Software Engineer, Agent Experience

At AssemblyAI, a leading company in Voice AI technology, the Software Engineer for Agent Experience will join a rapidly growing team focused on advancing AI-driven voice applications. The company processes massive volumes of audio daily and supports millions of API calls, serving a diverse customer base from startups to large enterprises. This role is part of the Product Engineering team and offers significant ownership and growth opportunities in a flat, meritocratic culture that values deep technical involvement and innovation.

The engineer will focus on enhancing the experience of AI coding agents that integrate AssemblyAI's voice products, such as speech-to-text and text-to-speech services. Responsibilities include developing agent skills, improving machine-readable documentation, tuning prompts, and building integrations with popular coding agents like Claude Code and Codex. The role involves close collaboration with senior engineers and requires a hands-on approach to building and measuring agent-driven workflows to ensure seamless developer experiences.

Candidates should have at least two years of software engineering experience with strong full-stack skills in JavaScript or Python, along with practical familiarity using coding agents daily. The position demands clear technical writing, product sensibility for developer tools, and comfort working in an evolving, ambiguous domain. Experience with prompt engineering, API-first development, or voice AI technologies is advantageous. The role is remote within North America and emphasizes a culture of shipping impactful features rapidly while leveraging AI tools internally.
