Product Engineer

About the role

We're hiring a **Product Engineer**; a rare hybrid who has lived at the intersection of product, design, and code. You've got a strong UX/UI foundation and real product\-management chops, and over the last couple of years you've become a genuine builder, shipping production code yourself with AI\-assisted tooling. You care about how things look, how they feel, and whether they actually work.

You'll own our design system, our aesthetic, and our visual identity inside the product; you'll run design reviews and UAT as team\-wide processes; and you'll ship code alongside the engineering team, fixing issues you find rather than filing them and walking away. This is a builder's seat with a designer's eye and a product owner's judgment.

Teserac, Inc. builds an AI\-native platform for data center observability, intelligence, and workflow automation. Our software helps operators monitor, analyze, and manage mission\-critical power and infrastructure systems in real time, supporting environments where clarity, speed, and reliability matter.

This is an opportunity to join a team working at the intersection of product design and engineering, shaping software used to understand and operate complex infrastructure. As a Product Engineer, you will help define how the product looks, feels, and functions, bringing strong product judgment to decisions that improve usability, quality, and consistency as the platform evolves.

Responsibilities* **The design system.** You'll define, document, and maintain a coherent component library, design tokens, and usage patterns so the whole team ships consistent, high\-quality UI. * **The aesthetic and visual identity in the app.** You are the steward of how Neuron™ looks and feels; typography, color, spacing, motion, and the overall craft of the interface. * **UAT as a process.** You'll design and run our User Acceptance Testing process for the entire team; defining what "done and correct" looks like before anything reaches a customer. * **Design reviews.** You'll lead them; setting the bar, giving actionable feedback, and keeping quality high across every surface. * **Fixing what UAT surfaces.** When you find an issue, you'll go into the codebase and fix it; front\-end bugs, UI regressions, polish, and the occasional deeper change. * **Web design when needed.** You'll lend your eye and hands to the marketing site and other marketing surfaces when they need it.

**Requirements**

Required Qualifications* Strong UX/UI design foundation, including experience translating product requirements and rough concepts into polished, usable interfaces. * Experience owning design systems and the visual craft of a product, including typography, color, spacing, motion, and overall interface quality. * Track record of making product prioritization decisions and sound judgment calls during product reviews. * Experience establishing design review and user acceptance testing practices that teams follow. * Experience prototyping and building real product UI within the same workflow, and shipping production code directly rather than only filing issues. * Hands\-on experience reading and fixing code in a production codebase, including resolving front\-end bugs, UI regressions, and polish issues directly. * Strong front\-end development experience with React, TypeScript, and CSS or Tailwind, using AI\-assisted development tools such as Cursor, Claude Code, Copilot, or similar. * Experience applying visual design judgment to improve product usability and quality in complex, data\-dense B2B or enterprise SaaS interfaces such as dashboards, observability, time\-series, or operational tooling. * Comfort working in an early\-stage, fast\-moving environment where processes are defined as the team goes. * Experience collaborating closely with engineering and partnering with product, leadership, and other cross\-functional teammates to guide reviews, user acceptance testing, and product decisions. * Eligibility to work in the United States.

Preferred Qualifications* Experience contributing visual design work to marketing websites or other web surfaces when needed. * Familiarity with Vite. * Familiarity with Django or Python for occasional deeper fixes. * Exposure to data visualization design.
