Job summary

Qogita is seeking a data scientist to own end-to-end data science across our wholesale marketplace, from framing commercial problems to shipping models that matter in production. You will work closely with Product, Engineering, Finance, and Commercial to power pricing, matching, demand and product discovery.

You’ll combine classical modelling with modern applied ML, including experimentation and LLMs where helpful, and own ML systems end-to-end in a fast-growing European startup with hybrid

Qualifications

• 3+ years as a data scientist, applied ML engineer, or quantitative analyst.
• Track record of owning models in production, not just building them.
• Solid grounding in probability, statistics, and ML fundamentals.
• Strong Python and SQL; comfortable with large transactional datasets and Pandas/Scikit-learn.
• Experience collaborating on MLOps-style workflows and shipping with engineers.
• Able to communicate uncertainty and model limitations clearly to technical and non-technical audiences.
• Bachelor's or Master's in a quantitative field (Data Science, Statistics, Economics, Econometrics, Mathematics, CS, or related).

Responsibilities

• Build and deliver data science solutions across the stack: predictive models, ranking, demand forecasting, segmentation, pricing, experimentation, and LLM-powered features.
• Take ownership of business-critical ML systems end-to-end: problem framing, model design, deployment, monitoring, and production maintenance.
• Translate ambiguous business problems into tractable ML or statistical problems with clear success criteria, working with Product and Commercial.
• Apply quantitative methods (regression, causal inference, classical ML, and deep learning when useful) to pricing, demand, liquidity, supplier matching, catalogue enrichment, and related marketplace problems.
• Design and analyse experiments and A/B tests, owning statistical validity and turning results into actionable recommendations.
• Collaborate with Engineers to ship models via reproducible MLOps workflows: experiment tracking, model serving, alerting, and production monitoring.
• Communicate model choices, limitations, and trade-offs clearly to both engineers and non-technical stakeholders.

Job description

Wholesale is a $50 trillion market still working the way it did in 1950. 90% of transactions happen offline, over calls, catalogues and trade shows, and a product passes through four or five layers of distributors and wholesalers before it reaches a store, with every party deciding on a fraction of the picture. By the time it hits the shelf, it costs roughly 40% more than the maker charged. That inefficiency tax runs into the trillions, and everyone pays it every time they buy anything.

Qogita is building the operating system that replaces that chain: a single order book connecting the global market, the rails to move goods across borders, and a self‑learning system that does every job once, against real‑time data about the whole market. That puts data science at the core of the product. Forecasting reads what is actually selling in every market as it sells, a buyer's basket is assembled from every available seller and split across the optimal combination, and every trade writes a record that sharpens the next price, allocation and route. It is a hard problem, spanning physical goods, thirty national regimes in Europe alone and buyers who are increasingly agents, and it is already working: 95% of transactions involve no human touch, and the business is doubling every year.

The role

You're a data scientist with strong quantitative and ML chops who can move between classical modelling, experimentation, and modern applied ML (including LLMs where they're the right tool). You'll own end-to-end data science work across Qogita's wholesale marketplace: framing ambiguous commercial problems, building models that ship, and keeping them healthy in production. The Data Science team partners with Product, Engineering, Finance, and Commercial to build the intelligence layer behind pricing, matching, demand, and product discovery.

What you'll do

• Build and deliver data science solutions across the stack: predictive models, ranking, demand forecasting, segmentation, pricing, experimentation, and LLM‑powered features, depending on where the business need is greatest
• Take ownership of business‑critical ML systems end-to-end: problem framing, model design, deployment, monitoring, and ongoing maintenance in production
• Translate ambiguous business problems into tractable ML or statistical problems with clear success criteria, working closely with Product and Commercial
• Apply quantitative methods (regression, causal inference, classical ML, and deep learning where useful) to pricing, demand, liquidity, supplier matching, catalogue enrichment, and related marketplace problems
• Design and analyse experiments and A/B tests, owning statistical validity and turning results into recommendations teams can act on
• Collaborate with Engineers to ship models via reproducible MLOps workflows: experiment tracking, model serving, alerting, and production monitoring
• Communicate model choices, limitations, and trade‑offs clearly to both engineers and non‑technical stakeholders

What you'll bring

• 3+ years as a data scientist, applied ML engineer, or quantitative analyst, with meaningful exposure across ML methods and statistical modelling
• A track record of owning models in production, not just building them: maintaining, monitoring, and iterating as live infrastructure
• Solid grounding in ML and stats fundamentals: probability, supervised and unsupervised learning, and measurement/validation discipline
• Strong Python and SQL; comfortable with large transactional datasets and common DS/ML libraries (e.g. pandas, scikit‑learn, XGBoost, PyTorch or similar)
• Experience collaborating on MLOps‑style workflows (experiment tracking, serving, monitoring) and shipping with engineers
• Able to communicate uncertainty and model limitations clearly to technical and non‑technical audiences
• Bachelor's or Master's in a quantitative field (Data Science, Statistics, Economics, Econometrics, Mathematics, CS, or related), or equivalent experience

Nice to have (depth in one or more)

• Pricing and market economics: price theory, buyer behaviour, demand estimation, causal inference, experimentation with real commercial stakes
• Production LLM systems: RAG, evaluation frameworks, prompt/fine‑tuning trade‑offs, transformers and major model families, LangChain or similar
• Marketplace or B2B dynamics; AWS/GCP/Azure ML infra; Airflow, Docker, dbt, Snowflake, Lightdash or similar

• Base salary: €60,000 to €90,000 (Amsterdam) / £60,000 to £90,000 (London) depending on experience
• 26 days of annual leave, plus 4 additional personal days
• Company performance‑based bonus
• Attractive equity package
• Pension contributions
• Annual learning & development budget
• Office‑led culture with hybrid flexibility
• Dog‑friendly offices
• Home‑office setup package
• Office socials and annual company‑wide offsite
