Verisign helps enable the security, stability, and resiliency of the internet. We are a trusted provider of internet infrastructure services for the networked world and deliver unmatched performance in domain name system (DNS) services.
We are a mission focused, values driven company where each individual can contribute to building a stronger, more secure internet. We offer a dynamic and flexible work environment with competitive benefits and the ability to grow your career.
We are building a new engineering team responsible for establishing and operating the company's on-premises Artificial Intelligence and Large Language Model (LLM) platform. The Principal Engineer will serve as the senior technical authority for the platform and will help define how AI capabilities are safely, reliably, and effectively implemented throughout the company.
This is a hands-on technical leadership position. The successful candidate will combine strong systems and infrastructure engineering skills with practical knowledge of modern LLMs, inference platforms, developer tooling, and AI-assisted workflows in an enterprise environment.
The Principal Engineer will have substantial influence over architecture, technology selection, engineering standards, operational practices, and the long-term technical direction of the platform. This must be accomplished while continuing the Protect / Grow / Manage framework that guides the company.
Key Responsibilities:
Serve as the principal technical authority for the company's on-premises AI and LLM architecture
Design, implement, operate, and evolve production LLM inference platforms
Evaluate and recommend models, inference engines, developer tools, agent frameworks and supporting technologies
Develop repeatable evaluation methodologies for determining model quality, performance, reliability and suitability for company workloads
Work with Information Security teams to design secure mechanisms for applying LLMs to proprietary source code, internal data, documentation, and analytical workloads
Develop and work with engineering teams to create the most appropriate AI-assisted software engineering capabilities. This includes coding agents, tool use, repository integration, retrieval systems, and related developer workflows
Enhance existing engineering practices and update them to perform, model deployment, upgrades, rollback, observability, capacity planning and incident response
Work closely with security and infrastructure teams to establish appropriate controls for sensitive corporate information
Evaluate emerging AI technologies and distinguish technologies suitable for production use from experimental or immature approaches
Prototype new capabilities and convert successful experiments into reliable production services
Mentor other engineers on the AI platform team and provide technical leadership across organizational boundaries
Work directly with internal users to identify high-value applications for AI, including software development, data analysis, automation, and knowledge retrieval
