About the role

We're looking for a Staff Machine Learning Engineer to own the infrastructure that gets our models from development into product and marketing workflows. You'll partner with data scientists and product engineers to build deployment pipelines, feature stores, monitoring systems, and retraining infrastructure across both product and marketing use cases. The right candidate is a data scientist that can also build scalable data architecture: you care about how a model will run at scale, not just how it performs on AUC.

Duties and Responsibilities:

Product ML Engineering

Own the deployment and production lifecycle of models powering product experiences: coverage recommenders, user-to-channel routing, and agent assignment logic

Build and maintain feature pipelines that feed real-time inference for consumer-facing product surfaces

Implement automated monitoring and alerting for data drift, feature quality issues, and model degradation

Develop CI/CD pipelines and retraining infrastructure that let data scientists ship iterative improvements without engineering bottlenecks

Marketing ML Engineering

Deploy and operationalize marketing models: attribution, incrementality, and media mix and automate feedback loops to ad platforms

Build reliable data pipelines that deliver clean, timely inputs to marketing models and measurement workflows

Own model health monitoring and dependency management across the marketing model inventory

Qualifications and Skills:

7+ years in machine learning engineering, MLOps, or software engineering with a strong ML focus

Experience deploying and serving real-time production ML models integrated with consumer-facing products (AWS SageMaker or equivalent)

Strong Python engineering skills: software design, testing, CI/CD, package development, and SQL

Experience building and maintaining feature pipelines, feature stores, and workflow orchestration (e.g., Airflow)

Familiarity with Docker, container orchestration, and cloud infrastructure

Strong communication skills; able to collaborate fluidly with data scientists, product engineers, and non-technical stakeholders

Bias toward ownership; you see a gap in the infrastructure and close it

Working knowledge of ML methods: supervised learning, Bayesian models, causal inference, enough to debug a model without a data scientist in the room

Marketing measurement: attribution, media mix modeling, or ad platform integrations

dbt or data warehouse tooling

Experience in insurtech, fintech, or other regulated industries

Gets in the weeds without losing the bigger picture

Knows the tradeoffs between over-engineered infrastructure and pragmatic solutions, and picks the right one

Bridges data science and engineering, fluent in both worlds and trusted by both teams

Raises the team's ML engineering bar through code review, documentation, and mentorship
