We are seeking a JUNIOR MACHINE LEARNING ENGINEER for a StartUp specialized in Financial Asset in Barcelona.
This is a stable position with a permanent contract directly with the StartUp (we will handle the selection process). The salary range could be 25.000 – 30.000 euros per year, gross, including fixed salary and bonus, depending on experience.
They offer flexibility on where you work: fully on-site in Barcelona (Sarriá – Sant Gervasi), or any hybrid split — and the number of days is yours, not a policy.
They offer also a real learning budget — books, courses, and conferences.
A versátil-remuneration plan covering meals and transport.
Their edge is a proprietary corpus of Spanish judicial and financial documents that no foundation model has ever seen, and the machine-learning systems they build on top of it. They are a ~25-person firm that analyzes and advises on Spanish real estate and distressed debt (NPL/REO), and two of those systems sit at the center of the business.
This is a junior role with the reach of a much larger one. As an early, high-impact hire,



you would work across both systems — modeling and document AI — as one connected role, not two jobs. What you build shapes the analysis they stand behind and reaches real decisions in days, not quarters. You would work shoulder-to-shoulder with a sharp, multidisciplinary team: engineers, analysts, and specialists in finance and law.
Responsibilities:
-Pricing what almost nobody can price: Predictive and quant models across thousands of Spanish loan and property records — asset valuation, portfolio-performance forecasting, feature enrichment, tabular and time-series modeling. The numbers you produce guide real capital, so evaluation and calibration are where the craft lives.
-Teaching a model to read a courtroom.
-Legal and judicial documents — multi-column, table-dense PDFs where layout and position carry meaning, not flat text — turned into clean, structured data. OCR, layout-aware extraction, NER, and LL
