We seek candidates who can communicate fluently with team members, as well as with clients and managers, to extract product requirements and define a development path with accurate time estimates. We are looking for developers who demonstrate curiosity and a strong desire to learn and improve, with a high level of self-direction and motivation.

Minimum requirements - Backend: Strong experience with Python | NodeJS | TypeScrypt - Frontend: Strong experience with React based web development - Client management and product management experience - Strong communication skills - Available during Eastern working hours (10am - 5pm EST, flexible) - Based in Canada Nice-to-have skills - Experience with native or mobile development (e.g. iOS/Android/React Native/etc.) - Experience with MLOps, data storage solutions, and cloud platforms - Experience with Rust or crypto - Familiarity with large-scale data processing and distributed computing frameworks - Knowledge of machine learning principles and algorithms - Strong background in mathematics - Located in or near Montréal Application Process Our application process is easy and transparent: - 15min: Take an untimed coding test and access the application form upon passing. - 45min: Non-coding conversational interview Chat with Ana (no whiteboarding or quizzing theory/architecture/etc) - 2-6 hr: Small untimed take-home project See https://docs.monadical.com/s/monadical-study-guide for more details. - 60 min: Pairing interview: Add a feature to take-home project with a lead developer First 10 min: Discuss your take-home project and the current state of their code. Next 10 min: Have you step into the shoes of a product manager and discuss potential features to add to their project. Frame it as if it’s a client project and have you explain your thought process when gathering requirements, prioritizing tickets, delegating, and making time estimates. Last 40-60 min: Pair on adding a feature to the codebase together. This interview is to gauge the experience of working together on a technical task, not to measure raw coding speed. We’re more impressed by people who talk clearly through their thought process and code deliberately, than those who try to add as many features as possible in a short time. Treat the task of adding a feature as if it were an un-timed take-home task, and focus on explaining your decisions, more than sheer lines-of-code output during the interview. We’ve all had interview jitters, so if the feature was not completed during pairing or if you feel the interview wasn’t a good representation of your abilities, you’re welcome to push further commits up to 24 hours afterward with a short description of the changes made, and we’ll include it with equal weight when evaluating the codebase. - 60min: Pairing interview: same structure as above, pairing with another lead developer The whole process usually takes 2-3 weeks depending on the applicant pipeline and response times. More details on the application process (along with tips and tricks) can be found in our Monadical Study Guide.
