Founding Engineer

Temper | Founding Engineer | San Francisco (In-Person) | $150K–$250K + 0.5–1.5% 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 from users 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 TECH
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.

THE FOUNDERS
Daniel grew up in his family's trucking business. He 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. He built Hive's largest revenue line from zero.

Together they built Europe's leading eCom logistics startup from pre-seed to >400 people.

Nick is 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.

THE ROLE
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
• Ship to production constantly

Most of the important decisions haven't been made yet.

STACK (helpful but not required)
TypeScript, React, Bun, Effect-TS, PostgreSQL, Kubernetes, AWS.

We need you to breathe agentic coding and be comfortable working with multiple agents in parallel.

YOU MIGHT BE A FIT IF

• You've shipped real things end-to-end, multiple times
• 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 a true early-stage in-person experience in San Francisco

WHAT WE OFFER

• Top quartile pay (cash & equity)
• As member of the founding team, every decision is yours to shape
• Top-Tier office
• M4 MacBook Pro & equipment for maximum productivity
• Full health coverage, 401(k) match

PROCESS

• Screen (20 min)
• Deep dive (45 min)
• Technical (45 min) — design a system, no leetcode
• Paid work day, real task from backlog, in-person
• Offer

We move fast. Expect under 2 weeks from first call to offer.
