About the role
- Senior Machine Learning Engineer building the foundation for Circle's recommendation engine and discovery marketplace. Aiming to enhance users' goals through innovative ML systems.
Responsibilities
- Help build the discovery feed — the core recommendations engine that powers how consumers find creators, products, and communities that help them grow.
- Partnering closely with Circle’s CEO and co-founders to execute on a vision that redefines discovery in the creator economy.
- Designing, implementing, and iterating on large-scale ML systems — from embeddings and ranking models to experimentation frameworks — to reach product/market fit.
- Using data, experimentation, and engineering intuition to make fast, high-quality decisions that unlock transformational consumer experiences.
- Obsessing over the craft, quality, and performance of the algorithms that turn Circle Discover into a household name.
Requirements
- 5+ years of hands-on software engineering experience, with at least 2+ years focused on machine learning, data, or recommendation systems.
- Experience building or scaling feeds, ranking systems, or large-scale consumer-facing ML products.
- Strong proficiency in backend and data engineering skills — from system design to productionizing ML models.
- Deep understanding of consumer app dynamics and what drives product/market fit in discovery and recommendation experiences.
- The curiosity and drive to learn fast, experiment aggressively, and thrive in a highly dynamic environment.
- Comfortable in a fast-paced environment with a certain level of ambiguity, especially when learning and picking up new technologies when projects require it.
- Strong alignment with our values, find our values on our career page if you haven’t read up on them yet.
