Founding AI Engineer

TL;DR

We're looking for a founding AI Engineer to help build the AI colleague every sales professional wishes they had. You'll own the agent stack end-to-end - from model selection to database (knowledge graph) structure and search algorithm development. Must be curious, experimental, and obsessed with agentic systems.

Why join

We’re a small, talent-dense team of engineers building a generation-defining company from Stockholm. We value speed, rigour, and extreme ownership. If you're obsessed with product, thrive in ambiguity, and want to push the edge of what agents can do, you’ll feel at home.

You’ll work on pushing the cutting edge in the agentic stack - including LLM fine-tuning, knowledge graphs, memory, orchestration, and intelligent retrieval. Not another chatbot.

We're backed by founders and operators behind Lovable, OpenAI, Tandem Health, and Neo4j. Our customers across 10 countries report 90% less prospecting time, 3x market coverage, and 2x customer meetings.

What you'll do (responsibilities)

In one sentence: Build the next generation agentic system.

Design and build agentic workflows powered by LLMs, vector search, and knowledge graphs
Build autonomous background agents that run real revenue workflows — triggered by schedules and CRM events, working across email, CRM, and the web
Own the agent stack end-to-end: from infrastructure to product logic
Ship fast: test ideas, run experiments, iterate daily
Shape the product, the stack, and the culture from the ground up

Who you are

Cracked engineer obsessed with building great software
Comfortable with ambiguity, early-stage chaos, and fast iteration
Thrive on new tech - LLMs, knowledge graphs, agents, you name it
Care more about solving problems than polishing abstractions
Fully committed to the mission: not "just a job"

What we offer

A team of obsessed engineers, full of speed, rigour, and grit
Mission-driven, no-BS culture: experiment, ship, learn
Meaningful equity through qualified employee stock options (QESO) from day one
Fully on-site in Stockholm - we believe in working together
Top-tier compensation package

Our stack

The system integrates knowledge graphs, memory, and agentic workflows to deliver real help - not just summarisation or search. We're backed by founders and operators behind Lovable, OpenAI, Tandem Health, and Neo4j.
