The Staff AI Engineer – Voice AI is a hands-on senior individual contributor role for an experienced engineer with deep expertise across AI/ML, LLM systems, software engineering, and distributed system design. This role will help architect, build, and scale Nextiva’s next generation of intelligent, real-time conversational and Agentic AI experiences.
As a Staff AI Engineer, you will operate at the intersection of AI engineering, real-time systems, system architecture, and hands-on software development. You will take ownership of complex AI capabilities from experimentation and early-stage technical solutioning through architecture, implementation, evaluation, production deployment, and continuous improvement.
This is not an architecture-only or research-only position. We are looking for someone who remains deeply hands-on, writes production-quality code, understands modern AI systems in depth, and can translate rapidly evolving AI technologies into reliable, scalable, low-latency production systems.
You will work across the complete Voice AI stack — including streaming audio, ASR, TTS, LLM reasoning and orchestration, tool/function calling, RAG and knowledge systems, agentic workflows, context and memory management, and real-time communications. You will help build AI agents capable of reasoning, maintaining context, interacting with enterprise systems, and executing complex multi-step workflows while delivering natural and reliable conversational experiences.
The role also carries significant technical leadership responsibility. You will drive architecture and design decisions, solve ambiguous technical problems, mentor engineers, influence engineering direction, and collaborate across Nextiva teams to advance the Voice AI platform.
