We’re looking for a Software Engineer focused on Product Experience and UX to help us craft elegant,
- impact user journeys across the Paynest platform. You’ll collaborate with Product and Design to implement frontend features, reduce friction, and drive intuitive workflows.

• Collaborate with Product and Design on flows, wireframes, and usability.
• Proactively identify UX friction and suggest scalable, thoughtful solutions.
• Ensure design consistency across devices, edge cases, and user states.
• Contribute to our component library and design system.
  
  
  

You Are

• A
  - leaning engineer with 1–3 years experience in modern web development (React, Vue, etc).
• Detail-obsessed and empathetic—you spot bad UX before users do.
• Fast, iterative, and
  - driven—you want to get things in front of users quickly.
• Comfortable collaborating in
  - functional squads and giving design input.
• Opinionated about product quality and happy to own things
  -
  - end.
  
  
  

Nice to Have
