# Design Engineer, SimplyCodes

- **Company:** PRODUCTIVE PRODUCTS LLC

- **Published:** November 9, 2026
- **Apply:** https://www.juju.com/job/28_25303_25e271465fc51112644656be9e4cee10

## About the Role

We need a builder who already thinks in both design and code, has a real human-computer interaction background, is fluent with the AI tools that accelerate both, and wants to own consumer interfaces end to end. You partner directly with our Founding Designer and the founder to set and raise the consumer design bar across SimplyCodes and our shared design system., The craft you must already own: a real human-computer interaction background, not a gloss of design vocabulary; a very strong design eye, proven by a live portfolio of shipped work; building production interfaces in React, TypeScript, and CSS; fluency in Figma; and AI coding and design tools as force multipliers you verify by hand. A bonus, not a requirement: SEO experience - understanding how search-aware design compounds discovery on high-traffic consumer pages.

Comparable experience we accept: a frontend or design engineer with real design taste and an HCI background, a product designer who ships production React/CSS code, or a builder who designed and shipped a consumer product end to end.

## Description

* Prototypes that are the real thing. The design-to-engineering handoff is gone here. A direction is explored as a working prototype in a design tool and in production React/CSS in the same session, and the winners ship live.
 * Decision-shaped interfaces. The unit of every screen here is a verified claim or code and how sure we are that it works. Confidence has to render credibly, never oversold and never buried - motion physics, state, and typography doing trust work.
 * Cortex, the shared AI brain the company runs on. You work inside it daily, directing coding agents as force multipliers the way our founder does, and since August any operator here can change the rules the company runs on, live, without waiting on founder approval.

If reading that energizes you, keep going. If it feels overwhelming or underspecified, this isn't the right fit., * Working prototypes and shipped components. Directions taken from a sketch or interactive rig to production React and CSS without waiting for a handoff in either direction.

 * The polish and motion layer. Motion physics, micro-interactions, state transitions, spacing, and typography: the decisions that make a verification interface feel unmistakable and trustworthy.
 * Your seat charter. Within your first quarter you co-sign a charter for this seat. It names one machine-checkable number that proves the seat is working, and a high-ownership partnership model with our Founding Designer and the founder., * Calls with company stakeholders. Short conversations with the people you'd build beside, including our Founding Designer.
 * Conversation with the founder. How you see a screen, how you use your tools, and what you'd elevate first across SimplyCodes and /shop.
 * Paid work trial (PRJ-75). A paid real-work trial in our environment: taking a live consumer verification component or SimplyCodes screen from design direction to shipped production React/CSS inside our design system. We look for visual taste, interaction physics, how you use AI tools as force multipliers, and how we collaborate together.
