Full-Stack Developer

Design and develop scalable, enterprise-grade back-end services using Java (11/17+) and Spring Boot, following clean architecture and SOLID principles. Build and expose RESTful APIs; design event-driven architectures using Apache Kafka for asynchronous data processing and inter-service communication. Develop responsive, accessible front-end applications using React, JavaScript (ES6+), and CSS - ensuring consistent cross-browser and cross-device experiences. Architect and implement microservices solutions - defining service boundaries, API contracts, and communication patterns across distributed systems. Design and optimize relational data models in PostgreSQL; write complex SQL for business logic, reporting, and data integrity. Champion test-driven development using JUnit; contribute to code reviews and maintain high engineering standards across the codebase. Collaborate with DevOps on CI/CD pipelines, containerization, and deployment; manage source control workflows and branching strategies in Git. Engage in system design discussions; contribute to architecture decisions, technical documentation, and cross-team engineering guilds. Actively participate in agile ceremonies - sprint planning, backlog grooming, retrospectives - and support the delivery of high-quality releases.

Must-Have 8+ years of professional software development experience with a balanced full-stack profile. Deep expertise in Enterprise Java (11/17+) and Spring Boot - including Spring Security, Spring Data JPA, and Spring Cloud components. Hands-on experience designing and consuming RESTful APIs; understanding of API versioning, pagination, error handling, and contract testing. Production experience with Apache Kafka - topics, partitions, consumer groups, and event-driven patterns. Proven ability to design and decompose microservices architectures - service discovery, API gateways, circuit breakers, and distributed tracing. Strong React proficiency: component architecture, hooks, state management (Redux/Context API), and integration with REST/GraphQL backends. Solid JavaScript (ES6+) skills and CSS competence - including responsive layout, Flexbox/Grid, and CSS preprocessors or CSS-in-JS approaches. Disciplined Git workflow - branching strategies (GitFlow/trunk-based), pull request hygiene, merge conflict resolution. Test-driven development with JUnit; experience with Mockito and integration testing frameworks. Strong SQL skills and hands-on experience with PostgreSQL - schema design, indexing, query optimization, and stored procedures. Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent industry experience).

Nice-to-Have Skills:

Candidates with the following experience will be given strong preference: Experience with business rules engines - Drools or jBPM - for externalizing and managing complex decision logic. Hands-on with MongoDB or other NoSQL document stores; ability to choose the right database paradigm for the use case. Strong system design sensibility - designing for scale, resilience, observability, and maintainability in distributed systems. Appreciation for UI/UX principles - accessibility (WCAG), design systems, and working closely with UX designers to implement pixel-accurate interfaces. Familiarity with cloud architecture patterns (AWS, Azure, or GCP) - multi-region deployments, managed services, and cloud-native design. Experience with container orchestration on OpenShift or Kubernetes - Helm charts, namespaces, resource management, and rolling deployments. CI/CD experience with Jenkins - pipeline-as-code (Jenkinsfile), build automation, and environment promotion. Infrastructure-as-Code using Terraform - provisioning and managing cloud resources in a repeatable, version-controlled manner. Security-minded development: OAuth2 / OIDC for identity federation, mTLS for service-to-service authentication, and secrets management using HashiCorp Vault.
