Job description

Help us build the contract performance platform of tomorrow.

We are building an AI-native Contract Performance Management platform aiming to become the European leader.

Every business runs on contracts. Millions move every day based on agreed terms. But most companies can't tell you what their contracts are actually worth. The truth only surfaces in costly and time consuming audits.

Contracts have become the 'financial infrastructure of the business' but no software caught up. We're building the layer that do catch up, for the European mid-market, with AI doing the heavy lifting from day one.

Come help us solve a real pain in a huge market working with an experienced team and a modern tech stack where we ship multiple times a day.

About Us

• Founded in 2023
• Five co-founders with six prior exits
• Headquartered in Aarhus
• Flat org with no layers between you and the founders
• All smiles and happy faces

What you'll build

• AI-native from the core. LLMs, agents, retrieval - not a side feature. The heart of how contracts become structured financial truth.
• Real-time financial intelligence. Earned, projected, missed and actual value across thousands of contracts and millions of transactions, continuously computed.
• ERP integrations done right. Dynamics 365, SAP, Oracle, NetSuite, e-conomic. Robust, idempotent, observable.
• Live, reactive UI. Dashboards and projections that update in real time. WebSockets, not refresh buttons.
• Foundational architecture. The calls you make today shape the platform for years. The CTO backs your judgement.

This isn't a backlog-ticket role. You'll own surfaces end-to-end, design, ship, monitor, talk to the customer, watch the impact land.

The stack

Infra

Kubernetes, Hetzner, Github, Patroni, Postgres, Redis, S3, Github actions

Frontend

React, Inertia.js, Typescript, Tailwind, ShadCN

Backend

PHP, Laravel, Reverb, Horizon, Laravel AI

AI

Azure private LLM deployments, Laravel AI, Laragent, OpenAI Embeddings, PgVector

Quality

Pest, PHPStan / Larastan, Playwright, CI pipelines

Modern, opinionated, AI-native. Built to ship fast without losing sleep.

How we imagine you

• 5+ years building production systems - not prototypes
• Strong in Laravel/PHP, comfortable in React when the work demands it (or the other way around - backend-leaning is fine)
• Real LLM-in-production experience: prompts, retrieval, evaluation, cost, latency, evals. Not 'I tried ChatGPT once.'
• Comfortable in messy domains - financial logic, integrations, reconciliation, edge cases that don't fit on a Figma frame
• Owns what you build - design it, ship it, monitor it, fix it
• Pragmatic. You make the right tradeoff between elegance and speed without ego

Bonus if you've worked with: pgvector, Inertia.js, Vapor / serverless, Reverb or another WebSocket stack, ERP integrations, or Python-side AI tooling alongside PHP.
