[Hiring] Senior Machine Learning Engineer @Sonatafy Technology

Role Description

• Design and build machine learning models from scratch using algorithms such as Decision Trees, K-Means, Neural Networks, and Random Forests.
• Deploy machine learning models manually using Python, ensuring scalability, reliability, and performance.
• Analyze data points such as IP addresses, locations, and user behavior to identify patterns related to spam detection and trust/safety.
• Perform feature engineering and selection to build effective machine-learning models.
• Set up and manage cloud infrastructure to deploy machine learning models without relying on managed services such as Amazon SageMaker.
• Innovate and experiment with solutions independently, taking ownership of complex problems without constant supervision.

Qualifications

• Strong understanding of machine learning algorithms, statistics, feature engineering, and optimization.
• Hands-on experience with building and deploying machine learning models using Python.
• Experience in trust and safety/spam detection, analyzing data for threat identification.
• Proficiency in setting up and managing cloud infrastructure for model deployment.
• Independent problem-solver with a creative and experimental mindset.
• Working knowledge of Natural Language Processing (NLP).
• Familiarity with LLM tooling — prompt engineering, embeddings, and vector databases, among others.

Requirements

• Machine Learning Libraries: Scikit-Learn, TensorFlow, PyTorch.
• Data Manipulation: Pandas, NumPy, NLTK, spaCy.
• Cloud Infrastructure: AWS and/or Azure, or similar cloud platforms.
• Web Frameworks for API Deployment: Django or Flask for building APIs to serve machine learning models in production.

Benefits

• Join a community of highly skilled engineers across Latin America supporting innovative U.S.-based teams.
• Be part of a fast-moving, client-first culture where your code has real-world impact.
• Competitive compensation.
• Remote-first lifestyle.
• Career growth opportunities across industries and technologies.
