Lead an approximately 10-person QA team across multiple services, managing testing, quality improvements, and stakeholder feedback while building AI-enabled verification processes. Remote work is available.
About this role
Develop and operate applications for HR, talent development, and organizational development. The role uses foundation models through APIs or open-source models and has responsibility from technology selection through architecture design.
Lead advanced LLM implementation beyond basic prompt engineering. Responsibilities include investigating effective prompt engineering, building RAG architectures, and carrying out RLHF, preference tuning, or fine-tuning as needed.
Connect existing data sources, including relational databases and BigQuery, with foundation models. Define the data needed to improve AI accuracy and plan its collection and expansion. Coordinate and negotiate with other departments and stakeholders responsible for those data sources.
In the HR domain, where correct answers and evaluation criteria can be ambiguous, select methods for assessing AI output accuracy and build the infrastructure needed to establish a continuing evaluation cycle. Design, develop, and operate applications for the relevant business areas.
Work with product managers and designers on UX/UI design and ongoing refinement. The team pursues user value through product improvement, evaluation methods, and evaluation infrastructure. It operates in a Scrum-style format, with knowledge sharing activities such as reading groups. The posting describes the team as small, open, and characterized by a culture of recognition.
The named technology stack includes Python, SQL for advanced extraction and investigation, Google Cloud, BigQuery, and GitHub. The role is positioned as a path toward technically leading difficult problems as a tech lead or engineering manager, or toward becoming an AI product manager who combines AI with HR domain knowledge.
