We're looking for a Principal Business Analyst to shape how new customers find Mission Lane, reporting to the Director of Growth. You will decide where and how we spend so more people find Mission Lane when they are ready for that next step. You'll manage test investments at a meaningful scale, weighing the credit risk on each one, and you’ll run the day-to-day strategy and relationship with one of our biggest affiliate partners. Responsibilities: - Design and size acquisition tests: Whether that's a new channel, a new customer segment, or a new offer. - Analyze credit risk before a launch: Determine what the downside looks like if a test underperforms. - Own third-party relationships: Manage the day-to-day operations of external partnerships. - Optimize performance: Work with acquisition partners to keep channels performing, managing placement, pricing, and data terms. - Monitor live tests: Track performance in real-time to manage risk and budget. - Partner cross-functionally: Work alongside engineering, product, and marketing to launch tests. - Communicate with executives: Share strategy and results directly with senior leadership. Minimum qualifications: - 2+ years of experience in a highly analytical role. - Experience in the financial services industry. - A bachelor's or master's degree in economics, finance, engineering, mathematics, or a similarly quantitative field. - A track record of solving open-ended business problems: framing the question, forming a hypothesis, working through the data, and defending recommendations. - Comfort working in SQL, Python, or similar tools for data analysis. - Ability to travel ~4–6+ times per year for in-person collaboration. Preferred qualifications: - Experience working with credit cards or other consumer lending products. - Experience helping scale a business in a fast-moving startup environment. - Strong SQL or Python skills. - Experience using AI coding assistants (Claude, Codex, Gemini, Cursor, etc.).
