Job Summary
What You’ll Be Doing
📍Design and ship the KAST Partner API suite from the ground up, enabling features like SSO, balance queries, transaction history, and card status retrieval. 📍Develop a streamlined KYC/AML process by defining the integration for ingesting partner identity tokens (e.g., Sumsub). 📍Write crystal-clear, detailed API specifications and work hand-in-hand with a dedicated engineering team to manage the development lifecycle. 📍Create excellent developer documentation and support materials to ensure a frictionless integration experience for our partners. 📍Partner with our Crypto Partnerships lead to engage directly with exchanges, understand their technical and user experience needs, and translate them into a prioritized roadmap. 📍Define the product-level security and authentication model for our B2B services, ensuring our systems are robust and trusted. 📍Set and track KPIs laser-focused on the ultimate goal: maximizing end-user transaction volume driven through our partner network.
What You'll Bring
📍5-8+ years in product management, with a significant portion in a highly technical, API-first, or B2B product role. 📍Proven experience shipping API-first products. You are comfortable writing detailed API specifications, debating system architecture with engineers, and managing complex technical integrations. 📍Deep knowledge of identity and authentication systems, including SSO, OAuth, and the secure handling of user credentials. 📍Experience in fintech, crypto, or payments infrastructure is strongly preferred. You understand the nuances of moving and displaying financial data. 📍A balance of technical depth and partner empathy. You can command the respect of the engineering team while effectively communicating with external commercial and product counterparts. 📍Entrepreneurial mindset: you live and breathe building API products, obsess over developer experience, and build like a founder.
