01. The Problem

Lack of connectivity is the most fundamental problem in the physical economy.

The physical economy runs on networks of interconnected companies, but on systems that were never designed to talk to each other. Every time two companies need to exchange data, someone builds a custom integration by hand: business analysts, integration engineers, QA. Manual, every time. (Google EDI if you haven't. It's wild.)

A lot of companies have tried to fix this. Nobody has. We think AI agents are the way.

02. What We're Building

Temper is an agentic integration platform for the real economy. Specialized AI agents handle the full lifecycle: gathering requirements in plain English, generating integration code, testing, deploying, and keeping integrations alive in production. When something breaks, the agents fix it.

We have paying enterprise customers and real integrations running in production. There's more demand than we can keep up with.

Seed-funded with over $8M raised. Earliest team of under 10.

03. What You'd Design

You'd own two product surfaces.

Agentic UX: the interface where people and coding agents build integrations together. Think conductor.build.

Platform UX: the mini-cloud our integrations run on. Think Vercel or Railway. Deploys, runtime, observability, logs.

You design it and you ship it. Design engineer means exactly that.

04. The Founders

Daniel (CPO) grew up in his family's trucking business. Built the freight product at Hive, Europe's leading eCom logistics startup, from 0 to $M. Hardware-native engineer who taught himself to code.

Heinrich (CEO) ran 100+ person warehouse operations at Amazon, then consulted on system integrations at KPMG. Built Hive's largest revenue line from zero.

Nick (CTO) built Lilith at 16, led an offensive security program for a nation-state, entrepreneur for 8 years. In eCom, he led the tech that scaled a company from 0 to $100M in 3 years.

Daniel and Heinrich built Hive from pre-seed to 400+ people. They've been living this problem for years.

05. The Role

You'd be our founding designer, working directly with Daniel (CPO) and alongside some of the strongest engineers working in HCI and agent systems today.

You'll own design end-to-end across the agentic ADE, the platform, and the brand, and set the design language every future hire builds on. You're in the codebase, not handing off Figma files. We need your taste, not just your output.
