Staff Machine Learning Engineer role focused on building scalable ML systems in growth and consumer engagement domains, with involvement in DeFi and NFT wallet ecosystems.
Обязанности
- Define the long-term technical roadmap for Growth and Engagement ML systems, ensuring scalability, reliability, and measurable business impact
- Architect and deploy production-grade ML pipelines and real-time decisioning systems that power personalization, notification dispatch, and onboarding flows
- Evaluate and integrate cutting-edge ML techniques, including multi-armed bandits, reinforcement learning, LLMs for content generation, and advanced graph neural networks
- Design, train, and validate sophisticated models targeting user lifecycle stages: propensity to churn, lifetime value (LTV) forecasting, next-best-action, and lookalike modeling
- Build and optimize recommendation engines and semantic search systems to surface highly relevant content, products, or features to users
- Establish robust experimentation frameworks (advanced A/B testing, causal inference, and multi-variate testing) to rigorously validate model variants in production
- Partner with Product and Growth marketing teams to translate high-level business hypotheses into precise, actionable machine learning problems
- Mentor and coach senior engineers across the data and ML organizations, fostering a culture of technical excellence and continuous learning
- Advocate for ML engineering best practices, including model monitoring, feature store utilization, reproducible training pipelines, and data governance
Требования
- 8+ years of professional experience in machine learning engineering, data science, or software engineering, with at least 3+ years in a Staff, Principal, or Tech Lead capacity
- Proven track record of building and scaling ML systems specifically within growth, marketing tech, recommendation engines, or consumer engagement domains
- Extensive experience with large-scale data processing and distributed computing
- Languages: Expert-level Python, Scala, or Java
- ML Frameworks: PyTorch, TensorFlow, JAX, or XGBoost
- Data & MLOps Infrastructure: Spark, Flink, Kafka, Snowflake/BigQuery, Ray, Kubeflow, MLflow, or SageMaker
- Experimentation: Deep understanding of causal inference, uplift modeling, and robust statistical testing methodologies
- Business Acumen: Ability to directly connect algorithmic improvements to top-line growth metrics (e.g., MAU/DAU, conversion rates, retention curves)
- Communication: Exceptional ability to explain highly complex technical architectures and algorithmic choices to non-technical stakeholders and executives
- Wallets play a pivotal role: Wallets are responsible for on-boarding new users into crypto, and can make or break the user experience
- We are moving to a multi-chain world: New blockchains and scaling solutions are coming online and gaining traction, but are lacking decent wallets and bridges
- DeFi & NFTs are exploding : Interest in DeFi and NFTs has exploded, yet they are still an after-thought in existing wallets
