Our Principles & Values:

At fainin, we're committed to navigating our journey guided by a distinct set of principles. We believe in having a clear actionable standard set for daily action — a set of guiding stars that illuminate our path forward aligned with our vision and values. These principles aren't just words on paper; they're the essence of how we operate daily. They embody our collective values, define our behaviors, and steer our decision-making processes. They're the unwavering standards that anchor us in our pursuit of excellence. By embracing these principles, we empower each team member to act with confidence and purpose. They serve as our North Star, offering direction, alignment, and a constant reminder of who we are and what we stand for.

• Growth-mindset. Be proactive and accept change. Especially in the early days, we require leaders, not followers, taking responsibility on their topics, setting and keeping the bar high.
• Self-responsible, reliable & careful. We execute with care and diligence to remove “code smell”. Keep files clean, check your spelling, apply our code guidelines and document your work. Be responsible beyond your areas of responsibility.
• React to other peoples messages in group chats at a minimum once daily so everyone knows we are on the same page especially the person that put in the work. Alignment and appreciation is key.
• Authenticity. Towards yourself and others. Internally and externally.
• Minimize communication overhead, make up your mind before meetings and conversation and if sending over information on any channel give a one sentence note on the rationale behind.
• Low Hierarchy. Everybody participates and takes responsibility in tasks that are not necessarily in the field of expertise. Participation and communication is key in all fields.
• Present a problem always with a solution draft. If hitting a roadblock, take time to clearly state the problem and figure out some possible solution before interacting with the team for help. This is a thing of respect and ownership, others are not meant to fix the problem one is responsible for.
• Keep up a healthy effective communication. Everyone is responsible to pause and cut interaction immediately that runs into the wrong direction - we have conscious phases of concentrated work. If meetings do not add value to your work or you can not add value to the conversation, you are allowed and encouraged to leave.
• Be on time, always, it's about respect for other people and the team's output. In any case there is any unforeseen delay, we give a written notice as early as we know to be late.
• Allow mistakes. It’s human to have weaknesses. Everyone has them, be always kind to yourself, however do not accept them to affect the team's standard to drop. Use tools to support you or discuss with the team on how someone with a strength in this field can support you. Follow an open-minded feedback-culture.

Meet the Stellar Minds Behind Our Startup

At the heart of our dynamic startup are four visionaries, Kevin, Johann, Jan and Max, whose passion and expertise set the tone for our journey. All four of them have worked together for more than 3 years already since they were students. Supported by the incredible talents of Luisa, Marvin and Elias, our team is a vibrant blend of diverse skills and shared values.

We are united by a common goal: to make fainin the most efficient platform in the sharing economy.

Kevin, our Chief Technology Officer, is steering our technological endeavors and has developed both our (web-)app and backend. His leadership ensures that our platform remains at the forefront of technology, continuously evolving to exceed user expectations.

Our startup isn't just a workplace; it's more as a high-performance sports-team united by a common purpose. The office exudes warmth, with at least one set of bedding always on standby and cabinets stocked with 100kg of ingredients for communal meals, from hearty lentil dishes to flavorful rice and couscous bowls.

And because balance is key, our team ensures that fitness is woven into our daily routine through random push-up challenges and a marathon bet. This unique blend of passion, creativity, and camaraderie is what sets us apart, fueling our motivation and propelling us towards success. Welcome to the spirited world of our startup ✨

Please also note:

Research indicates that men typically apply to jobs when they meet about 60% of the criteria, whereas women and other members of marginalized groups often apply only if they fulfill every requirement. Therefore, if you possess most of the qualifications but don't meet every single point on the job description, we encourage you to reach out.

Moreover it is more about the People than the skills. We would like to encourage you to write a cover letter in which you tell us why you, fainin and sharing economy startups, are the perfect fit for you personally.

After that we'd love to have a conversation and explore whether you could be an excellent fit for the role.

We look forward to hearing from you.
