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 Data Capture Research team in Prague with a Senior Data Scientist to work on Sourcing.

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.

For a researcher this is unusually open ground - not one model family, but several, on the same data:

• Recommendation and retrieval. Supplier discovery: matching demand to the right suppliers across a 10M-node network.
• Forecasting and should-cost modelling. What this category, in this region, at this volume, should cost right now.
• Game theory and mechanism design. Auction formats, bidding behaviour, incentives, and competitive dynamics between real counterparties.
• Combinatorial optimisation. Award allocation under volume, capacity and multi-sourcing constraints.
• Multimodal document understanding. RFPs, specs, quotes and contracts carry the actual requirements - and our T-LLM foundations already give us a head start there.

Part of the work is choosing the right instrument for each - neural networks, gradient boosting, optimisation, bandits, mechanism design - instead of forcing one.

Very little of this has been built with modern ML yet. That is the point of the role: real greenfield problems, a dataset nobody else has, and a product that ships to companies whose margins depend on getting these decisions right.

You will work in a small, senior team of researchers and engineers - the group that built Rossum's production models from scratch - with direct access to Product and the AI Platform team. Ideas that work do not sit on paper; they roll into systems used at scale.

Why Join Us

• Greenfield problems in a mature product: Modern ML has barely been applied to sourcing, inside a platform that already has the users, the workflows and the data.
• Data nobody else has: $10 trillion of transacted spend, 10M+ buyers and suppliers, and the documents behind all of it.
• We train our own models: Proprietary T-LLM architectures, designed and trained in-house - not a wrapper around someone else's API.
• 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.
• Conferences: A budget to attend the ones that matter in your field.
• 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.

• Global Wellness Days: Enjoy two designated, company-wide paid wellness days off each year (typically the first Friday in March and the last Friday in September) so the entire global team can unplug, step away, and recharge together .
• Birthday Time-Off: Celebrate your day! Coupa provides a paid day off on your birthday or another day of your choice within your birthday month .
• Volunteer Time Off (VTO): Giving back is in our DNA. We offer 40 hours of paid VTO annually to support the community initiatives and volunteer programs you are passionate about .
• Employee Assistance Program (EAP): Access free, confidential, 24/7/365 counseling and resources for emotional support, work-life solutions, financial advice, legal guidance, and support for new parents .
• Business Travel Protection: Travel with peace of mind. Zurich Travel Assist provides medical, safety, pre-trip planning, and emergency support during any business travel .
• Referral Bonus Program: Share the Coupa experience! Receive generous monetary referral bonuses when you successfully refer talented friends or acquaintances who are hired into open roles .
