Advance Your Career at Planstin
Located in Southern Utah, Planstin is at the forefront of benefits administration and business services. We simplify health insurance for employers and individuals, emphasizing cost-effectiveness and excellent service in a complex market. As our company grows, we’re looking for talented individuals eager to progress in their careers.
About The Role
We are looking for a Senior Full Stack Engineer to help build out the next generation of the Planstin Membership Platform—a complex system that spans membership management, pricing engines, CRM integrations, ETL pipelines, and an evolving AWS-based microservice architecture. In this role, you’ll work directly with the founder/architect who built the current system, take ownership, anticipate problems before they surface, and propose thoughtful solutions. The right engineer must be comfortable adapting their plan when the business direction shifts. This is not a narrow feature-factory role. We need someone who can see the whole system, understand how the parts interact, and help push the architecture forward.
This position is based in St. George Utah but we'll consider full time remote and out of state for the right candidate.
