Lead Machine Learning Engineer - Servicing and Data Engineering  

We’re looking for a Lead Machine Learning Engineer to join our growing Servicing ML and Data Engineering Team in Tallinn (or Budapest, Tallinn preferred). 

This role is a unique opportunity to scale and advance the impact of Data Science in Servicing tribe – namely Fincrime, KYC and Customer Support squads. What you build will have a direct impact on Wise’s mission and millions of our customers.

About the Role: 

Our team is responsible for:

1) removing bottlenecks from Data Science workflows,

2) providing ML tooling for experiments and pipelines,

3) developing Wise’s Feature Platform.

Moreover, we are responsible for driving high priority projects from proof-of-concept to MVP, to service / tooling, in order to unlock cross-team impact.

We are looking for someone to own the evolution of ML experimentation tooling and model retraining pipelines – at first for Fincrime teams, then for other squads in Servicing. You will co-own stakeholder management, roadmap, delivery and onboarding. You’re also expected to conduct presentations, demos and workshops, in addition to maintaining good documentation and progress updates for their projects. Additionally, you will have the freedom to drive impactful proof-of-concepts of new methodologies and tooling that bridge a gap for two or more teams in Servicing tribe.

Here’s how you’ll be contributing:

• Software engineering: e.g. testing + CI/CD, monitoring/alerting + disaster recovery

• MLOps: Terraform and AWS infra, ML governance for hundreds of models

• Data Engineering: distributed processing at terabyte scale

• Science: prove value of new methodologies / algorithms applied to cross-team domains, estimate and measure impact, mentor junior members in experiment design

A bit about you: 

• Extensive experience with end-to-end distributed data systems, specially ML-centric ones;

• Previous experience as Data Scientist in large scale product team / business;

• Excellent Python and Software Engineering knowledge. Ability to work with Java if needed. Demonstrable experience collaborating with engineers on services.;

• Strong drive to solve problems for Data Scientists, with the ability to work independently in a cross-functional and cross-team environment;

• Good communication skills, ability to get the point across to non-technical individuals and back it up with data (and statistical analysis), to engage and manage project stakeholders;

• Strong problem solving skills with the ability to help refine problem statements and propose solutions taking effort-impact-scalability tradeoff into account.

Some skills that will make you stand out:  

• Apache Spark, Airflow, Iceberg, Kafka, dbt

• Scikit-Learn, XGBoost, MLFlow, Ray, PyTorch, Graph-tool (or similar)

• AWS (S3, EMR, SageMaker, Lakeformation), Terraform, Docker, GitHub CI/CD

• Knowledge Graphs (+ RAG), graph ML, probabilistic programming, A/B testing

The salary range we offer for this role is €65,000 - €83,000 + RSUs

We’re people without borders — without judgement or prejudice, too. We want to work with the best people, no matter their background. So if you’re passionate about learning new things and keen to join our mission, you’ll fit right in.

Also, qualifications aren’t that important to us. If you’ve got great experience, and you’re great at articulating your thinking, we’d like to hear from you.

And because we believe that diverse teams build better products, we’d especially love to hear from you if you’re from an under-represented demographic.
