Junior Machine Learning Engineer (Trust and Safety...

Job description


Yelp engineering culture is driven by our values: we’re a cooperative team that values individual authenticity and encourages creative solutions to problems. All new engineers deploy working code their first week, and we strive to broaden individual impact with support from managers, mentors, and teams. At the end of the day, we’re all about helping our users, growing as engineers, and having fun in a collaborative environment.

Are you intrigued by data? Yelp has hundreds of millions of pieces of user-contributed content, millions of users and business listings, and hundreds of thousands of advertising customers – and all of these numbers are constantly growing. Making sense of this data, deducing relationships between variables, and figuring out different interactions is hard work, but these insights are hugely impactful to Yelp’s business.

The Trust & Safety team at Yelp focuses on surfacing high-quality content that reflects authentic experiences generated by real Yelpers who are engaged with the community. We invest heavily in ML models and infrastructure to detect and understand content spam on our platform.

As an engineer on our team, you’d be helping our users, every day, to make trustworthy connections with great local businesses, by deciding where to eat, which mover to call, or best places to visit in a new city. Yelp’s mission of connecting people with great local businesses requires the use of cutting-edge Machine Learning (ML) and Artificial Intelligence (AI) to scale across a vast and diverse base of users and businesses spanning various geographical locations. As an ML engineer, you will have the opportunity to foster these connections across millions of users and business listings using cutting-edge industry tools such as neural networks (NNs), large language models (LLMs), and traditional ML methods like XGBoost or linear models.

This opportunity requires you to be located in the Republic of Ireland. We’d love to have you apply, even if you don’t feel you meet every single requirement in this posting. At Yelp, we’re looking for great people, not just those who simply check off all the boxes.

  • Experience developing and productionizing machine learning models, including their supported data pipeline.
  • Strong coding skills in Python or equivalent
  • Experience with Machine Learning using packages such as TensorFlow, Spark MLib, XGBoost, sklearn, etc.
  • Solid understanding of engineering and infrastructure best practices.
  • The curiosity to uncover promising solutions to new problems, and the persistence to carry your ideas through to an end goal.

What You'll Get

  • Full responsibility for projects from day one, a collaborative team, and a dynamic work environment.
  • Competitive salary, a pension scheme, and an optional employee stock purchase plan.
  • 25 days paid holiday (rising to 29 with service), plus one floating holiday.
