Customer Success Lead

Lightspark is creating the Money Grid, modern, open financial infrastructure that makes payments accessible, affordable, and instant for businesses and users worldwide. We're challenging the status quo, updating the current system, and empowering our partners to build better solutions. Together, we're building the most advanced financial infrastructure, open, instant, and global, inspiring a future where anyone, anywhere can access the full potential of digital money. As a Customer Success Lead, you will own and grow some of Lightspark’s most strategic customer relationships. You will become an expert in the Lightspark product ecosystem, evangelize Lightspark products, and ensure customers are successful from the onboarding process to post-launch and beyond. You bring sharp commercial judgment, deep product curiosity, analytical rigor, and are hungry to grow in a fast-paced environment. Based in Los Angeles at Lightspark headquarters, this is a high-ownership role at the intersection of enterprise customers, product, engineering, and revenue. WHAT YOU’LL BE DOING End-to-End Account Ownership: Manage a targeted portfolio of strategic accounts. Serve as the primary owner from initial onboarding and launch through ongoing expansion, deeply understanding each customer’s business roadmap. Drive Account Growth: Establish and execute the expansion thesis for each customer relationship. Build compelling business cases in close collaboration with customers to ensure strong alignment, clear value, and shared conviction. Executive Relationship Management: Act as the trusted first point of contact for anything touching money movement. Earn this strategic positioning by delivering substantive value and insight, rather than superficial networking. Product Feedback Loop: Act as an opinionated advocate for customer needs by translating their feedback into sharp, actionable inputs for Product and Engineering. Strategic Business Reviews: Design and deliver numbers-first, highly strategic business reviews that customers genuinely value and can confidently share with their own leadership teams. WHAT WE ARE LOOKING FOR Experience: 5+ years in high impact customer success, strategic account management, or enterprise partnerships at a fast-moving, deeply technical company (ideally fintech, payments, or complex B2B SaaS). You have owned outcomes, not activities, and you can describe the difference in concrete terms. Data-Driven Strategy Mindset: An analytical, systems-level thinker who relies heavily on data and financial metrics to prove value and drive customer satisfaction. Executive Communication: Exceptional ability to command a room, navigate highly complex multi-stakeholder environments, and seamlessly translate deeply technical product capabilities into tangible business value. High Leverage with AI: An AI-native builder who uses frontier tools daily to multiply individual output, bringing a sharp, seasoned point of view on where AI provides genuine utility versus where it simply adds noise. Technical & Product Fluency: High comfort level collaborating with product and engineering leaders to systematically evaluate which customer requests warrant architectural changes. Location: Ability to work onsite at our HQ office in Los Angeles, CA . Nice to have: A background in payments, fintech or crypto. Experience as the first or second CS hire at a company that scaled past you. A network across fintechs, exchanges, neobanks, treasury, and remittance — the spaces our customers live in. Lightspark is on a mission to build the future of open, instant, and global financial infrastructure making payments accessible and affordable for everyone, everywhere. We're committed to creating a more inclusive and diverse workplace to reflect the customers we serve. We welcome interest from individuals of all backgrounds and levels of experience who share our mission. We do not discriminate based on race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, disability status, or other applicable legally protected characteristics. We will consider for employment qualified applicants with criminal histories in a manner consistent with the requirements of the State of California Fair Chance Initiative for Hiring.
