# UX Engineer, HCI

- **Company:** Spectraforce
- **Location:** Seattle, WA, United States (Remote available)
- **Contract:** Permanent contract
- **Skills:** Computer Animation, Artificial Intelligence, Software Product Management, Ui Patterns, TypeScript, ReactJS, Front End Software Development
- **Published:** July 24, 2026
- **Apply:** http://leoforce.us/Careers/Spectraforce/JobDetails.html?jobid=9996709f-bdef-477f-a53e-783f1ea4108f&OrgId=1&UserId=6265

## About the Role

* Strong frontend engineering skills in React, TypeScript, or equivalent.
 * Experience building interaction-heavy or experimental interfaces.
 * Strong product and UX instincts - you can tell when something is unclear or broken from a user's perspective.
 * Ability to prototype rapidly in ambiguous environments with incomplete specs.
 * Understanding of animation, responsiveness, frontend architecture, and UI performance.
 * Interest in HCI interfaces and how to design for trust, control, transparency, and recovery.
 * Comfort working at the boundary of design and engineering without clear handoffs.
 * Ability to move fast while keeping the user experience clear and usable.

## Description

You will sit at the intersection of design and engineering, building the AI interfaces that users actually interact with. This is not a UI maintenance role. You will prototype, test, and ship new interaction patterns for AI-driven experiences where established conventions do not yet exist.
This role is focused on HCI - building interfaces that make AI behavior understandable, controllable, and useful in real workflows.
What You'll Be Doing

 * Build and prototype AI-native product interfaces across web and mobile.
 * Create functional prototypes of new HCI interaction models, including streaming responses, multi-step task flows, real-time feedback loops, and system state visibility.
 * Translate design concepts into working code with high attention to usability, responsiveness, and motion.
 * Experiment with UI patterns that show progress, uncertainty, confidence, failure, and recovery clearly to users.
 * Build interfaces that let users supervise, correct, and redirect AI behavior without micromanaging the system.
 * Work closely with product, design, and ML teams to validate interaction ideas quickly.
 * Contribute to frontend architecture and reusable UI components for AI product surfaces.
 * Identify and fix usability, performance, and state management issues in AI-driven interfaces.
