What is a frontend developer engineer?

Frontend Developer Engineers are professionals who design, build, and maintain the user interface and user experience of websites or web applications. They use technologies like HTML, CSS, and JavaScript to create responsive and interactive designs that work across different devices and browsers. Their role often involves collaborating with designers and backend developers to ensure seamless integration of visual elements and server-side logic. Frontend Developer Engineers also optimize web performance and accessibility to provide the best possible experience for users.

How do frontend developer engineers typically collaborate with designers and backend developers during a project?

Frontend Developer Engineers work closely with UX/UI designers to translate design mockups into interactive web interfaces, ensuring fidelity to the intended user experience. They also coordinate regularly with backend developers to integrate APIs and ensure seamless data flow between the client side and server side. Effective communication, participation in agile ceremonies, and using collaboration tools like Git, Jira, or Figma are essential for aligning on project requirements, managing dependencies, and resolving issues quickly.

What are the key skills and qualifications needed to thrive as a frontend developer engineer, and why are they important?

To thrive as a Frontend Developer Engineer, you need proficiency in HTML, CSS, JavaScript, and a solid understanding of responsive design, typically supported by a degree in computer science or a related field. Experience with frameworks like React, Angular, or Vue.js, as well as familiarity with version control systems such as Git, are commonly required technical skills. Strong problem-solving abilities, attention to detail, and effective communication help you collaborate with designers and back-end engineers. These skills are essential to create user-friendly, high-performance web applications that meet both technical and business requirements.

About the Role
We're looking for a Principal Frontend Engineer to help build and shape the user-facing side of our products. You'll bring deep expertise in modern frontend development, a strong understanding of clean architecture, and a collaborative mindset.
In addition to writing high-quality code, you'll mentor other developers, help guide technical direction, and work closely with designers and stakeholders to deliver intuitive, polished interfaces. This is a hands-on position for someone with at least five years of experience who takes ownership of code quality and enjoys raising standards across the team.
Experience with Vue 3+ is preferred, but we're also interested in strong React or Angular engineers who are excited to transition to Vue. Experience in payments, foreign exchange, or another regulated industry is a plus.

What You'll Do
  • Build and maintain reliable, maintainable frontend applications using Vue 3+ and TypeScript.
  • Design scalable frontend solutions using clean architecture and coding practices.
  • Conduct thorough code reviews and uphold high standards for quality across the team.
  • Mentor other developers on architecture, best practices, and clean coding habits.
  • Build responsive and accessible interfaces using Tailwind CSS, HTML5, and CSS3.
  • Write and maintain unit and integration tests using Vitest.
  • Work with modern build tools and bundlers such as Vite.
  • Collaborate with designers to turn UX/UI concepts into intuitive and visually polished experiences.
  • Partner with engineers and stakeholders in an Agile/Scrum environment while contributing to the team's technical direction.
  • Use AI development tools such as Claude Code or GitHub Copilot to improve productivity.
  • Communicate clearly with both technical and non-technical stakeholders.

Required Qualifications
  • Five or more years of experience building production software.
  • Proficiency with Vue 3+, or strong experience with React or Angular and an interest in transitioning to Vue.
  • Strong TypeScript knowledge.
  • A demonstrated commitment to clean, maintainable code.
  • Strong knowledge of frontend architecture and object-oriented programming and design.
  • Experience conducting effective code reviews.
  • Experience mentoring developers on best practices and code quality.
  • Experience with modern Tailwind CSS.
  • Experience writing unit tests using Vitest or Jest.
  • Understanding of JavaScript build tools and module bundlers such as Vite, Rollup, or Webpack.
  • Strong knowledge of HTML5, CSS3, responsive web design, and accessibility principles.
  • Understanding of UX/UI design principles and the ability to collaborate closely with designers.
  • Familiarity with Agile/Scrum methodologies and cross-functional collaboration.
  • Experience with—or an open mindset toward—AI coding tools such as Claude Code and GitHub Copilot.
  • Strong written and verbal communication skills, including the ability to align engineers and stakeholders around a technical direction.

Preferred Qualifications
  • Experience with PostCSS, Sass, SCSS, or similar CSS technologies.
  • Knowledge of end-to-end testing frameworks such as Playwright.
  • Experience with Storybook for component-driven development and UI documentation.
  • Experience in payments, foreign exchange, or another regulated industry.

Perks and Benefits
  • Medical, dental, and vision insurance
  • 401(k) plan with company match
  • Employee stock purchase plan
  • Paid vacation and sick leave
  • Hybrid work schedule
  • Tuition assistance
  • Professional growth opportunities
  • Company gatherings and team-building events
