About The Right Team Member

You enjoy both sides of machine learning: building robust ML infrastructure to make our data scientists' jobs easier as well as diving into the details of ML models directly. You know the best software is created through collaboration and iteration and you’re looking for the right opportunity, and the right team, to expand your experience. You seek feedback because it has the ability to turn good work into great work. You like to ship software early and often, you value simplicity and strive to eliminate unnecessary complexity.

ClassPass is looking for senior and mid level Machine Learning Software Engineers. Our engineers are the brains behind some of the fitness industry’s biggest breakthroughs. These teams are constantly innovating and striving to create a better product for our users and drive more revenue to our studio partners.

At ClassPass we value people who are intellectually curious, who are pragmatic not dogmatic, and people who care about our product, their teammates, and their own personal growth. We are faced with an interesting set of technical challenges and we believe in giving our engineers the autonomy to go and solve them. Much of our team come from non-traditional computing backgrounds; we know that by bringing together a diverse set of voices we’ll be able to build a better product, and a better company. We care less about what languages or frameworks you know, and care more that you are excited to produce high-quality code and be constantly learning. Our engineers work in cross-functional teams that are focused on impact, and movement between teams is encouraged. We work very closely with our brilliant product team to deliver a world class user experience, and ultimately to empower our users to live their fullest, healthiest lives.

Key Responsibilities

  • Collaborate closely with Product and Data Science teams to iterate on the design, implementation and deployment of data products
  • Build and manage machine learning systems and applications
  • Understand reliability and performance, and proactively find and address issues to build software at scale
  • Write clear and concise technical design documents and gather feedback from your team and the broader engineering organization
  • Provide leadership and mentorship for junior engineers through code reviews and technical discussions
  • Seek different perspectives, and solicit honest feedback
  • Take delight in delighting our users
  • Care about our studio partners and want to help them grow their business

Skills & Experience

  • Proficiency with Java, Kotlin, or Python
  • Experience in machine learning, data engineering, deep learning, search, natural language processing, data science, or computer vision
  • Strong analytical and problem solving skills
  • Excellent written and verbal communication skills

Nice to Have

  • Experience with some standard machine learning tools: Spark, Flink, Tensorflow, PyTorch, Theano, HDFS, Hive, or Athena
  • Understand reliability and microservice monitoring best practices
