Senior Java Developer - Spring Boot/Microservices Architecture

Description :

Join a fast-growing engineering organization building highly scalable backend systems and B2B SaaS platforms for global customers. You will architect, design, and deliver resilient, fault-tolerant services optimized for high throughput, low latency, and rapid iteration.

Role & Responsibilities :

- Design, build, and maintain microservices and backend components using Java (8/11/17) and Spring Boot, ensuring production-grade stability, observability, and performance.

- Define and implement RESTful APIs including request/response models, contract versioning, API governance, and backward compatibility.

- Optimize data persistence and schema design using Hibernate/JPA with relational databases (PostgreSQL/MySQL/Oracle); write efficient SQL queries and tune performance bottlenecks.

- Lead solution design discussions with architects, contribute to architectural blueprints, integration patterns, fault tolerance, caching strategies, and distributed systems design.

- Establish engineering best practices: automated unit/integration testing, code reviews, CI/CD workflows, modularized codebases, and clean architecture principles.

- Implement production observability using metrics, structured logging, distributed tracing, and dashboards (ELK, Prometheus, Grafana).

- Drive root-cause analysis and long-term fixes for production incidents; contribute to reliability engineering, capacity planning, and performance benchmarking.

- Mentor junior developers, conduct design walkthroughs, and guide teams on technical decision-making and system evolution.

Must-Have Skills :

- Strong proficiency in Java, Spring Boot, Spring Cloud, and microservices architecture.

- Hands-on experience with RESTful APIs, Hibernate/JPA, and relational database design.

- Expertise in multithreading, concurrency, JVM internals, memory management, and performance tuning.

- CI/CD experience with Git-based workflows and automated build pipelines.

Preferred Skills :

- Docker-based containerization and Kubernetes orchestration.

- AWS cloud services: ECS/EKS, Lambda, RDS, API Gateway, SQS/SNS.

- Experience with caching layers (Redis), event streaming (Kafka), and asynchronous processing.

- Knowledge of API security, OAuth2, JWT, and distributed application patterns.

Qualifications :

- Bachelors degree in Computer Science or related field preferred.

- Proven backend engineering experience of 6+ years delivering scalable Java services.

- Demonstrated ability to lead complex projects, influence architecture, and own end-to-end features.

Culture & Benefits :

- Hybrid work model with structured onsite collaboration.

- Engineering-led culture with strong focus on technical mentorship, knowledge-sharing, and certifications.

- Fast-paced product environment with autonomy, impact, and clear career progression.
