Even if you do not check every box below, apply anyway. EY is a place for career growth and everyone's starting point is different. We would love to hear your story.

The opportunity

As a Full Stack Developer Senior, you will independently develop, test, and maintain high‑quality software solutions across the technology stack. You will work closely with multidisciplinary teams to deliver scalable, secure, and production‑ready applications that are increasingly shaped by intelligent, data‑driven capabilities.

In this role, engineers are expected to approach problem‑solving with a modern mindset, considering how automation, AI‑assisted workflows, and intelligent features can improve system design, developer productivity, and user experience. You will help shape solutions where AI is treated as a core design consideration rather than an afterthought, while maintaining strong software engineering fundamentals.

The role values adaptability across programming languages and platforms, comfort working across frontend and backend systems, and the ability to apply sound engineering judgment in evolving technical landscapes. You will take ownership of your work, contribute to system design decisions, and support solutions from inception through launch and ongoing evolution.

At EY, we partner with the world's leading organizations to adopt emerging technologies responsibly and effectively. We believe in transforming how companies operate by asking better questions, applying engineering rigor, and delivering trusted, intelligent solutions that scale.

Your key responsibilities

As a Senior in Application Design and Development, you will lead the effective management and delivery of processes, solutions, and projects, ensuring a strong focus on quality and risk management. This role presents exciting challenges and opportunities for growth, allowing you to apply your expertise in guiding others and recommending quality solutions. You will engage regularly with external clients, actively participating in working sessions and leading workstreams from planning through execution and closure. Travel may be required as needed by external clients.

• Develop solutions to complex problems, recommending changes to policies and establishing procedures that impact your work area.
• Exercise judgment in selecting methods, techniques, and evaluation criteria for obtaining results.
• Provide direction and feedback to team members, ensuring successful task completion.

Skills and attributes for success

To thrive in this role, you will need a blend of technical and business skills that will make a significant impact. Your ability to build and manage relationships, communicate effectively, and lead teams will be essential.

• Design, develop, test, and deploy a custom enterprise application using React frontend and Java/Spring Boot backend

• Build and maintain backend services and APIs using modern backend programming languages such as Java, Python, Go, or JavaScript or TypeScript, across technology ecosystems including Node.js, Spring, and .NET
• Contribute to building and shipping intelligent application features, including integrations with large language models, predictive capabilities, and agent‑driven workflows
• Collaborate with cross functional teams to refine requirements and translate them into technical designs and functional code
• Contribute to system and application architecture, including data models, integrations, security, and cloud deployment considerations
• Participate fully in agile delivery, including sprint planning, refinement, reviews, demos, and retrospectives
• Conduct code reviews and help establish high standards for code quality, testing, and maintainability
• Create and maintain technical documentation aligned with best practices across the software development lifecycle
• Identify, troubleshoot, and resolve issues across development and production environments
• Mentor junior engineers and contribute to a collaborative, high performing engineering culture
• See projects through from inception to launch and continued evolution in partnership with EY and client leadership

To qualify for the role, you must have

• Bachelor's degree in computer science, Software Engineering, or related field
• 5 or more years of professional software engineering experience
• Must have experience with full stack development with required experience in React frontend development (e.g., components, hooks, data & state management, API integrations) and Java/Spring Boot backend development
• Experience with other frontend programming languages - JavaScript, TypeScript, CSS
• Experience designing and implementing RESTful APIs with thorough understanding of Microservices based architecture and core design patterns
• Experience with building modular, scalable services, integrations and event-driven architecture (e.g, Kafka, other messaging systems)
• Experience with Test-Driven Development experience is a must
• Strong database skills across both relational and non‑relational data stores, including query optimization, data model and schema design
• Experience using Git‑based version control and collaborative development workflows
• Comfort working in local and cloud environments, including command‑line tooling and system configuration
• Ability to independently identify, debug, and resolve issues
• Strong written and verbal communication skills
• Willingness and ability to travel based on client needs, up to approximately 25 percent

Ideally, you'll also have

• Experience building and operating cloud‑native or microservices‑based applications, preferably on Azure or similar cloud platforms
• Hands‑on exposure to cloud services for compute, data, identity, and monitoring
• Familiarity with service‑oriented, API‑driven, and distributed system architectures
• Experience with containerization and orchestration technologies such as Docker and Kubernetes
• Comfort designing systems where AI‑driven capabilities are considered early, with an understanding of when AI is appropriate versus traditional deterministic logic
• Experience with AI‑assisted developer tools like Cursor, Replit or GitHub Copilot, agent‑based patterns, or orchestration approaches
• Understanding of security, identity, and access management in cloud environments
• Familiarity with CI/CD pipelines, version control tools (Bitbucket, GitHub, JIRA), DevOps practices, and production observability
• Experience supporting applications post‑launch in enterprise or regulated environments
