Staff Machine Learning Engineer

Want to help us help others Were hiring!

GoFundMe is the worlds most powerful community for good dedicated to helping people help each other. By uniting individuals and nonprofits in one place GoFundMe makes it easy and safe for people to ask for help and support causes for themselves and each other. Together our community has raised more than $40 billion since 2010.

Join GoFundMe as our next Staff Machine Learning Engineer (Pricing). In this role you will design develop and deploy machine learning systems that power pricing and monetization programs across GoFundMe such as personalized donation and checkout experiences donation yield optimization (one-time and recurring) recurring donor LTV optimization fundraising goal suggestions and more. This role requires strong end-to-end execution and deep expertise in building production ML systems (data training online inference measurement) with rigorous experimentation and monitoring.

This is a hybrid position. Candidates considered for this role will be located in Buenos Aires Argentina.

The Job

• Own end-to-end ML systems for pricing optimization from problem framing and metric definition (e.g. donation yield conversion retention LTV) to model development launch and iteration in production.
• Design and implement backend model pipelines including feature engineering training and evaluation.
• Build low-latency real-time inferencing services including API design caching strategies model packaging and deployment on Kubernetes.
• Collaborate with teams to develop instrumentation and event pipelines to capture user and campaign activity required for training and evaluation (e.g. impression/click/submit donation amount tip amount recurring enrollment/cancellation) ensuring schema quality lineage and privacy-by-design.
• Apply causal and experimental methodologies to measure impact and avoid biased optimization including online A/B testing design guardrail metrics sequential testing considerations and counterfactual/causal approaches when needed.
• Develop optimization approaches appropriate for pricing-like problems such as uplift modeling bandits constrained optimization calibration and multi-objective tradeoffs (e.g. yield vs. donor trust short-term conversion vs. long-term retention).
• Establish ML operational excellence by implementing model observability (latency errors drift calibration business KPI deltas) automated retraining triggers rollback strategies and incident response playbooks for pricing systems.
• Partner cross-functionally with Product Engineering Design and Legal/Privacy stakeholders to translate business goals into measurable technical deliverables and ship safely.
• Mentor and set technical direction for other engineers and scientists through design reviews architecture decisions and shared best practices for production ML in monetization.
• Employ a diverse set of tools and platforms including Python AWS Databricks Docker Kubernetes FastAPI Terraform Snowflake and GitHub to develop deploy and maintain scalable and robust machine learning systems. (Full-stack experiencee.g. integrating with web clients and experimentation frameworksis a plus.)

You

• 7 years of hands-on experience building and shipping production machine learning systems with demonstrated ownership of backend services and ML pipelines in a high-availability environment.
• Strong proficiency in Python and ML libraries/frameworks such as PyTorch TensorFlow Scikit-learn plus strong software engineering fundamentals (testing code review CI/CD API design performance and reliability).
• Demonstrated experience in pricing/monetization or growth optimization domains preferred.
• Experience designing and deploying real-time model serving (sub-100ms to low-hundreds ms latency targets) including containerization scalable inference feature retrieval and safe rollout strategies (canaries shadowing backward-compatible schema evolution).
• Strong data engineering fluency: building reliable datasets and features using SQL Spark/Databricks and warehouse technologies (e.g. Snowflake) with an understanding of event semantics identity resolution and data quality controls.
• Working knowledge of experiment design and causal measurement for monetization systems including pitfalls such as selection bias interference and delayed outcomes; familiarity with uplift modeling bandits or constrained optimization is a strong plus.
• Experience implementing ML monitoring for both technical and business metrics (drift calibration segment performance latency error budgets) and operating models in production.
• Ability to break down ambiguous high-impact problems define crisp interfaces and success metrics and deliver iteratively with strong stakeholder communication.
• Strong leadership and mentoring skills and a proven ability to raise the bar on architecture engineering quality and operational rigor for ML-powered pricing systems.
• Advanced degree (Masters or Ph.D.) in Computer Science Statistics Data Science or a related technical field is preferred.
• Sense of humor is optional but appreciated.
