprehensive documentation of code, architecture, design decisions, and domain models.
• Share knowledge and promote a culture of continuous learning and improvement within the engineering team.
