Job Description

We’re looking for a senior front-end engineer to help accelerate client onboarding by designing and documenting custom web forms using our platform. This is a contractor role focused on shipping polished, production-ready UI—not meetings or long-running feature work. The work is outcome-driven: if you do the job well, the effective rate lands at or above the stated target.

Requirements

• Senior-level experience with CSS, HTML, JavaScript
• Strong working knowledge of React
• Comfortable working with GitHub in a production environment
• Proven experience shipping real UI to real users
• Strong attention to layout, responsiveness, and detail
• Able to work independently with minimal oversight
• Prior contract or freelance experience is a plus

Responsibilities

• Design and implement custom web forms using CSS, HTML, and JavaScript
• Work within and occasionally extend React applications
• Build clean, responsive layouts using modern CSS (Flexbox, Grid)
• Commit work via GitHub following standard PR / review workflows
• Own each form implementation end-to-end, including documentation
• Produce a client-facing deployment instruction page for each form that includes:
• Copy/paste-ready code
• Clear deployment instructions
• Screenshots of each form page
• Screenshots of the form embedded on the target site (mobile + desktop)
• Ensure all deliverables are bug-free and production-ready

Delivery & Payment Expectations

• Work is considered complete only when the deployment instruction page is finished and published
• Payment is tied to completed, accepted deliverables (not hours worked)

Compliance Note

As part of onboarding, contractors are required to complete identity verification via Veriff to confirm eligibility and compliance with international sanctions regulations.
