Principal Full Stack Software Engineer

About the Role

We are looking for a Principal Full Stack Software Engineer to lead the modernization of one of our key enterprise applications. This role is highly hands-on, technically demanding, and ideal for an engineer who excels at building scalable, user-centered platforms while lifting the technical bar across the organization. As a Principal Engineer, you will steer the technical direction of a multi-million-user application as it transitions from a legacy JSP-based experience to a modern, responsive React Native application that also renders seamlessly on the web through our standardized container architecture. You will collaborate across product, engineering, design, and backend teams to deliver a production-ready solution within 6 months. This is a role for a builder, an architect, a mentor, and a trusted technical partner.

What You’ll Do

1. Lead the Full-Stack Architecture & Execution

• Own end-to-end technical delivery of a cross-platform React Native application rendered on mobile and web through a shared container system.
• Make strategic decisions balancing scalability, performance, user experience, security, and long-term maintainability.
• Write high-quality, production-grade code as the technical role model for the team.

2. Adopt and Advance the Company’s Container Strategy

• Implement the standardized container platform to deploy web and mobile experiences consistently.
• Act as a trusted partner to evolve container framework capabilities, improve developer experience, and ensure best-practice adoption across feature teams.

3. Lead Migration from Legacy JSP to Modern React Native/Web UI

• Drive the structured migration of legacy JSP screens into modular, component-based React Native code.
• Ensure parity with existing business logic while improving usability, accessibility, and performance.
• Define migration sequencing, risk mitigation, and rollout strategy.

4. Establish Development Best Practices & Automation

• Introduce modern engineering standards including automated testing, coding guidelines, CI/CD pipelines, linting, and observability.
• Guarantee high-quality through unit testing, integration testing, and UI automation.
• Mentor and uplift engineers through code reviews, architecture sessions, and hands-on pairing.

5. Integrate GenAI/AI Capabilities Thoughtfully

• Identify meaningful opportunities to inject GenAI into the product experience (e.g., intelligent suggestions, autofill, contextual support).
• Leverage GenAI frameworks to enhance developer productivity, improve testing, or streamline workflow automation.
• Partner with ML/AI teams to integrate AI services safely and responsibly.

6. Collaborate End-to-End Across the Organization

• Work closely with backend teams to design GraphQL schemas, APIs, and access patterns.
• Partner with product and UX teams to define a cohesive user experience.
• Ensure alignment with cross-functional stakeholders to deliver a reliable, secure, and scalable solution.

7. Deliver a Production-Ready MVP in Six Months

• Own key milestones and drive execution across engineering teams to ensure an on-time, high-quality launch.
• Champion operational readiness, performance validation, accessibility, and end-to-end integration with backend services.

What You’ll Bring

Required Qualifications
