About the Team Security is at the foundation of OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity. The Security team protects OpenAI’s technology, people, and products. We are technical in what we build but are operational in how we do our work, and are committed to supporting all products and research at OpenAI. Our Security team tenets include: prioritizing for impact, enabling researchers, preparing for future transformative technologies, and engaging a robust security culture. About the Role We’re seeking an exceptional Principal-level Offensive Security Engineer focused on deep, hands-on penetration testing of OpenAI’s agent-powered products, infrastructure, and model-integrated application surfaces. You’ll assess complex systems end to end, identify realistic vulnerabilities, validate exploitability and impact, and partner closely with engineering teams to drive durable fixes.

As we continue to expand our global footprint, we're looking for passionate people to join our mission. If you're ready to help the world's best companies optimize their digital applications, we invite you to explore a career with us! Your opportunity New Relic is looking for a technically fluent Senior Product Marketing Manager to own product marketing for Logs, one of the most strategic parts of our observability.

This is a role for a product marketer who is equally comfortable going deep with engineers on ingest pipelines, parsing rules, OpenTelemetry, and query performance as standing in front of a customer or a sales kickoff audience explaining why it matters. Logs are where observability meets cost, scale, and AI, and the buyer is increasingly forced to choose between keeping all their data and keeping their budget.
