About The Team
Rossum joined Coupa earlier this year. We brought the document understanding layer - our proprietary T-LLM (transactional LLM) architectures, which we design and train from scratch, and which read the world's messiest business documents in production, millions of them every week. Now we are pointing the same in-house research capability at a much bigger problem: not just reading the documents, but acting on them.
About the Role
Sourcing is where the money is actually decided.
We are expanding our AI Platform team in Prague with a Senior AI Platform Engineer to work on a Sourcing problem set – which suppliers get invited. How the event is structured. How bids that differ in price, lead time, quality, risk and carbon get compared at all. What a fair price even is. When to award, to whom, and how to split the award across suppliers. How to do auctions and autonomous bidding.
This broad problem set will not be solved by a single model. Solutions might come from a diverse set of fields
Recommendation and retrieval
Game theory
Forecasting and should-cost modelling
Combinatorial optimization
Multimodal document understanding etc.
You will collaborate with researchers to implement these heterogeneous workloads in a scalable production platform in the cloud. At the same time, you will design and develop infrastructure for dataset export, model training, and evaluation to allow Research to move fast.
You will work in a small, senior team of engineers - the group that built Rossum's production inference pipeline from scratch - with direct access to Product and the AI Research team. Ideas that work do not sit on paper; they roll into systems used at scale.

What You’ll Do
Design, build, and maintain a scalable, reliable, and cost-effective AI platform in the cloud. Collaborate with Research to understand model requirements and translate them into scalable infrastructure. Improve data pipelines, feature storage, experiment tracking, and model lifecycle workflows. Build tooling that accelerates experimentation, benchmarking, and reproducibility. Implement monitoring, observability, and reliability improvements across AI services. Participate in architectural discussions and contribute to long-term platform strategy. Partner with Product, Research, and other engineering teams to align platform capabilities with product needs. Maintain clear documentation and support knowledge-sharing across R&D.

What You Will Bring to Coupa
Must-Haves 5+ years of experience in product-minded software engineering, ML platform engineering, or infrastructure roles Proven track record of delivering ML solutions that drive measurable business and customer impact. Strong programming experience in a language suitable for ML such as Python Understanding of distributed systems, microservices, and cloud-native architectures. Experience with SQL databases (query optimization, database performance tuning, and schema design). Experience with ML tooling (e.g., experiment tracking, model registries, data pipelines). Strong problem-solving skills and ability to work in cross-functional R&D environments. Solid understanding of CI/CD, infrastructure-as-code, and observability tooling. Internal communication in English as a default. Nice-to-Haves Experience with training or serving AI/ML models at scale. Experience with building scalable, automated ETL/ELT pipelines and maintaining robust database architectures (SQL/NoSQL). Familiarity with data annotation workflows and dataset management. Experience with GPU workloads, batch/stream processing, or feature stores. Exposure to Intelligent Document Processing or Deep Neural Network architectures. Our Stack We try to keep our stack standardized and minimal: Python, RabbitMQ, S3, Postgres, Triton Inference Server. All deployed with Kustomize and Flux to a Kubernetes cluster in AWS.

Why Join Us
We train and deploy our own models: Proprietary T-LLM architectures, designed and trained in-house – not a wrapper around someone else's API.
Transaction volume that brings interesting scaling challenges in the cloud.
Real ownership, short path to customers: You frame the problem, choose the method, and see it working in front of buyers – no research-to-product handoff.
Global impact: Technology used every day by companies around the world.
Experiment-driven culture: Pragmatic delivery, and quarterly recognition for standout research contributions.
Compute and tools: Frontier LLMs on tap for your own work, and our high-end GPU and large-memory clusters to train on.
33 days off: PTO, personal days, your birthday and two company wellness days. Parental leave on top.
Prague, Karlín: Inspiring workspace and full tech setup, including a 200 m² terrace with views of Prague Castle.

The successful candidate’s starting salary will be determined based on permissible, non-discriminatory factors such as skills, experience, and geographic location.
