At Mastery our goal is to build the next generation of technologies to allow large brokers, 3PL’s, and shippers to benefit from the progress of technology and connectivity. Our brokerage application targets large, distributed brokerages and 3PL’s, with follow-on shipper TMS available in the future.

Our team has the knowledge to make an impact, and we’re looking for serious dev talent to help. We need people who are flexible problem solvers and who know how to communicate their solutions. In this role, you will collaborate with a small team to understand user and market needs, participate in architectural design, and build our responsive web application.

Mastery is dedicated to providing a great working environment by challenging our team members while being respectful of your time and the needs of your personal life. That’s why we encourage time exploring innovation ideas alongside more standard daily tasks. We require employees to schedule at least one week off every four months.
