As a Technical Support Engineer, you will be the technical problem-solving expert for our customers across healthcare, higher education, and corporate environments.

This job description is not designed to cover or contain a comprehensive listing of activities, duties, or responsibilities. Duties may be added, removed, or modified at any time in accordance with business needs and applicable law.

This role may require occasional evening or weekend work to support customers in different time zones or during critical system implementations.

Humble: The right leaders for Illumia don't need to own the spotlight — they share credit, define success collectively, and are quick to elevate the contributions of others. This is a company that still writes its story. The leaders who thrive here find energy in building something together, not in being recognized as the smartest person in the room.

Hungry: We are not looking for caretakers. We are looking for leaders who are restless about what's possible, self-motivated to close the gap between where we are today and where we need to be, and who are already thinking about the next opportunity before anyone asks.

Smart: At Illumia, our leaders must operate across a complex, distributed organization spanning multiple product lines, two legacy cultures, and thousands of customers with competing priorities. Technical skills matter, but the ability to read a room, build trust across functions, and bring people along is what separates a great leader from one who burns the organization out.

This position is classified as non-exempt under the Fair Labor Standards Act (FLSA) and applicable state wage-and-hour laws.

Flexible time off to include paid holidays and volunteer time.

Robust health, dental, and vision insurance plans on your first day of employment

Employer-paid life insurance/AD&D/short-term and long-term disability insurance

Comprehensive employee assistance program (EAP)

Flexible spending account (FSA) or health savings account (HSA)

Matched 401(k)

Employee stock purchase plan

Base salary offers for this position may vary based on factors such as location, skills, and relevant experience. Some positions may include additional compensation in the form of bonus, equity, or commissions.
