Founding Engineer

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.

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.

The reason this is interesting to work on: these aren't chatbots or thin wrappers on an LLM. The agents do actual work with actual consequences in production systems.

Some of what you'd build:

• Agent orchestration across multiple specialized agents coordinating complex workflows
• Platform engineering: basically a mini Vercel for integration runtime with durable execution
• Self-healing systems that detect failures and recover autonomously in production
• A growing knowledge base of undocumented systems that gets smarter with every integration

Nobody has shipped this kind of platform at production scale yet, even in other verticals.

• Daniel

  Grew up in his family's trucking business. Built the freight product at Europe's leading eCom logistics startup, Hive, from 0 to $M and taught himself to code well enough to ship a real product in under a year.

• Heinrich

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

• Nick

  A hacker at heart: 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.

Together, Daniel and Heinrich built Europe's leading eCom logistics startup from pre-seed to 400+ people. They've been living this problem for years.

We care about the craft. We move fast and want to build something we're proud of.

You'll be our first engineering hire. You're building the team.

• Own core systems end-to-end: agent platform, infrastructure, integrations runtime.
• Set the engineering patterns that every future hire builds on.
• Work directly with the founders. We actually need your opinion, not just your code.
• Ship to production constantly.

What you build in the next year or so will shape the entire system. Most of the important decisions haven't been made yet.

We need you to breathe agentic coding and be comfortable working with multiple agents in parallel, leaning into AI. We trust you'll pick up the rest.

• You've shipped real things end-to-end, multiple times. Owned them, not just contributed.
• You code with AI agents and lean into it, but you have enough taste to not ship slop.
• Strong technical opinions, but you change your mind when the evidence says so.
• You don't wait to be told what to do.
• You want to do the best work you've done so far.
• You want a true early-stage, in-person experience in San Francisco: we operate fast-paced and with high intensity.

• Top-quartile pay
• Founding equity
• A top-tier office in San Francisco
• Equipment for maximum productivity: M5 MacBook Pro & more
• Full health coverage, 401(k) match
