Familiarity with version control systems like Git, basic knowledge of RESTful APIs, and exposure to development tools such as npm or Yarn are typically expected. Strong problem-solving abilities, attention to detail, and effective communication help you collaborate well within a team and adapt to feedback. These skills are crucial for building responsive user interfaces, maintaining code quality, and contributing effectively to dynamic development projects.

What types of projects and tasks can a Trainee React Frontend Developer expect to work on during their first six months?

As a Trainee React Frontend Developer, you will typically start with smaller tasks such as fixing bugs, writing unit tests, and implementing simple UI components under the guidance of senior developers. You'll gradually progress to working on larger features, integrating APIs, and collaborating with designers to ensure user interfaces are both functional and visually appealing. Regular code reviews and pair programming sessions are common, providing valuable feedback and learning opportunities. This phase is crucial for building a strong foundation in React and understanding best practices in frontend development.

Their responsibilities typically include assisting in the development of new features, fixing bugs, and learning how to use development tools and workflows.

Job description

Description
About Xe
Xe is a cross-border payments platform. We help SMEs and consumers in the US, UK, Canada, Australia, and New Zealand collect, convert, hold, and send money across markets. Each year, over 300 million people use Xe for currency information and over 350,000 use us to send money overseas.
Today, we're rebuilding the platform layer behind cross-border payments for corporate and consumer clients. We're small enough that your code ships fast and your decisions matter, and Euronet Worldwide (Nasdaq: EEFT) backs us so the problems stay real-scale.
About This Role
We're looking for a senior 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 sense of clean architecture, and a collaborative mindset. Beyond writing high-quality code, you'll mentor other developers, drive technical direction, and work closely with designers and stakeholders to deliver intuitive, polished interfaces. This is a hands-on role for someone with at least five years of experience who takes ownership of code quality and enjoys raising the bar for the whole team.
If you're proficient in Vue 3+, that's ideal, but we're equally interested in strong React or Angular engineers who are excited to make the switch. Experience in payments, FX, or other regulated industries is a plus.
What You'll Do
  • Build and maintain high-quality, maintainable frontend applications using Vue 3+ and TypeScript.
  • Architect scalable frontend solutions with clean code practices.
  • Conduct thorough code reviews and uphold high standards for code quality across the team.
  • Mentor fellow developers on best practices, architecture, and clean coding habits.
  • Style and build responsive, accessible interfaces using modern Tailwind CSS, HTML5, and CSS3.
  • Write and maintain unit & integration tests with Vitest.
  • Work with modern build tooling and bundlers such as Vite.
  • Collaborate closely with designers to translate UX/UI concepts into visually appealing, intuitive experiences.
  • Partner with engineers and stakeholders in an Agile/Scrum environment, contributing to and helping guide the team's technical decisions.
  • Leverage AI coding tools such as Claude Code or Copilot to work more effectively.
  • Communicate clearly in writing and verbally, helping align both engineers and non-technical stakeholders.
What We're Looking For
Must-have
  • 5+ years building production software.
  • Proficiency in Vue (3+), or strong experience in other major frontend frameworks (React, Angular) with the desire to switch to Vue.
  • Strong knowledge of TypeScript.
  • Strong clean code habits.
  • Strong architectural knowledge of frontend architecture and OOP/OOD.
  • Strong code review skills.
  • Experience mentoring other developers regarding best practices and code quality.
  • Experience with modern Tailwind CSS.
  • Experience with writing unit tests using Vitest or Jest.
  • Understanding JavaScript build tools and module bundlers like Vite/Rollup/Webpack.
  • Strong understanding of HTML5, CSS3, and responsive web design principles.
  • Understanding of UX/UI design principles and the ability to collaborate closely with designers to create visually appealing and intuitive interfaces.
  • Familiarity with Agile/Scrum methodologies and effective collaboration with other developers and stakeholders.
  • Experience or open mindset for using AI coding tools like Claude Code, Copilot etc.
  • Strong written and verbal communication, including the ability to align engineers and stakeholders around a technical direction.

Nice-to-have
  • Experience with PostCSS/SASS/SCSS or similar CSS technologies for styling and optimizing UI components.
  • Knowledge of e2e testing frameworks such as Playwright.
  • Experience with Storybook for component-driven development and UI documentation.
  • Payments, FX, or regulated-industry experience.
Perks & Benefits
  • Medical, Dental & Vision Insurance
  • 401K Plan with Match
  • Employee Stock Purchase Plan
  • Paid Vacation / Sick Leave
  • Hybrid Work Schedule
  • Tuition Assistance
  • Growth Opportunities
  • Corporate gatherings & team bonding events
  • Plumm Mental Health and Wellbeing
  • Volunteering day for a charity of your choice
