Senior Data Scientist

Remote

This is a fully remote opportunity with hybrid available to those local to Boston.

Gradient AI:    

Gradient AI is the decision-intelligence partner for the insurance industry, giving customers an advantage in how they make decisions by revealing risk others miss and translating it into stronger performance and real-world impact. Our platform harnesses a vast industry data lake – tens of millions of policies and claims enriched with economic, health, geographic, and demographic signals – integrating cleanly with existing workflows to make complex risk clear, usable, and actionable. Our customers include carriers, brokers, consultants, and specialized insurance organizations across the industry.  We are backed by $56M in Series C funding and scaling fast – and it's an exciting time to join the team! 

About the Role:    

We are looking for a Senior Data Scientist to advance our core AI models and drive them to market in collaboration with data science, product, and engineering partners. In this role, you will own well-scoped models end-to-end – working independently to ship measurable uplift on the AI capabilities at the heart of our products. 

How you will make an impact: 

  • Leverage the best of modern deep learning & large language models with traditional data science techniques to create powerful hybrid models with real uplift. 
  • Brainstorm, prototype, prove, deploy, and realize the value of your work in market quickly. 
  • Everything you would expect on a world-class data science team solving world-class problems.  Big data.  Federated learning.  Unstructured data challenges.  Timeseries and sequence modelling.  A self-serve buffet of techniques from GLMs to XGBoost to Transformers. 
  • Tell stories with your data.  Inspire trust in customers, stakeholders, and prospects by turning murky math into a powerful message that drives the bottom line. 

Who you are and why we want to work with you:

  • You like getting things over the line.  You have an insatiable desire to deliver value now and improve next.  MVP perfection is achieved not when there is nothing more to add, but when there is nothing left to take away. 
  • You are not a software engineer, but you give them a run for their money.  You prefer Python to R and don’t understand why there is still a debate.  Jupyter is a necessary evil, and you’ve never met a command line that scared you away. 
  • You still do a better job than Claude, and you’re skeptical of your friends who say they never code any more. 
  • You love to take initiative and spearhead new projects, even if they are not well defined. 
  • You build systems bigger than you. You contribute to open source, build packages your peers want to use, or design frameworks to elevate your team.  Reuse is a strategy, not a buzzword. 

Skills needed to succeed:   

  • Bachelor's degree in Computer Science, Data Science, Biostatistics, Mathematics, or similar related field AND 3-5 years of professional data science experience building predictive models 
  • OR Master’s or Ph.D in Computer Science, Data Science, Biostatistics, Mathematics, or similar related field AND 1-2 years of professional data science experience building predictive models 
  • Hands-on comprehensive experience with deep learning frameworks such as PyTorch or TensorFlow, and an understanding of modern AI architectures (e.g., Transformers, Neural Networks, LLMs).  
  • Advanced proficiency in Python and its core data science ecosystem (e.g., Pandas, NumPy, Scikit-learn, LightGBM, etc.)  
  • Strong technical communication and collaboration skills within agile squads and DS leadership 
  • Familiarity with SQL, Relational databases, and cloud environments like AWS/Azure/Google/Databricks 
  • MLOps and hands-on experience taking models from notebook to production — Experiment tracking, packaging, containerization (Docker), model serving and APIs, CI/CD, and pipeline orchestration 

Bonus Qualifications:

  • Fluency with actuarial methods and working with actuaries is a plus  
  • Familiarity with healthcare and medical data 
  • Familiarity with underwriting and claims, or predicting long-tailed and/or rare events 

What We Offer:  

  • A fun, team-oriented startup culture.  
  • Generous stock options - we all get to own a piece of what we’re building.  
  • Unlimited vacation days.  
  • Flexible schedule that supports working from home.  
  • Full benefits package includes medical, dental, vision, 401k, paid paternal leave, and more.  
  • Ample opportunities to learn and take on new responsibilities.  

We are an equal opportunity employer. 

Salary Range: $135,000-165,000k base salary annually.

This role is also eligible for an annual performance bonus, equity grant, and a comprehensive benefits package. In accordance with the Massachusetts Pay Transparency Law, we are providing a good-faith salary range for this position at the time of posting. The actual salary offered will depend on the level at which the candidate is hired, as well as their experience, skills, qualifications, and location. Compensation may grow over time through merit-based increases, promotions, and company-wide adjustments. If your salary expectations fall outside this range, we still encourage you to apply so we can have a conversation.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
