Job description

Clera is recruiting for Temper. Applications through this listing reach Clera via Workfully.

Full-time, in person in San Francisco, United States. Published annual salary: $150,000–$250,000 plus meaningful equity.

The problem

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

The physical economy only works as a network of interconnected companies, but it still runs 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. All 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 to finally connect the physical economy.

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 it, deploying it, and keeping it alive in production. When something breaks, the agents fix it.

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

Seed-funded, with over $8M raised. Still an early team, under 10 of us.

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.

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.

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.

You might be a fit if

• You know the difference between fine and excellent, and you ship excellent.
• You implement and ship production frontend yourself.
• You've designed real B2B SaaS products: dense, technical ones.
• You're plugged into agentic and HCI design. You know what good agent UX feels like.
• You hold strong opinions and change them when the evidence says so.
• You move independently.
• You want to do the best work of your career.
• You want a true early-stage, in-person experience in San Francisco: fast-paced, high intensity.

What we offer

• Top-quartile pay
• Meaningful equity
• A top-tier office in San Francisco
• Equipment for maximum productivity: M5 MacBook Pro & more
• Full health coverage
