[Remote] Senior ML-Engineer

Note: The job is a remote job and is open to candidates in USA. Fundraise Up is a global fundraising platform that enhances the donation process for nonprofits. They are seeking a Senior ML Engineer to develop and deploy machine learning solutions across various business areas and collaborate with multiple product teams.

Responsibilities

• Develop and deploy ML solutions across different business areas using tabular data (uplift models, recommender systems). We are also actively developing projects that will involve e-commerce mechanics
• Select the most appropriate ML/LLM approaches or propose alternative solutions
• Build end-to-end ML solutions: data preparation, training, API development, and monitoring
• Design prompts and LLM API-based pipelines for specific product tasks: classification, content generation, and response quality evaluation

Skills

• 5+ years of ML/DS experience solving real product problems
• Strong expertise in ML and mathematical statistics: solid knowledge of classical algorithms (especially gradient boosting); NLP knowledge is a plus
• Metrics-driven mindset: ability to connect ML metrics (ROC-AUC, F1, RMSE) with business metrics (CR, LTV)
• Strong engineering culture: confident in Python with a product-oriented approach to development; we value clean code, knowledge of design patterns, and solid engineering practices
• Data skills: advanced SQL; ability to independently and efficiently build complex datasets in ClickHouse and work with MongoDB
• MLOps understanding: hands-on experience with experiment tracking tools and understanding of production workflows (Docker, Git, CI/CD)
• Autonomy: ability to break down problems, choose the right tech stack (or justify a non-ML solution), and deliver to production
• At Fundraise Up, AI is a default tool, not an experimental one. We expect every team member to actively use AI in their day-to-day work, identify where AI can change the shape of problems in their function, and grow their fluency as the tools evolve. You should already be using AI meaningfully in your work and understand where it adds value and how it can improve the way you operate
