About Us
Mastery Logistics Systems is reimagining the technology that moves goods from one place to another. We are building an intuitive, efficient, comprehensive solution that brings cutting edge technology, the power of data and AI, and user experience to the forefront. For those that know the jargon and the logistics industry, we are building the next generation of technologies to allow large brokers, 3PL’s, and shippers to benefit from the progress of technology and connectivity. Our initial offering - a TMS built for freight brokerages - targets large, distributed brokerages and 3PL’s, with follow-on shipper TMS available in the future. If you don’t know the industry (yet!), that’s cool – we want your voice and perspective to help us break out of established patterns and truly innovate. 
The problems in this industry are big and exciting! There’s also a lot of low hanging fruit where other industries and types of applications have found solid solutions. We are tackling everything from fast and efficient data input (Natural Language Processing? Voice? Better forms?) to ingesting large amounts of data and applying AI to looking at blockchain to securely digitize paperwork. If you are passionate about humanizing an industry, automating in innovative ways, building for quality and scale, helping make people's lives easier, touching every part of our economy or all of the above then this is the place for you. 
Mastery Logistics Systems is committed to providing a great, inclusive 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 innovative ideas alongside more standard daily tasks. We have a 4-day work week (with 1 Friday a month reserved for company meetings) and require employees to schedule at least one week off every four months. 
Our team has the domain knowledge and connections to make an impact, and we’re looking for experienced and thoughtful people to help. We need people who are flexible problem solvers, collaborate consistently and know how to communicate their solutions well. We are small and nimble, and each member of the team can make a tremendous impact both technically and culturally. While a start-up, we are well-funded, have an initial paying customer with which to test and launch, and are founded by top experts and veterans in the logistics industry. Join us and help make something great.
