Technical Co-founder - AI Engineer

About us

We're building something big in the future-of-work space, with the talent, technology, and backing to move fast and aim high. We work in tight cycles, give honest feedback, and trust each other to own big, complex problems. Joining now means becoming part of the core team at the very beginning – with the chance to shape everything we build together, among others, both the product and the company.

Who we are

We're a stealth startup disrupting an entire industry, led by founders with proven expertise in product development and leadership – together with passionate engineers who have built state-of-the-art solutions for organizations of all sizes, with and without AI. Our hub is currently in central Stockholm. For a role like this, we value in-person collaboration – not because we have to, but because we want to build an atmosphere that makes you want to be here, and we believe you are integral to building that culture.

The opportunity

We're looking for a Technical Co-Founder to join as a core member of the founding team. It's not a traditional role but an opportunity to shape both the product and the technology behind it. Rather than starting from scratch, you'll build on what's already in motion - refining architecture, embedding AI, and driving our next stage of growth. Working closely with the founders, you'll set the technical direction, influence product strategy, and contribute hands-on code in the early phases.

Key Responsibilities

  • Own the technical roadmap and system architecture
  • Build and scale the core product
  • Evaluate and integrate generative AI services, including LLMs, embeddings, and agentic patterns
  • Establish, own, and invent engineering practices including CI/CD, observability, and cloud infrastructure as code
  • Partner closely with product, design, and business founders to shape product-market fit
  • Represent technology in discussions with partners, customers, and investors
  • Recruit, hire, and mentor engineers as the team grows

Must-Have Skills

  • Proven experience shipping scalable and complex solutions in projects with diverse tech stacks, where the right tool is used for the right problem
  • Practical experience with generative AI/LLMs, including prompt engineering, MDD, AI / LM Ops & Eval, and more.
  • Strong understanding of cloud infrastructure (Azure, GCP, or AWS) and Infrastructure as Code
  • Ability to operate both strategically (vision, architecture) and tactically (hands-on coding)
  • Curiosity, resilience, and drive to build in an early-stage, high-velocity startup environment
  • Experience building high-trust, low-ego cultures.
  • Experience with security, compliance, and data privacy (GDPR, DevSecOps)

Nice-to-Have Skills

  • Prior experience as a founder or technical lead in a startup

  • Experience with event-driven architectures, graph, relational and/or vector databases

  • Experience growing and managing engineering teams

  • Exposure to fundraising or investor dialogues from a technical perspective
  • An understanding of the consequences of the EU AI Act, and the requirements it puts on our business.
  • Proven ability to truly innovate.
  • Ability to understand and weigh the pros/cons of spending engineering hours vs buying a finished solution from another company

What we offer

  • A founding role with equity ownership
  • Real influence over both product and company direction
  • Close collaboration with experienced founders and a high-trust, low-ego culture
  • The opportunity to build something industry-changing from the ground up
  • A chance to build something we think might fundamentally change the way the industry operates in the whole world
