What is a Sr Frontend Developer?

Sr Frontend Developers are experienced software engineers who specialize in building and optimizing the user interfaces of web applications. They are responsible for translating design mockups into interactive, responsive, and accessible web pages using technologies like HTML, CSS, and JavaScript frameworks (such as React, Angular, or Vue). In addition to coding, Sr Frontend Developers often lead technical decisions, mentor junior developers, and collaborate closely with designers and backend engineers to deliver high-quality user experiences. Their expertise ensures that web applications are visually appealing, performant, and user-friendly.

What are the key skills and qualifications needed to thrive as a Sr Frontend Developer?

To thrive as a Sr Frontend Developer, you need deep expertise in HTML, CSS, JavaScript, and modern front-end frameworks like React or Angular, usually backed by a degree in computer science or equivalent experience. Advanced knowledge of tools such as Git, Webpack, RESTful APIs, and proficiency with testing frameworks is typically required. Outstanding problem-solving abilities, strong collaboration, and effective communication set top performers apart in this role. These skills ensure the delivery of high-quality, user-friendly interfaces and seamless teamwork in fast-paced development environments.

What are some common challenges faced by Sr Frontend Developers when working on cross-functional teams?

Sr Frontend Developers often collaborate closely with backend engineers, UX/UI designers, and product managers. A common challenge in these environments is ensuring clear communication of technical requirements and design expectations to avoid misunderstandings that can lead to rework. Balancing user experience with technical feasibility is another frequent hurdle, especially when negotiating priorities between design vision and performance constraints. Effective Sr Frontend Developers proactively bridge gaps through strong documentation, regular alignment meetings, and by advocating for best practices in both development and design.

Job description

Senior Frontend Developer


We're looking for a Senior Frontend Developer to build and scale the customer-facing experience across our direct-to-consumer eCommerce and subscription platform at Whisky Library. This role is responsible for delivering fast, intuitive, and high-quality web experiences that help customers discover, learn about, and purchase whiskey online.
You'll work closely with product, design, marketing, and backend engineering to transform ideas into polished, production-ready features. We're looking for someone who thrives in a fast-paced, high-ownership environment, enjoys solving complex technical challenges, and takes pride in building products that customers love.
Who We Are
We are Whisky Library, a U.S.-based whiskey retail and subscription company building a modern way to discover and purchase bourbon.
The whiskey industry has remained largely unchanged for decades, and our mission is to create a better online experience for whiskey enthusiasts from first-time buyers to seasoned collectors. Our platform combines premium whiskey retail with a curated subscription experience, helping customers discover new bottles while learning more about the craft behind them.
We're a small, globally distributed team that values ownership, speed, and execution. We believe great ideas can come from anyone, and every team member is empowered to make meaningful contributions. We care deeply about quality, continuous improvement, and building products that make a measurable impact on both our customers and the business.
What You'll Do
Frontend Development

  • Build modern, responsive, and high-performance web applications using React and Next.js

  • Develop customer-facing features across our eCommerce store, subscription platform, customer portal, and internal tools

  • Translate Figma designs into clean, reusable, and maintainable code

  • Ensure a consistent experience across desktop, tablet, and mobile devices

  • Optimize page performance, Core Web Vitals, and overall frontend architecture

Product Development

  • Collaborate with product managers and designers to build intuitive customer experiences

  • Work closely with backend engineers to integrate APIs and third-party services

  • Participate in feature planning, technical discussions, and architecture decisions

  • Continuously improve application usability, accessibility, and performance

Code Quality & Engineering Excellence

  • Write clean, scalable, and well-tested code following modern engineering best practices

  • Review pull requests and contribute to maintaining high development standards

  • Refactor and improve existing codebases for maintainability and performance

  • Identify and resolve bugs before they impact customers

Collaboration & Ownership

  • Work cross-functionally with design, marketing, operations, and engineering teams

  • Take ownership of projects from planning through deployment

  • Proactively identify technical improvements and opportunities to improve customer experience

  • Contribute ideas that help improve development workflows and engineering processes


What We're Looking For
Required Qualifications

  • 4+ years of professional frontend development experience

  • Strong experience with React.js and Next.js

  • Excellent knowledge of TypeScript, JavaScript (ES6+), HTML5, and CSS3

  • Experience with modern styling frameworks such as Tailwind CSS

  • Experience consuming REST APIs and working with asynchronous data

  • Strong understanding of responsive design and cross-browser compatibility

  • Experience using Git in collaborative development environments

  • Excellent problem-solving skills and attention to detail

  • Strong communication skills and ability to work independently in a remote environment

Preferred Qualifications

  • Experience with Shopify or Shopify Hydrogen

  • Experience building eCommerce or subscription-based applications

  • Familiarity with GraphQL

  • Experience with state management libraries such as Zustand or Redux

  • Understanding of performance optimization and Core Web Vitals

  • Experience with testing frameworks such as Jest, Playwright, or Cypress

  • Familiarity with Vercel deployment workflows and modern CI/CD pipelines


Success in This Role
You'll be successful if you:

  • Take full ownership of the features you build from development through deployment

  • Deliver high-quality code without sacrificing speed

  • Think beyond implementation and consider the overall customer experience

  • Proactively identify problems and propose scalable solutions

  • Collaborate effectively across engineering, design, and business teams

  • Continuously improve both the product and the engineering processes


Why Join Us?

  • Help build a category-defining DTC whiskey brand in a rapidly evolving industry

  • Work on meaningful products used by thousands of customers

  • High-impact role with direct influence on product direction and customer experience

  • Small, highly collaborative team where your work is immediately visible

  • Opportunity to own major features and contribute to technical architecture

  • Remote-first culture with significant autonomy and trust

  • Competitive compensation and opportunities for long-term growth
