[Hiring] Staff Machine Learning Engineer @Root Insurance

Role Description

Price is the most important component of an insurance product, with the ability to drive customer delight through lower prices unlocked by state-of-the-art predictive modeling. The Pricing Platform team owns the foundational technology that powers the R&D and production lifecycle for Root’s most critical machine learning models. This platform is a cornerstone of Root’s strategic goal of becoming the best in the world at pricing and automation.

In this role, you will help build the next generation of Root’s machine learning platform for pricing, creating the infrastructure that allows researchers to move rapidly from experimentation to production. You will work closely with researchers on problems including:

• Feature pipelines and feature stores
• Reproducible model training and orchestration
• Model registries and versioning
• Automated validation
• Model serving
• Production observability
• Tooling that ensures consistency between research and production

You will also explore how emerging LLM technology can revolutionize the data science workflow, improving the way models are developed, tested, deployed, and maintained, with the goal of dramatically reducing the time and effort required to turn new research into production pricing models.

As a Staff Machine Learning Engineer , you are the technical leader of the team, owning long-term architectural design of the platform, the versioned contracts between data, features, models, and pricing, and the technical strategy that makes pricing models deployable with self-serve technology. Your influence is cross-team, spanning platform teams, their dependencies, and the interface with Data Science and Actuarial.

This is a hands-on role. You design, you write and review code in the most critical parts of the system, and you are accountable for the technical coherence of the platform over time.

Qualifications

• 10+ years of software engineering experience, with a demonstrated track record of designing and delivering business-critical ML platforms, data platforms, or similarly complex distributed systems
• Demonstrated architectural ownership of production ML infrastructure, including systems such as feature pipelines or feature stores, model training and orchestration, model registries and versioning, model serving, or research-to-production infrastructure
• Strong system design and distributed systems expertise, including experience designing reliable, scalable data processing systems and well-defined interfaces between complex systems
• Experience designing systems that provide strong guarantees around reproducibility, lineage, versioning, training-serving consistency, and production correctness
• Working knowledge of the ML lifecycle and the engineering considerations involved in training, evaluating, deploying, and operating models in production
• Demonstrated ability to establish technical direction in ambiguous problem spaces and translate long-term architectural goals into incremental, executable plans
• A track record of creating technical leverage across multiple teams through shared platforms, abstractions, standards, or tooling
• Demonstrated ability to influence technical direction across teams without direct authority and mentor senior engineers on architecture and system design
• Strong experience collaborating with Data Scientists and researchers to understand research workflows and translate their needs into scalable platform capabilities
• Proficiency with Python and modern ML and data tooling
• Excellent written and verbal communication skills, with the ability to communicate effectively across Engineering, Data Science, Product, and leadership

Requirements

• Define the long-term technical roadmap that accelerates pricing innovation through ML tools and workflows that improve the end-to-end pricing R&D process, balancing iterative delivery with the long-term vision for the platform
• Work closely with researchers to define platform needs that improve R&D ergonomics from data readiness through feature engineering, model fitting, serving, diagnostics, and monitoring
• Define the architecture and versioned contracts connecting data, features, models, and production pricing, ensuring the platform remains reproducible and technically coherent as it evolves
• Automate end-to-end workflows, leveraging LLM technology to power agentic data science workflow automation
• Write and review code in the most critical parts of the platform and drive technical design across systems and cross-team dependencies
• Mentor senior engineers in architecture, platform design, and best practices in ML engineering
• Set standards for reliability, observability, reproducibility, and correctness across the platform’s systems

Benefits

• Salary Range: $188,800 - $265,000 (Eligible for competitive bonus and equity offering)
• Root is a "work where it works best" company, supporting you working in whatever location that works best for you across the US.
