Senior Developer (Python)

Location: Berlin, Germany (Hybrid position)

Type: Full-Time

Entry Date: Immediate

Job Description:

As a Senior Python Developer at Talonic, you'll have a hands-on role building, training, and optimizing AI-driven systems and data tools. You’ll work closely with our technical team to develop backend architectures, fine-tune AI models, and help manage large-scale data operations.

This role is perfect for someone with a deep curiosity for data, who enjoys solving technical challenges, loves experimenting with AI models, and wants to help shape a young and ambitious company.

At Talonic, we value curiosity, initiative, and a growth mindset. You'll have the support you need but also the freedom to test new ideas, explore modern technologies, and own your projects end-to-end.

Key Responsibilities:

• AI & Data Development: Work on building, fine-tuning, and optimizing AI models, with a focus on practical applications.
• Backend Engineering: Design and implement scalable backend systems using Python, FastAPI, and similar frameworks.
• Data Management: Handle large datasets efficiently, collaborate on data ingestion, preprocessing, and organization tasks.
• Experimentation: Prototype new features, AI pipelines, and backend improvements quickly and effectively.
• Collaboration: Brainstorm and innovate with the team to push the boundaries of our AI and data platform.
• Bonus Points: Experience with LangChain, Hugging Face, OpenAI models, or Retrieval-Augmented Generation (RAG) is highly desirable.

Qualifications:

• Bachelor’s or Master’s degree in Computer Science, Data Science, Software Engineering, or a related field.
• 5+ years of professional experience in Python development, ideally with strong backend or data-related projects.

(We’re open to this being your first senior role if you show strong technical depth and ownership.)

• Solid experience working with AI/ML models — training, fine-tuning, deploying, or building applications around them.
• Strong backend development skills, with experience in frameworks like FastAPI, Flask, or Django.
• High curiosity for data processes, and a genuine interest in making sense of complex datasets.
• Practical experience with databases such as PostgreSQL, MongoDB, or similar.
• Exposure to cloud environments (AWS, GCP, Azure) and containerization (Docker, Kubernetes) is a plus.
• High agency and self-motivation — you love taking ownership of problems and driving solutions.
• Good communication skills and a team spirit.
• Salary: Based on experience, with the opportunity for a significant increase after our next fundraising round.
• Equity Options: Expect a generous equity program, ensuring that you get a stake in the company that makes our overall success also your personal success.
• Remote Work: This is a hybrid position, offering the flexibility to work remotely with the option to use our office at Humboldt University or at K.I.E.Z. in Berlin. Some in-person attendance is required for team meetings and occasional start-up or industry events.
• Location: The hire needs to be located in Berlin or within close, physical proximity.
• Growth Opportunity: Gain deep insights into all aspects of the business and take your career to the next level. Be a part of a fast-growing start-up where you can make a real impact. We are open to this being your first senior position and to involve you in each future software development hire, potentially building you to a managerial function if desired. We are also open to you nerding out only by yourself on data for the foreseeable future.
• Supportive Culture: We promote a safe, inclusive, and supportive work environment where everyone's ideas are valued, and we avoid micro-management.
• Learning Environment: We believe in continuous learning and growth, providing a space for you to explore new technologies, methodologies, and approaches in data engineering.
