About Mobilize


Founded by two entrepreneurs, Mobilize is a fast-paced technology and communications company. We have entered into our most extensive growth phase and are expanding our team to align with our big VISION.


We believe in working hard and having fun! We do company retreats off-site so the team can get to experience each other in a “non-office” environment. Celebrating each other's achievements is one of our favorite things to do.


Our team comes from many different backgrounds and we are incredibly passionate and committed to diversity in all areas of our team. That commitment goes beyond the hiring stage into the day-to-day active work it takes to keep an inclusive space. As a business, internal and external, we chose to be on the side of providing solutions, not problems. We look for experience, education, training, self-taught skills, and problem-solving magical unicorns. We want people who are hungry for life, their career, and what contributions they make to the world. We’ve taken the stance of, if you see something, say something, there is never a day to be on the wrong side of history.


Mobilize has established a unique working environment that allows team members to excel and climb their own career growth trajectories. We are committed to providing our team with fun and exciting challenges and opportunities that will put them at the forefront of changing what is possible with technology.


Job Description:


The Senior Full Stack Developer is an experienced software developer that will provide their expertise to our growing software development team and helps scale our products for our clients. This team member applies and oversees development principles, techniques and scientific methods in IT. Develops and maintains software per company’s requirements with assistance from mid-level and lead developers.

Key aspects of this position are to work with the VP of Engineering and the Lead Developer through all phases of the software development cycle and serve as a mentor to mid-level developers.


Need To Knows:

  • Location: Remote Work & Denver, Colorado

  • Salary: $130,000-$160,000

  • Time Commitment: 9AM-5PM MST (Full-Time) Monday – Friday

  • Company Provided Equipment

  • Experience Required: 5 years of each backend RESTful API, SQL database, and frontend development

Day to Day:


Let’s get down to brass tacks, what is it REALLY like to work for Mobilize? We like to think about things a little differently and put culture first. While you’ll see a lot of the same patterns at other companies (agile, sprint meetings, etc); at Mobilize people always come first and we regularly open up our meetings talking about learnings, our weekends, and our goals! Being on a small (but growing!) agile development team allows us to get to know each other, build relationships, and really get into the trenches together. Our wins are shared, and we’re always open and transparent about what we as a team need to improve on. As a senior on the team, you’ll split your time between crushing code, helping level up the rest of the team on their code/PRs, and working with our chief architect and PM to define and roadmap the future of VISION. Join us!
