• 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 exempt under the Fair Labor Standards Act (FLSA) and applicable state wage-and-hour laws.
