Sr. Full Stack Engineer (SaaS Applications)

Sophia Learning is an innovative education platform that helps students save time and money by offering low-cost, self-paced online courses designed to transfer for college credit. Our mission is to make higher education more accessible by delivering flexible, high-quality learning experiences that support students at every stage of their educational journey.

As a Senior Full Stack Engineer, you will play a critical role in designing, building, and supporting the mission-critical applications that power the Sophia learning platform. You will take ownership of technical decisions, mentor other engineers, and collaborate closely with product and business stakeholders — your internal clients — to translate complex requirements into scalable, reliable solutions.

• Provide level 3 production support for enterprise applications after release
• Mentor and elevate other engineers through code reviews, pairing, and technical guidance
• Participate in the continuous evolution of engineering standards, development workflows, and system reliability
• Help embrace and mature our agentic software development lifecycle — applying AI coding agents and AI-assisted workflows to build efficiently, and bringing curiosity and enthusiasm for integrating AI-powered features into the platform
