What You Will Need · Extensive experience architecting and delivering production-grade messaging or notification platforms at scale. · Hands-on experience with email delivery, push notifications (APNs, FCM) and SMS. · Knowledge of email deliverability and authentication (SPF, DKIM, DMARC) and SMS compliance (for example, 10DLC and short codes). · Proven ability to work with business stakeholders and translate their needs into technical direction. · Strong experience with modern backend and frontend engineering, including TypeScript and API design. · Proven technical leadership across architecture, standards and cross-team delivery. · Hands-on experience with AI coding tools and a point of view on how they change engineering work. · Degree in computer science, engineering or a related field, or equivalent practical experience. Added Bonus If You Have · Experience in banking, payments or financial services. · Experience with messaging providers or customer engagement platforms, such as Twilio, SendGrid, Braze or similar. · Hands-on experience spinning up an APNs system from scratch. · Knowledge of communication regulations and consent management in financial services (for example, TCPA and CAN-SPAM). · Experience building multi-tenant or white-label messaging for many brands. · Experience with headless content management systems and content modeling. · Experience with Model Context Protocol (MCP) or exposing platform capabilities to AI agents. · Familiarity with secure software development practices for regulated financial environments.
