Applied ML engineer in financial crime

Описание

Wise moves billions across borders every year. Behind every transaction is a decision: is this safe? Our ML systems make that call – at scale, in real time, across every market we operate in. Our Risk ML team is building the next generation of financial crime detection at Wise – investing in modern architectures like deep learning, graph neural networks, and foundation models to detect increasingly sophisticated fraud and money laundering patterns. We’re looking for a Staff Applied ML Engineer to lead this evolution: defining the architecture strategy, shipping production neural models, and building the blueprint that scales across FinCrime domains.

Задачи

• Designing and shipping ML and deep learning models for financial crime detection – sequence-based, graph-based, attention-based – serving real-time decisions at Wise’s scale
• Defining the architecture strategy for how Wise applies modern ML to risk – which model families, which serving patterns, which training paradigms
• Building the reusable end-to-end pipeline pattern – from experimentation through training to production deployment – that future models follow
• Evaluating and prototyping foundation model and embedding approaches for transaction representation across FinCrime domains
• Partnering with Data Science on model evaluation, experimentation design and causal measurement in domains where clean A/B testing isn’t always possible
• Mentoring engineers and data scientists on modern ML fundamentals, production best practices, and architectural decision-making

Требования

• Production experience shipping deep learning models at scale – systems serving real traffic under latency constraints
• Ability to make architecture-level decisions independently – model selection, training infrastructure, serving strategy – and explain the reasoning and tradeoffs
• Experience designing ML systems with hard latency and throughput requirements, including optimisation decisions (quantization, pre-computed embeddings, batching strategies)
• Strong fundamentals in deep learning: gradient dynamics, attention mechanisms, graph message-passing, sequence modelling
• Track record of influencing technical strategy across teams – you don’t just build, you shape direction
• Python, PyTorch (or equivalent), distributed training, ML pipeline orchestration

Будет плюсом

• Experience in FinCrime, fraud detection, AML, or regulated financial services;
• Experience with graph-based methods (GNNs, entity resolution, link analysis) in production;
• Foundation model fine-tuning or LLM evaluation experience;
• Experience establishing modern ML practices in organisations scaling their ML capabilities
