We are seeking an experienced Senior Developer to join our Digital Technology team within a large, enterprise-scale organization. This role is responsible for the development, enhancement, and support of several enterprise JS applications deployed across our plant and transportations networks.

The applications currently run on iPads and iPhones and are both critical to daily operations.

• Take end-to-end- ownership of assigned application areas, including design, development, testing, deployment, and, when required, production support
• Proactively identify system improvements, technical debt, and operational risks rather than working solely from a ticket backlog
• Collaborate with product owners, business analysts, UX designers, and other engineers to translate business needs into scalable technical solutions
• Ensure the application performs reliably on iPad/iPhone devices in plant, warehouse, and delivery environments
• Participate actively in Agile ceremonies, including sprint planning, daily stand-ups, reviews, and retrospectives
• Provide mentoring and technical leadership to other developers and contribute to coding standards and architectural decisions
• Troubleshoot and resolve production issues, ensuring minimal disruption to plant and transportation operations
• Ensure solutions align with enterprise security, scalability, and operational standards

Required Qualifications

• Strong hands-on- experience with front end frameworks; Nuxt, Vue, Svelte, etc.
• Working familiarity with Docker, Git, and AWS in an enterprise application environment
• Prior experience leveraging Firestore or other real time databases.
• Proven experience developing and supporting production-grade, enterprise applications
• Prior experience working in an Agile/Scrum environment
• Demonstrated ability to work independently while collaborating effectively within a cross functional- team
• Strong sense of ownership, accountability, and problem-solving- capability
• Excellent communication skills, with the ability to engage both technical and non-technical stakeholders
• Experience leveraging testing tools such as Vitest, Playwright, and Jest for application testing
• Proficient with AI-assisted development tools for code generation and analysis, with strong emphasis on human review, validation, and technical ownership

Preferred Qualifications

• Prior practical experience with the Vue.js and Nuxt frameworks
• Experience developing hybrid applications (e.g. Capacitor) for tablet or mobile (iPad/iOS) environments
• Experience working in large, distributed enterprise environments
• Exposure to CI/CD pipelines and cloud-based- deployment models
• Experience with Angular a plus (primary framework is Nuxt)
