About your tasks:
- Work with colleagues from our Data & AI department and collaborate closely with product managers, engineers, and business stakeholders.
- Provide technical leadership for our Recommendations product, helping define the architecture, technical direction, and longer-term evolution of our machine learning systems.
- Design, build, and operate machine learning systems for recommendation use cases such as candidate generation, ranking, personalization, product discovery, and recommendation optimization.
- Translate ambiguous business and product requirements into scalable ML solutions, balancing model quality, latency, reliability, scalability, and maintainability.
- Lead technical design and architectural decisions for complex ML initiatives and help the team navigate trade-offs across modeling, data, infrastructure, and product requirements.
- Develop robust ML pipelines for feature engineering, training, evaluation, deployment, monitoring, and continuous model improvement.
- Bring models into production using our cloud-based stack and ensure they are reliable, observable, and maintainable over time.
- Identify technical risks, gaps, and opportunities across the recommendation stack and drive improvements that increase the effectiveness and scalability of the overall system.
- Communicate technical decisions, assumptions, limitations, and uncertainty clearly to product, engineering, and business stakeholders.
- Raise the technical bar through design reviews, mentoring, knowledge sharing, and by establishing ML engineering standards and best practices within and beyond the team.
About you:
- You have extensive hands-on experience as a Machine Learning Engineer, ML-focused Software Engineer, or Data Scientist with strong engineering experience.
- You have built and operated production-grade machine learning systems, pipelines, or model-based products and have taken technical ownership of complex ML systems.
- You have strong experience working with recommender systems, ranking, personalization, or related product discovery systems.
- You have demonstrated technical leadership, influencing architecture, engineering practices, and technical direction beyond your own individual contributions.
- You are comfortable working with complex data and understand common ML failure modes such as data leakage, feedback loops, distribution shifts, and misleading offline metrics.
- You can reason about system-level trade-offs and make pragmatic technical decisions across model quality, latency, reliability, scalability, and maintainability.
- You enjoy working close to the business and can explain complex technical topics and trade-offs clearly to technical and non-technical stakeholders.
- You take ownership of ambiguous, cross-cutting problems, work proactively, and can drive technical initiatives across team boundaries.
- You value collaboration, give and receive feedback openly, and actively help other engineers grow through mentoring and technical guidance.
