Machine Learning Engineer

Vancouver, British Columbia, Canada expand job description ↓


We believe that video is the most powerful tool for storytelling, but not everyone has the skills to produce videos, and so we built the world’s smartest video creator using A.I. to solve this problem.

We launched Lumen5 in early 2017 and the platform rapidly grew to service over 200,000 users within two years. Our customers include many notable brands such as Forbes, Greenpeace, Economist, LinkedIn, and hundreds more. Our company is fully bootstrapped and through the hard work of our all-star team, we grew to become a multimillion dollar success without any investor funding.

Recently, Lumen5 won the Fundica Roadshow and was recognized for being one of the fastest growing startups across all of Canada. We now have our sights set on growing our users into the millions and we’re looking for like-minded individuals to join us in elevating Lumen5 to the next level.


We’re working on some very interesting technical challenges using video, NLP, and machine learning, which means we’re hiring the brightest developers.

We’re looking for a machine learning engineer with a breadth of experience, seeking a new challenge - someone who’s not afraid to think big and propose radical changes, nor of sailing the gradient sea in search of new hyperparameters.

  • Brainstorm new approaches to providing better recommendations to users (media, storyboard, and scene-composition recommendations) by leveraging our internal dataset
  • Work as part of a small, high-velocity team - break down information silos and switch hats if necessary
  • Write high-quality, maintainable, and scalable code
  • Collaborate with other developers and designers to take features all the way from ideas to something thousands of people use daily


  • BS/MS/PhD in Computer Science or related field
  • 3+ years of professional experience
  • Proven success taking ML models from drawing board to production
  • Experience working with modern ML frameworks such as Tensorflow or PyTorch
  • Experience with supervised and unsupervised ML for regression, classification, and clustering
  • Familiarity with search ranking and information retrieval
  • Familiarity with topic modeling and natural language processing
  • Familiarity with collaborative filtering and recommender systems
  • Ability to communicate ideas concisely and engagingly to technical and non-technical audiences
