Hybrid Senior Python Developer – Algorithms, Data na Bonfy.AI

At Bonfy.AI, we’re building trustworthy AI systems that transform how people and organizations work. We’re looking for a Senior Python Developer who thrives on turning ideas into production-ready software, owns products end-to-end, and loves solving algorithmic challenges.

This is not an infrastructure or platform role, and it’s not a data science seat. Instead, it’s for a developer with deep Python and backend engineering skills who wants to build products from inception to launch — with the opportunity to work directly with AI models and help shape how they’re applied in practice.

What You’ll Do

• Design, implement, and scale backend systems in Python that power Bonfy’s AI-driven products.
• Build and optimize algorithms for data processing, analysis, and real-time decision-making.
• Develop and manage APIs, integrations, and production services that go beyond “just pipelines.”
• Work hands-on with ML/AI models (training, fine-tuning, or integration) to extend Bonfy’s AI edge.
• Own the full lifecycle of features — from prototype to deployment to ongoing evolution.
• Collaborate closely with ML engineers, product managers, and researchers to bring intelligent systems to market.

What We’re Looking For

• 5+ years of professional backend development experience, with Python as a core language.
• Proven ability to design and ship production-grade software at scale.
• Strong algorithmic and data-handling skills; comfort with complexity and performance optimization.
• Experience building SaaS products, APIs, or data-intensive systems.
• Demonstrated interest in working with ML/AI models (integration, experimentation, or applied use cases).
• A builder’s mindset: end-to-end ownership, product intuition, and focus on impact.

Nice to Have

• Familiarity with modern Python frameworks (FastAPI, Flask, Django).
• Experience with databases (SQL and NoSQL) and cloud platforms (AWS/GCP/Azure).
• Background working with ML APIs, transformers, or other applied AI tools.

Why Bonfy.AI?

You’ll be joining a small, high-impact team at the frontier of trustworthy AI. This role gives you a chance to own real products — not just features or pipelines — and to directly contribute to how AI models are developed and applied.
