Job description

Role: Sr Java Spring Security Engineer

Location: Pune

Work Mode: Hybrid (2 Days in a week)

Experience: 8+ years

Role & responsibilities

• Java (modern LTS, 21+) as the primary language deep, current, hands-on expertise is essential.
• Spring Boot 3.x and the wider Spring ecosystem (Spring Web / WebFlux, Spring Security, Spring Data, Spring Cloud); reactive programming with Project Reactor is a strong plus.
• Gradle (Kotlin DSL), version catalogs, multi-repo / composite builds, and CI/CD pipelines (Jenkins, Git-based workflows).
• OpenAPI-first API design with code generation, API linting/governance, and disciplined versioning.
• Relational databases and schema evolution: PostgreSQL, JPA/Hibernate, Flyway migrations, query performance and data modelling.
• Event-driven and asynchronous messaging: Apache Kafka, event/command-driven or CQRS-style architectures (e.g. Axon), and reliable delivery patterns such as the transactional outbox.
• Containerised delivery and cloud-native operations: Docker, orchestration platforms, configuration and secret management (e.g. HashiCorp Vault), 12-factor configuration.
• Observability in production: structured logging, metrics, tracing, dashboards and alerting including how to instrument systems that must never log sensitive data.
• Git and modern collaborative development practices (PR-based workflows, code review culture, semantic versioning).
