Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US.

As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations.

Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow.

About the role

Synthesia Roleplay Sessions is a training tool that lets people practice real conversations with AI avatars. Instead of just watching training videos, learners do interactive roleplay exercises, like practicing a sales pitch or handling a customer complaint with an AI coach. The AI gives instant feedback so people know what they did well and what to improve.

Managers can use a dashboard to track which employees have completed their training, see how well they performed, and measure if the training actually improved their skills. The whole platform is built around learning by doing rather than just passive video watching.

For your ML engineer role, you'd be building the AI engine that makes the coaching work. That means creating the models that listen to what learners say during roleplay, score their performance, generate helpful feedback in real time, and decide how the AI avatar should respond next based on what the learner does.

This is an applied ML position, not a research one. We expect you to have a good understanding of ML but on the other side to be a good product-focused software developer as you will be expected to work on different products.


Please bring with you:

  • Ability to apply your machine learning knowledge to solve real product problems.

  • At least seven (7) years of experience as a software engineer, with at least 2 years at senior level.

  • Experience in a high-performing engineering team operating at scale, whether in a scale-up or established organisation recognised for strong engineering culture.

  • Strong alignment with commercial success.

  • Pragmatism and bias towards action. This role requires comfort with fast iteration.

ABOUT THE ROLE

We are looking for a Staff Data Scientist to join Socure's Watchlist Data Science team. Watchlist sits at the heart of global AML compliance — our platform screens hundreds of millions of entities in real time across sanctions lists, PEP databases, and adverse media sources for banks, fintechs, and payment companies worldwide.

As a Staff Data Scientist, you will work on the hardest problems in entity matching and classification: scaling our patented real-time matching engine, building advanced Natural Language Processing (NLP) models for Named Entity Recognition (NER) and Information Extraction, and bringing next-generation research to production. This is a senior individual contributor role with broad technical ownership and direct impact on a product that helps the world's financial institutions manage sanctions and AML risk.

WHAT YOU'LL DO

Data Quality & Enrichment

  • Improve the quality, coverage, and freshness of Watchlist's underlying data through next-generation ingestion pipelines.

  • Design and execute rigorous data quality analysis pipelines to identify anomalies, evaluate dataset health, and ensure high-fidelity inputs for downstream model training.

  • Apply NLP and AI to classify and enrich raw source data into normalized schemas — extracting structured entity attributes from unstructured sanctions, PEP, adverse media, and enforcement sources.

  • Expand multilingual capabilities to support global screening across Latin and non-Latin scripts.

Entity Resolution

  • Build and improve NLP systems that consolidate how watchlist identities are represented. Developing Information Extraction and Named Entity Recognition (NER) pipeline to deduplicate entities across lists and resolve aliases into canonical profiles..

  • Develop approaches to handle how entity profiles change over time as names, aliases, and sanctions status evolve.

  • Measure and benchmark entity resolution quality, driving continuous improvement in coverage and accuracy.

Match Engine & Risk Scoring

  • Design and scale advanced NLP models and algorithms that perform real-time name matching and identity classification across diverse, multilingual unstructured data sources.

  • Build multi-signal risk scoring that combines name similarity, entity type, geography, list type, and other attributes into unified, calibrated risk scores.

  • Maintain and improve benchmarking frameworks, golden datasets, and regression tests that keep the match engine at the highest levels of recall and precision.

Analytics, Tuning & Evaluation

  • Build models and analytics that help customers tune their screening thresholds to the right operating point for their risk appetite and entity mix.

  • Develop backtesting and counterfactual analysis capabilities so customers and internal teams can understand how model or threshold changes would affect screening outcomes.

  • Design evaluation frameworks for AI-powered autonomous decision systems — defining correct behavior, calibrating confidence thresholds, and monitoring for drift in production.

AML Risk Detection

  • As Watchlist expands into payment screening, build the mathematical analysis and feature engineering needed to detect AML risk patterns across transaction data and payment message fields.

  • Develop and maintain the AML taxonomy and risk signal library that underlies Watchlist's classification and detection capabilities.

  • Apply graph-based methods to surface indirect risk exposure — identifying entities connected to sanctions risk even when they are not directly listed.




Research & Technical Leadership

  • Lead technical initiatives across Watchlist Data Science and shape the team's long-term approach to entity matching, enrichment, and AI.

  • Collaborate closely with Product and Engineering to translate research into production-grade systems at scale.

  • Stay current with advances in NLP, large language models, and entity resolution; prototype and deploy relevant techniques (e.g., advanced NER, LLM-based extraction) to AML use cases.

  • Mentor peers and contribute to a culture of technical rigor and continuous improvement.

WHAT YOU BRING

  • Master's or PhD in Computer Science, Computational Linguistics, Statistics, Applied Mathematics, or a related field; or equivalent professional experience.

  • 7+ years of experience in data science or machine learning, with meaningful work in NLP, entity resolution, or information extraction.

  • Experience in AML, sanctions screening, adverse media, or financial crime detection is strongly preferred.

  • Hands-on experience building and deploying NLP pipelines for entity extraction, named entity recognition, and record linkage at production scale.

  • Familiarity with multilingual NLP and non-Latin script processing is a strong plus.

  • Experience with LLMs and agentic AI frameworks (e.g., LangChain/LangGraph) is a plus.

  • Strong proficiency in Python and major ML libraries (PyTorch, spaCy, HuggingFace Transformers).

  • Strong SQL proficiency and experience with large-scale data pipelines and production ML systems.

  • Excellent communication skills — able to translate model performance tradeoffs into compliance and business language for non-technical audiences.

Note: We cannot provide Sponsorship at this time.

You must be located in one of our talent hubs: New York, San Francisco, Seattle, or Miami.
