Build the agentic world.
We're building the first complete agentic business system — a team of governed AI agents that structure operations, ship software, do the daily work, and scale with the business. It needs people who want to define a category, not just join one.
Frontier work, real stakes, true ownership.
This isn't a thought experiment. Our agents run inside live businesses every day — and the governance, reliability, and craft behind them are decided by the people on this page.
A mission that matters
We're answering the hardest question of this decade: how do you let AI run real work without losing control of it? Who authorized it, what it touched, can you prove it, can you stop it. Get that right and you change how every business operates.
Ownership, not tickets
You'll own outcomes end to end — from the primitive you design to the client whose business it runs. Small teams, short paths to impact, and the trust to make the call. We hire people who'd rather own a hard thing than be handed an easy one.
The actual frontier
Multi-agent orchestration, runtime governance, agent reliability at scale — the problems don't have textbooks yet. You'll write the patterns others copy. Forward-deployed engineers ship in real businesses; the platform team turns those lessons into Mainspring, Loom, Cadence, Aegis, Warrant and Ledger.
Heartblood and discipline, in equal measure.
We care intensely and we ship carefully. The way we work is the product: governed, accountable, fast.
Proof over promises
If we can't show who authorized it, what it touched, and how to stop it, we don't ship it. Accountability is a feature here — for our agents, and for each other.
Forward-deployed by default
The best ideas come from sitting beside the customer. Engineers go where the work is, feel the friction first-hand, and feed it straight back into the platform.
Small teams, high trust
Few people, real authority, clear ownership. We'd rather give five people a hard problem than fifteen people a committee.
Craft is non-negotiable
From the runtime to the marketing site, things should feel considered. We build for a 10,000-employee world while keeping the soul of a founding team.
Eight ways to build with us.
Vienna or Remote-EU. If your craft is here but the exact title isn't, write to us anyway — great people make their own role.
Senior Platform Engineer — Runtime
Own the heart of Mainspring: the runtime that executes governed agents at scale. Distributed systems, low-latency orchestration, real production load.
Vienna · Remote-EU — Apply →Forward-Deployed Solutions Engineer
Sit beside our clients, design the agents their business needs, and ship them on the platform. Part engineer, part consultant, all impact.
Vienna · Remote-EU — Apply →Agent Reliability Engineer (SRE)
Keep autonomous agents dependable in production. Evals, guardrails, failure recovery, observability — reliability engineering for systems that act on their own.
Vienna · Remote-EU — Apply →Security Engineer — Governance & Identity
Build Aegis and Warrant: the governance and identity layer that decides what every agent may touch. Authorization, audit, the kill switch. SOC 2, GDPR, real teeth.
Vienna · Remote-EU — Apply →Product Designer — Platform & Console
Make governed autonomy feel calm and legible. Design the console where humans direct, review, and trust a team of agents. Systems thinking and serious craft.
Vienna · Remote-EU — Apply →Developer Advocate
Be the voice of the agentic developer. Docs, demos, talks, and the community around our primitives. Help builders go from idea to a governed agent in an afternoon.
Vienna · Remote-EU — Apply →Enterprise Account Executive
Bring the agentic business system to enterprises that need governance, not hype. Sell the wedge, run the room, partner with forward-deployed teams to prove it.
Vienna · Remote-EU — Apply →Operations & People Lead
Build the company that builds the agents. Finance, hiring, and the systems that keep a fast team accountable — and, naturally, automate the routine away with our own platform.

"We don't hire for headcount — we hire for the people who'll define how the agentic world actually works. If that's the thing you can't stop thinking about, you belong here.— Clemens Grünberger, Founder, lastloop
