Senior Remote Nodejs Developer Jobs in Orem, UT (NOW HIRING)

We are seeking a highly experienced Senior / Principal Software Development Engineer to support a large-scale Healthcare Communication Training Platform built on a modern MERN-stack architecture hosted within AWS. This is a hands-on engineering and technical leadership role focused on platform stabilization, architectural improvement, feature development, and long-term scalability.

The ideal candidate brings deep expertise across full-stack JavaScript development, cloud-native AWS environments, and modern application architecture, while also being comfortable operating within complex, fast-moving client environments. This individual will work closely with technical leadership, project management, QA, DevOps, and business stakeholders to drive both ongoing maintenance efforts and new platform enhancements.

• Participate in sprint planning, backlog grooming, architecture discussions, and code reviews

• Create and maintain technical documentation, architecture diagrams, and environment configuration documentation

• Collaborate cross-functionally with Product, QA, DevOps, PMs, and stakeholders

• Identify technical risks and proactively propose mitigation strategies

• Mentor and support junior and mid-level engineers
