Voice Agent Platform Engineer

Build the architecture, engine, SDKs, and product surfaces for Fish Audio's open realtime voice Agent platform.

About the Role

We are building an open realtime voice Agent platform for global developers and enterprise customers.
As a core engineer, you will work deeply across platform architecture and engine development, creating the infrastructure that external builders and companies can rely on.
This role spans low-latency voice agent systems, standardized interaction protocols, cross-platform SDKs, and product-facing implementation.

Own end-to-end delivery of the Agent platform from low-level engine work to product-facing business layers, turning capabilities into reliable product surfaces for complex real-world scenarios.
Participate in realtime voice Agent platform architecture and engine development, building a general-purpose foundation for low-latency use cases with high availability and scalability.
Define standardized interaction protocols and drive the development and maintenance of cross-platform SDKs so teams and customers can integrate efficiently.
Track trends in multimodal foundation models and Voice Agent technology, translating frontier capabilities into practical engineering systems that evolve reliably over time.

2+ years of software engineering experience, with strong proficiency in at least one mainstream backend language such as Python, TypeScript, or Rust.
Familiarity with modern frontend frameworks such as React or Next.js.
Understanding of mainstream LLM Agent architectures, including tool calling, context management, workflow orchestration, and related core mechanisms.
Agile engineering judgment and comfort with fast iteration cycles.
Strong self-direction and learning ability, with the ability to ramp quickly on new technologies.
Strong taste and care for interaction experience - you are not satisfied with merely making the system run.
