Title:  Front-End/UI Developer
Job Type:  Full-time / Permanent
Target Start Date: ASAP
Work Location/Structure:  One of our client's offices in Boston, New York, Los Angeles, or San Francisco)

About the Opportunity:

Our client, a leader in Strategy Consulting, is looking for a skilled  Front-End/UI Developer  to join their team for a permanent role. The firm is expanding its capabilities and is seeking a hybrid design and engineering expert to create and build engaging, client-facing tools. This brand-new, high-impact position is designed to fill a critical gap—the need for strong visual design and interaction expertise to complement their existing backend and data teams. This role requires a self-motivated professional who can blend design, prototyping, and implementation to deliver superior user experiences quickly.

Key Responsibilities & Deliverables:

This role is focused on the successful completion of specific tasks and deliverables. Your responsibilities will include:
  • Design & Prototyping:  Paper prototyping, creating click-through demos, building end-to-end Figma app walkthroughs, and developing component/asset libraries.
  • Visual Storytelling:  Developing visual communication for analytics, charts, and maps, and communicating design and technical solutions to both technical and non-technical teams.
  • Front-End Development:  Implementing production-ready designs using JavaScript/TypeScript and modern frameworks, with a preference for React or Svelte.
  • Deployment & Integration:  Deploying applications to platforms like Vercel or Netlify, understanding backend constraints (APIs, Parquet files, S3), and migrating Python-based dashboards (e.g., Matplotlib) into proper web tools.
  • AI Workflow Layer:  Building applications on top of LLMs to create agentic workflows for clients, such as matching products to customers and generating personalized offers (Note: this is an application building role, not an LLM development role).
Required Skills & Experience:

We are looking for someone with a proven track record of successful engagements. The ideal candidate will have:
  • Hybrid Skill Set:  A strong design and engineering hybrid skill set with a proven UI/UX portfolio and strong visual communication skills of 5+ years
  • Technical Expertise:  Proficiency in JavaScript/TypeScript and modern front-end frameworks (React is preferred, or Angular, Vue).
  • Design & Prototyping:  Strong grasp of UI/UX principles, with proficiency in modern design and prototyping tools including Figma.
  • Deployment & Backend Knowledge:  Deployment experience (Vercel, Netlify, AWS), understanding of RESTful APIs, Node.js, and server-side development (e.g., Express, Java, or Python), and familiarity with version control (Git) and CI/CD pipelines.
  • Data Visualization:  Familiarity with data visualization libraries like D3, Recharts, or dashboarding tools.
  • Soft Skills:  A mix of creativity, technical depth, and a collaborative mindset, with a passion for clean design, intuitive user experiences, and scalable architecture.
  • Preferred Experience:  Experience at design tool companies (e.g., Figma), small digital agencies, or consulting innovation labs (e.g., Deloitte Digital, BCG DV).
