About The Position

SET SEG is looking for a Senior Software Developer that will be responsible for developing and supporting data‑driven applications, integrations, and pipelines using modern Microsoft and open‑source technologies.

The position contributes to continuous improvement of development practices, tooling, and emerging initiatives such as automation and AI‑enabled solutions. WHO WE ARE School Employers Trust (SET) is a non-profit company that was created after a monumental shift in school funding happened in 1965. SET, which began in 1971, served as an employee benefits association focused on offering comprehensive and affordable employee benefit solutions to Michigan public schools and their employees. Two years later, its partner organization School Employers Group (SEG) was formed to administer compensation and fringe benefits for SET. As schools were faced with more challenges related to insurance, SEG evolved and grew into a company that provides workers’ compensation and property/casualty services for Michigan public schools. Today, SET SEG continues to expand and find creative ways to meet the specialized needs of its members. This, coupled with superior member experience, is why SET SEG has maintained its position as an industry leader in the school insurance market. We value those who proactively solve challenges, simplify the complex, thrive in a fast-paced setting, have a customer-first mentality, and seek a collaborative and inclusive work environment. We offer 100% employer paid insurance (medical, dental, and vision), Paid Time off (PTO), and paid parental leave. Our passion is delivering peace of mind to Michigan public schools, and we look for team members who are motivated by our cause. To learn more, visit: https://setseg.org.
