Design Engineering forAI-native product teams

Your engineering already moves at AI speed. Design Engineering keeps design moving with it: a designer who understands the technology well enough to direct AI agents, build working prototypes, and make product decisions next to your developers.

What Design Engineering covers

Design that lives close to the product: prototypes, systems, and interfaces built with the same tools and constraints as engineering.

AI-assisted design workflows
Design processes rebuilt around AI agents, so an idea reaches a testable state in hours instead of sprints.
  • Claude, Codex and Cursor workflows
  • Context and prompt design
Prototyping in real code
Interactive prototypes built in a real stack, so decisions are made on something people can actually use.
  • Working prototypes
  • Direct design-to-code handoff
Design systems in code
Component libraries maintained as living code, so design and implementation stay in sync as the product changes.
  • Component libraries
  • Design tokens
Product interface design
Interfaces for complex SaaS and B2B products, designed with a realistic view of what the stack can support.
  • Dashboards and admin tools
  • Complex workflows
Designing AI features
Design for products where the interface is an agent, a conversation, or a model output rather than a fixed flow.
  • Agent and chat interfaces
  • Model output and error states
Embedded in your product team
A Design Engineer working inside your team, in your rituals and your repository, at a 50–100% allocation.
  • 50–100% allocation
  • Monthly agreement

How we bring a Design Engineer into a team

A short path from identifying the bottleneck to having a Design Engineer in your everyday work.

1

Bottleneck assessment

We look at where design slows product development down compared with the pace your engineering already runs at.

Key Deliverables:

Analysis of the design bottleneck
Review of your current AI workflows
2

Matching the Design Engineer

We propose a person from our curated network based on capability, technical fluency, and fit with your team.

Key Deliverables:

Proposed Design Engineer
Scope and allocation plan
3

Working inside the team

The Design Engineer joins your everyday work: design, prototypes, and product decisions move at the same cadence as engineering.

Key Deliverables:

Working prototypes and interfaces
Contributions to your design system
4

Scaling or hiring

The allocation is adjusted as your situation changes. If the person becomes permanent capability, you can hire them.

Key Deliverables:

Adjusted allocation
Buyout on agreed terms

Co-founder & Design Engineer

The best product decisions come from someone who understands what the technology can actually do. That is what Design Engineering is about.

Why teams choose Design Engineering

Design Engineering is our specialty. It exists because product development changed and design had to change with it.

Design at engineering pace

Design stops being the step that everything else waits for.

Technical fluency

A designer who understands the stack makes fewer unrealistic decisions and creates less rework.

Curated network

Every Design Engineer is vetted for capability, AI fluency, and team fit before we propose them.

Option to hire

If the person becomes a permanent part of your capability, you can hire them onto your own payroll.

Trusted by leading companies

We work with product teams building business-critical digital products.
