Job Description:

Intro
You love hacking, but want to build something real? Why build alone? Join our small, hands-on team to create AI products and launch our own ideas. You’ll have real freedom, shape the tech, and share in the success (salary, earnings share and equity in products we launch).

About us
We're a small, focused team that values humble, practical builders. We're entrepreneurs ourselves, and we love creating new products with exciting and innovative technology. If you have a startup spirit, enjoy side projects, and want to see your work make a real impact, we'd love to connect.

Tasks
- Leading projects from initial concept through to production-ready apps.
- Choosing and evaluating the best tech stack and tools for each project.
- Building front-end and back-end solutions primarily with TypeScript (React, Node, Tailwind).
- Integrating AI solutions using tools like LangChain, OpenAI, Google Vertex AI, and Azure AI.
- Setting up analytics and event-tracking (e.g., Mixpanel, PostHog).
- Validating technologies through practical, real-world testing.
- Collaborating closely with designers, researchers, and users to build truly useful products.
- Communicating directly with clients—asking insightful questions and clarifying goals.

Requirements
- 3–5+ years of experience in full-stack development (React, Node, TypeScript).
- Experience taking the technical lead on at least one major project.
- An entrepreneurial mindset—you enjoy turning ideas into working products.
- Comfort with ambiguity and an ability to work independently.
- Great communication skills and a collaborative spirit.
- A passion for learning and experimenting with new technologies.
- Big Bonus: previous experience or side projects involving AI.

Benefits
- Competitive salary plus annual bonus based on company performance.
- Real equity in the products we build together, with an option to invest further.
- Customizable perks (transportation pass, gym membership, rental bike)—choose what fits your life.
- 4-day work week with high flexibility.
- Autonomous, self-managed work environment.
- Experienced, flat team structure—no corporate hierarchy here.
- Opportunity to build practical, valuable AI products used by real people.
- Remote or hybrid work model: 2 days/week in our Berlin coworking space, the rest remote.

Closing
How to apply: We don't need a polished CV. Just send us your LinkedIn profile or a quick overview of your background, plus short answers (2–5 sentences each) to these prompts:
- A project you built yourself and what made it special.
- Why you're excited about AI—especially something you think most people get wrong.
- A full-stack project where you took technical leadership.
- A clever non-technical solution or "hack" you've used to gain an advantage.
This helps us quickly understand who you are and what motivates you.
