Design Engineer

AI is crossing a threshold. Systems of agents are beginning to do consequential work unattended, for hours at a time. Plasma builds what those systems need: durable memory, shared context, budgets and approvals, and a record of everything that happens — the infrastructure that makes autonomous organizations trustworthy at scale.

We're looking for a frontend engineer to work alongside our CTO and shape Plasma's user experience. An AI-native product builder with both technical expertise and good taste.

Plasma's users are technically demanding operators of autonomous systems — clarity, information density, and precision matter as much as aesthetics. If you're interested in owning design and engineering direction from the ground up, this role is for you.

• Frontend Ownership — Design, architect, and implement Plasma's core product UI/UX

• Complex Systems UX — Translate dense, technical workflows into interfaces that make autonomous systems easier to understand, operate, and trust

• Design Systems — Build and maintain the design system and component library that define Plasma's product identity and scale across the application

• Product Direction — Partner with the founding team to shape what gets built and make the right tradeoffs between speed, scope, and craft

• Strong frontend engineering: React, Angular, or Vue, plus TypeScript, modern CSS, and animations

• Visual and interaction design sensibility that's immediately recognizable in your work

• You ship real products, not just prototypes

• A portfolio that demonstrates craft — shipped products, personal projects, open-source tools

• Experience building modern enterprise SaaS or systems at companies known for design-engineering excellence (Vercel, Linear, Figma, Stripe, Notion, Apple) is a plus, not a requirement
