Senior Software Engineer - Risk (AI & Automation)

At Mercury, every new customer who applies for a bank account represents a new star igniting in a vast universe of possibilities. Initially, it may seem like a mere spark, but a closer examination reveals an intricate constellation of identity verification, ownership checks, sanctions screening, and fraud signals—all interconnected by invisible forces. The Risk Engineering team acts as the guiding navigation system for this expansive universe. Our mission is to safely guide thousands of ambitious individuals through Mercury’s orbit each day—each with a unique trajectory, risk profile, and narrative. We operate at escape velocity: moving swiftly, making confident decisions, and safeguarding the system without hindering the builders who depend on us. When we excel, founders can open bank accounts in delightful minutes rather than days, without needing to worry about the underlying complexities. We are on the brink of a new era. We are developing intelligent AI systems that do not merely assess risk but can reason about it—systems capable of investigating, deciding, escalating, and learning. These agents will enhance our KYC Refresh, EDD, ODD, and compliance workflows, propelling our operations to unprecedented levels of efficiency and scale. Our goal: to reduce manual labor, detect risks earlier, make sharper decisions, and create experiences that are almost magical in their simplicity. Now, we invite you to join us. We are seeking a Senior Software Engineer who is inspired by the prospect of bringing intelligent automation to life within real production systems. We need someone eager to design and implement AI-driven workflows that can think in steps, adapt to new information, and orchestrate complex decisions across people, models, and services. If you view compliance not as red tape but as a fascinating systems challenge at planetary scale, we want you. If you are excited about building impactful AI that safeguards millions of dollars, opens doors for founders globally, and helps shape the future of banking, we would love to explore this journey together. *Mercury is a fintech company, not an FDIC-insured bank.
