Senior Data Scientist, LLM App Development



The Role: 

Brightloom is creating an entirely new category of software-as-a-service for consumer brands — the Customer Growth Platform. This first-of-its-kind platform enables automated digital engagement and personalized loyalty programs to transform customer experiences while delivering predictable and repeatable lifetime value growth for brands.

As a Senior Data Scientist on our AI tool development team, you will play a crucial role in developing and optimizing an AI-powered tool designed to revolutionize how consumer brand operators understand and utilize their data. Your expertise will be instrumental in creating a tool that not only answers complex queries but also assists in assembling SQL queries to access and analyze consumer sales data efficiently. In addition to new product development, you will play a key role in maintaining and improving our existing machine learning based segmentation processes that the Customer Growth Platform is composed of. 

What You’ll Do:

  • Optimization of Large Language Models (LLMs): Fine-tune and optimize LLMs to effectively interpret user queries and generate precise SQL queries for data extraction and analysis.

  • Prompt Engineering: Develop and refine prompts to ensure the AI tool accurately understands and responds to a wide range of data-related queries, from complex analysis to general industry questions.

  • Collaborative Backend Engineering Support: Collaborate with our backend engineering team to contribute to the management and enhancement of key backend components. This includes assisting in the refinement of user input processing, ensuring accurate model output tracking, and facilitating seamless integration with our existing data infrastructure.

  • Data platform design: work your way up the Data Science Hierarchy of Needs.  You’ll partner with software engineering and product management counterparts to design our data and machine learning infrastructure, including collection, storage, processing, experiment design, modeling, and finally automated optimization.

  • Predictive modeling and data products: you’ll be the primary contributor on the models that power our forecasting and recommendations, which are at the core of this role and our Customer Growth Platform offering.

About You:

  • 5+ years of demonstrated success using machine learning model development to solve business needs

  • Expertise in Python’s core libraries and data structures, with the ability to write clean, efficient, and modular code.

  • Proven experience in working with large language models, natural language processing, and SQL.

  • Strong background in machine learning, AI technologies, and prompt engineering.

  • General knowledge of best practices in software development including unit testing, continuous integration, and code documentation.

  • Experience with Python libraries and frameworks that handle large datasets or big data environments such as Spark (PySpark), Dask, or Hadoop.

  • Strong written and oral communication skills

  • Graduate degree in a quantitative discipline a plus, such as Statistics, Mathematics, Data Science, Business Analytics, Economics, Finance, Engineering, or Computer Science

About Us:

At Brightloom, we are working to create meaningful relationships between people and the brands they love. Our Customer Growth Platform (CGP) offers a first-of-its-kind SaaS approach to automated AI-driven, predictive personalization. Previously, these types of capabilities were exclusive to larger brands who have entire teams of people focused on marketing and customer analytics. The CGP is built upon proprietary models that show and tell brands what to do next, so they don’t have to hire teams to build models, guess at rules, run experiments, and then interpret the results. The CGP models do this work, so the marketer doesn’t have to. We’re obsessed with taking something that’s really hard, complicated, and expensive and turning it into a service that’s simple and affordable for all consumer brands, not just industry leaders.

What We Offer:

  • Fun, creative and collaborative remote work environment 

  • Health, Dental & Vision Insurance Coverage

  • Life Insurance, Short-Term Disability, Long-Term Disability

  • Flexible Spending Account & Health Savings Account

  • Unlimited PTO
