Senior AI/ML Engineer

We are looking for a Senior AI/ML Engineer with strong hands-on experience building and deploying AI solutions in real-world products. This role requires someone who can independently move from research and experimentation to implementation, evaluation and production deployment.

What we offer:

• Long-term cooperation on an international project.
• Fully remote work.
• A collaborative environment with experienced engineers.
• Private medical care.
• Multisport card.
• Flexible working arrangements.

Zakres obowiązków

• Research, design and implement AI/ML solutions addressing complex product and data challenges
• Build and integrate production-ready AI-powered features
• Explore different technical approaches, run experiments and evaluate results to identify the most effective solutions
• Develop Python-based AI/ML applications, workflows and data processing solutions
• Build prototypes and turn successful experiments into scalable, reliable production systems
• Work with LLMs, machine learning models and AI APIs as part of real product features
• Define evaluation methods and metrics to measure quality, accuracy, latency, cost and business impact
• Investigate model behaviour, identify performance issues and improve AI solutions based on real-world results
• Work closely with engineering and product teams to integrate AI capabilities into existing systems
• Take ownership of AI initiatives from initial research through implementation, deployment and continuous improvement
