Founding Engineer - Infrastructure

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.

This is the part most companies don't have yet, and you'd own it.

Temper is two hard infrastructure problems stacked on each other:

1. A mini cloud platform: basically a Vercel for integration runtime. Every customer's integration code runs on it: durable execution, sandboxed isolation, self-healing when things break.
2. The agent infrastructure: coding agents that write, test, and deploy that integration code, running at scale in production.

On top of both, we give customers full observability into everything their integrations and agents are doing. And we ship the whole thing as a single-tenant, self-hostable product. Customers can run Temper inside their own cloud.

That's your surface area. You own it end-to-end.

You'll be our first infrastructure hire, working directly with Nick (CTO).

• Own the infra and platform layer: the runtime, the agent infrastructure, the observability pipeline, the self-hostable single-tenant deployment story.
• Set the engineering patterns every future infra hire builds on.
• Build the team. You'll help us hire it, pulling strong engineers from your network, and within a year you're leading the team that owns this domain.
• Work as a peer to the founders. We need your opinion, not just your code.
• Ship to production constantly.

This is a leadership track. You start as the person who owns infra; you grow into the person who leads it.

We're not building a CRUD app. Running coding agents and a multi-tenant integration runtime at production scale means we hit the most bleeding-edge problems in AI and agentic infrastructure before almost anyone else: sandboxing untrusted agent-generated code, durable execution for agent workflows, observability for non-deterministic systems, packaging all of it to self-host.

If you ever want to start your own infrastructure company, this is the launchpad. You'll see these problems first, solve them in production, and build the instincts the next wave of infra companies will be built on.

• 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.

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

• 3+ years at a high-growth startup. You've operated in fast, ambiguous, under-resourced environments, not just bigco with bespoke tooling and fuzzy impact attribution.
• You've run Kubernetes in production. Operated it, scaled it, debugged it at 2am, not kubectl apply'd a tutorial.
• You've owned infrastructure or a platform end-to-end: shipped it, scaled it, kept it alive. Owned, not “contributed to.”
• You code with AI agents and lean into it, but have the taste not to ship slop.
• Strong technical opinions, held loosely. You change your mind when the evidence says so.
• You don't wait to be told what to do.
• You want a true early-stage, in-person experience in SF: fast-paced, 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
