Stellenbeschreibung
Stellenbezeichnung: Technical Co-Founder // CTO (Go and React)

We’re looking for a high-caliber engineer to join as a Founding Engineer. You should be deeply hands-on with code, technically opinionated, and capable of building production systems from scratch. This is a role for someone who enjoys execution but also has the potential (or ambition) to lead technology at a company-defining level.

🔍 What You'll Do
  • Build and own core infrastructure and backend systems
  • Design and implement APIs, data models, and scalable services
  • Collaborate closely with founders on product direction and technical architecture
  • Ship code fast, validate assumptions, and iterate
  • Lay the groundwork for the future engineering team (tooling, processes, and architecture)
✅ Core Technical Requirements
  • Proficient in one or more modern backend languages (e.g. Python, Go, Type Script, Java, Rust)
  • Strong systems design skills — you can model real‑world systems and reason about scale, latency, and trade‑offs
  • Comfortable building from zero — greenfield work doesn’t scare you; in fact, you prefer it
  • Experienced with cloud infrastructure — AWS, GCP, or similar;
    IaC (Terraform, Pulumi, etc.) is a plus
  • Competent with databases and data modeling — SQL and No

    SQL, designing schema for scale
  • Comfortable writing tests and deploying production systems — you care about code quality and reliability
⭐ Bonus Experience (Not Required, but Valuable)
  • Worked at a Pre‑Seed or Seed‑stage startup through to Series A
  • Built or deployed software used by enterprise customers
  • Experience with applied machine learning or MLOps (not just academic or notebook‑based work)
  • Exposure to event‑driven architectures, streaming systems (Kafka, etc.), or real‑time data pipelines
  • Frontend experience in React, Type Script, or similar modern frameworks
📈 What We Offer
  • Early‑stage equity and the opportunity to shape foundational decisions
  • High ownership, zero bureaucracy — build what matters, fast
  • Founders who value engineers, ship code, and work closely with you
  • A role that grows with you — if you have CTO potential, you’ll have a path
You should apply if:

You’re a product‑focused engineer — you solve problems through code, you like building things that work, and you’ve got the technical depth to back it up.
