Summary

Entry-level research scientist training self-supervised foundation models on financial data (bureau, transactional, graph) for credit risk, anti-fraud, acquisition and LTV tasks. Day-to-day: experiments and training runs in Python/PyTorch with MLflow, AWS and Snowflake, plus SOTA research and evaluations. Remote worldwide within GMT-2..GMT+5, with relocation support to hubs.

We are looking for a Junior Research Scientist to work on foundation models for financial data. Several of them already run in production on bureau, transactional and graph data; your work is to extend that line to new data domains and new downstream tasks — credit risk, acquisition, anti-fraud, LTV forecasting.

We work with Python, PyTorch, MLFlow, AWS, Snowflake and modern AI coding tools such as Claude Code, OpenAI Codex and Cursor.

This is a great opportunity for someone at the beginning of their career and who wants to work on large-scale, technically challenging projects.

Challenges that await you

  • Train self-supervised models on discrete sequences to beat the SOTA and achieve business impact in downstream tasks across Plata, such as: credit risk, transaction anti-fraud, acquisition and LTV forecasting.
  • Stay on top of SOTA research, applying the latest NLP and DL techniques to fintech models.
  • Work with large multimodal datasets: tabular, behavioral, transactional, device and network, text, time series, graphs.
  • Optimize the utilization of compute resources for both training and inference.
  • Own and develop solutions end-to-end, from idea to data collection to experiments to training runs to inference optimization to evaluating impact.
  • Perform rigorous evaluations.
  • Write articles and speak at industry conferences.

What makes you a great fit

  • Education: mathematics, engineering, computer science, artificial intelligence or another strong quantitative field.
  • Strong foundation in machine learning and deep learning, with hands-on experience building and experimenting with models using PyTorch and LLMs.
  • Understanding of dataset design and data mixing for deep learning training.
  • Demonstrated understanding of how to maximize the utilization of compute resources and efficiently perform experiments to validate research ideas.
  • Solid communication skills.
  • High autonomy and ownership.

Your bonus skills

  • Published research in machine learning or deep learning.
  • Personal projects or startup experience in AI, machine learning or deep learning.
  • Internship experience in research, ML or DL teams.
  • B1 or higher English level for effective communication with an international team.

Our ways of working

  • Innovative Spirit: A commitment to creativity and groundbreaking solutions.
  • Honest Feedback: valuing open, transparent communication.
  • Supportive Team: a strong, collaborative community.
  • Celebrating Achievements: recognizing our wins together.
  • High-Tech Environment: a team full of smart and revolutionary people who dare to challenge the status quo of incumbent finances.

Our benefits

  • Relocation support to one of our hubs — Serbia, Georgia, Mexico or Colombia — with assistance for the employee and their family.
  • Flexible work from one of our offices or remotely within time zones from GMT-2 to GMT+5.
  • Healthcare Coverage
  • Education Budget: Language lessons, professional training and certifications.
  • Wellness Budget: Mental health and fitness activity reimbursements.
  • Vacation policy: 20 days of annual leave and paid sick leave
