Senior Software Engineer II (Full Stack)

Shutterfly is hiring a Senior Software Engineer II (Full Stack) to build and maintain high-performance web applications, with a primary focus on interactive frontend systems and contributions to backend services. The role owns features end-to-end, supports architecture and performance decisions, and collaborates across product and engineering teams.

Responsibilities:

• Develop and maintain scalable, high-performance web applications across the full stack using React, TypeScript, JavaScript, HTML5, CSS3, GraphQL, Java, Spring Boot, and Python
• Build rich, interactive user experiences, including canvas-based rendering and custom UI workflows for personalized product creation (e.g., photo books, SVG layouts)
• Own frontend features end-to-end — from technical design through implementation, testing, deployment, and post-launch support
• Design, develop, and maintain backend services, domain services, and RESTful/GraphQL APIs that support frontend capabilities
• Optimize frontend performance across rendering, memory usage, network efficiency, and bundle size
• Contribute to architecture decisions spanning state management, data-fetching strategies, SSR/CSR tradeoffs, and API design
• Apply Test-Driven Development (TDD) practices using Jest and modern component/integration testing frameworks
• Ensure applications meet accessibility (WCAG), security, and privacy compliance standards
• Collaborate closely with designers, backend engineers, and product stakeholders to deliver cohesive user experiences
• Participate actively in code reviews, raising quality, consistency, and maintainability across the codebase
• Deploy and operate services in AWS-based environments, working with CI/CD pipelines
• Leverage AI-assisted development tools where appropriate to improve developer productivity and software quality

Requirements:

• Bachelor's degree in Computer Science or a related field
• 7+ years of professional software engineering experience with a primary focus on frontend development and meaningful backend experience
• Expertise in React, TypeScript, JavaScript (ES6+), HTML5, CSS3, and GraphQL
• Working knowledge in Java, Spring Boot, Python or similar technologies for backend development
• Comprehensive understanding of frontend architecture, single-page application (SPA) design, and modern rendering patterns
• Hands-on experience with canvas rendering, custom UI engines, or performance-critical frontend components
• Strong computer science foundation, including data structures, algorithms, and performance analysis
• Experience designing and integrating with RESTful and GraphQL APIs
• Proven track record in Test-Driven Development and automated testing using tools like Jest
• Familiarity with cloud-based deployments, especially AWS
• Excellent problem-solving skills and ability to work independently with minimal supervision
• Demonstrated success in building maintainable, scalable, and cost-effective solutions across the stack
• Adaptable to evolving product requirements and technical constraints while balancing user experience, engineering excellence, and long-term maintainability
• A mindset of continuous improvement — bringing forward ideas that promote modern engineering standards, tooling, and best practices
• Experience with AI-assisted development tools such as Claude Code, GitHub Copilot, or similar
• Experience working with LLMs (Large Language Models) and generative AI applications, including prompt engineering and fine-tuning strategies
• Experience building frontend build, deployment, and CI/CD workflows
• Experience with message brokers such as RabbitMQ
• Experience with workflow engines
• Experience with infrastructure-as-code tools such as Terraform
