Entrepreneurial Full Stack Web Developer / Technical Co-Founder (m/f)


This is your mission

  • Phase 1 (Bootstrapping): You will be prototyping rapidly and developing a MVP (minimum viable product) independently by making use of your holistic full stack developer skillset.
  • Phase 2 (Scaling): Following initial product traction and/or a significant investment round, your attention will shift from speed to perfection by creating a customer-focused masterpiece of features and usability while building up a team of top notch developers.


This is what you bring

Professional Expertise

  • You are a Full Stack Web Developer. We realize that one can hardly master all aspects of it to perfection, so we are looking for a T-shaped competence instead. Your deep knowledge as a backend developer (e.g. Ruby, Python, Node.js) is accompanied by adequate capabilities in the likes of frontend development (e.g. HTML5, CSS, JavaScript or jQuery), design, user experience, databases and infrastructure. A mix of competencies that allows you to develop and release a product independently from A to Z, which you have successfully demonstrated in the past.
  • Next to respective programming languages, you are also experienced in modern development frameworks (e.g. Rails or Django, Bootstrap or Foundation) for realizing a viable product more efficiently and rapidly.
  • Having a solid university degree, startup experience and/or demonstrated business acumen is considered a plus. Experience in using online brokers / trading platforms is a strong plus.

Methodological Competence

  • You are familiar with methodologies of orchestrating stakeholders (SCRUM or the like) to a point where you could introduce them to a team.
  • Knowing effective tools for a design first approach (e.g. ZURB), agile development (e.g. Pivotal Tracker) and efficient team communication (e.g. HipChat) will help you keep things organized and transparent.

Social and Personal Skills

  • We realize that being a web developer requires focus and concentration, probably most easily achieved in peace and quiet. However, as technical co-founder your job might also develop towards more leadership and representation. Thus we are looking for a candidate with good communication skills in English (and German as a plus), joy in working in a team, and the ability to manage conflict.
  • Acting entrepreneurial additionally requires sense of responsibility, ability to work towards goals and in particular independence and self-motivation.


This is what you get

  • High impact: you will be the first to join! You will be working closely with the CEO - an experienced serial entrepreneur - as well as exceptionally smart top management peers to come, who will both value and rely on your work and input.
  • The right culture and values! Let’s create them jointly. Are you thinking along the lines of no politics, results over face time and ideas over hierarchy? Well, here we go.
  • Huge financial upside! We know there are loads of companies out there that pay you nicely by the hour. However, we are looking for an entrepreneurial mind, willing to put in some sweat in exchange for a significant share in a high potential venture. Be a well-paid “code monkey” today or join us and become so much more – up to you.


What else to know

Remuneration: Sweat Equity (in phase 1) and added competitive salary (in phase 2).
Starting Date: ASAP (having smaller projects on the side is ok in phase 1).
Location: Hamburg, Hannover or Berlin (mostly remote work in phase 1).
