Who are we?

At Finastra, we’re a global leader in financial services software, dedicated to expanding access to financial services and shaping what’s next for the industry. Our technology powers mission‑critical solutions across Lending, Payments and Universal Banking, supporting over 7,000 customers, including 80% of the world’s top 50 banks, in more than 110 countries.

Role overview

We are hiring an Applied Data Scientist to build predictive ML models for our core banking products and to use LLMs to accelerate experimentation, test product ideas, and evaluate response quality. This role sits between product thinking, machine learning, and applied AI experimentation.  We need someone who is strong in predictive modelling, comfortable working hands-on with data and code, and equally comfortable using LLMs to prototype new capabilities, benchmark model behaviour, and design practical evaluation frameworks. You will work across use cases such as prediction, classification, recommendation, semantic matching, extraction, and intelligent workflow support, and you will partner closely with product, engineering, and domain teams to turn ideas into product capabilities.

What you do

• Build predictive ML models for product use cases in core banking.
• Own the AI/ML modelling lifecycle from problem framing and feature design through training, validation, testing, and performance analysis.
• Use LLMs to test new product ideas quickly, including AI assistants, summarisation, extraction, classification, semantic matching, and workflow support concepts.
• Design and run evaluation frameworks for LLM-based capabilities, including benchmark sets, rubrics, error taxonomies, human review loops, and offline versus online quality measurement.
• Improve LLM response quality through prompt iteration, retrieval design, grounding, and targeted experimentation.
• Work with product managers and domain experts to translate banking problems into measurable ML and AI approaches.
• Partner with AI platform and engineering teams to hand over models and evaluation assets for production deployment.

What we are looking for

• Strong hands-on experience building predictive machine learning models.

• Strong Python and SQL skills, with good software engineering habits.

• Experience with common ML tooling such as XGBoost, LightGBM, TensorFlow, or PyTorch.

• Good understanding of feature engineering, data preparation, model validation, and performance trade-offs.

• Practical experience with LLMs, including prompt design, prompt testing, benchmarking, and response evaluation.

• Ability to design evaluation methods that are rigorous and useful, not just technically neat.

• Good judgement on whether offline metrics genuinely map to user value and product quality.

• Strong communication skills and comfort working with cross-functional teams.

Ideal Candidate Should Have

• Experience with Databricks, Azure AI Foundry, Prompt Flow, Azure OpenAI, or similar.

• Experience with retrieval-augmented generation, embeddings, vector search, or hybrid search.

• Experience in financial services, fintech, or other regulated domains.

• Experience with annotation workflows, model comparison frameworks, or LLM observability tooling.

Example technologies

Python, SQL, Databricks, MLflow, Azure AI Foundry, Azure OpenAI, PyTorch, TensorFlow, scikit-learn, XGBoost, LangChain, LangGraph, vector databases, Azure AI Search.
