Senior Full Stack Software Engineer (Onsite- MA)

We are hiring a Full Stack Software Engineer (onsite in MA) to help build and evolve a next-generation digital platform supporting a portfolio of internal and customer-facing products. As an individual contributor, you will play a pivotal role in engineering both the back-end data infrastructure and front-end UI architecture, working collaboratively across UX, Product, and Data teams to launch high-performance, AI-augmented experiences while helping transition systems from external development partners to internal ownership.

This role is ideal for a technologist who thrives in 0-to-1 environments, understands complex enterprise systems, and is passionate about creating scalable architecture that supports multiple applications across a growing digital ecosystem.

• Design, develop, and maintain full-stack solutions across front-end, middleware, back-end, and data layers.
• Build new UI experiences from scratch in collaboration with UX/UI designers and product managers.
• Collaborate with UX to operationalize a cross-product design system, including component libraries, design tokens, documentation, and Storybook implementations.
• Collaborate on data modeling, APIs, and visualization components; ensure clean integration of AI/ML-powered features and tools.
• Optimize application performance and participate in architectural decisions to ensure scalability, reliability, and security.
• Implement A/B testing infrastructure, personalization capabilities, and analytics instrumentation.
• Participate in sprint planning, code reviews, and documentation with QA and Engineering team support.
• Collaborate across global teams in the U.S., EMEA, and APAC on multi-property, platform-wide initiatives.
• Partner with external engineering vendors during the transition period and assume long-term ownership of internal codebases and platform architecture.
• Develop headless commerce experiences integrating Shopify storefront APIs with internal enterprise systems.
• Integrate front-end applications with enterprise platforms, headless eCommerce services, and internal data systems.

• 5+ years of full stack software development experience, ideally in enterprise SaaS or B2B platforms.
• Proficiency in multiple front-end frameworks (e.g., React, Angular, Vue) and UI tooling (e.g., Tailwind, Material UI).
• Strong back-end experience with Node.js, Python, or Java, including API and data model design.
• Experience working with modern CI/CD pipelines, Git, Docker, and cloud platforms (AWS/Azure/GCP).
• Proven ability to build front-end applications that are performant, accessible (WCAG/ARIA), and scalable.
• Familiarity with integrating generative AI features or data-driven UIs (e.g., GPT, Lang Chain, or similar frameworks).
• Deep understanding of component architecture, modular design, and systems optimization.
• Experience with data visualization frameworks (e.g., D3.js, Plotly, Highcharts).
• Ability to work cross-functionally with UX, Data Science, QA, and Product teams.

• Experience building or maintaining a design system or component library.
• Familiarity with personalization tools, experimentation frameworks, or A/B testing tools.
• Experience developing or integrating headless commerce solutions (e.g., Shopify storefront APIs or similar platforms).
• Experience working in highly regulated or technical environments (e.g., Life Sciences, IoT, B2B2C).
• Previous experience contributing to or leading platform modernization efforts.
• Experience with mobile-first or responsive design patterns.
• Experience with working within an agile scrum team as a software developer.
