What You Bring

Skills and experience matter — but so does who you are. We're building a team with a Founders Mentality, and the intangibles are non-negotiable:

• Drive — You don't wait to be pointed at work. You identify what needs to happen and make it happen.
• Grit — You grind through hard problems, absorb setbacks, and come back sharper. The work isn't always clean, and you're fine with that.
• Emotional intelligence — You read rooms, build trust across functions and seniority levels, and know when to push and when to listen.
• Team-first orientation — You understand that individual wins don't mean much if the team loses. You pick up what needs picking up.
• Winner's mentality — You keep score, hold yourself to a high standard, and genuinely care about outcomes — not just activity.
• Enthusiast mindset — You get the customer because in some way you are the customer. Passion for cars, performance, or the broader enthusiast culture is a genuine differentiator here.

Education & Experience

• Currently enrolled in a Bachelor's degree program in Accounting, Finance, or a related field (sophomore standing or above preferred).
• No certifications required; completion of introductory accounting coursework (e.g., Financial Accounting, Managerial Accounting) strongly preferred.
