Join us

Sr. Full Stack Engineer

We are looking for world-class engineers to help us develop a system that will serve as the main interface to our machine learning platform. The goal of this system is to help in all stages of model development, from feature engineering all the way to production monitoring.

Data Engineer, Machine Learning

Robust, trustworthy, and efficient data system is crucial for developing and deploying ML models in production. In addition to handling the complexity of massive data sources, ML data system also needs to provide strong support for data science specific tasks.

Machine Learning Scientist

In this role you will research, develop, and apply new techniques in the intersection of deep learning and personalization to further advance our industry leading product. We’re looking for someone with a PhD in Computer Science, Statistics, Operations Research, Mathematics or a related field.

Our team is growing fast

We’re always looking for ambitious, execution-oriented people. Submit your CV to careers@layer6.ai and let’s chat.

Our hiring process



Start by submitting your CV. If your credentials meet the requirements for the role, we’ll schedule an in-person interview at our MaRS offices in downtown Toronto.


Technical test

Your first interview will be conducted with the appropriate tech lead. You will complete three stages (Math, Coding and ML) of technical testing to assess your relevant problem solving abilities.


Final interview

Following the technical interview, you will meet with one of our founders to discuss your previous work/school experience and your aspirations in machine learning.


Receive offer

Only the most technically accomplished candidates with a strong culture fit will be offered employment packages.

Technical test sample questions

Coding Question: Implement a function to compute the number of occurrences of a digit k in all numbers between a and b where a >=0 and b >= a. Estimate the runtime of your function. You can use Java, C++, Python or Scala.

Math Question #1: Write a function sample_x( ) to draw independent samples of a random variable with probability density function

Assume you have a function RNG( ) that returns independent floats uniformly distributed in [0,1]. Can you find a way of doing this that runs in a deterministic amount of time?

Math Question #2: Consider the loss function L(x, y) = ½ ( ax² + by² ). Here x and y are the parameters, and a and b are positive constants. For what values of the learning rate will gradient descent converge to the minimum?
