Senior Java Developer

We are seeking a Senior Java Developer with Angular to join our team and spearhead the remediation of security vulnerabilities across a portfolio of business-critical enterprise applications.
The perfect candidate brings strong hands-on expertise in Java, Spring Framework / Spring Boot, and Angular, and feels confident owning complex enterprise applications, driving architectural decisions, performing in-depth analysis of security findings, and designing secure, scalable, and maintainable solutions across both backend and front-end layers.
The core focus of the role is Java/Spring development and security vulnerability remediation, with Angular applied to support, evolve, and maintain front-end components when needed. As a senior engineer, you will also be expected to mentor fellow team members, shape technical direction, and serve as a trusted advisor to stakeholders.
Responsibilities
Lead the analysis and remediation of security vulnerabilities across the applications, including defining remediation strategies and best practices
Design, develop, modify, and maintain backend functionality with Java and Spring Boot, ensuring high standards of quality, performance, and security
Evolve and enhance existing microservice-based architectures and REST APIs, proposing improvements where appropriate
Work with relational databases, including PostgreSQL, tune queries, and resolve complex application/database integration issues
Maintain, refactor, and improve front-end functionality using Angular
Design and implement solutions leveraging Kafka and event-driven integrations where applicable
Investigate complex legacy code and deliver fixes that address vulnerabilities without disrupting business functionality
Drive the upgrade of vulnerable libraries, frameworks, and application dependencies, including planning and risk mitigation
Perform code-level remediation guided by security findings, threat modeling, and secure development practices
Diagnose and resolve complex issues arising from security fixes, dependency upgrades, or legacy implementations
Write clean, maintainable, and secure code across backend and front-end layers, and define coding standards for the team
Lead code reviews, testing strategies, and validation of implemented fixes

Deep hands-on expertise in Spring Framework / Spring Boot, including dependency injection, application configuration, REST services, data access, security, and advanced enterprise development patterns
Strong understanding of microservice architecture and communication patterns, including service boundaries, REST-based integrations, error handling, resiliency patterns, observability, and troubleshooting of distributed systems
Advanced skills in SQL and relational databases, including complex queries, joins, indexes, transactions, data access patterns, performance tuning, and schema design
Solid hands-on proficiency in Angular and TypeScript, sufficient to investigate, maintain, refactor, and enhance existing front-end functionality
