Sr Fullstack Developer

Full Stack Java Software Developer, Expert, CGI is seeking an experienced Full Stack Java Software Developer at the Expert level to provide technical leadership in the design, development, modernization, and delivery of complex enterprise applications.

This is a hands on engineering role for someone who can move comfortably between architecture and implementation. The ideal candidate brings deep Java and full stack expertise, makes sound technical decisions in ambiguous environments, and helps engineering teams solve difficult problems while improving the quality, reliability, security, and maintainability of the systems they build.

The scope of this role extends beyond an individual team. Expert engineers influence architecture and engineering practices across multiple systems or teams, solve highly complex technical problems, establish reusable patterns and standards, and serve as technical authorities within their area of expertise.

This role is ideal for an engineer who enjoys building software as much as leading technical direction.

Your future duties and responsibilities

. Design, develop, test, deploy, and support scalable, secure, and maintainable full stack applications.

. Serve as a hands on technical leader, contributing production quality code while guiding technical implementation.

. Design and build backend applications and services using Java, Spring, and Spring Boot.

. Develop modern web applications using technologies such as React, Angular, TypeScript, JavaScript, HTML, and CSS, depending on the application stack.

. Design and integrate RESTful APIs, services, and event driven or asynchronous components.

. Provide technical leadership throughout the software development lifecycle, from requirements and architecture through implementation, testing, deployment, and production support.

. Translate complex business and technical requirements into practical, maintainable software solutions.

. Lead technical design discussions and make architectural decisions involving application structure, APIs, integration patterns, data models, security, performance, scalability, and resiliency.

. Evaluate trade offs between competing approaches and clearly communicate technical recommendations to engineering and non engineering stakeholders.

. Perform code and design reviews and establish expectations for code quality, automated testing, observability, maintainability, and secure development.

. Diagnose and resolve complex production issues spanning application, integration, database, infrastructure, and distributed system boundaries.

. Improve application performance, availability, resilience, monitoring, and operational supportability.

. Identify and reduce technical debt while balancing modernization efforts against business delivery priorities.

. Design and implement solutions using relational and/or NoSQL data stores and sound data access patterns.

. Apply CI/CD, DevOps, automated testing, source control, and infrastructure or cloud native development practices to improve delivery quality and repeatability.

. Incorporate security throughout application design and development, including authentication, authorization, secrets management, dependency management, data protection, and secure coding practices.

. Mentor software engineers through design discussions, pairing, code reviews, troubleshooting, and knowledge sharing.

. Collaborate closely with Product Owners, Scrum Masters, architecture, security, infrastructure, operations, QA, and other engineering teams.

. Lead technical discovery and proof of concept efforts for new technologies or architectural approaches.

. Develop reusable frameworks, libraries, reference implementations, development standards, and engineering best practices.

. Provide technical direction across multiple applications or engineering teams and influence broader technology strategy and architectural standards.

Significant professional software development experience, with advanced expertise designing and building enterprise applications using Java.

. Strong experience with the Spring Framework and Spring Boot.

. Strong full stack development experience, including modern web development technologies such as React or Angular and JavaScript/TypeScript.

. Experience designing, developing, integrating, and supporting REST APIs and distributed services.

. Experience performing technical design and code reviews.

. Demonstrated ability to lead technical initiatives and mentor other software engineers.

. Ability to communicate complex technical concepts, alternatives, risks, and trade offs to technical and non technical audiences.

. Ability to work effectively in an Agile/Scrum software development environment.

. Demonstrated ability to influence technical direction, architecture, and engineering practices across multiple applications or teams.

Preferred Qualifications

. Experience designing and operating microservices and distributed systems.

. Experience with cloud platforms such as AWS, Microsoft Azure, or Google Cloud Platform.

. Experience with Docker, Kubernetes, or other containerization and orchestration technologies.

. Experience with messaging or event streaming technologies such as Apache Kafka.

. Experience with observability platforms and practices involving application logging, metrics, tracing, and production monitoring.

. Experience implementing resiliency patterns such as retries, timeouts, circuit breakers, caching, and graceful degradation.

. Experience with API management, OAuth/OIDC, identity integration, and service to service security.

. Experience modernizing legacy or monolithic applications.
