No matter where you are located, you will join a dedicated, creative, and diverse community that will help you discover your fullest potential.

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
• Collaborate closely with developers, QA engineers, architects, product stakeholders, and other team members, offering technical guidance
• Mentor less experienced engineers and share knowledge throughout the team
• Drive continuous improvement of application security, technical quality, and engineering practices

Requirements

• 3+ years of commercial software development experience with Java
• Expert-level knowledge of Java, with the capability to explain advanced concepts in depth, reason through complex coding and design challenges, and consistently deliver high-quality, maintainable solutions
• 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
• Practical experience with Kafka or similar event-driven messaging technologies, including producers/consumers, asynchronous communication patterns, and the design of reliable event-driven flows
• Proven background in mentoring engineers, leading technical initiatives, and collaborating with stakeholders
• Proficiency in English at an Upper-Intermediate level (B2) or higher

Nice to have

• Familiarity with PostgreSQL
• Understanding of common application vulnerabilities, secure coding practices, dependency-related risks, and approaches for identifying and remediating security findings

We offer

• International projects with top brands
• Work with global teams of highly skilled, diverse peers
