Practical experience with at least one cloud provider (AWS, GCP). Strong background in working with large datasets, SQL/NoSQL databases. Ability to decompose complex problems into well-structured ML tasks. Skilled at assessing whether ML is the best approach or if a simpler solution (e.g., heuristic rules, statistical methods) would be more effective. Expertise in debugging, optimizing, and enhancing models for performance, efficiency, and interpretability. Experience maintaining ML workflows to ensure reproducibility, scalability, and operational efficiency. Excellent communication skills, capable of explaining ML concepts to both technical peers and non-technical stakeholders. Collaborative, product-focused approach within Agile, cross-functional environments. Proactive mindset with a strong sense of ownership with the ability to lead ML tasks end-to-end, from discovery and experimentation to production deployment and support.

Continuous learning mindset with awareness of current ML/AI trends, tools, and best practices. English proficiency at an Upper-Intermediate level or above.

Remote flexibility: Work where and how you work best - we trust you to deliver. Fair compensation: Competitive salary + benefits that matter (medical, learning). Ownership opportunities: See a problem worth solving? Own it. We back smart risks over bureaucratic safety. AI enhancement: We leverage AI to make you faster and stronger - complementing your abilities, not replacing them. Learning investment: English classes, professional development. Career progression: Real paths up, not just sideways shuffling.
