ML Software Engineering Lead

Global Payments, including Worldpay, is powering the future of commerce. We are seeking an experienced and visionary ML Software Engineering Lead to serve as the technical and functional leader for the Data Science Enablement engineering function, which owns the production development and ongoing operations of high-profile ML products.

You will be accountable for the technical strategy, operational maturity, engineering standards, platform capabilities, and long-term effectiveness of the ML software engineering practice. You will balance strategic leadership with hands-on technical contribution, dividing your time between setting technical direction and actively participating in architecture, design reviews, code reviews, and selected implementation efforts.

In this strategic role, you will collaborate closely with product, data science, platform engineers, and other product delivery teams to translate ML models and data-driven algorithms into robust, scalable, and low-latency production solutions. You will inherit a high-impact ML product portfolio with a mandate to grow and mature our capabilities to meet expanding business and technical needs.

What you’ll own

• Strategy and vision: Define the technical vision and strategy for ML software engineering initiatives, aligning them with business goals. Develop scalable capabilities to power real-time decisioning engines throughout the payment lifecycle and beyond. Enable rapid experimentation while ensuring robust, scalable, and secure deployment of ML solutions.
• Engineering and operational excellence: Establish and evolve engineering standards, operating practices, and technical governance. Mentor engineers, provide technical coaching, and promote technical excellence. Champion collaboration, continuous improvement, and knowledge sharing. Drive alignment across teams through technical influence, architectural guidance, and shared engineering standards rather than direct management authority. Identify capability gaps and drive improvements to tooling, automation, observability, and operational processes. Drive consistency in engineering practices and operational processes across teams delivering and supporting ML-powered products. Establish operational standards for production ML systems, including reliability objectives, observability, incident management, and support processes.
• Technical leadership and contribution: Guide the architecture, implementation, deployment, and operation of ML products and reusable components. Ensure systems and components meet requirements for scalability, latency, explainability, and regulatory compliance. Establish and promote best practices for ML software engineering. Stay abreast of industry trends and emerging technologies to drive adoption of modern tools, frameworks, and infrastructure. Contribute to QA and code as needed.
• Cross-functional collaboration: Partner closely with research-focused data science teams, business stakeholders, infrastructure support teams, data engineering teams, security/compliance teams, etc. to identify opportunities and incorporate ML into products and systems. Collaborate with other data science and engineering leaders to establish an operating model for machine learning R&D that optimizes end-to-end delivery of business value. Communicate complex technical concepts to non-technical stakeholders effectively.

What you’ll bring

• Bachelor’s or Master’s degree in Computer Science, Statistics, Mathematics, Engineering, or a related field (PhD a plus).
• 7+ years of ML software engineering, ML ops, ML engineering, or ML research experience.
• 5+ years of experience deploying large-scale, real-time ML models in customer-facing, production environments, including significant experience hands-on.
• 2+ years of technical leadership experience on an early-stage ML software engineering team.
• 2+ years of data science research experience.
• Proven experience developing microservices at scale (API design, monitoring, deployment strategies, containerization) in a cloud environment (preferably AWS and DataBricks).
• Strong understanding of the data science/ML research process.
• Strong understanding of software engineering, MLOps, and DevOps best practices.
• Strong Python skills, including in relevant libraries such as Pandas, NumPy, scikit-learn.
• Proficiency in SQL and NoSQL databases.
• Excellent communication, leadership, and stakeholder management skills.

It’s a bonus if you have

• Experience in a merchant acquiring, payment service provider, or card network environment.
• Familiarity with tokenization, real-time payments, and the authorization lifecycle.
• Experience in a large, complex organization in a highly regulated industry.
• Experience working in an agile environment.

Impact: Play a key role as the technical owner of high-profile ML products delivering meaningful business impact to merchants and advancing key pillars of the company’s strategy. Your work will directly influence the reliability, scalability, and evolution of critical production systems.
Autonomy: Take end-to-end technical ownership of your product area, with the freedom and responsibility to drive technical solutions, shape best practices, and deliver results in a fast-paced, supportive environment.
Collaboration: Join a cross-functional, high-performing team where your expertise is valued and your contributions make a real difference.
