Job Title: Senior Python Developer

Location: Berlin, Germany (Hybrid position)

Type: Full-Time

Entry Date: Immediately

Company Description: Talonic is a dynamic and innovative AI start-up dedicated to making data and analytics accessible to everyone. We are looking for a passionate and experienced Sales Manager to join our growing team, who will play a pivotal role in shaping our sales funnels. Talonic is backed by the Humboldt University of Berlin, K.I.E.Z., Science & Startups, NVidia Inception, Microsoft and more.

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:

• Own and evolve our largely Python-based codebase (FastAPI-based, asynchronous pipelines, LLM integrations, OCR, sandboxed execution).
• Balance engineering rigor (testing, code reviews, CI/CD) with practical problem-solving across a variety of domains.
• Guide junior developers through code reviews, mentoring, and knowledge-sharing.
• Architect and maintain pipelines that run both on-premise and in the cloud under varying hardware constraints.
• Collaborate with product and business stakeholders to translate requirements into maintainable, scalable solutions.
• Research, prototype, and implement unorthodox solutions when the best approach isn’t obvious (e.g., parsing quirky file formats, adapting to regulatory/business needs).

Must-Haves:

• Strong professional experience designing and delivering complex applications, ideally across different domains.
• Deep knowledge of Python, from async programming and FastAPI to performance optimization and maintainable code structure.
• Curiosity and versatility: ability to quickly learn unfamiliar domains (files, models, business rules, etc.).
• Some Linux/DevOps/Cloud experience - comfortable deploying, debugging, and tuning systems in production.
• Team leadership or mentoring experience with junior developers.
• Pragmatic understanding of applied AI/ML concepts, particularly LLM usage and structured output.

Nice-to-haves:

• Experience with OCR, object detection models (YOLO or similar), or other ML integrations
• Familiarity with common business operations
• Experience building web applications, REST-APIs, Enterprise solutions
• Contributions to open-source or a portfolio of exploratory side projects.
• You don't trust the hype, but you're not refusing to use an IDE either.

Benefits:

• Salary: Based on experience, with the opportunity for a significant increase after our next fundraising round.
• 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.
• 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.
