Senior UX

We're seeking 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. #J-18808-Ljbffr
