About the Role

We are hiring a Senior Machine Learning Engineer Scientist to lead the development of scalable graph-based and transformer-based modeling systems, along with production-grade ML pipelines. This role sits at the intersection of research and systems engineering and will help shape the next generation of relational foundation model for structured data.

You will own key architecture decisions, mentor engineers and researchers, and build high-performance ML systems that operate reliably at scale.

What You'll Do

Technical Leadership

.  Architect and drive the scalable development of foundation model for relational and graph data.

Design high-performance data pipelines for large-scale graph, relational, and tabular datasets.

Establish best practices for experimentation, reproducibility, evaluation, and deployment.

Define and execute the technical roadmap for ML infrastructure and modeling frameworks.

Geometric ML Knowledge

Develop and optimize:

      o Graph Neural Networks (GNNs), Graph Transformers, and Relational Transformers

      o Self-supervised, contrastive, and related pretraining strategies for structured data

Translate research innovations into robust, production-ready systems.

Scalable Systems & Infrastructure

Build and operate distributed training and inference pipelines with solid software design & architecture strategy.

Optimize compute efficiency (GPU/CPU utilization), memory footprint, training throughput, and inference latency.

Apply or evaluate techniques such as pruning, quantization, architecture search, and model compilation as needed.

Partner with platform teams to ensure smooth deployment, monitoring, and reliability in production.

Collaboration & Mentorship

Mentor ML engineers and applied scientists; raise the team's technical bar through guidance and review.

Collaborate closely with research, data, and product stakeholders to drive delivery and impact.

Required Qualifications

PhD or MS in Computer Science, Machine Learning, Applied Mathematics, Physics, or a related field, with substantial applied experience.

5+ years building and delivering ML systems end-to-end.

Strong hands-on experience with:

        o PyTorch

        o PyTorch Geometric and/or Deep Graph Library (DGL)

Experience of designing and developing distributed systems and scalable ML infrastructure.

Advanced Python proficiency and strong software engineering fundamentals.

Demonstrated ownership of complex ML projects from design through production. Experience scaling ML systems in cloud environments (e.g., Azure, AWS).

Preferred Qualifications

Experience building foundation models for structured, relational, or graph data.

Familiarity with transformer architectures tailored to graph and tabular domains.

Experience with distributed training frameworks (e.g., FSDP, DeepSpeed, Ray).

Deep expertise in:

         o Graph representation learning

         o Structured / relational modeling

         o Large-scale training systems

Publications in top-tier ML venues (e.g., NeurIPS, ICML, ICLR, KDD).

What We're Looking For

A systems-minded scientist who bridges research depth with engineering rigor.

A strong architectural thinker who can design scalable solutions with long-term maintainability.

A leader who mentors others and elevates engineering and research standards.

Passion for advancing structured-data AI and building platforms that deliver real-world impact.

Meet your team:

SAP is uniquely positioned to lead the next wave of AI by infusing intelligence directly into the business processes that run the world. Our team's mission is to develop Foundation Models for structured data, starting with the launch and continued evolution of SAP-RPT-1. As the first generation of our relational model portfolio, SAP-RPT-1 represents our commitment to pioneering new research in a domain where SAP's expertise in enterprise data structures provides an unmatched competitive edge. We are looking for innovators to join us in this journey to develop next-generation models with even higher impact, bridging the gap between cutting-edge AI research and the complex, structured reality of global enterprise data.
