Our client is a high-growth, YC-backed AI company at the forefront of voice automation for financial services. They are redefining how humans and machines communicate, building emotionally intelligent voice agents that can listen, reason, and respond with human-like nuance.

This is far from a typical AI prompt role. This is for a visionary hacker — someone who can dream five years ahead in voice AI, yet still spend evenings iterating on models, refining dialogue, and perfecting tone and pacing. If you live for the craft — if hearing an AI-generated voice makes you immediately think about how to make it more natural, persuasive, and human — this is the role for you.

The Role

As a Voice Agent Designer / Prompt Engineer , you will lead the design, testing, and continuous improvement of AI-driven voice agents. You will operate at the intersection of language, emotion, and engineering, shaping frameworks and dialogue systems that define next‑generation customer experiences. This role requires balancing long‑term strategic vision with hands‑on experimentation. You will shape the company’s voice AI roadmap while refining prosody, writing prompts, and debugging real‑time dialogue.

What You’ll Do

• Design and refine multi‑turn, emotionally aware conversational flows for AI voice agents.
• Translate complex business rules and compliance requirements into intuitive, human‑like dialogue.
• Tune and experiment with synthesis models to optimize tone, pacing, and emotional cadence.
• Conduct A/B testing and human‑in‑the‑loop QA to drive continuous agent improvement.
• Prototype tools and frameworks to scale voice agent quality across diverse use cases.
• Own the roadmap for voice capabilities, defining what “great” sounds like and leading the team to achieve it.
• Collaborate cross‑functionally with product, data, and operations to translate vision into production‑ready systems.

What You Bring

• 3+ years of experience in voice AI design, conversational engineering, or applied LLM prompt architecture.
• A portfolio or proven track record of production‑grade voice systems (bonus: fintech or regulated sectors).
• Hands‑on experience with OpenAI Realtime, GPT‑4o, ElevenLabs, Deepgram , or similar tools.
• A hacker mindset — you thrive on building, testing, and iterating.
• A balance of action‑oriented execution and long‑term strategic thinking.
• Deep curiosity about human communication — tone, rhythm, empathy, and persuasion.
• Comfort operating in fast‑paced, high‑stakes environments with autonomy and accountability.

This Role Is Not for You If

• You are broadly interested in AI but not deeply passionate about voice.
• You prefer theoretical debates over hands‑on experimentation.
• You seek a role with narrow scope or rigid boundaries.

Why This Role Matters

• This is a foundational hire — your work will touch every voice product the company ships.
• You will shape the long‑term AI strategy while remaining deeply involved in the craft, bridging technical excellence with creative intuition.
• You’ll collaborate with top operators from leading fintechs and AI labs, in a space where every experiment pushes the frontier of voice AI.
