AI Fintech Engineering Intern - Backend & Data Systems

<p>ImmoSteuer365 is building an AI-driven fintech product for real estate investment decision support in Germany. The product helps private investors understand the long-term tax, financing, renovation and cash-flow impact of their real estate decisions before they commit capital.</p> <h2>Tasks</h2> <p>We are opening a short voluntary internship opportunity for students who want to gain hands-on experience in an early-stage fintech/AI startup and learn how backend systems are built in a real product environment.</p> <p>This internship is designed as a 10-week learning-oriented and study-related practical experience. It is suitable for students who want to explore backend engineering, relational databases, REST APIs and early-stage product development while working on a clearly scoped technical learning module.</p> <p>During the internship, you may work on small backend-related tasks such as drafting database table structures, building a small CRUD prototype, supporting API endpoint examples, preparing technical documentation, writing test scripts, or exploring how frontend data flows connect with backend logic.</p> <p>You will work closely with the technical lead and founder, receive task guidance, code review and regular feedback. The focus is on learning through a real startup context and producing a concrete project outcome that you can include in your CV or portfolio.</p> <h2>Requirements</h2> <p>We are looking for students with basic Python knowledge, basic SQL knowledge and curiosity about backend development in a real product environment. Experience with FastAPI, Flask, PostgreSQL, MySQL, Git or REST APIs is a plus, but not required.</p> <p>You do not need to be an expert. What matters most is reliability, willingness to learn, clear communication and the ability to work on a small technical module step by step with guidance.</p> <p><strong>Time Commitment</strong></p> <p>The internship is planned for 10 weeks. The expected workload is flexible and limited, ideally around 15 hours per week.</p> <p>There are no fixed working hours. We will agree on a small learning module at the beginning and hold regular check-ins to support your progress. This internship is not intended to replace an employee role or carry production-critical responsibility.</p> <h2>Benefits</h2> <p><strong>Compensation &#x26; Setup</strong></p> <p>This is a voluntary, unpaid internship designed for learning, orientation and study-related practical experience. The internship is limited to 10 weeks and does not automatically extend into a paid role.</p> <p>After completion, we can provide an internship certificate. Depending on your contribution, we may also provide a reference letter or LinkedIn recommendation.</p> <p>If both sides are interested and ImmoSteuer365 later has a paid position available, we can discuss a separate paid internship or working student contract. This would be a new agreement.</p> <p><strong>Benefits</strong></p> <p>You will gain hands-on backend experience in a real fintech/AI startup, work directly with the founding team, receive mentoring and code review, and build a concrete technical outcome for your CV or portfolio.</p> <p>You will also get exposure to early-stage startup execution, including how product, engineering, user feedback, funding raising and VC development connect in practice.</p> <p>After completion, we can provide an internship certificate. Depending on your contribution, we may also provide a reference letter or LinkedIn recommendation.</p> <p>If you are looking for a short, practical internship where you can learn by contributing to a real early-stage fintech product and understand how an AI startup is built from the inside, we would love to hear from you.</p> <p>Find <a href="https://www.arbeitnow.com/">Jobs in Germany</a> on Arbeitnow</a>
