Team &

Role Overview :

The Responsible AI team at Linked In serves as the centralized hub of excellence for AI and Data Science, spearheading the technical and organizational strategy to ensure trust, compliance, and safety for all Linked In members and clients. We ensure Linked In's AI solutions are aligned with principles of Fairness, Inclusion, Transparency, and now, advanced post-training LLM alignment work. Our work involves fine-tuning and aligning large language models with Linked In's core principles, focusing on critical areas such as privacy, fairness, explainability, safety, hallucination reduction, and robustness.

This team drives applied research and the development of scalable, industry-leading solutions across Linked In's AI platforms, models, and products.

Location:

At Linked In, our approach to flexible work is centered on trust and optimized for culture, connection, clarity, and the evolving needs of our business.

* Develop privacy-first training algorithms and techniques

* Develop evaluation and auditing techniques to measure the privacy of training algorithms

* Design and prototype privacy-preserving machine-learning algorithms (e.g., differential privacy, secure aggregation, federated learning) that can be deployed at enterprise scale.

* Measure and strengthen model robustness against privacy attacks such as membership inference, model inversion, and data memorization leaks-balancing utility with provable guarantees.

* Develop internal libraries, evaluation suites, and documentation that make cutting-edge privacy techniques accessible to engineering and research teams.

* Lead deep-dive investigations into the privacy-performance trade-offs of large models, publishing insights that inform model-training and product-safety decisions.

* Define and codify privacy standards, threat models, and audit procedures that guide the entire ML lifecycle-from dataset curation to post-deployment monitoring.

* Collaborate across Security, Policy, Product, and Legal to translate evolving regulatory requirements into practical technical safeguards and tooling.

* Provide technical leadership and mentorship to a team of engineers, fostering a culture of innovation and excellence.
