We're seeking for a Senior UX/UI Engineer in Brazil - 100% remote
Type: 6-Month Contract (with strong potential for extension)
Location: Remote
About the Role
We’re looking for a Senior UX/UI Engineer to help build and improve internal web-based user interfaces for our Site Reliability Engineering teams. This role is ideal for a front-end engineer who loves to get hands-on with React and enjoys improving user workflows, not just coding layouts.
You’ll be working on existing internal React applications (built by engineers, for engineers) — streamlining them, improving usability, and helping implement new functionality.
What You’ll Do
* Enhance and reorganize an existing internal React app to improve usability and maintainability.
* Build and implement intuitive web-based interfaces used daily by internal engineering teams.
* Collaborate with engineers and stakeholders to identify UX pain points and deliver better workflows.
* Bring a strong design sensibility to UI decisions, even if design is not your primary focus.
Must-Have Skills
* React expertise — deep hands-on experience building and improving production React applications.
* Experience delivering solutions using multiple front-end languages or frameworks (you’ve picked up a “second and third language”).
* HTMX experience (required).
* Lit experience is a plus (not mandatory).
* Experience implementing and improving internal web-based applications.
* Comfort working in the UX layer — improving workflow, usability, and user experience (not just layouts).
Nice-to-Have Skills
* Some UX design experience — wireframing, talking to users, or journey mapping.
* Experience with Go or Python (enough to be dangerous).
* Familiarity with internal tools or applications (preferred over public-facing apps).
Soft Skills
* Go-getter mentality — eager to learn, fix, and improve from day one.
* Curious and proactive — someone who would say, “I saw the issues in your React app, fixed them, and I’m ready to move forward.”
* Focused on delivering impact to end users — able to articulate what you built, why it mattered, and how it improved the experience.
