Contract React Frontend Developer information

How does a contract React frontend developer typically collaborate with design and backend teams during a project?

As a Contract React Frontend Developer, you’ll frequently work alongside UI/UX designers to translate visual concepts into interactive features, ensuring that designs are both functional and visually consistent. You'll also coordinate with backend developers to integrate APIs and align on data structures, which often involves regular stand-ups or sprint meetings. Effective communication and familiarity with collaborative tools (like Jira, Figma, or Git) are essential to keep everyone aligned, especially since contract roles may require ramping up quickly on existing team workflows.

What is a contract React frontend developer?

A Contract React Frontend Developer is a software professional hired on a temporary or project basis to build and maintain user interfaces using the React JavaScript library. They focus on translating design mockups and requirements into interactive, responsive web applications. Unlike full-time employees, contract developers typically work for specific durations or on particular projects, often bringing specialized expertise to help teams meet their goals efficiently. Companies hire contract React developers to scale up their frontend development efforts or to introduce advanced capabilities without long-term commitments.

What are the key skills and qualifications needed to thrive as a contract React frontend developer?

To thrive as a Contract React Frontend Developer, you need a solid understanding of JavaScript, React.js, HTML, CSS, and experience with responsive web design, often supported by a relevant computer science degree or proven portfolio. Familiarity with tools like Redux, Git, RESTful APIs, and testing frameworks (e.g., Jest or Cypress) is typically required, and certifications in modern JavaScript frameworks can be advantageous. Strong problem-solving, adaptability, and clear communication skills help you collaborate effectively with teams and clients in dynamic contract environments. These skills and qualities ensure you can deliver high-quality, maintainable code efficiently while meeting client needs and adapting to changing project requirements.

KORE1, a nationwide provider of staffing and recruiting solutions, has an immediate opening for a Principal Frontend Engineer based in Denver, Co. The role is Hybrid with 3 days onsite each week. 

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
  • Mental health and well-being support through Plumm
  • One paid volunteer day for a charity of your choice



Compensation depends on experience but is typically 110-165k DOE
