Payabli is looking for a
to set the technical direction for ML at Payabli. A few models are already live and driving real decisions: reducing time-to-clear for risk reviews and scoring transactions and merchants. But that's the starting line, not the destination. We want to build a broad portfolio of models that make payments smarter and easier: automatically choosing the best payment method, reducing disputes and chargebacks, improving authorization rates, forecasting payouts, and more. We need a technical anchor who can both raise the bar on what's live today and stand up many new models from scratch, owning evaluation, monitoring, feature development, retraining, and a clear line from model performance to business impact.
The decisions you make in your first quarter (how we build and ship models here, what "good" looks like for ML) will be foundational for years as the function scales. You'll partner closely with product, engineering, and risk operations to find where models create the most leverage across the payments lifecycle and define what "good" means for ML at Payabli.
Set the technical direction for Payabli's model portfolio - both maturing what's live (transaction risk, merchant risk) and building new models across the payments lifecycle (payment method optimization, dispute/chargeback reduction, authorization rate improvement, payout forecasting, and beyond)
Establish the ML foundations the team will build on: experimentation workflows, model monitoring, drift detection, performance benchmarking, and incident response
Translate ambiguous payments problems into well-scoped modeling opportunities, and model performance into business terms (loss rates, approval/auth rates, dispute rates, review efficiency)
Raise the technical bar through influence and example: mentor ML engineers and set practices the future team inherits
Partner with product, engineering, and risk operations to own and prioritize the ML roadmap
We're looking for someone who meets the minimum requirements below. If you meet them, we encourage you to apply. Your skills and trajectory matter more than checking every box.
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
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.
At
, 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
— 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.
— When ACH returns spike or a card program hits a snag, you're the first in the war room. You don't shy away from hard problems—you chase them. You volunteer for the complex, messy challenges others avoid.
— 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.
— 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.
— 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.
