payabli - Staff Machine Learning Engineer

• 8+ years of ML engineering experience, with 4+ years building and shipping production models that drive real business decisions • A track record of owning modeling architecture and seeing big, hard-to-reverse decisions through to production • Breadth across model types and problem framing. You can stand up a new model in an unfamiliar domain, not just optimize an existing one • Proven experience taking models from prototype to production and owning them post-launch (monitoring, retraining, incident response) • Deep grasp of modeling tradeoffs: precision/recall vs. operational cost, explainability, latency, and regulatory/compliance considerations • Experience establishing ML processes and infrastructure that a growing team inherits • A high technical bar set through influence and example. You make the work and the people around you better, and you're as comfortable in the codebase as in a design review • Ability to communicate model behavior and business impact to non-ML stakeholders • Comfortable in a fast-moving startup environment; bias toward shipping • Payments, fintech, or lending experience: chargebacks, merchant risk, KYC/KYB, authorization/routing, or similar domains. Experience with risk, underwriting, fraud, or credit models specifically is a big plus • Familiarity with AWS ML tools (e.g. SageMaker), and experience with feature stores, training/inference pipelines, and MLOps tooling • An interest in growing into people leadership as the function scales. We expect technical leadership from this role from the start; whether you want to manage a team down the road is genuinely up to you, and there's a clear path if you do. • We think you'll love being part of our team because • At Payabli, you'll have a front row seat into building a high-growth venture backed fintech company. As a senior leader in Operations, you'll shape how the organization scales and be the driving force behind our AI-first operations strategy — directly influencing how we build, automate, and optimize for the future. You'll stretch yourself every day, learn a ton, grow alongside the company, and have a lot of fun building Payabli with us. We're a values driven company that cares deeply about our team, partners, and customers. Our north star values are: • 🤝 Team Love = Customer Love — You understand that when you build great products for your internal partners, they deliver exceptional experiences to merchants. You obsess over the platform partners and businesses that depend on every payout landing on time. • 🔥 Run to the Fire — When ACH returns spike or a card program hits a snag, you're the first one in the war room. You don't shy away from hard problems—you chase them. You volunteer for the complex, messy challenges others avoid. • 🔍 Little Things Count — You sweat the details because you know a single decimal error in a payout can damage a business. You double-check edge cases, validate every assumption, and understand that excellence lives in the details. • 💎 Truth Seekers — You give direct feedback, receive it with grace, and never let ego get in the way of finding the right answer. You document what you don't know, admit mistakes quickly, and hold yourself accountable in the open. • 🚀 Relentlessly Curious — You're constantly asking "what if?" and "why not?" You study how competitors solve problems, explore adjacent industries for inspiration, and never stop learning about the payments ecosystem. • We build technology that gets noticed and a workplace where people want to grow their careers. Our work has been recognized by some of the industry’s most respected organizations, including being named No. 43 on the 2026 Inc. 5000, marking our third consecutive year on the list. Payabli was also named to the 2026 Forbes Fintech 50, recognizing the most innovative private companies in financial technology, Inc.’s 2025 Best Workplaces, and Built In’s 2026 Best Places to Work in Miami. • WHAT WE CAN OFFER YOU
