Senior Machine Learning Engineer

About SurePay

Founded in 2016, SurePay is the leading account verification platform, relied upon by 250+ banks and thousands of organizations, to prevent fraud, misdirected payments, and reputational damage. Headquartered in Utrecht, we are scaling our platform and our team across Europe and beyond.

About the role

As part of SurePay’s strategic growth, we are expanding beyond our core Account Verification services to launch an integrated suite of actionable Fraud and AML risk intelligence products. To drive this, we have established a dedicated domain: Fraud Risk Intelligence.

You will join a focused cross-functional team of Engineers, Data Scientists, and Product Managers developing an enterprise-grade Machine Learning Platform.

Fraud detection requires split-second evaluation. The business goal of this role is to build, scale, and maintain a resilient, sub-millisecond real-time ML processing platform.

You will solve the critical challenge of converting experimental data science logic into high-performance, automated production systems—combining supervised risk models, unsupervised anomaly detection, and rule-based decision engines to stop financial crime in real time.

Responsibilities include:

• Product Discovery & Sparring: Partner with Data Scientists to understand the FRI problem space, discover new product possibilities, and connect technical implementations directly with client requirements and business context.
• Data Science Enablement: Support Data Scientists with their coding needs, guiding them on how to package and deploy ML models to production in a clean, safe, modular, and reproducible way (moving beyond raw notebook handoffs).
• API & Product Integration: Expose ML models to software engineers by designing high-performance microservice APIs with sub-millisecond latency, evolving new FrAML products according to planned market releases.
• Data Platform Evolution: Actively shape the next iteration of our internal data platform from an MLOps perspective, implementing real-time data streaming, aggregation points, and online feature store management.
• MLOps & Infrastructure Ownership: Architect, deploy, and maintain end-to-end AWS MLOps infrastructure using Infrastructure as Code (IaC), CI/CD pipelines, model emulation, and AWS SageMaker.
• Model Emulation & Operations: Set up automated monitoring, drift detection, continuous training loops, and model emulation environments to ensure low-latency API performance under heavy transactional loads.

About you

We are seeking a Senior ML Designer/Engineer with 8+ years of relevant software engineering and MLOps experience, with a proven track record of bringing ML models to production at scale. Someone who brings a practical balance of software engineering, cloud infrastructure, and data science literacy. You thrive in a discovery-driven environment, managing ambiguity to build rapid, non-over-engineered prototypes that scale cleanly.

If you have an industry background in Fraud, AML, or transactional risk scoring systems and/or familiarity with risk platforms such as NICE Actimize, RiskShield, FCRM, or Pega, that would be highly welcomed. Furthermore,

• AWS & MLOps Infrastructure : Deep hands-on experience with AWS SageMaker, Infrastructure as Code (Terraform/CloudFormation), and CI/CD pipelines for ML models.
• Production Software Engineering: Expert-level Python skills with experience building scalable microservices and sub-millisecond latency APIs.
• Real-Time Data Architectures: Hands-on experience designing real-time/streaming data pipelines and online feature stores (moving beyond batch-only processing).
• ML Frameworks: Practical proficiency packaging and deploying models using PyTorch, TensorFlow, Scikit-learn, or Apache Spark.
• Ability to quickly prototype, iterate, and adapt solutions within evolving, RFP-driven product requirements.
• Strong sense of accountability for end-to-end system resilience, from architectural design to operational maintenance.
• Excellent communication skills to interface effectively between Data Science, Data Engineering, and Product Leadership.

What we offer

• Competitive salary + 8% personal benefits budget (use it on training, more time off, or your salary)
• 25 holidays
• Hybrid working setup
• MacBook Pro, iPhone, and all the tech you need
• Travel costs covered (NS Business Card)
• Pension plan
• A culture of ownership, innovation, and autonomy

SurePay makes payments easier, more personal and even more secure. We are a fast-growing FinTech SaaS company and have secured our Series A funding in September 2021. SurePay stems from an innovation program of Rabobank, started in July 2016 and has been an independent BV since the beginning of 2020. SurePay is backed by two leading investors: Rabo Investments and Carlyle Europe Technology Partners . Both are highly experienced in scaling international B2B SaaS and FinTech companies. Their support reinforces SurePay’s mission to prevent payment fraud globally and accelerate our international growth.

SurePay's core values are; We Care , Build Together , Think Forward and Be Responsible . These core values are the driver's of our culture and can be seen as guidelines on our beliefs and behaviour. It defines what we find important as a company and the way we work together everyday.

We Care We see and call out the value in every person. That means showing support and appreciation, while pushing each other to reach our potential. Respect and safety are sacred: everyone gets to speak up and be themselves. And when things change or get hard, we deal with it head-on.

With customers, we listen actively and dig deep into their needs before offering solutions. We build trust through reliability and follow-through—recommending only what adds true value and going the extra mile to deliver.

Build Together Goals and camaraderie unite us. The road isn’t always paved, but no one here walks it alone. We show up as equals, put each other’s strengths to work, and celebrate every milestone together.

With customers, the conversation doesn’t wait for an annual survey. We build solutions with them, not just for them, and turn their input into action.

Think Forward Our bar never stops rising. We keep deepening our team’s expertise, improving our methods, and adopting new standards. We define success upfront, measure our progress, and adapt quickly when things change. Our energy goes where the impact is greatest.

Customers and partners get more than a product—they get a team that thinks ahead with them. We share what we’re learning about new fraud tactics and regulatory change, and we build our roadmap together.

Be Responsible Integrity is non-negotiable. Every day we make honest calls, own our commitments, and guard sensitive information like it’s our own. We’re stewards of the financial ecosystem, and we never lose sight of our environmental and societal impact.

We keep our promises and help customers and partners protect real people from losing real money. Our mission is clear, and we join forces with regulators, banks, and peers to take down fraud.
