We are seeking an accomplished Java Backend Architect to lead the design, modernization, and delivery of large-scale, cloud-native platforms. You will define end-to-end backend architecture, establish engineering standards, and guide cross-functional teams in building secure, resilient, and high-performance distributed systems.

This is a hands-on architecture leadership role requiring deep expertise in Java, microservices, event-driven design, cloud platforms, and enterprise integration patterns.

Key Responsibilities

- Define and own the backend solution architecture for complex, mission-critical enterprise applications.
- Design scalable, loosely coupled microservices using Java 17/21, Spring Boot, Spring Cloud, and modern design patterns.
- Lead high-level and detailed design activities, including architecture decision records, solution documents, API contracts, and integration blueprints.
- Architect event-driven systems using Apache Kafka, RabbitMQ, or equivalent messaging and streaming technologies.
- Design RESTful and GraphQL APIs with solid focus on versioning, security, performance, observability, and developer experience.
- Lead modernization of legacy monolithic applications into cloud-native, domain-driven microservices.
- Define data architecture and persistence strategies across relational and NoSQL databases, including PostgreSQL, Oracle, MongoDB, Cassandra, or DynamoDB.
- Establish caching, resilience, fault-tolerance, and performance-tuning strategies using Redis, Hazelcast, circuit breakers, rate limiting, and asynchronous processing.
- Guide cloud-native deployment and operations on AWS, Azure,



or GCP using Docker, Kubernetes, serverless components, and infrastructure-as-code practices.
- Drive CI/CD maturity through automated build, test, deployment, and release pipelines using Jenkins, GitHub Actions, GitLab CI, or Azure DevOps.
- Define observability standards using Prometheus, Grafana, ELK/OpenSearch, distributed tracing, and application performance monitoring.
- Establish security-by-design practices, including OAuth2, OpenID Connect, JWT, IAM, encryption, secrets management, and secure API gateways.
- Conduct architecture reviews, technical design reviews, and code reviews; resolve high-impact production issues through root-cause analysis.
- Mentor senior engineers and technical leads, promote engineering best practices, and influence technology adoption across teams.
- Partner with product, infrastructure, security, data, and business stakeholders to translate complex requirements into scalable technical solutions.
- Evaluate emerging technologies, including AI-assisted development tools, and recommend practical adoption aligned with engineering goals.

Required Skills and Experience
- 10–15 years of overall software engineering experience,



with at least 5–7 years in backend architecture or technical leadership.
- Expert-level proficiency in Java 11/17/21, including concurrency, multithreading, streams, virtual threads, JVM performance, and functional programming.
- Deep hands-on experience with Spring Boot, Spring Cloud, Spring Security, Spring Data, Hibernate/JPA, and REST API design.
- Proven experience architecting and delivering distributed systems, microservices, and event-driven architectures.
- Strong expertise with Apache Kafka, including topic design, consumer groups, partitioning, idempotency, exactly-once considerations, and stream processing.
- Strong understanding of DDD, CQRS, Saga patterns, API-led integration, eventual consistency, and distributed transaction handling.
- Hands-on experience with Docker, Kubernetes, Helm, and cloud platforms such as AWS, Azure, or GCP.
- Strong experience with relational and NoSQL databases, data modeling, indexing, query optimization, and performance tuning.
- Solid knowledge of caching strategies, load balancing, horizontal scaling, high availability, disaster recovery, and capacity planning.
- Experience with CI/CD pipelines, DevOps practices, Git-based workflows, and automated testing strategies.
- Strong understanding of application security, identity and access management, API security, and secure cloud architecture.
- Experience with observability tools such as Prometheus, Grafana, ELK/OpenSearch, Zipkin, Jaeger, or cloud-native monitoring services.
- Excellent communication, stakeholder management, and technical leadership skills.
