Position Description
As our Lead Data Scientist, you will collaborate with and shepherd the Data Science and Machine Learning team and will create data science, machine learning, and AI solutions to better address the needs of our constituents (students, alumni, faculty, researchers, staff, and community at large). You will have the chance to guide and continuously improve the ways in which we engage, educate, and empower people around the world, combining the best of human touch and technology scale, experimenting with everything from the latest AI algorithms and techniques to blended and immersive environments, multi-modal and varied-form content, and the most innovative research and teaching methodologies. You will be highly influential in advancing our LLM applications and guide teams towards impactful and ethical AI. We seek an expert who is eager to grow and disseminate GenAI model expertise across the organization.
In this role, you will translate the needs of our cross-functional stakeholders into user-facing applications that leverage NLP techniques and large language models (LLMs). As a Lead Data Scientist on our GenAI applications team, you will work on products like conversational search interfaces, chatbots, text summarizers, recommender engines, and more based on the needs of the constituents. You will partner with Product Managers, Machine Learning Engineers, Cloud Platform Engineers, and cross-functional partners to develop production-grade algorithms. Your innovations will drive value creation through personalized engagement, expanded reach, and experimental ways of learning that will continue the Harvard Business School leadership in education, business, and societal impact.
- Architect the overall framework and infrastructure for GenAI products like search interfaces, bots, summarizers, etc. Develop and implement techniques to optimize model performance to meet specific product goals.
- Collaborate closely with product management and engineering leads to align on technical roadmap. Guide engineering teams to effectively leverage LLM capabilities in product implementations.
- Establish protocols and systems for building fair, accountable and transparent LLM-based applications. Lead efforts to proactively assess and mitigate risks due to model biases or failures.
- Implement robust feedback pipelines, monitoring and corrections to ensure model safety.
- Design and oversee curation of high-quality datasets tailored for LLM training for each product. Build data science pipelines from feature generation, data visualization and models evaluation; design the solution, build initial code and provide documentation with ways of working to maximize time to value and re-usability.
- Communicate clearly and effectively to technical and non-technical audiences, verbally and visually, to create understanding, engagement, and buy-in. Contribute novel research and analyses to leading academic conferences and journals.
Basic Qualifications
- Minimum of seven years' post-secondary education or relevant work experience.
Additional Qualifications and Skills
- Bachelors/Advanced Degree in Mathematics, Physics, Computer Science, Engineering, Statistics, or 8+ years equivalent work experience.
- 3-5 Years Experience in developing a variety of machine learning models and algorithms in a commercial environment with a track record of creating meaningful business impact.
- Experience with production RAG pipelines and agentic information retrieval and search systems, with the ability to write production level code.
- Strong Python skills required.
- Minimum of three years' experience building production NLP and deep learning models using PyTorch/Tensorflow, along with using large language model architectures (BERT, GPT-3 etc.).
- Experience building advanced workflows such as retrieval augmented generation, model chaining, dynamic prompting, PEFT/SFT, etc. using Langchain and similar tools.
- Proficiency with various prompting techniques, with a clear understanding of tradeoffs between prompting and finetuning.
- Experience with finetuning embedding models and tuning vector databases to improve performance of semantic search and retrieval systems.
- Experience with cloud computing platforms - AWS.
- Prior experience in leading data science and machine learning focused on solving business problems and seizing business opportunities.
Desired/Preferred Qualifications:
- Proficiency in at least one open-source programming language (R, Java, C++ or another) and SQL desirable.
- Experience establishing model guardrails and developing bias detection and mitigation techniques for AI applications.
- Ability to mentor and lead others; provide hands-on technical guidance; conduct code reviews.
- Ability to simultaneously coordinate and track multiple deliverables, tasks and dependencies across multiple stakeholders/business areas.
- Experience working in agile methodology.
Additional Information
This role has the possibility of being remote or hybrid. We consider hybrid to be a combination of remote and onsite work at our Boston, MA based campus. HBS expects all staff to be onsite 3 days per week and departments provide onsite coverage Monday – Friday.
We may conduct candidate interviews virtually (phone and/or via Zoom) and/or in-person for this role.
Harvard Business School will not offer visa sponsorship for this opportunity.
Culture of Inclusion: The work and well-being of HBS is profoundly strengthened by the diversity of our network and our differences in background, culture, national origin, religion, sexual orientation, and life experiences.
