How to Apply

If you would like to be considered for contract work, please apply with your resume and provide a link to previous work (where applicable). Be sure to include your availability for the next 2-4 weeks so we know if you\'re keen to take on new work!

Disclaimer

Please note that if selected, you will be working as an ‘Independent Contractor’ and not as an employee at MistyWest. We have previously hired from our contractor pool, so this is a great way to get your proverbial "foot in the door" when it comes to securing a permanent gig as a Westie!

Requirements will vary depending on the specific project you are being hired for. Some projects require your physical presence in our Vancouver office and lab a few days a week/month - some are 100% remote enabled.
