Description

Senior Full-Stack Developer
Summary
Since 1979, TxMQ has been building, integrating, managing, supporting and securing critical business systems and data for large and mid-market enterprise customers. TxMQ's Disruptive Technologies Group (DTG) was established in 2017 to provide consulting services and development capabilities to our customers in emerging technologies. DTG currently has a heavy focus on implementing solutions that leverage blockchain or distributed ledger technology. DTG is an engaging, fast-paced environment where technological change is expected and embraced. Our developers have a unique opportunity to work with cutting-edge emerging technologies, each with the potential to explode into the next big thing.
Senior Full-Stack Developers work in small teams with other client- and server-side developers to build out solutions for our customers. Our development teams are led by a Technical Lead, who has primary responsibility for the delivery of their individual projects. Senior developers are expected to demonstrate consulting skills, and to be comfortable engaging directly with customers. All of our developers are expected to be good communicators, to manage their time effectively, and to have a passion for what they do. An eagerness and ability to quickly learn new approaches and technologies is a must-have.
