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.

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.
